2020 Audi Q5 Electrical Problems

Electrical system failure due to water in the spare tire & battery well, purchased key fob, 2 auto batteries unable to program fob due to non compatible 1st battery, info display contact dealer, had the water extracted, there were no prior indicators of an upcoming issue until the morning of May 22,2026 when my vehicle wouldn't start so I called roadside assistance for a boost. The key symbol is constant on display now, after over 2mos @the dealer, made several calls to Audi Corp, Audi. com, Audi USA., Consumer Protection, Texas Lemon law , it was shown to have an active recall. I was advised to contact my insurance company, which was denied seems as though no resolve for an actual ongoing Audi issue. I'd hate to be driving & the vehicle comes to an abrupt stop & put lives in danger from a known ongoing recall issue by Audi. Thanks in advance for your attention to this matter. Regards,

Engine Start Malfunction Warning Light. Apparently, this has been a problem with the 2020 Q5 (and others) from water backing up from clogged moonroof drainage system allowing water into the L rear compartment housing the Comfort Control Module, wiring, fuses, etc. (or other roof drainage problems also saturating the CCM) Dealership has determined that damage to the CCM and corroded wiring will cost about $5500 to replace and program. Audi, I believe. sustained a class action lawsuit and agreed to cover that problem with the moonroof drainage system up to 90000 miles. However, my vehicle is at 114000, but I never received any type of notice of there being a problem or that the drainage system should be evaluated from Audi. And this had to have been occurring for years for system corrosion and failure. This apparently can cause the vehicle to freeze in the middle of driving, which is a significant risk, as well as other problems of inability to access vehicle and multiple other warning lights. The warranty for this problem should be extended to cover damages incurred from the poor drainage system design and improper notification of such by Audi.

We were driving today at around 11:30am and all of a sudden the “Audi Presense” light came on at the same time the car brakes abruptly slowed down the car for about 5 seconds or so and then released. Today is a beautiful sunny day and there were no vehicles anywhere or anything in roadway on the road we were traveling on. The jerking /abrupt slowdown really surprised us. We will go to Audi dealer asap but now we don’t trust when it will happen again. A car could have hit us from behind.

The car was constantly smelling like smoke. It felt like it was going to catch fire. I got it serviced when it had to be serviced at 15k but Audi dealership did not warn of any recall and mentioned everything was great with the car. In the end I had to sell the car which was in April, 22 because I didn’t feel safe driving the car anymore. I would also constantly get airbag being deployed warnings on the screen and one time the car shut down automatically as I was driving at about 45Mph going up the mountain

Gateway control modular failure. At dealer currently. We took pictures. Multiple reports of the exact same thing on Audi forums online. Audi confirmed same issue. While driving car it suddenly stopped and the emergency brake was automatically applied. No warning, no way to Live the car to safety, all the warning lights began to flash, windows started to rolling up and down. Then the car just turned off. Unable to start it, turn it on, move it, nothing. Needed a special tow truck to have it towed to dealer. A serious safety issue. I am 8 m pregnant, had my brother and 4 year old nephew in car. I am concerned for my safety but equally concerned for every Q5 has this gateway module in this location. Every person driving a Q5 and other drivers can be affected by the design flaw of the location/ lack of protection of this gateway module. We were lucky we were not on the highway. What if this happened on a highway at high speeds or in a curve.

I RECENTLY PURCHASED A 2020 AUDI Q5. IT WAS 6 WEEKS OLD AND HAD ABOUT 2300 MILES ON THE ODOMETER. WHEN PULLING OUT OF A PARKING SPACE THE CAR DIED. I COULD NOT GET IT STARTED NO MATTER WHAT I DID. I COULD NOT EVEN GET THE FLASHERS TO TURN ON (TO THE IRE OF THOSE TRYING TO EXIT THE LOT.) AFTER HAVING IT TOWED (I WAS ON VACATION, NO LESS!) I LEARNED THAT THE ELECTRICAL DISTRIBUTION SYSTEM WAS DEFECTIVE AND HAD TO BE REPLACED. I AM JUST GRATEFUL THIS DID NOT GIVE OUT ON A 55 + MPH HIGHWAY, WHICH COULD HAVE BEEN LIFE THREATENING. ALSO, SINCE THE GEAR SHIFT IS ELECTRIC, THERE IS A WAY TO PUT THE CAR IN NEUTRAL FOR TOWING PURPOSES. THIS SYSTEM DID NOT WORK AND MY CAR HAD TO BE TOWED BACKWARD WHILE IN DRIVE.

OVERALL PROBLEM: AUDI Q5 2020 APPEARS TO HAVE A COMPUTER MALFUNCTION THAT INSTANTLY DISABLES ALL SYSTEMS. VEHICLE 'SHUT ITSELF OFF' AT A BRIEF STOP AND BECAME VERY DIFFICULT TO CONTROL, ROLLING INTO INTERSECTION. DETAILS: I STOPPED CAR AT RESIDENTIAL NEIGHBORHOOD STOP SIGN (BRIEF AND COMPLETE STOP, NO WAIT), IMMEDIATELY READY TO PROCEED FORWARD. AUDI'S 'AUTO STOP/START' FEATURE SHUT OFF THE ENGINE, THEN IMMEDIATELY ALL ELECTRONICS SHUT DOWN. THE CAR BASICALLY 'TURNED ITSELF OFF.' VEHICLE THEN BEGAN DRIFTING/COASTING INTO INTERSECTION. CONTROLS WERE UNRESPONSIVE. I REALIZED THE POWER BRAKES AND POWER STEERING WERE DISABLED. I BRAKED VERY HARD, WHICH STOPPED THE CAR. HAD TO KEEP BRAKES PRESSED VERY HARD TO KEEP CAR FROM MOVING. IGNITION BUTTON WAS UNRESPONSIVE. I THEN NOTICED A SMALL MESSAGE ON THE DASHBOARD CONTROLS WHICH READ SOMETHING LIKE 'START/STOP IGNITION SYSTEM DISABLED ' PUT CAR IN P.' (THIS WAS THE ONLY WORKING ELECTRICAL FEATURE I NOTICED, THE EVENT WAS FRIGHTENING AND DISORIENTING, BUT I'M FAIRLY SURE NOTHING ELSE WAS FUNCTIONING). I THEN SHIFTED GEARSHIFT TO PARK, AND WAS ABLE TO START THE CAR AND DRIVE AWAY. I REPORTED PROBLEM TO DEALER. DEALER CLAIMED TO INSPECT VEHICLE, AND SAID THEY WERE UNABLE TO FIND ANYTHING WRONG. DEALER SAID VEHICLE'S COMPUTER HAD NO RECORD/MEMORY OF THE INCIDENT. DEALER ALSO SEEMED RESISTANT TO PROPERLY DOCUMENTING THE INCIDENT ON THEIR PAPERWORK. I REPORTED THE PROBLEM TO AUDI CORPORATE IN AUBURN HILLS MI, EXPLAINING I NO LONGER FELT SAFE DRIVING THIS CAR, AND WOULD NOT DRIVE IT AGAIN. AUDI CLAIMED TO PERFORM THEIR OWN INVESTIGATION, AND THEIR BRIEF REPLY SAID THAT THEY WERE NOT OBLIGATED TO DO ANYTHING UNDER APPLICABLE LEMON LAWS. CAR WAS IN 3RD MONTH OF LEASE, ~150 MILES. PREVIOUSLY I DROVE AN AUDI A4 2017 FOR 3 YEARS SO I WAS/AM VERY FAMILIAR WITH THE WAY AUDIS OPERATE.
