2018 Audi Q5

In early July, 2023 various warning and fault lights began to show on the dashboard: engine start system, brake lights, start/stop system, and others - indicating malfunctions with systems important to safety. Also, the car alarm system sounded without cause and key pods would not lock/unlock the doors electronically. These warning lights proliferated over several days. We took our car into our local Audi dealership. They diagnosed the problem as follows: "Performed GFF and found code for 3393 comfort system control module replacement. Control module faulty due to control unit being submerged in water and fried the control unit. Water leak due to rear drains clogged causing the water to overflow. Performed/fixed the water leak, cleaned out the pools of water that have accumulated, replaced the control unit 3393 comfort system control module, performed control unit replacement test plan and program keys." The Audi Q5 is well known to have design/parts problems in the sunroof drainage system. As has occurred in thousands of other Q5s, those issues caused the rear cargo area to flood, frying an important electronic component and activating warning/fault lights for a range of other systems. Malfunctions in several of those systems could have caused critical safety issues. We are fortunate because we decided to take our Audi directly to the dealership service center. Repairs cost several thousand dollars.

My 2018 AUDI Q5 had the 5-year/50,000 mile factory recommended service in August 2022, the vehicle only hadwith 42,000 Miles and everything was perfect as it was the last year of the five year service extended contract. In July 2023 I was told the engine mounts needed to be replaced. Both mounts and vehicle has 53,000 miles. Basically mounts cannot the engine and transmission in place .This recommendation was done as part of the 60,000 mile recommended factory service based on my Google research. Many Audis have disorder failure which is which can be catastrophic because there are no warning lights for the engine mount failure when the car auto stops and starts it shakes. This has hung always been a standard, but annoying feature of the car, which cannot be turned off for emission purposes. Clearly the engine mounts cannot handle the auto start/stop of the vehicle. That’s why it’s failing for so many vehicles. It is frustrating given that the car is a $54,000 car and at 53,000 miles I run the risk of the engine falling on the ground , this information is widely available on the Internet easily accessible on Google. I ask that you please look into it. thank you for your time always . What is bizarre is that now when I accelerate hard, I can feel a little vibration of the engine before I didn’t but that’s something I cannot explain at the moment. The dealer that sold me the car brand new is the only dealership that has ever touched my car, and my car was always serviced as recommended once a year

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.

Hello, My Q5 top view(360) camera. The MMI wont be able to save my settings - when it is changed from Graphic to Camera. It always goes back to default as Graphic. I need to adjust almost every time when I park the car. It is distracting and safety conerning. This issue came with the car since it was bulit. And this is the common issue across the MY18 for Audi products. Audi dealer needs to charge me to fix the issue, due to the car is out of warrenty. But this is not caused by wear and tear. Thanks,

Our 2018 Audi SOS signaling device was built on 3G. Audi now tells us it is no longer available and will not fix the problem. For the record 3G was introduced in 2001 and 4G in 2009. Why did Audi use 3G in my 2018 model? Was it was some executive who made the choice because I can’t fathom an engineer choosing 4G over 3G. This is the message we are receiving from Audi USA. https://www.audiusa.com/us/web/en/inside-audi/innovation/audi-connect/layer/legal/3g-downturn-faq.html ...The following Audi connect services will no longer be available following AT&T’s 3G turndown: Audi connect CARE’s SOS and emergency call feature, online roadside assistance, Audi Service Request, and Audi incident assistance, remote lock and unlock, vehicle status report, and stolen vehicle locator...

As I was driving down the freeway, I heard a loud boom/explosion sound. I was instantly covered in glass, as my sunroof had exploded. I was not driving under an overpass, and there was no truck throwing rocks around me. Upon inspection, the remaining glass around the hole in the sunroof was pointed upward, showing that the glass exploded up, rather than something breaking down into the sunroof. I am very lucky that I was able to keep my car on the road and not cause an accident, as the sheer loudness of the explosion, and the glass falling all over me were huge safety risks. There have been zero warnings/symptoms with the sunroof prior to this incident, and I had the fabric cover opened, as I did not know that this could happen, which allowed the glass to fall all over me as I was driving on the freeway.

There is a module under the back seat called the J533 that I am told got wet. This completely shut down the entire car as my wife and child were driving down the highway. We were very disheartened to find out that this is an out of pocket expense for a common thing to happen in the back of an SUV. After searching online, I came across this link, which is an identical account: https://www.audiworld.com/forums/q5-sq5-mkii-discussion-218/control-module-ruined-moisture-corrosion-3001605/ I'll highlight one area in this link thread, as it most strongly relates to your questions above: "Audi (VOA) faces considerable legal exposure for any injury caused by a liquid finding its way into a component that poses such a high risk of harm if the module fails. . which evidently it does via corrosion following moisture intrusion of some sort. This is particularly the case given the absence of any mention or warning in the manual about avoiding spillage, and more pertinent to liability, Audi’s failure to anticipate the considerable risk of harm stemming from a readily foreseeable occurrence, ie, spillage. To frame it in more stark terms, no one reasonably expects to face a death ride when they spill their soda."

I WAS ABOUT TO GET ON THE FREEWAY WHEN MY CAR'S ELECTRICAL SYSTEM FAILED AND I GOT SEVERAL WARNING LIGHTS. THE BRAKING/STOP START SYSTEM, LIGHTS AND A FEW OTHER LIT UP. I PULLED OFF THE ROAD AND HAD IT TOWED. THE DEALERSHIP SAID WATER (RAIN) GOT IN THROUGH MY SUNROOF AND SHORTED MY SYSTEM (WARRANTY WON'T COVER). THERE ARE SEVERAL CLASS ACTION SUITS RE. THIS ISSUE ALREADY AND AUDI KNOWS ABOUT IT, BUT THERE'S NO RECALL AND CARS HAVE STOPPED SUDDENLY ON THE FREEWAY. IT'S VERY DANGEROUS.

I'VE HAD SEVERAL ISSUES WITH MY VEHICLE WHEN BACKING UP AND THE PRESENCE GOING OFF WITHOUT A REASON. WHEN BACKING UP ON SEVERAL OCCASIONS, THE SENSORS WILL BEEP AND BRING THE VEHICLE TO GRINDING STOP. WHEN I CHECK THE AREA, THERE ARE NO VEHICLES, PERSON, OR OBJECTS IN THE PATH OF THE VEHICLE. RECENTLY, WHEN DRIVING ON THE HIGHWAY, THE PRE SENSE WENT OFF WHEN NO VEHICLES WERE AROUND AND SLOWED THE VEHICLE DOWN AT A RAPID RATE. TWICE WHEN DRIVING, THE PRE SENSE WILL ACTIVATE AND BRING THE VEHICLE TO A COMPLETE STOP WHEN THERE ARE NO VEHICLES IN FRONT, BEHIND, OR BESIDE ME.

THIS IS NOT AN URGENT SAFETY ISSUE, BUT JUST A DUMB DECISION THAT SHOULD BE RECTIFIED. IT IS ALSO LIMITED TO DRIVERS UTILIZING HITCH OR OTHER REAR-ATTACHMENTS. THERE ARE CERTAIN SITUATIONS WHERE THE PARKING SENSORS CAN BE TOLD TO STOP BEEPING, BUT THAT ACTION ALSO DISABLES THE BACKUP CAMERA, WHICH IS NEEDED. THERE IS NO MECHANISM TO TURN OFF THE BEEPING AND KEEP THE BACKUP CAMERA ON. SERVICE CENTERS HAVE CONFIRMED THIS. THE MAIN SCENARIO WHERE THIS IS A PROBLEM IS WHERE THERE IS SOMETHING CONNECTED TO A HITCH, SUCH AS A BIKE RACK THAT MAY CAUSE THE CAR TO THINK THAT THERE'S AN OBJECT DANGEROUSLY CLOSE TO THE VEHICLE. THESE BACKUP SENSORS ARE UNABLE TO DISTINGUISH BETWEEN A HITCH-BASED MOUNT (WITHOUT POWER CONNECTED) AND SOMETHING THAT IS LEGITIMATELY TOO CLOSE WHILE REVERSING. WHEN POWER IS CONNECTED, SUCH AS WITH AN ACTUAL TRAILER TO SUPPLY POWER TO BRAKE LIGHTS, THE OWNER'S MANUAL STATES THAT THE BACKUP WARNINGS WILL BE DISABLED AUTOMATICALLY. BUT WHEN SOMETHING LIKE A HITCH-BASED BIKE RACK IS ATTACHED THAT DOESN'T NEED POWER, THE WARNING ALARM SOUNDS CONTINUOUSLY WHILE BACKING UP. THIS IS ANNOYING, AND FOR PASSENGERS IN THE BACK IS ACTUALLY EXTREMELY LOUD. TURNING OFF THE ALARM DISABLES THE CAMERA AS WELL, WHICH IS....LESS THAN IDEAL AT LEAST. THE DESIRED MODE SHOULD BE TO TURN OFF THE ALARM WHILE KEEPING THE BACKUP CAMERA ACTIVE DURING THE ENTIRE REVERSING PROCESS. THE BEEPING WILL STOP AUTOMATICALLY ONCE THE VEHICLE STARTS MOVING FORWARD FASTER THAN SOMETHING LIKE 6MPH. HOWEVER, WHEN THE VEHICLE SLOWS DOWN AGAIN, IT MAY START A CONTINUOUS TONE ALARM AGAIN DUE TO THIS HITCH ATTACHMENT. PLEASE HELP AUDI REALIZE THAT DISABLING THE CAMERA IS INAPPROPRIATE.
