2021 Audi Q5 E problems

UNKNOWN OR OTHER

On August 11th, 2026 right before noon, the sunroof on my Audi Q5 (hybrid, 2021 model) exploded without warning. Luckily noone was hurt but the explosion alone was enough to distract someone to run off the road. Luckily there were no pedestrians around otherwise they could have been hit by flying glass. And luckily the sunroof cover was protecting me otherwise the glass would have been all over the cabin. I had never heard of exploding sunroofs but have since learned that it’s a known problem. I realize there was an investigation which was eventually called off with no results, but I want you to know that the problem is still there. There was nothing wrong with our sunroof. I wasn’t hit by any debris, it just exploded out of nowhere. I seriously thought I was shot at. I am emailing to bring this back to your attention in the hopes that you don’t shrug this off. The explosion was loud and freaked me out. People could have gotten hurt.

POWER TRAIN

I and my wife were emerging from an intetstate highway entrance ramp when our car suddenly and completely lost power. A "Transmission Malfunction" warning suddenly (and for the first time) appeared on the dashboard.We had just completed a merge with heavy traffic going 70-75 miles per hour. Immediately behind our car was a very large tractor-trailer that hit its brakes but came within inches of the rear of our car before we could get on the highway shoulder--i.e., we came extremely close to suffering serious injury or death. The car was towed to the nearest Audi dealer, where it was determined that the Transmission Control Module had to be replaced, at a cost of $8,000. The warranty on the car is 4 years/40,000 miles, while our car is 5 years, 2 months old, and has 47,000 miles on the odometer. The dealer (Flow Audi of Charlottesville) confirmed the car's problem and determined that, because of the threat to safety, the cost of the repair, and the lack of any previous warning, it should be covered by warranty in spite of the car's age and mileage, but Audi has refused to do so. Audi has been aware of this problem with Q5e (plug-in hybrid) models such as ours, as they have published a Technical Service Bulletin about it (without provision for the affected vehicles to be examined or repaired). The vehicle is still at the dealer for repair (as of 06/08/2026).

ENGINE

Vehicle has an issue with the transmission control, it will not reliably shift into the appropriate gears as it gains speed, often slipping & shuddering, sometimes even slamming into a higher gear. A few times it has stayed in first or second gear as I was pulling onto a busy street into oncoming traffic, I was unable to gain speed without taking my foot off the gas entirely and trying again. This creates a very dangerous situation as I was unable to get to speed, cars did have to slow & go around me as I was not able to speed up I did get a warning light a couple of times, dashboard read "Drive system: Malfunction! Please contact Service" Dealership said it gave the code "P288200," and stated that this indicated "Engine disconnect clutch engagement fault." Audi has a TSB for remedy (Audi Technical Service Bulletin 2070965), in which is stated that "There is a software error in the transmission control module." This indicates that this is an ongoing issue with this component. The dealership that I brought it to was able to replicate the problem when test driving the car. quoted a $537 software update to remedy the malfunction.

WHEELS

The warning lite for the low tire pressure comes on randomly and consistently. I've taken it in about 5 times and have been told the tire pressure is fine and it is just a built in defect. I am concerned because I can't check my tires constantly and especially when I am on the freeway. I fear for my safety, the safety of my passengers and the vehicles around me. It happens on the loaners they give me, so I know it is not just my vehicle. I've talked to corporate and they seem very unconcerned. Can you help at all?' I'm considering selling it because of this issue, but don't want some one else coming back on me about it if they get in an accident.

POWER TRAIN

While driving one day, several warning messages appeared on the dashboard, but would then disappear. The next day, the car engine would not start and the vehicle dashboard would not turn on. The car was inoperable and had to be towed to a dealer service center. Dealer confirmed that the issue was caused by liquid entering the gateway control module. A safety fix had been applied before during a 90S9 recall in 2022, but it appears that fix is inadequate or defective.

SERVICE BRAKES

Reporting a potentially dangerous situation related to the vehicle's braking system. This incident happened on [XXX], on [XXX] in around the Fife WA area. The vehicle is an 2021 Audi Q5 hybrid, purchased new and been taking to dealership for service for every service interval. Initially, the vehicle was in adaptive cruise control, speed set at about 60 miles per hour. Then when the vehicle comes to a congested section of the freeway, the adaptive cruise control tries to slow down the vehicle, but it is about getting close to the vehicle in front, so I manually pressed on the brake and add additional brake force to make sure the vehicle stop in time. About that moment, there were multiple messages showed on the instrument panel, I did not have time to read all of them, but for sure one of the messages said braking system malfunction, and plus the icon with the vehicle and some curve line show up. After I came to a complete stop, and all the message disappeared, (I think the at that time, the vehicle icon with curve line still on), I begin to accelerate again, but then I noticed the brake is not functioning properly. The brake was very tight, I was only going maybe 15 miles per hour at the time and still have hard time stopping. If I would have accelerated to a higher speed, I may not be able to bring the vehicle to a stop safely then. On a busy freeway, I turned on my hazard light, and I drove slowly and safely try to move to an area on the freeway where I can slowly roll the vehicle to a complete stop and I have to push the brake very hard to do so. I reset my vehicle couple of times. Then the brake appears to be working again. But the check engine light came on. Since the braking system is working again at that time, I continue my drive home. After I arrived home, I restarted my vehicle again, and the check engine light disappeared. But please investigate this situation as the safety of the drivers and others are at risk INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA),

FORWARD COLLISION AVOIDANCE: WARNINGS

I have had three occurrences where the Automatic Emergency Braking system and Forward Collision system have been activated for no reason. In one case the Q5 braked suddenly, and the seat belts tightened to the point that it made my passengers back sore. Fortunately, no vehicle was following close behind to cause a rear end collision. I another case I was stopped at a traffic light with a car also stopped in front of me and the seat belts tightened for no reason. It was very startling. The third instance I was driving along a straight 2 lane road with no cars travelling in either direction and the AEB activated. The braking was violent. I am concerned that the AEB could activate on an interstate highway causing a serious accident. The date I used was just one occurance.

FORWARD COLLISION AVOIDANCE: WARNINGS

In several instances, my Audi Q5 has erroneously thought there was a road hazard and slammed on the brakes. It was terrifying. Luckily there were not cars close behind or they would have collided with my car. We took it to the dealer who adjusted the system they call “Pre-sense” but the car still slammed on its brakes for no reason a couple of months later.

VEHICLE SPEED CONTROL

Every possible warning light came on without notice and the car came to an abrupt halt. Ultimately the front tires locked and the car could not be moved out of park. This happened at Yosemite National Park and was very dangerous. Fortunately I was able to glide most of the car to the side of the road (not all) before the complete shutdown of all systems. The car was towed to our Audi dealer. Audi confirmed that it was the Gateway Module that had completely shut down due to "water ingress." This was perplexing because: 1) There had been a recall to fix this issue in similar Audi's about a year ago and we had promptly taken it in for the fix; and 2) We did not spill any water on the back seat nor drive over any substantial water which in any event should not have resulted in a complete system failure based on the fix that had been prescribed for the recall. Audi indicates they have fixed the issue and applied a sealant underneath as an added measure. We are very concerned about how - after the recall fix - this could have happened and want to know what assurance there is it cannot happen again.

VISIBILITY/WIPER

During heavy rain storms, the audi windshield wipers will stop whenever the car is at a stop. This occurs at every setting, auto, low or hi Settings. This is very dangerous especially at a stop light or sign. A pedestrian could be walking in front of your vehicle and because your wipers are not operating you could not see the pedestrian walking in front of your car. Very dangerous!

Six months ago received a warning saying Electrical System Failure: safely stop vehicle. Took it to the dealer. They had the vehicle 30+ days and said they had finally fixed it. Almost immediately began receiving the same error message upon driving vehicle again. Called dealer and asked what to do. They said it must be a sensor problem because they replaced everything. Said it could be ignored. Warning light would come on and then go off periodically but we continued to drive vehicle on dealer's advice. Then, one night, while traveling on a local street, received a warning that there had been a Transmission Failure, and vehicle came to a sudden halt, blocking traffic. Wheels locked, making it extremely hard to get onto a tow truck. Had been driving on the highway shortly before this happened and could have died if the car had suddenly stopped moving at highway speed.
