2024 Audi Q4 e-tron Powertrain & Transmission Problems

My Audi Q4 Etron has had this issue since it was new. The car has a sensor as part of the drivers seat. Once you sit in the seat the car turn on and you can start driving. The problem is if you make any movements, like turn to look back while your backing the car up or you reach over to pick up something off the passenger front seat the car will abruptly stop and turn off. It can take up to two minutes for the car to start again, twice i was left in the middle of a four lane intersection stranded. The second time it nearly caused an accident as multiple cares slammed their brakes. The dealership said that its a common complaint but there in nothing they can do, i was told to stay seated and to not move while driving. My wife also got stranded blocking an intersection and it also almost caused an accident, she was so scared that she will not drive the car or ride in it when im driving. Audi need to fix this before someone gets killed. I hope you can help.

I am filing this complaint due to ongoing electronic and drivetrain malfunctions that may impact safe vehicle operation. AWD System Malfunction (Primary Safety Concern) The vehicle repeatedly displays four-wheel drive system malfunction warnings. I have brought the vehicle to the dealership three times for this same issue. The malfunction continues unresolved, raising concerns about traction, stability, and drivetrain reliability. Intermittent Entry Failure Biometric entry intermittently fails, forcing use of the key fob. This could delay access in emergency situations. Remote System Failures Remote vehicle functions (lock/unlock and climate control) operate inconsistently or fail entirely, often generating error messages. Audi has stated this is a system infrastructure issue with no current fix. Battery Power Inconsistency Although the battery indicates 100% charge, actual available power never reaches full output and drops shortly after driving. This creates uncertainty about vehicle performance and usable range. HUD Feature Does Not Perform as Advertised The head-up display does not show surrounding vehicle speeds as advertised, only colored indicators. This removes expected situational awareness information. Summary The vehicle exhibits repeated drivetrain warnings, electronic access failures, and inconsistent battery performance. These issues persist despite multiple service visits. I am requesting this complaint be formally recorded and investigated due to potential safety implications.

I purchased a new 2024 Audi Q4 e-tron. The first malfunction occurred in January 2025 when a dashboard warning appeared stating the vehicle was “unable to read traffic or road signs.” The dealer confirmed a front-camera sensor failure and replaced the camera under Repair Order #193312 (1/17/25 – 1/29/25) at approximately 397 miles. In February 2025, the vehicle displayed repeated “drive system malfunction” warnings and would not start reliably. The dealer determined the issue was linked to the 12-volt battery and replaced it under RO #194457 (2/24/25 – 3/14/25, 866 miles). Soon after, persistent drive-system and electrical faults continued (RO #195096 and #195241 from 3/17 – 3/27 at 866–1,081 miles) but no repair was completed. On 4/10/25, an “AWD malfunction” occurred, and the vehicle was towed. Under RO #195846 (4/10/25 – 4/25/25, 1,594 miles), the front electric motor/drive unit was replaced. The vehicle remained out of service for extended periods. I was provided an EV loaner during the initial repair in January and gasoline loaner vehicles thereafter. In June 2025 (RO #198283 at 3,161 miles), a factory recall for the onboard charger was performed. The warning “Pedestrians cannot hear motor sound” appeared both before and after the motor replacement, suggesting a persistent fault in the Acoustic Vehicle Alerting System (AVAS). These repeated electrical, sensor, and propulsion failures — all within 3,000 miles of use — raise concerns about the reliability and safety of the ADAS camera, drive unit, and pedestrian-alert system. Power loss and a nonfunctional pedestrian-warning feature could increase risk to the driver and others. The manufacturer has been notified, and both dealer and manufacturer-updated repair records — showing mileage inconsistencies between versions — are available for review upon request.
