2021 Audi Q5 Electrical system Problems

“Q5 has a very serious defect, that is, there is a gateway module located under the rear seat cushion/cup holder. All of the communications to all the controllers go through this little box. If water spills, it collects around the gateway and corrodes it, which will shut down the car. This shutdown occurred while I was driving my family. Lost all power, engine, electrical, everything. Barely coasted out of the roadway. This is a design flaw to locate this sensitive module underneath rear cup holders and will lead to dangerous situations for people in the car.”

“While driving on the highway (70mph) at night, my instrument panel went completely dark. I was not able to see the speed I was driving and my warning sounds/lights were not working. The dealer could not get me an appointment for 4 weeks so I took it to a mechanic who specializes in European cars. The diagnostics indicated a loss of power to the instrument cluster/panel. I was told there was an active recall for this issue, but my VIN was not included. …”

“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. …”

“Virtual dashboard where speedometer and safety warning are displayed has stopped working. Display has completely shut down. I cannot see any critical information to drive vehicle. I contacted the dealership to address a serious safety concern that mirrors an issue already under active recall for other models by the manufacturer. Despite this, the dealership has refused to perform any inspection or repairs, stating that my specific model is not currently included in the recall—even though the symptoms and risks are identical. …”

“The instrument panel cluster assembly (screen behind steering wheel) needed to be replaced because it would intermittently stop working and I had no idea of how fast I was going, what gear I was in, how much fuel I had or whether the lane assist and other safety features were working. Without knowing speed, I may have followed cars too closely to safely stop or I could have run out of gas and left stranded somewhere. I thought it might have been software updates occurring but after a few days, I went to the dealer for service. …”
