AUDI SQ5 Reliability by YearBest & worst years, problems & recalls — NHTSA data

I have. two 2024 Audi SQ6 Prestige vehicles. This has now happened on both of these vehicles while driving them. The axle will snap while driving causing the vehicle to stop and no longer move forward or back. This is extremely dangerous because it occurs when driving and can lead to an accident because the car just stops. Luckily in both instances I was not on the highway and was on side roads so there was no accident. After this occurred the second time, I discovered this is being reported by Audi owners of Q5 and SQ5 models however Audi claims there is no issue. This occurred on both of my SQ5s, once in April and Once in September. Both vehicles had low mileage, 15,000 and 22,000 respectively.

While driving on a freeway, away from any other cars or flying objects, with a large bang, the sunroof exploded. The shade was closed so thankfully no glass entered the car. After getting to the side of the freeway, it was discovered that 1/2 of the sunroof glass was completely shattered and the rest was spiderwebbed. No other object was found in the shade, only small and large pieces of glass.

The rear hatch lid has a mechanism that closes the hatch when foot movement is sensed near the rear bumper. Unfortunately, it sometimes detects foot movement when a person is working on baggage in the luggage area. It then sets off an alarm and attempts to close the hatch on the unsuspecting person. The owner’s manual asserts that there is built-in pinch-protection to stop the hatch and avoid injury if an obstruction is detected. It does not work; the hatch closure can’t be stopped with reasonable force. Two injuries have already occurred. The dealer has said that the pinch-protection cannot be improved, nor can the foot-sensor be desensitized.

What component or system failed or malfunctioned, and is it available for inspection upon request? AUDI PRESENSE SENSOR IS GOING OFF RANDOMLY WHEN THERE IS NO RISK FOR COLLISION. BRAKES ABRUPTLY, SEATBELT TIGHTENS, CAR TURNS OFF IN THE MIDDLE OF THE ROAD. FROM LEASE START WEEK 1TO FEB 2024 How was your safety or the safety of others put at risk? IN SEVERAL CIRCUMSTANCES WE HAVE COME WITHIN INCHES OF GETTING REAR ENDED BY PEOPLE DRIVING BEHIND US AT A HIGH RATE OF SPEED, AS WELL AS GETTING PUSHED INTO ONCOMING TRAFFIC RISKING BEING HIT HEAD ON (WHILE WAITING TO TURN LEFT FOR INSTANCE) Has the problem been reproduced or confirmed by a dealer or independent service center? THE DEALERSHIP TOLD US THEY PERFORMED A DIAGNOSTIC AND THE COMPUTER DIAGNOSTIC SYSTEM DID NOT REPRODUCE OR CONFIRM AN ISSUE. WE HAVE HAD OUR YOUNG CHILD IN THE CAR WITH US WHEN THIS HAS HAPPENED ON MULTIPLE OCCASSIONS AND HE WENT INTO THE DEALERSHIP WITH US TO EXPLAIN WHAT HAPPENS. THIS IS 100% MALFUNCTIONING/ DEFECT/ LIFE SAFETY ISSUE. WE DON'T KNOW WHY THE COMPUTER CAN'T PICK IT UP (IT DOESNT ALWAYS HAPPEN DURING THE SAME CIRCUMSTANCES AND CAN BE RANDOM) BUT WE CANT DRIVE CAR AS WE BELIEVE WE WILL EITHER BE KILLED DRIVING IT AND COULD CAUSE FATAL HARM TO OTHERS- CAR AT DEALERSHIP Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? THE DEALERSHIP ONLY TO DATE Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? WHEN THE VEHICLE STOPS SUDDENLY (WITH NO DANGER PRESENT) A WARNING LIGHT COMES ON THE DASHBOARD, ALONG WITH AN ALARM. THE SEATBELT TIGHTENS IN A TERRIBLY AWEFUL WAY, THE CAR BRAKES TO A SCREECHING STOP AND TURNS OFF ALL OF THIS HAPPENS ON ITS OWN AND IT HAS HAPPENED EVEN WHEN WE WERE AT A RED TRAFFIC LIGHT WITH NO CARS/ NO MOVEMENT AROUND US. WE NEED HELP! THIS PART HAS NOT BEEN RECALLED BY AUDI TO-DATE AND WE KNOW 100% THAT THIS IS A SERIOUS SAFETY ISSUE

1–2 second delay in throttle response from pedal input, followed by sudden uncommanded surge/jerk forward. Occurs when vehicle is on hold mode in a slope or in plain flat conditions at a light or a stop sign. It happens when the car is cold or warm. I consider the vehicle unsafe to drive. The cruise control also has a major problem. When activated the lane departure feature also gets activated automatically but instead of making the car more stable it moves the card left and right all the time without any major interaction from the driver. I have to deactivate the lane departure function all the time in order to feel safe.

The contact leases a 2025 Audi SQ5. The contact stated that the driver's side exterior rear-view mirror position was blocking the driver's view while making a left turn. The manufacturer was contact and advised the contact to take the vehicle to the dealer for it to be test-driven. The dealer was notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 800.

I was driving out of a parking lot into the feeder road of a highway with the intent of immediately getting on the highway. When I attempted to accelerate the car would not go any faster. I was traveling perhaps 5-10 miles per hour as cars on the feeder road were approaching at 45-50 miles per hour. The lag time before the car would accelerate was about 20 seconds. Luckily, I had not entered the feeder road right as the feeder road traffic was near me, otherwise I would definitely have been hit. This lack of acceleration happened two other times but the lag time was shorter. I took the car to the dealer but they could not find the problem.

We bought the car today at Audi South Atlanta brand new and were driving back home. The car suddenly showed the engine light, showed drive system malfunction please safely stop, and then the car slowed down and stopped on the highway. The steering stiffened up and almost caused a car crash. It was very dangerous. The Audi dealership said that software issues were all resolved before allowing the purchase of the vehicle today, but this dangerous malfunction still happened.

While driving at normal operational speeds, the vehicle suffered a sudden, un-commanded, and catastrophic loss of motive power while navigating a live traffic intersection. The transmission completely disengaged all gears without warning, rendering the vehicle entirely stationary and immobilized in the path of oncoming traffic. This failure created an immediate, severe safety hazard, exposing the occupants to a high risk of a side-impact or rear-end collision due to the inability to clear the intersection under the vehicle's own power. The vehicle had to be flatbedded to an authorized dealer (Audi - Glenwood Springs). The professional diagnostic evaluation confirmed an internal failure of the transmission assembly and Transmission Control Module (TCM) / Mechatronic unit, requiring a total replacement of the powertrain assembly. The failure occurred at 59,000 miles.

My car has a known issue with a piston skirt defect that can cause engine failure. Audi of America acknowledged this issue with the EA839 and only warranted an 80k mile warranty. I am outside of that warranty and in risk of catastrophic engine failure that could lead to safety issues on the road. I am worried about my safety in driving this vehicle. Audi of America refuse to cover my car as it is outside of the extended warranty. There are numerous people that have the same issue as several models with the same EA839 engine and are prone to this failure.

The contact owns a 2021 Audi SQ5. The contact stated that the vehicle was taken for routine service at the dealer, and the contact was informed that the coolant pump was starting to fail. The contact was advised that the mechanic found coolant running through the vac lines. The contact was informed that continuing to drive the vehicle with a failing coolant pump could cause engine damage. The contact had the coolant pump replaced. The manufacturer was not informed of the failure. The contact researched online and related the failure to NHTSA Campaign Number: 18V229000 (Engine and Engine Cooling); however, neither the VIN nor the model year was included. The failure mileage was approximately 39,000.

Component/System: Engine and Cooling — Water Pump / Coolant System Vehicle: 2021 Audi SQ5 Engine Code: CWGD Mileage at Failure: 71,000 Date of Incident: 8/6/2025 Audi Denver I’m reporting a known defect affecting my 2021 Audi SQ5 with engine code CWGD. The engine experienced an internal coolant leak from the water pump housing, which is a known issue previously acknowledged by Audi in TSB #19Q5 2022 01, covering earlier 3.0T engines (DEWA/DEWC). Although my engine (CWGD) is not listed in the bulletin, the failure is identical in nature: the plastic thermostat/water pump housing fails internally, leading to coolant loss and potential engine overheating. This issue is widespread among Audi 3.0T engines, including CWGD, and poses a risk of engine failure and overheating. Audi has extended the warranty for earlier engine variants but refuses to cover mine, even though the defect and consequences are the same. This inconsistent coverage leaves owners like me exposed to high repair costs for a clearly known design flaw. I am requesting that NHTSA investigate whether Audi’s CWGD engines should also fall under the scope of the extended warranty or safety defect coverage already applied to DEWA/DEWC engine variants. Audi’s selective VIN or engine code exclusions appear arbitrary and may allow known safety-related failures to go unaddressed. Documentation available: dealer inspection report confirming internal water pump leak, warranty denial letter, and TSB copy.

MMI not connecting Control module for emergency call module

Comfort Module J393 failed that is tied to all electronics warnings in car. brake warnings, light warning, security warnings, etc. Car was unable to be started as a result. If these electronics failed during driving, its very dangerous and could force crashing of vehicle. According to Dealership, failed module was submerged (ie water flooeded). This is a self contained electronics module that is not exposed to elements. The car was parked in driveway. it rained lightly over the weekend. Then this occurred. the damage and replacement cost was over $10K in damage. Audi dealership stated replacing rear water drain may be kinked or damaged causing water to leak where module located. Its not normal for self contained electronics modules to have this problem.
