Audi e-tron (GE) and Q8 e-tron: dos motores asíncronos and baterías de 71 a 114 kWhFire risk
Battery cell modules with a risk of overheating and fire on the Audi e-tron / Q8 e-tron
Why this rating?
Critical severity: It can destroy the engine or gearbox, or affects safety.
Frequency occasional: A precautionary recall with a definitive solution (diagnosis and replacement of modules). The KBA has no record of accidents or injuries, so although it covers tens of thousands of cars, it is rated 'occasional'.[1][2]
Symptoms
- Audi states that a loss of range or power can be an early sign of the problem.[2]Reduced electric range: other faults that cause it · Monitor
Why it happens
Technical deviations in the charging and discharging behaviour of specific cell modules in the high-voltage battery, which can lead to thermal overload. According to the US safety agency NHTSA, cited by auto motor und sport, the modules are made by LG Energy Solution.[1][2]
If it is not repaired: Overheating, smoke or, in the worst case, a vehicle fire. Until the inspection is carried out, Audi recommends not charging above 80%, a limit that is set in the MMI or the My Audi app.[1][2]
Affected cars and years
e-tron and e-tron Sportback built from 16 March 2018 to 11 March 2022 (Audi codes 93U9 and 93V2, Safety Gate A12/00407/24, KBA 013462). Not all cars from the period are affected: only the chassis number confirms it.[1][2]

More faults with a fire risk on other engines and cars
- Critical severityFrequency: Very frequentBMW B47EGR cooler leaks with risk of engine fireYes: the EGR valve cooler can suffer internal coolant leaks which, mixed with soot and oil, can reach combustion temperatures; BMW has launched several technical campaigns since 2018 to inspect and replace it because of the risk of engine fire.Repair (garage): €500–€1,500
- Critical severityFrequency: Very frequentBMW N57EGR cooler leaks with risk of engine fireYes: like the N47 and B47, the N57 is covered by BMW's service campaign for EGR cooler leaks, which can mix coolant with soot and oil to combustion temperatures. BMW checks free of charge the 6-cylinder engines built between July 2012 and June 2015 because of the fire risk.
- Critical severityFrequency: Common1.6 EcoBoostCracked cylinder head from overheating, with fire riskYes: Ford acknowledges that a loss of coolant circulation can overheat the engine, crack the cylinder head and let oil escape onto hot areas, with a risk of fire. It has issued recalls in South Africa (2017-2018) and in the US/Canada (2013 and 2017); we have not found an identical campaign in Spain.
- Critical severityFrequency: Very frequentHyundai Tucson IIIFire risk from the ABS control module (HECU)Yes. Hyundai recalled the Tucson TL built between February 2017 and August 2020 (campaign 11DC03) because the ABS module can fail internally and cause a short circuit with a risk of fire in the engine bay, even with the car parked. In the US the same campaign (20V543000) covered model years 2016-2021.
- Critical severityFrequency: Very frequentKia Sportage IVShort circuit in the ABS/ESP unit with fire riskYes: Germany's KBA and the US NHTSA have recorded several campaigns (2021 and 2025) over a short circuit in the ABS/ESP unit that can cause a fire in the engine bay, even with the car parked and switched off.
- Critical severityFrequency: Very frequentKia Sportage IVFaulty connector in the electric auxiliary heater with fire riskYes: in August 2022 the KBA recorded a campaign over a faulty connector in the electric auxiliary heater of some Sportage QL cars, with a fire risk.
