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 and compromises the gearbox oil, causing mechanical failure. The current dealership has taken a fluid sample but refuses to share the results, denying a high-voltage drivetrain warranty submission and…

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 secondary "click" sound is heard and felt through the controls. This condition did not exist when the vehicle was new and has progressively worsened in frequency and volume. The symptoms suggest a binding…

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.

A vehicle was taken to a collision repair facility following minor front-end damage. At intake, the repair facility documented visible exterior damage but did not perform or document an underbody inspection, which is necessary to assess high-voltage battery integrity in electric vehicles. After the vehicle entered teardown, the repair facility later claimed that the high-voltage battery was damaged and recommended that the vehicle be declared a total loss. This determination was made without documented evidence of required OEM diagnostic procedures and without initial intake documentation supporting battery damage. The sequence and timing of documentation raises concern that the battery…

After dealership service and recall-related calibration work, my vehicle developed multiple safety-related issues that did not exist prior to service. The dealership documented a diagnostic trouble code for âHybrid/EV Battery Thermal Runaway Detectedâ (P29FF00), a critical high-voltage battery safety fault. Instead of diagnosing and repairing the root cause, the dealership cleared the fault code and returned the vehicle to me, stating it was operating as designed. Following this, the vehicle has exhibited abnormal and unsafe behavior, including significant and inconsistent loss of driving range, irregular energy consumption, regenerative braking issues, and braking concerns such as…

I own a 2022 Audi e-tron Sportback that experienced multiple serious issues involving the high-voltage battery system. During service at Audi South Atlanta, the dealership documented diagnostic trouble code P29FF00 â Hybrid/EV Battery Thermal Runaway Detected. This code is related to battery overheating and potential thermal runaway, which is a critical safety condition in electric vehicles. Despite identifying this safety-related fault, the dealership did not perform any repair or replace any components. Instead, they cleared the fault codes and returned the vehicle to me stating it is operating as designed. Prior to and during this issue, the vehicle experienced: â¢Severe range…

The AEB system engages periodically with any obstacles while at a high speed. Suffered whiplash and anxiety as problems occurs without warning. Vehicle is available for inspection. Unprovoked Braking at high speeds on highway can be dangerous. Dealer has not responded to complaints of the issue on 2-3 service appointments. Dealer states there are no codes and no follow up was given. No previous errors notes vehicle was bought new and we are first owners.
