2018 AUDI Q5 Recalls, Complaints & Safety

The rear view camera is not operating when shifting to reverse. I can demonstrate this malfunction at any time to anyone. Driver is unable to detect short objects or small children directly behind the vehicle. The problem was confirmed by the dealer during a service visit. At that time, the service technician checked power and ground to the control unit and verified good. Attempted calibration for camera, vehicle would not calibrate. The vehicle has not been inspected by any other agencies. There were no warning messages, or lamps or any other symptoms prior to the failure.

The Seat Occupancy Detection System is malfunctioning. The passenger airbag warning light activates when a passenger occupies the passenger seat and the passenger overhead reading light remains on when the seat is occupied including overnight. These are established symptoms of Seat Occupancy Detection System failure. The manufacturer issued a warranty extension specifically covering this defect for 10 years and unlimited miles. When the vehicle was presented at an authorized dealer for diagnosis and repair under the warranty extension, the service advisor deliberately omitted the airbag warning light symptom from the repair order and inserted pre-emptive warranty denial language before any diagnosis was performed. The airbag system malfunction remains unrepaired despite an active manufacturer warranty extension covering this exact defect. The dealer’s failure to properly document and address an airbag warning light constitutes a safety concern that NHTSA should investigate.

Problem with Brake booster servo issue comes on the dash then goes away. Brakes are spongy and brake pedal makes a swooshing sound when pressed

I am submitting this complaint to report a safety defect involving a 2018 Audi Q5 (Premium Plus, Technology Package). The vehicle’s MMI infotainment/navigation system intermittently shuts down or reboots during operation. When this occurs while the vehicle is in in reverse, the rearview camera display immediately goes blank and remains unavailable until the system completes its reboot cycle. This failure has occurred during active reversing maneuvers, creating a significant safety concern. An incident already occurred that resulted in an impact to another object during backing and the camera display/MMI going blank loss just prior to stopping. The rearview camera is a required safety system under Federal Motor Vehicle Safety Standard No. 111. When the system powers off unexpectedly, the driver loses critical rear visibility information at precisely the moment it is most needed. The condition appears to be software-related, as the infotainment system restarts on its own. However, the temporary loss of the camera display increases the risk of collision with pedestrians, other vehicles, or stationary objects. I understand that recalls have been issued for similar rearview camera display failures in later model-year Audi Q5 vehicles. The symptoms I am experiencing are materially similar and may indicate a broader defect pattern affecting earlier production years. I have attempted to resolve the issue with Audi and their technicians and service management. The conclusion was they could not find any error messages or mechanical issues. They would not diagnose deeper or complete any further trouble shooting. The previous owner also attempted to resolve the safety defect under warranty and received similar attention with no solution. I respectfully request that NHTSA review this matter for potential investigation to determine whether the 2018 Audi Q5 should be included in any safety-related corrective action. Of note, the "CarPlay" use is not the cause.

Yellow warning light..drive system malfunction. Red warning light..low oil pressure at idle. Says stop engine..after engine restart lights go off and is fine.. for a little bit.

The front subframe on the vehicle is severely rusted and corroded through rust. Part of it has fallen off, and the rest of it is badly damaged. A structural integrity, a major safety risk. The Audi Dealer inspected it and confirmed. The car is unsafe to drive.

Unpublished costly catastropic electrical failure Audi of America reviewed the case and declined assistance solely because the vehicle was already totaled and unavailable for dealer inspection. Audi did not dispute the presence of water intrusion, the technical findings, or the cause of failure. This failure occurred without warning under ordinary environmental conditions and resulted in sudden loss of vehicle function. I am submitting this complaint to document a potential defect related to the protection and placement of electronic systems vulnerable to water exposure. I am submitting this complaint to report a potential safety-related defect involving water intrusion and catastrophic electrical failure in a 2018 Audi S5. After a heavy rain event with no roadway flooding or submersion, my vehicle experienced complete electrical failure and would not start. Inspection revealed water intrusion into the trunk area where critical electronic components—including the battery and electronic control modules—are located. The damage was extensive and rendered the vehicle inoperable, resulting in a total loss determination. Attached documentation includes photographs, video evidence, and a technical inspection summary prepared by an independent automotive service facility and reviewed in consultation with Audi-trained technicians. The findings indicate water intrusion consistent with design vulnerability rather than misuse or lack of maintenance.

Vehicle: 2018 Audi Q5 Prestige Mileage: Approximately 34,000 miles On December 14, 2024, while driving at normal road speeds, my vehicle suddenly lost power and displayed multiple warning messages, including drivetrain and system malfunction alerts. The vehicle became unstable and unsafe to operate while I was in traffic, forcing me to carefully maneuver off the roadway. This occurred without any prior warning or abnormal engine behavior, it was just so sudden. I brought the vehicle to an authorized Audi dealership the following day. After inspection, the dealership diagnosed a catastrophic internal engine failure, identifying a cracked/chipped valve in cylinder 3. The dealership technicians and service staff stated that this type of failure is extremely rare on a vehicle with such low mileage and normal maintenance history. They also indicated that they had not encountered this type of valve failure on a similarly maintained Audi vehicle at this mileage. There was no evidence of carbon buildup or abuse, and no external contributing factors were identified. The failure resulted in sudden engine malfunction and loss of drivability while the vehicle was in motion, creating a significant safety risk. The dealership recommended replacing the engine cylinder head, with an estimated repair cost approximately $9,100. The dealership could not confirm whether debris from the damaged valve remained in the engine or whether the repair would fully mitigate future safety risks. I am submitting this complaint due to concerns that this failure represents a potential manufacturing or materials defect that can lead to sudden engine malfunction or loss of power while driving, posing a safety hazard to vehicle occupants and other road users.

On 10/27/25 as I was slowly pulling into a parking space, my Audi Q5 lurched forward and jumped the curb crashing into a tree. Happened too quickly to apply the brakes. No warning indications at the time of the incident. Car would not start and had to be towed to a repair shop. The insurance adjuster is evaluating the damage, probably the vehicle will be totaled. Luckily the tree stopped the car and nobody was in in front as the car jumped the curb.

1 injured

Car displayed a warning sign that safety system malfunctioned. Airbag indicator showed “passenger airbag off”. This error occurred sporadically and for a limited amount of time. It also kept sensing that passenger seat was occupied when it wasn’t. From what I understand , the issue is related to passenger side PODS sensor.

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.

My car randomly rebooting while driving. The whole MMI goes down

The vehicle stalls and does not move forward while I was driving it stalled. I had to allow it to roll freely out of traffic.

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.

BCM

The contact owns a 2018 Audi Q5. The contact stated that while driving 35-40 MPH and accelerating, the vehicle lost motive power. The contact pulled to the side of the road, and the vehicle was able to restart. Several unknown warning lights were illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed that the body control module(BCM) was floating in water. The vehicle was not repaired. The local dealer was not contacted. The manufacturer was contacted and informed the contact that the vehicle was previously repaired under NHTSA Campaign Number: 21V947000 (Electrical System, Structure), and the additional repairs were at the contact's expense. The contact stated that the recall remedy was inadequate for the failure. The failure mileage was approximately 58,000.

The contact owns a 2018 Audi Q5. The contact stated while driving 40 MPH, the air bag warning light illuminated. The vehicle was taken to a dealer; however, the vehicle was not diagnosed due to the cost. The vehicle was not repaired. The contact stated that the failure persisted. The contact stated that the warning light was intermittently illuminated. The manufacturer was not notified of the failure. The failure mileage was approximately 120,000.

A coil that is attached underneath the sunroof is attached to the BCM. There is not a drain plug at the end so there was 5 inches of water there and the BCM was made to sit in that spot. The electrical wires and BCM were burned out because of this. The BCM controls the entire system not limited to the start button and everything that runs the car. I have only had the vehicle less than 1 year and it costs 4000 dollars to fix. My car has been at the dealership since June 9th.

The contact owns a 2018 Audi Q5. The contact stated that while pulling into a business at an undisclosed speed, there was an unknown warning light illuminated, and the message "Left and Right Rear Signal and Center Rear Brake Light Malfunction" was displayed. Additionally, the contact stated that the key warning light and engine malfunction warning lights were illuminated. The vehicle was taken to a dealer where it was determined that there was water intrusion into the rear cargo area of the vehicle, due to a clogged drain. The contact was informed that the drain tube needed to be cleaned, the module needed to be replaced, and the vehicle needed to be rewired. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 83,000.

My vehicle spontaneously began displaying emergency signals including engine malfunction, turn signal malfunction, parking brake malfunction, brake light malfunction. I would also turn the car completely off and brake lights would remain on asymetrically. Also, the related alert bells would go off intermittently. I have kept my car in good repair and on a regular maintanence schedule. I took the car first to my mechanic who evaluated and said I should take to the Audi dealership. After two days of diagnosis, they came back that the sunroof drains were clogged with debris which definitively caused water to enter and soak the "comfort module" After irrigating them, they did not find any damage and said they do not need replacement. However, the water soaked and heavily corroded the comfort module and say the entire module needs to be replaced along with a rebuild of the harness. They are quoting me $12,300. My safety was at risk in the malfunction of the engine system, and especially signalling capabilities and possible brake impact. The problem has been confirmed by two mechanics - mine and Audi I searched online and have discovered a number of other 2018 Audi Q5 owner accounts of the same and similar defect and result.

The rear passenger side suspension coil was found broken with a clean break but embedded into the coil boot during a 70k service at the Audi dealer with ~61k miles. No alarming condition of the failure was present, and if it would have dislodged while at speed on the interstate would have resulted in complete loss of control and bodily harm to the driver as well as other vehicles on the road. This was a CPO vehicle garage kept and routinely serviced by Audi, yet they denied any liability and provided no assistance when I escalated to corporate due to being out of CPO warranty by ~2 months. As a result, I had an independent VW specialist shop perform the work, document the observations as if they were to be subpoenaed in the future, and provide me all the parts from the repair (which I still have). The spring coating is completely intact on both rear coils and during the repair process it is evident that the part number has changed from what was originally installed to the current version. The clean break suggests part defect either in design for use or in the spring manufacture. Further investigation on various Audi forums as well as the NHTSA shows this is a prevalent failure for the 2018 Q5 and Audi should be doing something about this.

Turns out numerous complaints about water finding its way onto the computer comfort module. It is well known. Audi techs admitted it is due a bad design by Audi. There are no indications or warnings something is going wrong. Module gets fried and vehicle shuts off. Can't even shift or take out of Park. Insurances do not want to cover due it being water related. Audi does not want to repair due to no recall. They want approx $10,000.00 per occurrence when this happens. Definitely not fair to consumers to have to pay this or total their vehicles. My car only has 50k miles.

Fuel pump has been recalled on other models but not mine. I have a 2018 audi q5. It had a warranty extension but the previous owner never claimed but if it would have been a recall then I wouldnt be having this problem . Now I have to replace the water pump and pay almost $2k for something that wasn't a recall.

WATER SEEPED INTO COMFORT CONTROL MODULE VIA BLOCKED SUNROOF DRAIN HOSES AND DAMAGED ELECTRICAL. THERE WAS A RECALL FOR THE SAME ISSUE REGADING THE GATEWAY CONTROL MODULE WHICH ALLOWS SHOPS TO ADD A PROTECTIVE COVER. THIS SAME RECALL NEEDS TO BE ON THE COMFORT CONTROL MODULE SINCE THE WAY THEY DESIGNED THE SUNROOF DRAINS ALLOWS FOR WATER TO SEEP INTO THE CC MODULE. THIS IS A RIDICULOUS DESIGN THAT REQUIRES A 11K DOLLAR REPAIR FOR CUSTOMERS.

The contact owns a 2018 Audi Q5. The contact stated while driving 30 MPH, the vehicle started to vibrate abnormally with the message "Engine Fault Detected" displayed. The driver was able to pull to the shoulder of the roadway, where the vehicle stalled and was unable to restart. The check engine warning light was illuminated. The vehicle was towed to an independent mechanic, who diagnosed a failure with the connecting rod bearings, resulting in damages to the engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 49,000.

Gateway control module on engine coolant system

I have owned the car for 2 years, purchased a 2018 Q5 from an Audi dealer. Within the first year, my thermostat failed causing the car to lose power and turn off while driving with my newborn baby. I also received the passenger airbag alert daily, which I did see there was a recall for this prior to buying the car. I also received the “add a quart of oil” message about 3 months after an oil change. I would like this car to be reviewed for excessive oil consumption. At the times of these messages no oil leak was found. Now, my car went in for an oil change and an oil and transmission oil leak has been found. Within 2 years of owning a car that has had regular maintenance, I have spent over $6,000 on service and repairs, which is unusual. I need help.

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.
