Audi Q7 won't start problems

Filed Mar 17, 2026 · NV

Start/Stop button will not start the engine at times. May take several attempts before engine will start. Had to have Audi Roadside Assist come to my location to get the vehicle car started. Drove vehicle to nearest dealer with the "engine light" illuminated. Was advised that Audi has a software update that needs to be installed. Update was supposed to drop by week 10 of 2026 but it is still not available as of week 12. Audi and the dealer cannot provide a resolution after vehicle has been in shop for 3 weeks. Was told that I could pick up the car since they did not see it as a safety issue, but if the vehicle if often unable to start why would one trust driving it?

The starter in my Audi Q7 2019 failed and the car would not start. I was parked in my garage and manually had to put the car in neutral using the tool provided in the trunk and push the car out of the garage until a flatbed tow truck was able to take my car to the shop. If this happened elsewhere, I could have been stranded without the ability to start my car. My car was towed to a certified shop where they confirmed the failure and made the repair by installing a new starter.

Water leakage into the driver’s side floor panel. Water leakage seeped into battery compartment below driver’s seat which is a result of a sunroof drain problem. New Battery was installed for only 3 months before the low battery charge warning light came on. Car will not start at times. Water leakage into electrical components that lead to the MMI not turning on or working at all. The MMI shut off first, then the battery became faulty. The car has been jumped at least 10 times due to the water damage, which proposes a risk to the driver. The electrical components are being flooded, which is a safety issue and proposes a safety hazard to the driver and all passengers. The electrical is at risk for further damage.

Turned on the car and within a few minutes smoke filled up the whole car. The smoke was coming from the rear wiper from the inside. Seems to be coming from the wiper motor but can't tell until I take the plastic cover off. Started smoking immediately every time I turned the car on, tested it a total of 3 times. Strange caramel colored residue left on the back window from the inside. Smells terrible. The car was stationary the whole tome and parked in a neighborhood. Surprised a fire didn't start because of the amount of smoke. Some research on this saying some people had an actual fire inside the car.

This complaint pertains to audi's adblue (nox) system. The nox sensor failed, when the car is driving or stationary. The warning alert states the car will not start within 600 miles. The nox sensor must be replace; otherwise, the car will not run due to the software lock out triggered by the sensor. I am forced to repair the car despite the fact the tdi adblue system never worked properly as advertised by vw/audi. In my view, vw/audi should replace the sensor or vw/audi should offer a reimbursement for any cost related to the tdi adblue system that occurred while the court case is pending.
