2018 Audi Q5

The comfort control module catastrophically failed. There is video evidence of the condition the module is in. The whole car shut down. Nothing electronic worked. Doors unlocked, trunk opened, gas cap unlocked, couldn't start car or change gears, roll up/down windows, or lock the doors. The dealership has confirmed the sunroof drains leaked water into the rear left wheel well filling it up with water into the trunk where the spare wheel well is with picture evidence of the amount of water. It rained the night prior. There were no prior warning signs or any issues. Everything was working fine until it was not. The comfort control module needs to be completely rewired and the sunroof drains need to be completely replaces. If this happened while I was driving I would have lost complete control of the vehicle as all power to the car was off.

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.

Regarding my 2018 Audi Q5 34000 miles. Driving on a busy highway a few ounces of water spilled in the backseat. Car lights up like a xmas tree and car came to a screeching stop. Two lanes of high speed traffic on both sides. Fiance just had both hips replaced, Ends up popping one of them out of socket during ordeal. Recall was issued for installation of 'protective cover' over gateway control module. Car received recall work. Part still failed. Audi won't cover the part. I'm out of warranty. Total bill $1800. Dealer has had car 3 weeks. I've been out of pocket for rental car

The sunroof draining is designed in such a way that if the holes get clogged, the water can back up and flood the comfort control module in the rear of the car rendering it useless. That module controls critical parts of the driving of the car like turn signals, the on/off starter motor, which if they fail while on the road make it incredibly dangerous to drive. Audi has already recalled the car to "enclose" the gateway control module but refuses to take responsibility for damage to the comfort control module caused by badly designed sunroof drainage. This incident caused a $9,000 repair that they refused to pay for.

On July 12, 2023 I took my 2018 Audi Q5 to the dealership of Westwood in Audi Massachusetts for an oil change. according to the dealer, the coil mount was broken, and it would lead to coil spring breaking. it is concerning because the car only has 53,000 miles and it’s driven only on the street and it’s not used for off-road and it was never driven hard. Only this dealership ever touched my car and they had never reported any flaws while I had the extended 5-year warranty. This was my first dealership visit for no change without extended warranty. If the coil springs break, I will have no warning so it seems like a safety concern given that the car is relatively new. I searched on the web and apparently 2018 Audi Q5 seem to have a problem with the rear driver side coil springs and coil mount. Did dealership said this is normal wear and tear on the 53,000 mile Audi. They also said that the engine mount would have to be replaced soon in the near future, and they said it was normal wear and tear. I guess the engine could fall on the ground, another safety problem without any warning. Thank you for your time.

We purchased our 2018 AUDI Q5 in May 2018, which currently has 31,567 miles. Having done the majority of the driving, I am pleased overall, and continue to be a proud AUDI owner. However, as with all new cars, we had some glitches. For example, when backing out of the garage, the pre-sense would activate for no apparent reason, causing the brakes to lock up This happened three times and each time the Service Department was able to recalibrate the system. I felt the problem was resolved until recently when it occurred for the fourth time. This is not the reason for my letter but is intended to provide background information I feel is related to a more serious problem. Recently I have experienced situations that concern my safety and the safety of my passengers, not to mention other drivers, especially those immediately behind me. On two occasions while driving on the open road, the brakes have slammed on even though, fortunately, there were no other vehicles or impairments near us. (Incident dates: 05/28/2023 and 06/09/2023.) It was indeed a frightening experience, to the point where my wife will not drive the car believing that the potential for another incident could occur (reference previously mentioned backup issues). My AUDI Advisor, whom I highly regard, has provided me with a five step procedure for bypassing the associated emergency braking pre-sensor(s), which requires being activated with each drive cycle. I did some online investigating and discovered that this is a known problem since at least 2016 as you will read in the attached article. Also included is a related Audi Technical Service Bulletin. https://www.audiworld.com/forums/a4-b9-platform-discussion-212/permanently-disable-pre-sense-2945351/ https://static.nhtsa.gov/odi/tsbs/2020/MC-10176756-0001.pdf Reference Page 7. After years of known awareness on the part of AUDI corporate, I would conclude this work-around is not a fix but a design flaw and known safety risk.

My 2018 Audi Q5 has 53,000 miles per the dealer the coil spring seat is broken. Driver rear spring is broken ,rear coil spring mounts are corroded, and if left on resolved my suspension can fail. The dealer also states that this may result in uneven tire wear poor handling in for fuel economy. It is somewhat confusing because all this sounds like a major safety issue since involves the suspension. A simple, Google search also showed me that I’m not alone, that many customers are experiencing serious, similar problems with low mileage Audi cars. As always, thank you for your time I have all documentation for my car which was purchased at the dealership and serviced at the dealership without any problems being reported until now

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
