Audi e-tron Sportback

I was entering the freeway at a metered on-ramp. During my wait, the vehicle warned of objects that were close even though none were close to the vehicle. I then entered the freeway and several seconds later automatic emergency braking activated at a low speed of about 20-30 miles per hour with no car in front of me for about 100 ft, and the car that was there was not braking or slowing down. There was no apparent reason for the system to activate other than the already known fault documented…

- Vehicle was brought in operable condition to Audi service center for NHTSA recall numbers 25V900 and 26V240 on 06/18/26. - On 06/19/26, the Audi service center informed me after completing the 90TV software update (25V900) that every single light is on, on the dash and that they have to do a battery evaluation. - On 06/23/26, the Audi service center informed me a TAC ticket was created and they were waiting for a response. - On 06/30/26, the Audi service center informed me that they will have…

2021 Audi e-tron, 44,749 miles. Right after a scheduled service at Audi [XXX] on XXX, I noticed a loud droning/humming noise from the drivetrain while driving. The noise tracks with vehicle speed - it gets louder and higher-pitched as the car goes faster. I called the dealership to report it as soon as I got the car back in late XXX. Nobody responded. The noise is still present today, roughly five months later, at about 48,000 miles. The symptom matches Audi's own technical service bulletin…

While driving, the vehicle displayed three simultaneous warnings — “Drive system malfunction, safely stop vehicle,” “Electrical system malfunction, restart not possible, contact service,” and “All-wheel drive malfunction, limited stability” — and lost propulsion completely. This occurred on at least two separate occasions while driving. After each event, the vehicle would not restart for approximately 15 minutes, after which it began working again temporarily. The vehicle was taken to an…

The vehicle is experiencing an intermittent but active 'Electrical system: malfunction!' safety alert on the dashboard and myAudi app, caused by an internal high-voltage battery cell circuit fault (Diagnostic Trouble Code P0DB400 / U04A300) and a failure in the battery thermal runaway detection system. When the fault occurs, the vehicle suffers a complete loss of regenerative braking, severely affecting stopping predictability and vehicle handling. An authorized Audi dealership (Audi West…

I own a 2021 Audi e-tron with approximately 58000 miles. Beginning in March 2026, the vehicle developed intermittent Virtual Cockpit/instrument-cluster problems with blank display. I reported the condition to Audi dealer of Princeton NJ. The vehicle subsequently experienced two dead 12-volt battery incidents and became inoperable. The second 12 volt battery was new. Following the most recent incident, the Audi dealer diagnosed the Virtual Cockpit/instrument cluster as causing a drain on the…

The integrated high-voltage powertrain / single-speed transmission unit is failing, causing severe mechanical chattering, rapid actuator cycling, and vibration under the vehicle. This failure follows a recent catastrophic, unexplained total loss of traction/HVAC coolant while at a previous Audi dealership. Audi is aware of systemic coolant migration issues into the electric drive motors on 2022 e-tron models under Technical Service Bulletin (TSB) #2073858, where coolant breaches internal seals…

While driving my 2021 Audi e-tron Sportback Prestige, the high-voltage battery warning light illuminated on the dashboard. At the same time, regenerative braking stopped functioning, resulting in reduced energy recovery and a noticeable decrease in driving range. Before taking the vehicle to an Audi dealership, I had the diagnostic trouble codes read by an independent repair shop. The technician advised me to take the vehicle to Audi because the diagnostic information reportedly indicated a…

Component/System: Service Brakes, Hydraulic / Brake Pedal Assembly / Steering Linkage Description of Defect: A progressive mechanical noise and physical sensation occurs during driving transitions involving the brake, accelerator, and steering column. After the brake pedal is fully released and the accelerator is pressed, or when the steering wheel is turned, a distinct loud thunk and a sliding/dragging sound emanate from the brake pedal assembly area. When the accelerator is released, a…

Running 4430 MMI/MIB3 software (that was release almost 2 years ago) and now have stereo EQ settings that reset on their own, personalized favorites that delete on their own, and other personalization settings that reset on their own. Happens every 6-24 hours if settings are adjusted. Audi knows about it, refuses to allow dealers to update to newer software that will fix these since there are updated available that solves.
