Audi e-tron e-tron / Q8 e-tron 50 and 55 hp problems
The Audi e-tron used the e-tron / Q8 e-tron from 2019 to 2025 (e-tron 50 quattro, e-tron 55 quattro and e-tron S). 2 documented faults affect it; the most important is “battery cell modules with a risk of overheating and fire” (critical severity, occasional). Our verdict depends on the version: “Buy” for Q8 e-tron 50 / 55 and SQ8, 95 and 114 kWh gross batteries (2022-2025); “With caution” for e-tron 55 quattro and S, 95 kWh gross battery (2019-2022) and e-tron 50 quattro, 71 kWh gross battery (2020-2022).

Verdict for the versions it uses
e-tron 55 quattro and S, 95 kWh gross battery (2019-2022)2019–2022 · 408–503 hp
With cautionThis is the version with both battery recalls: the 2019 one on the first units (moisture at the connection) and the 2024 one on the cell modules. Ask for proof of both and a battery health report.[4][5][6]
e-tron 50 quattro, 71 kWh gross battery (2020-2022)2020–2022 · 313 hp
With cautionIt falls within the production period of recalls 93U9/93V2 (March 2018 to March 2022): check by chassis number whether the battery was inspected. Audi guarantees a minimum battery health of 78% at 3 years or 60,000 km.[2][4][5]
Q8 e-tron 50 / 55 and SQ8, 95 and 114 kWh gross batteries (2022-2025)2022–2025 · 249–503 hp
BuyOpen sources record no battery, motor or power electronics faults for this version, and it falls outside the production period of the module recall (up to March 2022). There is little long-term usage data.[1][4][5]
Faults that affect the e-tron
- Critical severityFrequency: OccasionalTraction batteryBattery cell modules with a risk of overheating and fireYes: in February 2024 Audi recalled 42,668 e-trons and e-tron Sportbacks built between March 2018 and March 2022 (1,453 in Germany) because voltage loss in some cell modules can cause thermal overload and fire.
- Critical severityFrequency: OccasionalTraction batteryMoisture ingress at the battery connection on the early units (2019)Yes, on the early units: in June 2019 Audi recalled 1,644 e-trons worldwide because moisture could enter the battery connection and cause a short circuit, overheating and, in the worst case, fire.

Critical severityFaults of the Audi e-tron outside the engine
Suspension, brakes, electronics and the rest of the car: they occur with any engine.
- Critical severityFrequency: OccasionalBrakesElectromechanical brake booster failure and corrosion of the brake pressure unit (ABS/ESC)In 2021 Audi recalled two batches of the e-tron because of the electromechanical brake booster (2,303 cars, recall 47R1) and the corrosion of the brake pressure unit (361, recall 47R7). Both can affect the brake booster, the ABS and the ESC and lengthen the braking distance.
- Critical severityFrequency: OccasionalBrakesBolt on the rod between the brake pedal and the brake booster that can work looseAudi first recalled a small batch of 2019 e-trons (recall 46P6) and, in 2026, about 96,000 e-trons and Q8 e-trons worldwide because of the bolted connection of the rod between the brake pedal and the brake booster, which can work loose. It is checked and tightened free of charge.
- Critical severityFrequency: OccasionalBrakesOvertightened bolts on the brake hoses of the Q8 e-tron (2023-2024)In 2024 Audi recalled 284 Q8 e-trons and Q8 e-tron Sportbacks built between May 2023 and March 2024 because overtightened bolts on the brake hoses can break, causing a brake fluid leak and the failure of one circuit.
- Critical severityFrequency: OccasionalSuspensionCorrosion of the rear axle arm eccentric bolt nutsAudi recalled several models, including the e-tron, built between 7 November 2019 and 16 April 2021 because the nuts on the rear axle arm's eccentric bolt can break through stress corrosion, with a risk of accident.
- High severityFrequency: OccasionalSuspensionUneven rear tyre wear caused by changes in the rear axle toe and camberAudi recalled the e-tron built from November 2019 to April 2021 because the toe or camber of the rear axle can change and wear the rear tyres faster and unevenly. A tyre worn down to the carcass can suddenly lose pressure.
