2018 AUDI Q5 Forward Collision Avoidance Problems

Safety System Malfunction message appears on dash. Passenger side air bag goes on and off while driving. Whole system chimes and random messages flashing on screen constantly. At times system doesn’t recognize that I have my drivers side seatbelt buckled. So system keeps chiming cars Stanton. Random messages flash on dash. Traffic jam assist (3 cars symbol) unavailable and image flash on dash and does another chime. Vehicle has given random warning beeps when reversing 2 times since these issues started and has done automatic breaking both times as I was trying to reverse. Issues happen randomly and started about 300 miles ago (2 weeks or so) seem to be getting more frequent in past few days. I was trying to check today for open recall and was surprised to not have any for this issue / vehicle. I have not yet called the dealership but plan on doing so this week. This “Safety System Malfunction” and all the chimes, flashes, beeps, screen messages and the automatic vehicle responses is VERY dangerous!!

The contact owns a 2019 Audi Q5. The contact stated that while driving at an undisclosed speed, with no other vehicles or objects nearby, the Forward Collision Avoidance system unintendedly activated. The contact stated that within seconds, the Forward Collision Avoidance: Automatic Emergency Braking system engaged, greatly reducing the speed before returning to normal functionality. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to diagnose the failure with Forward Collision Avoidance system. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 60,000.

Mileage: 60,000

While driving, the power steering completely went out and lost the ability to steer, while on the road. There were no prior warnings or feeling in the steering to present a possible future failure of steering under power. Put myself, my wife and the other operators at risk as I lost all power steering and had to pull over immediately. I have a current repair order open at a local shop and the PSM module has failed, of course requiring a full steering rack replacement to the tune of +$5k.

While driving, the steering wheel suddenly locked up and could not be turned. Several warning lights simultaneously appeared on the dashboard including: "Steering malfunction! Please stop vehicle", "Audi adaptive light malfunction! See owners manual", "Start/stop system malfunction! Function unavailable", and "Audi pre sense currently limited" - No warning lights were present prior to this event. The sudden loss of steering could have caused serious injury to myself and to other drivers or pedestrians nearby. I was thankfully able to stop the vehicle, but I could not pull over because the steering wheel could not be turned. The car was towed to the Audi dealership and I was told the "Electronic power steering rack" would need to be replaced costing nearly $5,000.00.

The panel showed vehicle lights malfunction. The side marker lights are on all the time. This happened without any accident or changes of the setting.

Such incident happened two times: when I was driving at normal speed, another vehicle quickly approached me from back while switching to my lane. Out of any instruction, my vehicle applied brakes to decelerate. This almost caused crash and put my safety at high risk!

This was unintentional acceleration case: When I got into the parking space, the car was almost stopped and I was about to press the park button (gear) and the car suddenly accelerated and in a fraction of a second, climbed the curb, crashed into the fence, broke the fence and crushed on a tree. I was still applying brake to stop it and I could not do anything else. The following facts show that the acceleration was totally out of my control. 1.vehicle climbed the curb 2. and climbed the dirt part, shrubs 3. to hit the fence and broke it; It looked like something mall functioned. As a matter of fact, no safety feature worked and no sound signals went on ! Even vehicle's collision system did not kick in when car was climbing over the curb. Fortunately, I could get out of that car and my body was aching due to the seat belt and airbag explosion. (Driver side bag exploded for sure. I do not remember if the other side bag exploded.)

I have a 2018 Audi Q5. The electrical system basically went into complete failure, and upon taking it to the dealership, was told the sunroof draining system "clogged" and the flooding caused by this caused the damage. After significant research online, I have noted this seems to be a very well-known issue.

recently on a number of occassions the car stopped because the pre-sense sensor went off prematurely. There were no cars within 500 feet of my car on all occassions. Now the Pre-Sense has completely turned off and will not turn back on

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/
