AUDI Complaints

While my vehicle was in for the Audi piston issue, they stated my water pump needed to be replaced and isn’t covered by a recall (yet). My vehicle had less than 42,000 mile on it. I was lead to believe that this problem is coming up more often and they believe a class action lawsuit will come about. I needed to pay over $1,700 out of pocket and was told I was saving so much money because they already had the engine apart because of the piston recall. This is unacceptable.

The vehicle exhibits multiple, unresolved safety-critical defects across software and mechanical systems that create an unpredictable and dangerous driving environment. Despite multiple repair attempts, the manufacturer has failed to certify the vehicle as safe for operation. 1. Critical ADAS Failures (Forward Collision/Lane Keeping): Automatic Emergency Braking (Pre-Sense): The vehicle suffers from unprompted alerts and phantom braking incidents, creating an immediate risk of rear-end collisions. Lane Keeping Assistance: The system has experienced unexpected steering pull, which could lead to an unprompted lane departure. Adaptive Cruise Control (ACC): The system consistently fails to detect lead vehicles in 40% to 50% of instances. The most recent failure was documented via timestamped screenshot on May 12, 2026, around 4:07 PM PT. This defect is reproducible and renders the automated safety suite unreliable. 2. Powertrain & Mechanical Defects: Pneumatic Air Leaks: The vehicle exhibits 100% pneumatic air leaks during acceleration. The service center has dismissively characterized a total pneumatic system failure as "normal," which I find technically unacceptable and a sign of neglected mechanical integrity. 3. Electrical & Starting System: Recurring Ignition Failures: The vehicle has experienced multiple failures to start, most recently leaving my child and me stranded for 10 minutes. Safety & Use Impairment: These intermittent failures compromise the vehicle's utility and the safety of my family. Incident History: The first time this occurred, I called Audi Roadside Assistance, but the engine started approximately 30 minutes later; as a result, I do not call roadside assistance now when it happens and instead attempt to restart it repeatedly. Current Status: I am forced to drive the car in a constant dilemma, knowing it might fail at any time and leave me stranded.

2019 Audi q5 drive system malfunction/start stop malfunction. Error code will come on randomly in traffic and when you try to put your foot on the gas it hesitates and you need to push harder on the gas. Car will also lose acceleration power and take longer to reach desired speed. Drive system malfunction light will come on as well as an error stating start/stop system malfunction. Have had multiple sensors and battery replaced with only temporary results. Start stop malfunction will come on randomly at any time and then go away for a certain amount of time and come back again. This malfunction is constantly going on and off and is sometimes dangerous because you don’t know when it will happen, if it does happen you don’t know if you need to press harder on the gas, or if you do accelerate you don’t know if you’re damaging your engine. After multiple fixes at Audi dealership and other repair shops, them attempting to address this issue has done nothing for the car leaving me to believe this could be a fault. This issue has been going on for at least 10 months with multiple dealer visits attempting to address this issue.

The contact stated that the contact's wife had spilled a liquid substance into the vehicle. In addition, the contact was provided pictures of the corrosion. The contact referenced an unknown recall which had a similar failure description, however the contact's VIN was not associated. The dealer was made aware of the failure. The contact was informed that the repair was not covered under the recall. In addition, the contact was informed that the unknown recall only covered the seal. The contact was informed that the recall did not cover the replacement of the gateway control modular. The manufacturer was made aware of the failure and a case was filed. The contact was informed that the repair of the corroded seal was covered under the recall. The contact was advised to take the vehicle to the dealer for diagnostic testing. The failure mileage was approximately 103,000. VIN was unavailable.

All of my display screens went blank at 108 miles. I had no speedometer, no fuel level gauge, no warning indicators, and no audio alerts including turn signals. The vehicle was towed to the dealership since it was a safety issue for me to drive. It has been there since November 2025.

As per the Audi dealership inspection: Driver's-side rear coil spring is broken (also noted that the passenger-side spring is "swollen" and will need to be replaced). Appears to be a known issue; many complaints can be found online for the exact same issue (google 2017 Audi Q7 rear broken spring). The NHTSA issued a recall for a similar issue within the VW/Audi group for the VW Atlas (a similar vehicle in the Audi/VW motor group).

On three occasions, while in regenerative braking mode, my car failed to engage the brakes at low speeds. After pressing on the brake pedal for several seconds with no response, the wheels then locked completely - but only after the car had traveled had traveled around 30 feet. The dealer has inspected the car and has not been able to replicate the problem, so they say there is nothing they can do to correct it (although they are NOT saying that they don't believe me). There were no warning lights or messages about a failed system - the brakes just didn't work. This was very unnerving to me, and I don't see how I can drive the car without some corrective measures taken. I was fortunate that these incidents happened where no person or other car was nearby, but that was only luck. I reported the three incidents to the dealer, and brought the car in twice for them to inspect the car.
