2018 Audi Q5 Complaint Log

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.

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

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.

The check engine light came on so I stopped at the nearest auto repair shop and the codes came back that the thermostat was sticking partially closed and the water pump was leaking.

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.

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.

THIS VEHICLE HAS ELECTRICAL ISSUES. THIS VEHICLE WATERPUMP FAILED TWICE WHICH I HAD TO REPAIR THIS VEHICLE GIVES WARNING SIGN’DRIVE SYSTEM MALFUCTION’ CODES DIRECTING TO TURBO CHARGER BUT IT IS ACTUALLY THE WASTEGATE THATS THE ISSUE-WHICH I HAD REPLACED AFTER THROWING A NEW TURBO. THIS VEHICLE HAS ISSUES WITH THERMOSTAT WHICH I HAD REPLACED TWICE. I HAVE PAYED ALL REPAIRS OUT OF POCKET AND UNTIL TODAY THERE IS NO RECALL.SOMEONE PLEASE TAKE A LOOK INTO THIS MATTER ANY INFORMATION NEEDED FROM ME OR MY MECHANIC I CAN BE CONTACTED VIA EMAIL -: [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Brought to dealer for routine maintenance and was told both rear springs are broken and need to be replaced. Last time it was in the shop was for a safety inspection in March with no reported issues with springs. the springs are a critical suspension component and put me and others on the road at risk every time I drove it due to rollover, loss of control and bottom out potential while driving. Yes dealer inspected and confirmed the component failure and suggested replacement. No indication on dashboard or warning lights.

The car is totalled. My car tripped 9+ malfunction warnings, after starting and driving. These included rear brake lights, directionals, start/stop system, and more. It appears that the sunroof leaks, and the roof drains were clogged (even though they were specifically checked and cleaned by the dealer 2 months earlier). This led to water accumulating in the areas under the back seat (a prior recall which allegedly had been addressed...NHTSA campaign number: 21V947000. Audi’s number for this recall is 90S9.), and in the rear wheel well area, where electronics control modules live. The car eventually had to be towed to the dealer. It was initially estimated to cost $9,500 to repair. But, after several weeks, more water was found and it was declared not worth repairing.

The contact owns a 2018 Audi Q5. The contact stated that while starting the vehicle in a severe rainstorm, the vehicle experienced electrical failures, which included the head lights flashing and the horn activating before the vehicle suddenly became inoperable. The vehicle was towed to the local dealer who discovered that rainwater had leaked into the rear of the vehicle and the electrical components were submerged in water causing an electrical failure. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The contact stated that the vehicle was previously serviced under the NHTSA Campaign Number: 21V947000 (Electrical System, Structure). The failure mileage was 53,000.

My 2018 Audi Q5 has a water intrusion issue with control module damage. The vehicle reduce speed to 15 mph on the highway, when parked the lights would not shut off. The vehicle would then not turn on. Thirty minutes later the vehicle started. I received a front passenger seatbelt malfunction and several controls went out. The passenger seatbelt would not recognize there was a passenger buckled in the seat. The lights stayed on. The windshield wipers started on their own. The car wouldn’t recognize the key fob. Later the turn signal malfunctioned, along with the front lights staying on but the rear light and license plate light would not come on. At the dealership they found water in the comfort module housing, left rear quarter panel/wheelbase and said it was probably caused by the pressure vent seal allowing water to enter damaging the comfort module and 56 wires. They stated the vehicle was unsafe and inoperable. They also were not able to roll the windows back up or lock and secure my vehicle. The issues with the vehicle speed occurred 5 weeks ago. The dealership changed the thermostat but the speed reduction happened again afterwards once but when it was turned off and turned back on the speed went back to normal. Then today the vehicle just went crazy with things turning on and other controls not working, like the taillights. Multiple times I have told the dealership of the seatbelt malfunction. They said it was probably the seat detecting something on the seat, like a bag but couldn’t account for the malfunction when the seat was occupied. The vehicle is now at the dealership with plastic taped around the opened windows and unsecured since the locking controls will not work. They suggested I file a claim with my insurance for the repair. This screams defect to me!

The right rear coil spring broke after only 52,679 miles. The car was NEVER taken off road and most of the mileage was on highways. It was driven by my wife, who is a very conservative driver. The dealer discovered this. The independent shop to which I took it for a second opinion stated that the coil spring looked like new but had a break in it, which they've never seen with a car in pristine condition and such low mileage. Both the dealer and independent shop stated it was a hazard and needed to have both rear coil springs replaced, since although only one was broken it was mechanically necessary to do both. The public Audi Forum [https://www.audiworld.com/forums/] posts show that several other vehicles of the same model and more interestingly the same model year had the same problem. This is clearly a safety issue and a manufacturing defect. I have uploaded photos I took of the coil spring after it was deinstalled from the vehicle.

The contact owns 2018 Audi Q5. The contact stated that while driving approximately 25 MPH, there was an abnormal grinding sound coming from the rear of the vehicle. The vehicle was immediately driven to the local dealer who diagnosed that the rear driver’s side suspension coil spring had fractured also causing damage to the rear axle and rear differential. The vehicle was not yet repaired. The manufacturer was not yet contacted. The contact stated that the vehicle had experienced the failure previously. The failure mileage was 60,000.

The contact owns a 2018 Audi Q5. The contact stated that the air bag warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed that the air bag control module had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 85,600.

Rear suspension coil spring was broken, with only 62,000 miles. This sounds similar to the problem with this car's cousin, the 2018-19 VW Tiguan, which had a recall. (https://www.consumerreports.org/car-recalls-defects/volkswagen-recalls-cars-suvs-springs-could-break/)

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.

The contact owns a 2018 Audi Q5. The contact stated that while driving at an undisclosed speed, the vehicle had dealt with a loss of automotive power. A warning message "Shut off Engine, Check Cooling" had appeared in the instrument panel. In addition, the contact stated that the engine temperate gauge had risen. The vehicle was towed to a local independent mechanic, where it was diagnosed with a cracked coolant line. The vehicle was repaired twice however, the failure had occurred. The vehicle was taken to another local independent mechanic for a second opinion where the vehicle was diagnosed and repaired however the failure occurred twice again. The local dealer was contacted however, the vehicle was not diagnosed or repaired due to cost. The manufacturer was made aware of the failure. The failure mileage was approximately 170,000.

During a normal service visit it was brought to my attention that the rear suspension coil was broken. They attributed this to normal wear and tear after only 52,000 miles. Upon research it seems this is far more common in 2018 Q5s than it should be this is early.

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

Two issues: 1. We have needed to repeatedly replace brake booster. 2. Passenger side rear spring has broken and dealer is indicating the driver side should also be replaced.

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 .

When a front seat passenger is present, the passenger airbag warning light comes on with a "malfunction" error displayed, then goes off.

Both rear coil springs observed to have failed (broken) upon bringing car to mechanic for brake job. Less than 60k miles.

Both rear springs broke. Possible risk to wheel and arm support. No towing, road hazard or excessive load. Car has 48,000 miles. Others reported same problem on Audi members site. Unable to reach Audi USA. Dealer says my problem.

Rear coil springs broke. No heavy duty cycle. 46,000 miles. Spring retention pads dislocated and destroyed. Powder coat anti rust prevention in 90% good shape. No reason for coil springs to break other than assembly defect or supplier material defect.

While driving at a relatively low speed, approximately 30 mph, I approached a red light and proceeded to slow down. The brakes did not engage, so I continue to pump them but had to swerve into the right lane to avoid hitting the car in front of me. Fortunately, there wasn’t a car in the right lane. It was raining but not heavily, although earlier we did go through heavy rain on the freeway. After this incident we still had to drive about 5 more miles to get to our destination. The brakes worked the rest of the way. I took the car to Audi to have them check it and they said they didn’t find anything; however, this was certainly some sort of brake malfunction.

Rear coil spring on passenger side broke and became detached, wedging against lower control arm. Coil spring had no signs of other damage; seems to be defective metallurgy (see attached photographs). Vehicle had 55,645 miles on it. Dealer charged $720 to repair. From online search, there seems to be a high number of Audi Q5's from 2018 model year with this problem, but Audi dealers claim it is a 'normal wear' item and is not covered.

Took the vehicle to the local dealer for a car damage repair but notified at multi-point checks that the thermostat housing is leaking coolant. It ran 43K miles only and this is a known issue so should be recalled.

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.

On 02/14/2022. Car just died while waiting for cars to pass to turn at light. Dashboard started flasing "engine start system: malfunction! - Please contact service" then "Parking Break Malfunction!" then, "Steering: Malfunction! - You an can continue driving" Panicked because was holding up traffic. After a couple minutes trying Car then just started drove home and put on battery charger overnight. Hoping that's all it was. Next morning 02/15/2022 started right up early morning no issues to be concerned with was on highway doing approx 69 mph, drove approximately 42 miles then then while only driving 35 mph 4 lane highway. Again, No warnings, but while DRIVING Engine and steering, just shut down. Almost causing me to be reared and then hit on passanger side. I don't even want to think what could have happened had this happened on interstate or if my children were in the vehicle. It was a very dangerous and scary situation even happening while only doing 35 mph. This should be considered a MAJOR recall. Vehicle was towed on 02/16/22 to Clearwater Audi. We did not receive vehicle back until after over 9 weeks, 04/22/22. Yesterday, 06/07/2022 Sensors glitching again and being called back into dealership. I want this life threatening recall documented. There is absolutely no reason why a well cared for vehicle with less than 18,000 miles should be having these issues. We We keep losing out on time from work and driving back and forth to dealership. We need to be able to rely on the safety and integrity of this vehicle not only for the driver/passangers but for the safety of others on the road. Thank you for your time to hear our concerns

Have been receiving an intermittent warning: Safety malfunction for the passenger airbag. The light comes on intermittently. Comes on most often when no one is sitting in the front passenger seat. If I place a small bag (handbag, purse etc.) on the seat sometimes the light goes off sometimes it does not. If someone is sitting in the seat the malfunction light is not present. The dealer confirmed the malfunction stating: They found the safety malfunction light is being triggered by a faulty passenger front seat pod and needs to be replaced for $2,233. Doing a quick Audi forum search have found numerous individuals with similar complaints and many have even reached out to Audi. This appears to be a significant safety issue as it calls into question the reliability of airbag operation in the case of an accident.

REAR HATCH RANDOMLY OPEN DURING OPERATIONS AND WHILE SITTING PARKED.

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...

Panoramic sunroof leaked water into the car's electrical system during a rainstorm (despite being closed tight), resulting in a total failure of the car's electrical system, potentially a catastrophic occurrence. Fortunately the electrical failure happened when the car was stationary.

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.

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/

The 2nd generation Audi Q5 (roughly 2017-2021+) has a major susceptibility to immediate, catastrophic failure as evidenced from my own experience and dozens of episodes reported online. This failure typically causes a $2000-$3000 repair bill that Audi will not cover and will claim is the fault of the owner. My wife was driving the vehicle with our 5-year-old daughter in the car In the middle of the rear seat. The daughter spilled part of a 500 ml water bottle onto the seat next to her. Within 20 seconds of this happening, the car began alerting about steering malfunctions, braking malfunctions, and the windows began seizing up and down repeatedly. The car was completely inoperable. We are lucky this was on a slow city street and not on the interstate or tollway! Once stopped, we no buttons generated any actions from the vehicle. we couldn't power it on, put it into neutral to be towed away, raise the windows, or perform ANY other function at all. The car was a useless brick. We were charged $125 for the towing service and another $2200 from Audi Plano in Texas. After countless conversations, even debates, with David (director Audi Plano) and even Audi USA customer experience team, they REFUSED to admit any fault in a poor design and help cover any of the costs whatsoever, and we are even still in warranty. The part that was damaged is DIRECTLY below the cupholders and has no effective liquid protections - what did they think would happen! Here are other examples from online: https://www.audiworld.com/forums/q5-sq5-mkii-discussion-218/water-bottle-leak-%241800-damage-3009540/ https://www.audiworld.com/forums/q5-sq5-mkii-discussion-218/control-module-ruined-moisture-corrosion-3001605/page5/ https://www.mumsnet.com/Talk/shopping/3641294-Audi-Q5-taken-out-by-DD-water-spill-in-rear-seat https://www.nhtsa.gov/recalls?nhtsaId=11350209

We got a screw in our tire while driving on the highway and received a low tire pressure indicator. We kept driving, not knowing it was a screw, until we could find a rest stop. Before we were able to reach a safe place to stop, the entire tread of the tire came off while we were driving, immediately disabling the car.

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.

WHEN PRESSING THE BRAKE PEDAL AT TIMES YOU HEAR A METAL CLANG SOUND LIKE SOMETHING HITTING A TIN CAN. THIS HAPPENS OFTEN BUT IS NOT CONSISTENT. I HAVE VIDEO EVIDENCE OF THIS AS WELL AS HAVE SEEN THIS ITEM DISCUSSED IN DETAIL OF AUDI FORUMS. AUDI CLAIMS REGARDLESS OF MY EVIDENCE NOTHING CAN BE DONE. MY CONCERN IS IT HAS TO DO SOMETHING WITH THE BRAKE AND TO ME IS A SAFTEY CONCERN*DT

CAR STATIONARY ON HIGHWAY AFTER TRAFFIC CAME TO A STOP DUE TO A TRAFFIC INCIDENT AHEAD. REAR ENDED BY VEHICLE GOING IN EXCESS OF 40MPH. CAR PUSHED INTO CAR IN FRONT (CAR 3), SPUN AROUND AND HIT THE SAME CAR (CAR 3) IN THE FRONT. AIRBAGS DID NOT DEPLOY. BOTH DRIVER AND PASSENGER WERE ADMITTED TO THE HOSPITAL WITH INJURIES.

TL* THE CONTACT OWNS A 2018 AUDI Q5. THE CONTACT STATED THAT WHILE DRIVING AT 65 MPH, THE ENGINE SHUT-OFF AS THE CONTACT WAS FORCED TO COAST THE VEHICLE TO THE SHOULDER OF THE HIGHWAY. THE CONTACT ATTEMPTED MULTIPLE TIMES TO RESTART THE VEHICLE. ENGINE FAILURE - CONTACT DEALER, MESSAGE WAS DISPLAYED ON THE INSTRUMENT PANEL. DUE TO THE FAILURE, THE CONTACT HAD THE VEHICLE TOWED TO AUDI TULSA (4208 S MEMORIAL DR, TULSA, OK 74145) WHERE THE VEHICLE WAS DIAGNOSED WITH A DEFECTIVE FUEL SENSOR. THE DEALER REPLACED THE SENSOR AND THE FUEL TANK AND THE VEHICLE WAS RETURNED TO THE CONTACT. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE VEHICLE WAS REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 27,260.

TWICE IN 2019 MY CAR SLAMMED TO A STOP WHILE BACKING UP AT 2-3 MPH. I HAD NOT HIT ANYTHING AND NO DAMAGE TO CAR. THERE WAS NOTHING TO HIT, JUST A VACANT AREA. YESTERDAY WHILE DRIVING FORWARD AT 35-40 MPH ON A MAIN STREET WITH THE CLOSEST ONCOMING CAR 1 BLOCK AWAY MY CAR SLAMMED TO A DEAD, WALL SLAMMING STOP. IF A CAR HAD BEEN BEHIND ME THERE WOULD HAVE BEEN AN ACCIDENT. I EMPHASIZE: THIS WAS A DEAD, NO SLOW-DOWN STOP. I REFUSED TO DRIVE IT 50 MILES TO THE DEALER. THE DEALER HAS PICKED IT UP AND TOLD ME THE SENSORS WERE SET TOO SENSITIVE. IF SO, WHY DID THIS NOT OCCUR EVERY TIME I DROVE? FRANKLY, I AM AFRAID I WILL BE FORCED TO DRIVE THIS CAR FOR THE NEXT 3 MONTHS UNTIL MY LEASE EXPIRES. THE DEALER WILL NOT GIVE ME A LOANER. I THINK THIS IS A VERY UNSAFE CAR. I HAVE NO CONFIDENCE IN THE WAY THIS IS BEING HANDLED. FOR YOUR INTEREST, I WAS GIVEN A RIDE TODAY IN THE 2019 SEDAN MODEL. UNBELIEVABLY IT SLAMMED TO A STOP WHILE BACKING OUT OF MY DRIVEWAY.

CAR SUDDENLY TIED WHILE DRIVING IN CITY; ENGINE/ALL SYSTEMS SHUT OFF. IT TOOK SEVERAL HOURS FOR ROADSIDE ASSISTANCE TO ARRIVE, AND THE 1ST 2 TOWING COMPANIES COULD NOT DISENGAGE THE BRAKING SYSTEM TO LOAD ONTO TRUCK! ONCE VEHICLE TOWED TO AUDI DEALER, THEIR DIAGNOSIS WAS "GATEWAY CONTROL MODULE J533, WATER IN CONTROL MODULE, CORROSION IN CONNECTOR, CAUSING FUSE FOR GATEWAY CONTROL UNIT TO BLOW" WE WERE TOLD BY DEALER THAT "LIQUID MUST HAVE SPILLED INTO AREA BEHIND REAR SEATS". WE HAVE NO YOUNG CHILDREN, AND NOBODY WAS RECENTLY SITTING IN REAR SEAT. VEHICLE IS PARKED IN GARAGE AND IS IN EXCELLENT CONDITION; 2 YEARS OLD / 24,000 MILES. THIS WAS A $3,200 REPAIR NOT COVERED UNDER WARRANTY. THIS SOUNDS LIKE A DESIGN DEFECT. AFTER SEVERAL COMMUNICATIONS I HAD WITH AUDI USA AND LOCAL DEALER, THOSE (2) PARTIES TOLD ME THIS REPAIR WOULD BE COVERED AS A "GOODWILL ADJUSTMENT" NOT A "WARRANTY ITEM". I FOUND SIMILAR REPORTS ONLINE: HERE IS A DISCUSSION I STARTED ON AN ONLINE FORUM: HTTPS://WWW.AUDIWORLD.COM/FORUMS/Q5-SQ5-MKII-DISCUSSION-218/CONTROL-MODULE-RUINED-MOISTURE-CORROSION-3001605/PAGE3/ ANOTHER ONE I FOUND: HTTPS://WWW.AUDIWORLD.COM/FORUMS/Q5-SQ5-MKII-DISCUSSION-218/COMPLETE-ENGINE-CONTROL-MODULE-FAILURE-2952745/ ATTACHED IS INVOICE.

WE ENDED UP RENTING A CAR FOR A WEEK-LONG ROAD TRIP AS THE DEALER LOANER IS ONLY FOR LOCAL USE.

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.

AUDI PRE-SENSE BRAKING FAULT; RECALL NEEDED! 1- WHILE MOVING FORWARD ON AN EMPTY, FLAT, 2-LANE, SUBURBAN ROAD AT APPROXIMATELY 35MPH, THE BRAKES SUDDENLY ACTIVATED, BRING MY VEHICLE TO A NEAR STOP, WITH A LOUD, GRINDING SOUND.
