2018 AUDI Q5 Complaints

My 2018 Audi Q5 has a water intrusion issue with control module damage. The vehicle reduce speed to 15 mph on the highway, when parked the lights would not shut off. The vehicle would then not turn on. Thirty minutes later the vehicle started. I received a front passenger seatbelt malfunction and several controls went out. The passenger seatbelt would not recognize there was a passenger buckled in the seat. The lights stayed on. The windshield wipers started on their own. The car wouldn’t recognize the key fob. Later the turn signal malfunctioned, along with the front lights staying on but the rear light and license plate light would not come on. At the dealership they found water in the comfort module housing, left rear quarter panel/wheelbase and said it was probably caused by the pressure vent seal allowing water to enter damaging the comfort module and 56 wires. They stated the vehicle was unsafe and inoperable. They also were not able to roll the windows back up or lock and secure my vehicle. The issues with the vehicle speed occurred 5 weeks ago. The dealership changed the thermostat but the speed reduction happened again afterwards once but when it was turned off and turned back on the speed went back to normal. Then today the vehicle just went crazy with things turning on and other controls not working, like the taillights. Multiple times I have told the dealership of the seatbelt malfunction. They said it was probably the seat detecting something on the seat, like a bag but couldn’t account for the malfunction when the seat was occupied. The vehicle is now at the dealership with plastic taped around the opened windows and unsecured since the locking controls will not work. They suggested I file a claim with my insurance for the repair. This screams defect to me!

Jan. 2023 my coolant pump had blockage which caused the coolant hose to break and discharge coolant all over my engine and overheat. I have the repair receipt from Audi Dealer and requested a copy of the inspection report from them. Pictures also attached. I also have my car at the Audi dealer as we speak due to a week later the car would not accelerate properly with a Drive System Malfunction error light, which is now the Turbo Charger needing replacement. Towed to Audi Dealer on 2.7.2023 and waiting for Turbo Charger delivery, currently on back-order. These are not normal wear and tear items on a vehicle with 53,000 miles.

Two issues. My temperature housing unit is leaking coolant. This car has very low mileage and is barely driven so it is very strange that this part is already defective. Seems the original integrity of the part may not have been good. Second, My Audi pre sense comes on while the car is driving and brings the car to a screaming halt as is there is something in the cars path. The problem is there is nothing in the cars path when this feature kicks in . It’s quite dangerous as this has happened to me while driving on busy roads .

During a normal service visit it was brought to my attention that the rear suspension coil was broken. They attributed this to normal wear and tear after only 52,000 miles. Upon research it seems this is far more common in 2018 Q5s than it should be this is early.

I was trying to park my car in my office parking space, after right turn to parking space, I applied brake to stop, but the car suddenly accelerated and within few seconds it crashed into the office building. I was still applying brake when it accelerated and I could not do anything else. The fact that vehicle climbed two levels of curbs to hit the building shows that the acceleration was out of my control. And even vehicle's collision system did not kick in when car was climbed over the curb. Polic report #: 22-350-0239C Agency: SCCSO

Rear coil spring on passenger side broke and became detached, wedging against lower control arm. Coil spring had no signs of other damage; seems to be defective metallurgy (see attached photographs). Vehicle had 55,645 miles on it. Dealer charged $720 to repair. From online search, there seems to be a high number of Audi Q5's from 2018 model year with this problem, but Audi dealers claim it is a 'normal wear' item and is not covered.

Two issues: 1. We have needed to repeatedly replace brake booster. 2. Passenger side rear spring has broken and dealer is indicating the driver side should also be replaced.
