What 8 owners told NHTSA about the 2024 Audi A5 Coupe

The contact owns a 2024 Audi A5. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power with an unknown warning light illuminated. The vehicle was towed to the dealer, and the parking brake actuator was replaced; however, the failure persisted. Additionally, the brake pedal was loose while depressed. The vehicle was towed back to the dealer, where the parking lock solenoid (N486) was replaced; however, the dealer was unable to duplicate the loose brake pedal failure. No additional repair was performed. The contact stated that the failure reoccurred. The vehicle was towed to the dealer a third time and the Selector Lever Sensor System Control Module (J587) was replaced. The contact stated that the vehicle had not been driven since the third repair, and that the contact was fearful of driving the vehicle. The manufacturer was made aware of the failure, and the case went to arbitration. The manufacturer's lawyer informed the contact that the failure was due to normal transmission wear and tear. The failure mileage was 22,916.

I am reporting a severe, systemic, and undiagnosed electrical defect that compromises vehicle safety and control. The manufacturer’s authorized repair facilities and corporate Technical Assistance Center (TAC) have explicitly documented that their factory test plans are "inconclusive" and they cannot isolate the root cause of the failures. The primary symptom is the catastrophic failure of the climate control/defrost system, which intermittently stops cooling and blows hot/ambient air. Dealerships have repeatedly replaced the physical AC head unit (E87), replaced high-pressure switches, and performed battery capacity discharges to clear persistent diagnostic trouble codes (DTC B131207 and B10AE22). Because these hardware replacements fail to fix the issue and the system continues to drop out, the defect lies deeper within the vehicle's central electrical architecture or wiring harness. Additionally, the vehicle has exhibited erratic, un-commanded behavior. After parking, turning off the vehicle, and walking away, the vehicle spontaneously started running on its own without any input. The dealership was unable to find stored codes for this event, indicating the vehicle’s diagnostic system is failing to log critical electrical malfunctions.A vehicle that spontaneously starts itself poses an extreme risk of carbon monoxide poisoning in residential garages, as well as a runaway or theft hazard if a deeper electrical short commands the transmission to engage while unattended.The manufacturer has exhausted its standard Technical Service Bulletins (TSB 2078655/3) and multiple corporate TAC cases (#3667725 and #3686882), ultimately releasing the car back to me each time. I am at a loss for what to do because this car is dangerous, they don't know what is wrong with it, and I am being forced to drive it.

The contact owns a 2024 Audi A5. The contact stated that while the vehicle was parked, and started, the vehicle unexpectedly surged forward. The contact stated that occasionally the vehicle started independently without driver input. Additionally, the air condition was blowing warm air instead of cold air. The dealer was notified of the failure; however, the vehicle was not diagnosed or repaired. The manufacturer was notified of the failures. The approximate failure mileage was 16,581.

Audi’s wireless charging pad in 2021–2024 A4/A5/Q5 models: •Overheats the phone •Triggers a thermal radio throttle •iPhone temporarily disables Bluetooth hardware •Audi MMI sees that and throws: “Bluetooth function is currently unavailable.” •Wireless CarPlay collapses because it needs Bluetooth + WiFi Direct •Audio goes dead along with it This EXACT sequence is documented across A4/A5/Q3/Q5 forums and Audi service bulletins. The pad is the culprit — not your phone, not the car. When bluetooth and apple car play shut down, so do directions which causes driver to scramble to find phone and follow phone screen which distracts drivers and causes accidents. It happens every time you use the tray after 5-20 minutes. Very scary for older drivers. Would like NHTSA to pressure Audi into a recall and fix the pad at Audi's expense. I bought the car to use the wireless charger, not have to work around it. And it is exceptionally unsafe.

Steering malfunction indicator light illuminated and I experienced a total loss of power steering. Brought car to Dealer Service Center. Was informed that the problem is related to a known software issue and that an update to the software is expected sometime toward the end of Q4 2024. In the interim, DTC's have been set to passive and the steering malfunction indicator light has been deactivated.

I was driving up a clear road, heard and exploding sound and witnessed my drivers side window shatter. The glass that was not protected by tint, I could hear crumbling into the frame. I could not see out of my window and thankfully did not swerve due to scare of the explosion sound.Upon looking online, others have experienced this with Audis. There were no warnings present. Vehicle has not been inspected or repaired yet. Nothing was noted in the road, no marks on vehicles.

After fueling, MPG was 370 and dropped to 325 within one minute. Same night, vehicle began to jerk back and forth and cluster stated "Drive system: malfunction! Please contact Service." Took to dealership next morning and service stated fuel pump codes popped up. The vehicle is just leased and only has 1,000 miles.
