The Q8 e-tron is the facelifted successor to Audi's original e-tron, built on the same MLB evo platform at the Brussels plant until production ended in February 2025. The 50 quattro uses dual asynchronous motors producing 250 kW (340 hp) with a 95 kWh battery (89 kWh usable), delivering around 350-400 km of real-world range. It shares core hardware with the earlier e-tron 55 but benefits from a larger usable battery, improved efficiency, and Samsung SDI cells rather than the recall-affected LG modules. Air suspension is standard, as is Audi's dual-touchscreen MMI system.· more· less

Rotor shaft seal deteriorates, allowing coolant into the motor housing and requiring full motor replacement · more· less
The most serious known issue carried over from the earlier e-tron. The rotor shaft seal separating the coolant circuit from the motor's electrical components can fail, allowing coolant to seep into the motor housing and destroy the windings. Once coolant enters the motor, the entire unit must be replaced as the seal cannot be serviced independently. On pre-facelift e-trons, this affected approximately 2% of cars, particularly 2019-2021 builds. The Q8 e-tron benefits from later production and potentially improved seal materials, with fewer reported cases so far, though the fundamental design is the same. Audi extended the motor warranty to 10 years / 190,000 km in the USA, but this extension does not apply to European-market vehicles, which retain only the standard 2-year warranty. During inspection, check the small plastic catch reservoir next to each motor: it should be empty. Any coolant present indicates an active leak.
Air suspension compressor or strut leak
€1,000 - 2,5002 of 6
Air compressor fails or air springs develop leaks, causing ride height faults and uneven stance · more· less
All Q8 e-tron models come with adaptive air suspension as standard. The compressor can fail, causing the car to sag on all corners with a suspension malfunction warning. Individual air struts can also develop leaks, particularly after extended parking in cold or damp conditions, causing one corner to sag overnight. The Q8 e-tron received an updated compressor design and revised control unit software (August 2023) compared to pre-July 2019 e-tron builds, which reduces but does not eliminate the risk. Compressor replacement costs approximately €950-1,200, while a single air strut runs €1,200-1,800. The system shares components with the Audi Q7 and Volkswagen Touareg, so parts availability is good.
12V auxiliary battery drain
€200 - 5003 of 6
12V battery drains flat within 1-2 weeks if the car is not driven or plugged in · more· less
A common issue across the e-tron range and many other EVs. The 12V battery powers all ancillary systems and can drain within 7-14 days if the car is not driven or plugged in. The DC-DC converter that charges the 12V from the HV battery only operates when the car is in Ready mode or during HV charging. The myAudi app regularly polling the vehicle accelerates drain. When the 12V dies, the car becomes completely unresponsive despite a fully charged main battery, often requiring towing or a portable booster. Replacement costs €200-350 plus potential towing charges. Keeping the car plugged in or using a trickle charger during extended parking prevents the issue. Audi released software updates on later production cars to reduce standby drain, and the Q8 e-tron benefits from these, but the fundamental issue remains if the car sits for more than two weeks.
MMI infotainment system freezing and crashes
€0 - 1,5004 of 6
Dual touchscreens freeze, go black, or become unresponsive, sometimes requiring dealer intervention · more· less
Owners report intermittent MMI freezing, delayed touchscreen responsiveness, Bluetooth connectivity drops, and complete system crashes requiring reboots. The system can display loading messages that persist indefinitely. A quick fix is holding the power/volume knob until both screens turn off. For persistent issues, locking the car and walking away with all keys for one hour forces a full system reboot. Audi has released multiple software updates, including the 3812 update which improved CarPlay stability. Some dealers report that large updates can take a full day, and occasionally require replacement of the MMI control unit (€800-1,500). The Q8 e-tron received software stability improvements over the earlier e-tron, but reports persist on 2023-2024 builds. Ensuring all updates are applied before purchase is important.
DC fast charging handshake failures
€0 - 8005 of 6
Car fails to initiate DC charging sessions at public CCS stations, timing out during handshake · more· less
Some Q8 e-tron owners report the car repeatedly failing to start DC fast charging sessions at public stations. The car attempts to handshake with the charger but times out before energy flows. This is often software-related rather than a hardware defect: Plug and Charge configuration issues, outdated vehicle software, or specific charger incompatibilities are common causes. Trying a different charger brand, disabling Plug and Charge, or using an RFID card instead of the app often resolves the issue. In rare cases, the charge port lock actuator or onboard charger requires replacement (€400-800). AC home charging typically works without issues. Software updates have improved charger compatibility on later builds.
Premature brake pad and disc wear
€400 - 9006 of 6
Heavy vehicle weight combined with blended braking can cause faster-than-expected pad and rotor wear · more· less
The Q8 e-tron weighs approximately 2,520 kg, and despite regenerative braking, some owners report needing brake pad and rotor replacements earlier than expected, with vibration or pulsing pedal returning even after replacement. The blended braking system varies the mix of regenerative and friction braking depending on battery temperature and state of charge, which can increase friction brake use in cold weather or when the battery is nearly full. This is particularly noticeable on cars driven primarily in stop-start urban traffic without adjusting the regenerative braking intensity. A full brake job (pads and discs, front and rear) runs €800-1,400 at an Audi dealer, though some of this falls under normal wear. The issue is partly addressed by keeping regenerative braking at maximum and avoiding unnecessary brake pedal use.
Improved over the earlier e-tron, but motor seal risk remains
The Q8 e-tron 50 benefits from later production compared to the original e-tron: Samsung SDI batteries (no LG recall), an updated air suspension compressor, and improved software. Battery degradation data from the e-tron platform is encouraging, with many cars showing only 5-7% capacity loss at 50,000-80,000 km. The motor coolant seal remains the most significant concern. While incidence appears lower on later builds, the fundamental design is unchanged and European buyers lack the 10-year motor warranty extension that US owners received. Air suspension and 12V battery drain are manageable with proper maintenance. Budget for the motor risk and verify all recall work before buying.
Service history
Complete Audi dealer or authorized EV specialist records. Verify all software updates have been applied and service performed every 30,000 km / 2 years.
Tires
Check tread depth, age (date codes), and uneven wear. The Q8 e-tron weighs over 2,500 kg and wears tires faster than combustion SUVs. Budget for replacement every 30,000-40,000 km.
Body condition
Inspect for parking damage and wheel curb rash. The 19-inch and larger wheels are expensive to repair or replace.
Test drive (minimum 30 minutes)
Include both urban and highway driving. Test all driving modes, regenerative braking settings, and climate controls.
Specific for this vehicle
Inspect motor coolant catch reservoirs
Locate the small plastic catch reservoir next to each motor. Both should be completely empty. Any coolant present indicates an active seal leak requiring motor replacement.
Check air suspension operation
Cycle through all ride height settings. Listen for compressor noise. All four corners should sit level when parked on flat ground. Warning messages indicate compressor or strut issues.
Test AC and DC charging before purchase
Plug in to both AC and DC chargers and confirm charging starts and progresses normally. DC charging should reach up to 150 kW. Check for any charging errors or handshake failures.
+ 4 more checksShow less
Check 12V battery voltage and age
Via MMI or with a multimeter, check 12V battery voltage. Should read 12.4V or above with the car off. Ask when it was last replaced.
Test MMI system thoroughly
Use both touchscreens extensively. Test Bluetooth, navigation, Apple CarPlay/Android Auto, and climate controls for any freezing or lag. Verify the software version is current.
Check battery state of health
Request a battery health report or use an OBD tool (e.g., VCDS or OBDeleven). At 100,000 km, expect 88-94% state of health. Below 85% at this mileage warrants investigation.
Inspect brakes for vibration and wear
During test drive, brake firmly from highway speed. Any vibration or pulsing indicates disc warping. Check pad thickness visually through the wheel spokes.

The brake pedal recall is the most critical safety item: the pushrod screw connecting the brake pedal to the booster can detach, resulting in loss of braking. This recall affects 96,000+ vehicles globally and owner notifications were sent in April 2026. Verify completion with an Audi dealer using the VIN. The brake pressure line recall applies specifically to 2024 models built between May 2023 and March 2024.
Warranty Status
Factory warranty (2 years, no km limit)Expired or expiring on most used Q8 e-trons
HV battery warranty (8 years / 160,000 km)Covers capacity below 70%. Check remaining coverage by VIN.
Motor warranty (EU)Standard 2 years only. No EU extension (US got 10 years / 190,000 km).
Rust perforation warranty (12 years)Active on all Q8 e-trons, valid until at least 2035
Most used Q8 e-trons are at or approaching the end of the standard 2-year factory warranty. The HV battery retains 8-year / 160,000 km coverage against falling below 70% capacity. Audi extended the electric motor warranty to 10 years in the USA, but this does not apply to European-market vehicles. Some owners have obtained goodwill motor repairs in Europe, but this is discretionary. Consider third-party EV warranty coverage if purchasing outside the factory warranty period.
