Jaecoo 7 warning lights coming on with no fault found
Owners report warning lights or error messages appearing on the instrument panel, sometimes a whole string at once, that later clear by themselves, after a restart or after the battery is disconnected; dealers often find nothing. No single cause has been confirmed, and some cases, such as brake-system warnings, need checking every time.

What owners report
- A UK owner of a 2025 car says random warning lights keep appearing on the instrument panel. [9]
- An Australian plug-in hybrid owner got a 'do not drive' warning at about 1,085 km; the dealer had the car towed in, with an inspection 16 days away. [10]
- On a 1.6 Tiggo 7 Pro Max, a string of error messages started appearing at about 10,000 km. [3]
- After a start at −25 °C every warning icon on a Tiggo 7 Pro Max lit up at once; switching off and restarting cleared them. [1]
- An Omoda C5 showed a brake-system fault warning that went out after ten minutes; the dealer found nothing. [5]
Evidence comes from: Chery Tiggo 7 Pro Max (4), Chery Tiggo 7 Pro (1), Omoda C5 (2), Jaecoo J7 (Russia) (1), Jaecoo 7 (UK and Australian owners) (2). Reports come from Jaecoo 7 owners in the UK and Australia, a Russian Jaecoo J7 owner and owners of sister Chery and Omoda models. The warnings differ from car to car, so this page groups a pattern, not one fault.
Several Russian reports followed starts in hard frost (one at −25 °C); UK winters rarely reach that, but the UK and Australian reports were not cold-related.

What to ask your dealer
- “Please read the stored fault codes and give me a printout, even if the light has gone out.”
- “Is there a software update for the instrument cluster or body control unit that addresses false warnings?”
- “Could this be covered by recall R/2026/299 (driver's seat wiring), whose effects include warning lights?”
- “If no fault is stored, will you note my complaint on the job sheet so it is on record under warranty?”
Is it safe to keep driving?
Do not assume a warning is false. A red brake-system, oil-pressure or coolant-temperature warning means stop safely and call a dealer, as the owner's manual says. One Omoda C5 owner reports the car stopping dead from electronic errors. If a warning clears, still have the stored codes read.
Questions
- Why do warning lights come on and then go off on my Jaecoo 7?
- Owners report it after cold starts, after a flat battery and with no clear trigger. No cause has been confirmed. Recall R/2026/299 lists warning lights among the effects of a wrongly routed driver's seat harness, so check your car against it.
