2021 Audi Q5 Complaints

Vehicle Information: 2021 Audi Q5 Component Affected: Electrical System / Electronic Control Unit (Body Control Module / BCM2) Description of Safety Defect: The vehicle suffered a catastrophic failure of the Body Control Module (BCM / BCM2) caused by water ingress originating from a defective rear sunroof drainage tube assembly. The manufacturing failure of the panoramic sunroof drain allows water to pour directly down the vehicle's interior D-pillar. Because of a severe design flaw, Audi positioned this highly critical central electrical computer completely unshielded in the exact cargo cavity where this water runoff pools. When the Body Control Module shorts out due to this water ingress, it creates an immediate and severe safety hazard. The vehicle experiences sudden, unpredictable electrical malfunctions while in motion, including the risk of uncommanded engine shutdown, a total loss of exterior lighting, failure of the central locking safety systems, and a disabled key transpond...

We took our 2021 Audi Q5 to the Audi dealership because our vehicle seemed to be skipping gears and making jerking motions while driving. I believe it began happening at least a couple of months ago when my wife noticed a change in driving dynamics. She is the vehicle's sole driver. After taking it to the Audi dealership and driving with the technician in the passenger seat, a diagnosis was made immediately while backing from the parking space. The technician indicated there was no need to go any further because he could determine it needed a differential fluid change. He also indicated it was a common problem with this model Q5 and it is occurring at a high rate with these vehicles. This was a $512.38 (with a 25% discount) expense that should not have occurred for a vehicle this age which was purchased new from this manufacturer. This should not be happening with this vehicle and shouldn't a recall have been made for such a frequently occurring problem? Please investigate and reply

When attempting a left-hand turn, despite the oncoming vehicle already passed me, the Audi auto-breaks leaving me in the center of the oncoming lane and causes the vehicle behind me to almost crash into me. Very dangerous.

VIN number: [XXX]. Audi Q5 Prestige 2021 Mileage 48,540 I have contacted Audi Corporate regarding a catastrophic Transmission Failure while driving. The dealership investigation discovered that bolts had loosened and the fluid was not getting to the transmission and it stopped dead while I was driving. I was on surface streets going to pick up my baby granddaughter from daycare. I heard what sounded like a "slip" in the gears, a yellow notification appeared stating that the car is safe to drive. A few minutes later it happened again and the same warning appeared. I continued to the daycare and in the driveway the car stopped dead with a Red warning that it is a transmission malfunction. I luckily was not in a busy intersection or the freeway as that would have been catastrophic for my life and the life of my young granddaughter. I have contacted Audi via telephone at [XXX]. They took my statement and gave me a case number: XXX. I have worked with my Audi dealership and they are givi...

On 8/3/26, my 2021 Audi Q5 began throwing numerous different malfunction/error alerts and the engine turned off while driving after a bottle of water had partially spilled onto our backseat behind the drivers side. The vehicle was towed to a nearby mechanic who determined that liquid damaged the gateway control module located under the backseat of the vehicle, as the gateway control module is placed in a "protective cover" (an unsealed plastic bag) and that bag visibly had liquid inside of it. We had immediately contacted Audi upon learning of this issue and decided not to move forward with any repairs, but to instead pay out of pocket to have it towed 70 miles to Audi/where we originally purchased the vehicle. This "protective cover" the control module was placed inside was completed as a recall service repair on our vehicle in April of 2022 due to a NHTSA recall announced in December 2021 regarding safety issues in these control modules failing from liquid spills on the backseat. We...
