Published corrections

15 October 2026 — Chery P0562: a 12V pattern we had called documented: our Chery P0562 fault-code page pointed readers to “the family-wide 12V pattern documented across our Chinese-brand coverage”. The owner reports behind that pattern have not been verified, so the page no longer points to it and now gives our Chery problems research as its context. No reader reported this: we found the line on 7 October 2026, in a review of how our pages describe our coverage, and our technical reviewer ruled on 13 October 2026 that its removal needs this entry. Corrected 15 October 2026.
15 October 2026 — BYD owner guides: two rankings withdrawn: our BYD owner guides page said BYD had “the cleanest recall record of the four brands” we cover. The Australian Government vehicle recall register published a BYD Shark 6 recall, REC-006728, on 21 September 2026, and we had not measured the four brands’ recall records against each other. The ranking is withdrawn and not replaced: the page now describes the recalls we track for the brand, in Australia and the UK. The page also labelled its link to our Dolphin guide “the efficiency record”, a ranking that rested on a government figure naming no test cycle; the link now reads “Dolphin”. No reader reported this: our data-currency auditor raised the recall ranking on 19 September 2026 and the efficiency ranking on 17 September 2026, and our technical reviewer ruled on 13 October 2026 that their withdrawal needs this entry. Corrected 15 October 2026.
13 October 2026 — Chery C5: Chery removed its capped-price table, and our prices are now dated: our Chery C5 schedule page presented the C5 1.5T DCT capped prices as Chery Australia’s current official figures, and our Chery C5 page said those service costs were verified from Chery’s official program. That table is absent from our saved copy of Chery’s Capped Price Service page of 15 September 2026 and from the page as we read it on 30 September 2026, where the only C5 table was for the C5 Hybrid. Nothing we have read says the prices changed. Both pages now date the table to our reading of 20 August 2026 and say that Chery had removed it by 15 September 2026, and the schedule page asks you to get your car’s price from a Chery dealer in writing before you book. No reader reported it: our own saved copy of 15 September 2026 already lacked the table; our data-currency audit found the gap on 30 September 2026. Corrected 13 October 2026.
13 October 2026 — GWM Haval H6: what sets the service price tier — the warranty start date, not first registration: our H6 owner’s guide said H6 service prices are set by first-registration date. Our H6 service-schedule page said its prices are locked to first-registration date, priced the same GEN3 4WD at $1,760 or $2,060 over five services by whether it was first registered before or after 1 January 2025, and said no registration year is implied for its New H6 rows. GWM Australia’s capped-price service documents for the GEN3 H6 and the petrol H6 GT define the Customer Year by the warranty start date. We had put our own name on GWM’s defined term. A reader choosing a price column by registration date could have read from the wrong one. GWM’s terms do mention first registration: the price that applies is the one current when the car was first registered. Both pages now name the warranty start date. No reader reported this. We found it on 7 October 2026, in a search of our other GWM pages after our technical reviewer found the same error on our Jolion pages; he read the H6 documents’ definitions against our extraction record the same day. Both pages carry 20 August 2026 as their publication date; the sentences carrying the error are in our earliest copies of both pages, from 2 September 2026. Corrected 13 October 2026.
13 October 2026 — GWM Cannon: what sets the service price tier — the warranty start date, not first registration: our Cannon service-schedule page told readers to find the price column for their car’s first-registration year, and its search description gave the 2.0L’s prices by registration year, while the same page explained the “CY” columns correctly as the Customer Year, set by the warranty start date. The disclaimers on that page and on our Cannon owner’s guide said prices are set by first-registration date. GWM Australia’s capped-price service document for the Ute Cannon defines the Customer Year by the warranty start date. A reader choosing a price column by registration date could have read from the wrong one. GWM’s terms do mention first registration: the price that applies is the one current when the car was first registered. Both disclaimers now say so. Both pages now name the warranty start date. No reader reported this. We found it on 7 October 2026, in a search of our other GWM pages after our technical reviewer found the same error on our Jolion pages; he read the Cannon document’s definitions against our extraction record the same day. Both pages carry 21 August 2026 as their publication date; the sentences carrying the error are in our earliest copies of both pages, from 2 September 2026. Corrected 13 October 2026.
13 October 2026 — BYD Sealion 7 fluids: a coolant rating from another car: our BYD Sealion 7 fluids page described the motor-controller coolant as “Glycol OAT long-life, −40”. Neither Sealion 7 owner’s manual we hold (the Middle East edition the page cites and the 2025 Australian owner’s handbook) prints −40 for this coolant; the figure is the one the BYD Seal’s manual prints for its own coolant, carried across to the Sealion 7. We have withdrawn it. No reader reported this: our data-currency auditor found it on 28 September 2026, and our technical reviewer ruled on it on 9 October 2026. Corrected 13 October 2026.
9 October 2026 — GWM Jolion running costs: a register fuel figure given as a requirement, and a servicing gap given too narrow: our Jolion running-costs page said the 130 kW petrol Jolion “requires 95 RON” while the base petrol “takes 91”. Its only source for those figures was the Australian Government’s Green Vehicle Guide, which lists them in its engine description for each version. A register field evidences what the register recorded in that field, and nothing further: not which grades the car will accept, and not a fuel requirement from GWM. The page now attributes the figures to the register and tells you to check the grade for your car in its handbook or with a GWM dealer, and we removed “with the 95 RON catch on the 130kW” from the description in the page’s structured data. On 9 October 2026, our GWM Tank 500 running-costs page still gave its register fuel grades as requirements; it needs its own reading, and this entry does not close it. Our Jolion running-costs page also put the hybrid’s extra servicing cost over five years at “≈$100–180”. Against the petrol Jolion (Premium and Lux), GWM’s capped prices give a gap of $100, $180 and $195 across its three price tiers, so the top of our range was $15 short for cars on the build-date tier. The page now gives $100–$195. No reader reported this: our data-currency rotation noted both on 1 October 2026, and our technical reviewer ruled on both on 7 October 2026, after reading the page in full. Corrected 9 October 2026.
7 October 2026 — GWM Jolion: what sets the service price tier — warranty start date and build date, not first registration: our Jolion owner’s guide and our Jolion service-schedule page said the Jolion’s capped service prices depend on the car’s first registration date, and gave that as GWM’s “Customer Year” system. Our Jolion running-costs page said its servicing totals are set by registration date. GWM Australia’s capped-price service document for the Jolion defines the Customer Year as the warranty start date, and its third price tier, “September 2025 Build or after”, goes by the car’s build date. We had put our own name on GWM’s defined term. A reader choosing a price column by registration date could have read from the wrong one. The schedule page’s search description also put its $200–$690 range under the Customer Year; the top of that range is a build-date price. GWM’s terms do mention first registration: the price that applies is the one current when the car was first registered. The schedule page now quotes that rule separately. All three pages now name the warranty start date and the build date. No reader reported this. Our technical reviewer found it on 7 October 2026, reading the owner’s guide and the schedule page in full against GWM’s document; a search of our other pages the same day found it on the running-costs page. The owner’s guide and the schedule page carry 20 August 2026 as their publication date, and the running-costs page 21 August 2026; the sentences carrying the error are in our earliest copies of all three pages, from 2 September 2026. Corrected 7 October 2026.
7 October 2026 — GWM Jolion: spark plugs on the petrol Jolion (Premium and Lux) changed more often than we said, one transmission-fluid rule, and high-voltage coolant twice rather than at every service: our Jolion owner’s guide and our Jolion service-schedule page said the petrol Jolion (Premium and Lux) changes its spark plugs on a 40,000 km rhythm. GWM Australia’s capped-price service document for the Jolion prints four replacements on its sheet for the petrol Jolion (Premium and Lux): at 36 months / 40,000 km, 60 months / 70,000 km, 84 months / 100,000 km and 108 months / 130,000 km. After the first, each gap is shorter than 40,000 km, so an owner following our line would have changed the plugs less often than GWM asks. Both pages now print those four points; the schedule page also prints the three points on the S/Ultra and HEV sheets (36 months / 40,000 km, 72 months / 85,000 km and 108 months / 130,000 km) and says that plug changes after the fifth and last capped-price service fall outside capped pricing. On the transmission fluid, the owner’s guide said it changes “from” 55,000 km, and the schedule page gave 48 months / 55,000 km as its “first change”; the first wording is ambiguous, and the second implies a different interval afterwards. All three of GWM’s Jolion sheets give one rule, a change every 48 months or 55,000 km, whichever comes first; on the HEV the same rule applies to the hybrid transmission’s DHT oil. Both pages now print that rule. The coolant error ran the other way from the spark-plug error. Both pages said the HEV’s high-voltage coolant is changed at every service. On GWM’s HEV sheet, the battery’s state of health, its box and its high-voltage connectors are inspected at every service, and the high-voltage coolant is replaced twice in a schedule that runs to 145,000 km. Our line overstated the work; both pages now say twice. No reader reported any of this. On 12 September 2026 our data-currency rotation read both pages against GWM’s document: it found the spark-plug and coolant errors on the pages, and traced the “first change” wording to a second transmission-fluid stage in our own extraction record that no Jolion sheet prints. That record also carried the spark-plug error; it was corrected on 2 October 2026, after our technical reviewer ruled on it. The pages went on printing all three errors after 12 September 2026, until this correction. The pages carry 20 August 2026 as their publication date, and we have not been able to date the day the sentences carrying those errors went onto them: they are in our earliest copies of both pages, from 2 September 2026. Corrected 7 October 2026.
30 September 2026 — our Privacy Policy did not mention two headers the Cloudflare proxy added to responses from this site: the headers nel and report-to may ask a reader’s browser to send reports of network errors on this site to a Cloudflare address. Our own saved copies of the responses from the proxy carry them on 7, 10, 13 and 28 September 2026, and the copies of our Privacy Policy we saved on 13, 16, 19 and 22 September 2026 do not mention them. That omission is the second time the Privacy Policy has failed its own rule that it changes before the practice does; the 1 September 2026 entry records the first. We do not know when the headers started. The earliest record we hold of them comes from our own security check of 27 August 2026, which noted both headers by name on a response from our home page and did not keep their contents. The Privacy Policy now describes the headers, says who receives the reports, and lists them in its table of what is collected and by whom.
19 September 2026 — our Privacy Policy gave the analytics a start date our own account log does not support and gave it a bot purpose it never had — and this page repeated the date and the bot purpose in its 1 September entry below: the page said Cloudflare Web Analytics had run since 29 August 2026, switched on to see where visits come from and to keep harmful bots out. The date. The Web Analytics site in our Cloudflare account was created on 18 August 2026. One thread stays open: the script that was served named its site by a token we have not matched to the Web Analytics site the account names, so we do not say the two are the same, and we have not dated the day a script first reached a page of ours. Nothing was switched on for this site on 29 August: the whole event list for that day is seven entries, all of them Cloudflare’s own internal changes. The bot purpose. Web Analytics keeps no bots out. The bot-related change is three request-filtering rules created on 26 August 2026. The page now gives the analytics no start date and names the request-filtering rules as the bot measure; the 1 September entry below carries that correction at its head. These dates come from that account log and have not yet been through our technical reviewer. Corrected 19 September 2026.
9 September 2026 — MG ZS warranty and Hybrid+ fuel-grade corrections: We previously listed South African MG ZS cover as a 7-year/200,000 km vehicle warranty without a registration-date limit. MG South Africa’s current page applies to vehicles registered on or after 01/05/2026 and separates 5 years/150,000 km for the whole vehicle from 7 years/200,000 km for the Power/Traction Battery only on EV/HEV/PHEV models, whichever occurs first in each case. Our pages now make that split explicit; the current source does not resolve earlier registrations or publish the full terms it says dealers hold. The running-costs page also previously presented RON 95 as a single Hybrid+ requirement and used it in a pump-price inference. It now shows the unresolved official-source discrepancy: Australian Government GVG record 34202 for a ZS Hybrid+ released in 2024 says 91RON, while MG Australia’s MY26.5 brochure says RON 95 and above for both Hybrid+ columns. We do not choose between them or claim the variants are equivalent. Finally, our South Africa guide called the source row Battery | 1 year /10,000 km a 12V battery; the source does not name its type, and the page now says so. We found these issues during an internal staleness audit.
1 September 2026 — our Privacy Policy said there was no analytics after analytics had started: this entry said, when we published it, that Cloudflare Web Analytics was switched on for this site on 29 August 2026, to see where visits come from and to keep harmful bots out. The date and the bot purpose in that sentence are wrong; the 19 September 2026 entry above corrects them, and we mark that here rather than at the foot of this entry. Our Privacy Policy went on saying there was no analytics — in its opening line, in its table and in the closing invitation that told readers to count the script tags on the page — until we rewrote it on 1 September 2026. How long it said that while a script was being served we do not know: the two to three days this entry gave as that span were measured from the 29 August date the entry above denies, and we have not dated the day a script first reached a page of ours. Nothing about the script’s arrival was written in the files we publish: the script was in the copy Cloudflare served, not in anything we commit. It is the second time something was added to the copy the Cloudflare proxy serves that our own text did not account for. This entry had put that addition in the present tense and dated it from a Cloudflare setting; this entry now gives no start date, for the reason the 19 September 2026 entry gives, and it keeps to the past tense because it describes the Privacy Policy as it stood on 1 September 2026. The first addition was email-address obfuscation, described on that page on 27 August 2026 and switched off by the time we checked again on 1 September 2026, when our address stood readable in the page source five times over. Switching one feature off closed that case and not the class. The Privacy Policy, as we rewrote it that day, named the analytics and gave a start date, named Cloudflare as the party holding what it reports, stated that we have not measured what it stores in a browser rather than claiming it stores nothing, and said in the conditional that advertising and collection for analytical and marketing purposes may follow. Its verification invitation that day matched what we counted ourselves: two script tags on the pages we checked, three on the home page. No standing check of ours found this. It surfaced on 1 September 2026 in a live-page check we were running for a different reason — measuring the effect of switching email-address obfuscation off — when we counted the script tags and found one we had not written. The commands and their output are archived with the batch. No reader reported it. This entry describes the Privacy Policy as it stood on 1 September 2026.
30 August 2026 — BYD Atto 3 eight-year total, and a source line that claimed it as ours: our Atto 3 schedule page prints A services at $189, B services at $447 and an eight-year total of $2,390, and it still prints all three unchanged. Those three figures were not what we got wrong — we printed them as they reached us; the frame around them was. Our source line on that page ended “Totals are our arithmetic.” The total was never our arithmetic, and nothing on the page told the reader that the three figures do not reconcile. Four of each at those prices come to $2,544 — and no whole number of A and B services at those prices reaches $2,390 at all, because both prices divide by three and $2,390 does not. All three figures reached us the same way: BYD’s official program announcement, as covered by multiple independent outlets, not a dealer price table. The authorised network listed the Atto 3 among its models but published no price schedule for it when we checked on 29 August 2026, so we had no second table to check the figures against — but re-adding the rows of our own table needs no second table, and that is the check we had not run. The page now marks the total as reported rather than our sum and carries a note explaining the gap — we have not adjusted any of them into agreement with the others. The source line no longer claims the total as our arithmetic. The error was live for nine days before we caught it: the page published on 21 August 2026, and our language gate found it on 30 August 2026, during a closing pass. Our language gate now re-adds every printed total on the pages it reviews, from the rows of each page’s own table, whether or not the batch changed the total.
28 August 2026 — three claims corrected on our fault-code pages: (a) MG P0087. The page told readers that premature low-pressure fuel-pump failures on the older MG3 appear in the Australian used-car assessments, and linked our MG3 problems page as the evidence. No such pattern exists in that research: it records five owner patterns, none of them a fuel pump, and the only fuel item on the linked page is the 2021 fuel-tank strap recall — a tank-retention fault, not a fuel-supply one. The claim is withdrawn and the page now states the absence instead. (b) Chery P0300. Stale fuel and infrequent engine cycles on plug-in models were described as “documented hybrid-family behaviours”. We hold no Chery record on either; they are now named as general plug-in traits, with the gap stated. (c) BYD P0A80. The Sealion 7’s Power Limited pattern was called “well-documented” when it rests on a single source, and an English sentence appeared in quotation marks that was our own translation of our own research note — not an external quotation. The strength is now stated as single-source and the false quotation removed. All three were found by our own data-currency audit, not by a reader.
27 August 2026 — MG HS fluids, two corrections: (a) Second-generation cooling circuits. The note explaining which figures we were withholding said the extra cooling circuits belonged to the hybrid variants, with what it called the traction battery “on the PHEV”. Both attributions were reversed. The manual prints the power-battery coolant capacity against the column it heads 1.5T - HEV, and prints the water-cooled intercooler capacity against the DCT and manual columns — not against the hybrid columns. The rows are now published under the column headings the manual itself uses, and the two capacities it leaves blank are named as blanks rather than guessed. (b) First-generation brake fluid, refrigerant and engine coolant. The same page gave brake fluid as 1.0 L, A/C refrigerant as 560±20 g and engine coolant as 5.8 L under a heading reading “first generation”, while counting the PHEV as first generation elsewhere on the page. The first-generation PHEV manual prints 0.8 L, 750±20 g and 5 L. The three PHEV figures now sit beside the non-PHEV figures that had been standing in for them — brake fluid and refrigerant as two columns of the fluids table, the coolant as two rows of the coolant table above it. The three PHEV figures come from one document, the first-generation PHEV manual, and it reached our archive on 27 August 2026: the figures were right against the documents we held when we wrote them and wrong against the documents we hold now, which is why a growing archive sends a page back for re-checking and not only a reader’s email. Neither correction came from a reader. Both errors had been live on the fluids page before we caught them: the first by reading the rendered printed pages instead of trusting our text extraction, the second by our own gates, starting with the language gate.
22 August 2026 — GWM Ora recall coverage: our GWM recalls tracker stated the Ora had “zero Australian recalls to date”. That was wrong: recall REC-005843 (December 2023, 1,659 cars) covers a charging-safety software fault — unplugging the cable without cancelling the charge can draw an electrical arc. The recall predates our tracker’s launch and was missed in the original registry sweep; a re-verification pass found it. The tracker and the Ora guidance now include it, and our weekly recall check has been widened to sweep the full official registry listing — not just per-model searches — so an omission of this kind is caught structurally, not by luck.
21 August 2026 — BYD service-schedule totals: five BYD schedule pages briefly showed hand-typed multi-service totals that disagreed with the sum of the listed prices (largest error: $1,000 on the Sealion 7). Our programmatic verification caught the mismatch within minutes of publication; all five totals now equal the sum of the rows shown. The per-service prices themselves were correct throughout.
20 August 2026 — Chery Tiggo 7 generations (Australia): our Tiggo 7 hub initially described the current Australian petrol range as “1.6T DCT (2WD & AWD)”, following the naming on Chery’s official service-pricing page. Government Green Vehicle Guide data shows two generations sold side by side: the Tiggo 7 Pro 1.6T (2023–2025, 95 RON) and the new Tiggo 7 1.5T (2025-on, 91 RON). The hub now presents both, including the fuel-grade difference. Corrected same day.
