2019 Audi Q5 problems

Filed Oct 25, 2026 · Brakes, Electrical · PA

In my daughter’s driveway with my foot on the brake, my vehicle suddenly accelerated forward without warning. I immediately pressed the brake pedal firmly and kept my foot on the brake, but the vehicle continued moving forward and would not stop. The vehicle crossed the street and entered the neighbor’s lawn heading towards a large tree. I managed to steer away from the tree and the neighboring house and return to the street. The vehicle then continued through a stop sign. I made a left to avoid another house and continued traveling one tenth of a mile before the vehicle finally came to a stop. Throughout the incident, my foot remained pressed on the brake pedal. Steering was very difficult. The engine did not sound as though it was revving loudly. The vehicle left deep marks in the grass, but I did not observe skid marks on the street. My initial report to AUDI I stated the vehicle was going 15-20 MPH however; I did a test with another vehicle and determined it was more like 25-30 MPH

The vehicle is experiencing an issue withe the All-Wheel Drive system where its function is affected by an issue Audi calls Shutter or Shudder. The degradation in this system's performance is characterized by drive system torque oscillations when the steering wheel is turned. A hazardous condition is introduced when the AWD system is required for traction control and the system either outputs oscillatory torque, or binds up at a time where smooth torque at each wheel is required to provide traction and directional control (e.g. snow and ice or rain conditions). Audi has stated that they do not consider this a safety issue. Audi is aware of the issue and has released a Technical Service Bulletin 39 24 60 2059057/8 April 3, 2024 entitled "Quattro Ultra Vibrations or Binding in Tight Turns." This TSB has multiple revisions and covers several of their models over several production years. The Audi prescribed procedure to address the issue is to verify the condition, then flush and fill the AWD system with a new, unique oil which is called out in the TSB. Unfortunately, this oil is not available and they are deferring repair of the affected vehicles. The condition appears to be related to wear/wear debris and the functional effects degrade with the accumulation of additional driving time.

Received a malfunction drive train alert on a 2019 Audi with approximately 66,000 miles at the time. Took it in to have it addressed and was advised it needed a new Turbo. The turbo has since been replaced. However, a vehicle with very low miles should not be having any drive train issues. There is a class action lawsuit against Audi for the same issue. However my vehicle was not included. This is a known issue with Audi.

Severe consequential safety defect involving total anti-lock braking system (ABS) failure stemming from a manufacturer recall defect and volatile CAN-bus network conditions during repair. This vehicle has less than 7,500 miles and has been grounded at an authorized dealership, Audi Brooklyn- Lic# [XXX], 700 Hicks Street, Brooklyn, NY 11231, for exactly 20 days since being flatbed-towed on [XXX], due to total power failure caused by the known manufacturing defect of clogged sunroof drains flooding the critical interior electrical network. The dealership replaced the comfort control module under the VIN recall warranty. However, during the dealer's active programming phase of this recall component, a fatal communication fault was introduced to the J104 ABS safety module. My original Service Advisor documented explicitly in writing via text that the technician observed the ABS faults materialize specifically during the recall programming process. No prior warning signs other than the vehicle's sudden loss of power. The manufacturer's design defect allowed moisture ingress to destabilize the vehicle's localized CAN-bus communication network, leading directly to the catastrophic failure of a critical braking system (ABS). Dealership management is now attempting to evade safety liability and force an out-of-pocket repair payment by manipulating records. They have actively backdated internal "Ready for Pickup" dates for the vehicle from August 24 to September 1 to hide an 8-day window where they concealed a New York State safety inspection failure from me and attempted to release an illegal, uninspected vehicle with compromised brakes back to a vulnerable consumer. The owners of the vehicle are [XXX]. Furthermore, despite claiming the ABS module was a severe safety hazard, the facility logged 50 unauthorized miles (odometer jumped from 7,437 to 7,487) on public roads while it has been in their custody.

2019 Audi Q5 had the hardware fail which controls the rear view camera (controls other functions too) It's known as the MMI and the replaced part says "MIB2 Main-Unit" on the housing. I have the old part that the dealer replaced in my possession. Dealer confirmed the part was broken and would require replacement. not having a rear camera impacts safety in parking lots, backing in to streets etc, as well as increased risk of backing off the road esp in tight settings. there was no initial warning - it 100% stopped working then would give some warnings or random short term use the past 3 months while scheduling replacement. Completely unreliable for day to day safety, as we back on to a busy road multiple times per day.

Went to Mavis on Weber Rd in Bolingbrook, IL for front brake replacement on June 6, 2026. It took 6.5 hours when I was originally told when I called to schedule the appointment it would only take 1.5 hours, so it was obvious that something was wrong. Within 100 yards of leaving their parking lot after the service appointment, an obvious clattering was present. I immediately called them to let them know the replacement had not been performed correctly. Booked appointment with Audi of Naperville first thing Monday morning to have them fix whatever was wrong - the earliest appointment I could get was June 11. Drove the car until Wednesday evening when something went very wrong and constant clatter was replaced by loud scraping and brake lockup when I exited 355 on my way home from work. Called someone that night to have it towed to Audi for the next day's service appointment. Audi videoed their inspection and shared the video. Their inspection revealed one caliper entirely missing from the driver side brakes and the other caliper on that brake very loose. I paid Audi personally for that repair. I called Mavis customer service to notify them of my findings. After pulling the shop video from my brake appointment that day, they got back to me and said they would refund me for that appointment, the tow to Audi, and the Audi repairs. I have since been in touch with them and they said they mailed me a check on July 2. Since it has been 17 days since that date and it doesn't take mail that long to get to most of North America, I tend not to believe them. I have since learned that this Mavis brake replacement was negligent and could have resulted in an accident, with the potential of injury. I am contacting you because I don't want Mavis to take their responsibilities for the safety of their customers so casually.

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.

My seat belt warning has been going off intermittently. I received an extended warranty from Audi Subject: Seat Occupancy Detection System Limited Warranty Extension extending the warranty for my car. However, when I took it to the dealer they could not replicate the sound. I provided them a video of it happening. They said it was not showing as a fault on the computer and therefore refused to repair the seat under the warranty extension. This is a safety issue and it's recognized as one by Audi. This sensor is obviously malfunctioning for a lot of people or they would not have extended the warranty. Regardless of being able to "replicate" the issue, they should replace the sensor since it's a known issue and they extended the warranty on it.

A failed (frozen) Turbocharger Wastegate Actuator. An engine warning light came on and engine had less power. It had to be replaced. There was a settled law suit for the same issue covering this item in previous vehicles settled in 2025.
