How we count
Every number on a fault page comes from a dataset we build from public owner reviews and official sources. This page explains how, and what the numbers do and do not mean.
Where the reports come from
The Jaecoo 7 is new to the UK, so British owners have little history to go on. The same car is sold in Russia as the Jaecoo J7. It shares Chery's T1X platform with three models sold there in large numbers: the Chery Tiggo 7 Pro, the Tiggo 7 Pro Max and the Omoda C5. The Tiggo 7 Pro Max and Omoda C5 are also sold with the Jaecoo's 1.6-litre turbo petrol engine and seven-speed dual-clutch gearbox. Russian owners review these cars in detail on drom.ru, a large Russian car-owner review site. Its short reviews have a separate "breakages" field, which is close to a fault log.
On 12 November 2026 we read every review of those four models on drom.ru: 1,331 reviews (1,085 short reviews and 246 long reviews and follow-ups). We read only public pages, at one request every two seconds, and only pages the site's robots.txt allows. We did not use Drive2.ru, another large Russian site, because its robots.txt does not allow automated reading.
We also read public posts by Jaecoo 7 owners in the UK and Australia on owners' forums and review sites (8 owners, 21 faults so far). They count as owners of the Jaecoo 7 itself. Several large sites (Reddit, Honest John, Trustpilot) block automated reading, so this English sample is small and not representative.
UK sources are used beside them: the DVSA recall database, published reliability surveys and long-term tests by UK motoring titles. Each page lists its sources.
How a fault is counted
- Each review was read in Russian and every fault the owner described on their own car was recorded: the system, the symptom, the stated cause, what was done, whether it was under warranty, whether it was fixed, and the mileage if given. Hearsay about other people's cars, design dislikes, accident damage and routine servicing were left out, and so were drom.ru's translations of Chinese owners' reviews, because their authors cannot be counted. 358 reviews described at least one fault; 777 faults were recorded in all.
- Faults with the same symptom on the same system are grouped into one fault.
- We count owners, not posts: an owner who writes three times about the same fault counts once.
- Engine and gearbox faults are counted only from cars with the same 1.6 turbo engine or dual-clutch gearbox as the UK car. Faults of the 1.5 turbo with the CVT automatic, a combination not sold in the UK Jaecoo 7, are never used.
- Suspension, steering and brake faults are counted from all four models, because they are built on the same platform. We have not checked that every part number is the same, so a page where no Jaecoo J7 owner reported the fault says "platform-level evidence" and its title says "sister-car reports".
- Body, interior, electrics, infotainment and climate parts differ between the four bodies. For those, a fault needs at least two owners of the Jaecoo J7 itself before reports from the sister models are counted, or a UK source that confirms it.
When a fault gets a page
| Level | Condition | What we publish |
|---|---|---|
| Enough evidence | 5 or more different owners, or 2 or more owners plus an official or technical source | Its own page |
| Limited reports | 3–4 owners, or one technical source only | One line on the model page, marked "limited reports" |
| Not enough | 2 owners or fewer, nothing else | Nothing |
Official recalls are always published, whatever the number of owner reports.
What the numbers cannot tell you
- They are not failure rates. Owners with a problem are more likely to write about it. A fault reported by 20 owners out of 1,331 reviews does not mean 1.5% of cars have it.
- Most reports are from Russia. Winters of −25 °C, road salt and rough roads wear some parts faster. Pages flag faults that look climate-related.
- Sister cars are not identical. Where a report comes from a sister model, the page says which, and how many.
- Mileage is the owner's own figure when they gave one; many did not, so mileage charts use only the reports that did.
- Fixes are what owners say dealers did. Dealer practice in the UK may differ.
Updates and corrections
We re-read the sources every month and update counts, recalls and dates. A page's "last updated" date changes only when its data changes. To report an error, see contact; we correct confirmed errors within 72 hours.
