2018 Audi Q5

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

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.

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 .

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

The cars emergency brake system malfunctioned on our 2018 Audi Q5 Premium Plus, causing the brakes to lock up for no reason while traveling on a busy street at 35 mph. The force of the braking was enough to cause a bruise from the seatbelt. The risk is potential loss of control of the car, especially if this occurred at a higher speed, or being rear ended. We immediately took the car to an Audi dealer who could not ID an issue from looking at fault codes. We have been experiencing other bogus warning messages: light system warning (nothing wrong), engine RPM exceeded warnings (engine RPMs never close to being exceeded), phone SOS errors. NO warnings or symptoms regarding the brake system. Dealer says to monitor. We have been driving the car for about a week since, and have not experienced the same issue again.

It says driver system malfunction. Day before that it says Auto Start and Stop malfunction failure. When you are the traffic light and slow down and take a turn then the car gives kinds of couple of pushes as if the It gearbox is not able to adjust the speed automatically . You need to accelerate to keep the balance of the Car. Every passenger of the car feel the same. After 2 days I started getting Driver system malfunction warning. The car is not safe to drive on highways or local road as gearbox has some issues. There is a class action lawsuit for the similar problem which Audi did not address yet. https://margarianlaw.com/audi-class-action-lawsuit/
