Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials. Every record below is an owner-reported complaint about the 2018 Audi Q5 submitted to NHTSA — not a confirmed defect, not a recall and not a manufacturer bulletin. 9 reports on file name it.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

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.
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.
My truck was part of a recall regarding my water pump and coolant leaking. I went for service at the Naperville Audi dealership and they basically gave me the run around and didn’t honor the recall lied and said they replaced my thermostat and never did. I had my car towed twice on 10/22 basically left stranded. Audi corporate advised them to fix my car due to the recall and they failed to do so.
On May 3, 2024, while driving to work, the vehicle acutely started to make a loud clicking noise in the engine compartment. I parked the vehicle and looked for a warning light indicator on the dashboard to determine the problem, but no indicator light emerged. I then called Audi Omaha and spoke with the Service Manager who kindly arranged to have my vehicle picked up and a loaner dropped off. I did ask at that time whether it was safe to have somebody drive my vehicle to Audi given the severity of the noise and I was told that since there was not a warning light on the dashboard, it would be ok. I later discovered that my vehicle stalled on the way to Audi Omaha and required a tow. On May 6, 2024, I received a report of the problem and the estimate for repairs. It was explained that the head of a spark plug had broken off into the engine causing the piston to make contact with the valve in cylinder 3 resulting in engine damage which was beyond repair. Additionally, a second spark plug had been misfiring for several days. The estimate to replace the engine: $9,282.03. To my surprise, the multi-point vehicle inspection report I received on the same day reported that everything (aside from rear brake pad wear) passed inspection – including the engine and spark plugs! On May 7, 2024, I called Audi Omaha to express my concern that an entire engine would need replaced on a 6-year old luxury vehicle with only 60,000 miles and spark plugs that were replaced at 40,000 miles prior to my purchase of the vehicle. Even more concerning is that no warning light indictor ever displayed on the dashboard (despite being informed that the vehicles computer system had detected changes in the engine compartment 2-days prior to this event). Because of these glaring safety concerns, this issue was escalated to the Audi central region division who declined to provide assistance despite the faulty spark plug and the malfunction of the warning indicator light.
Quattro Ultra shift fork inside the rear differential is faulty due to inferior material used in production. This defect is acknowledged in the TSB circa 2020, attached. I have experienced hesitation upon a start up from the stop/start function at intersections and other cross traffic situations increasing risk of collusions in fast moving traffic. There is a warning message that states you may continue to drive but to get service. It operates intermittently. I have the defective part following its replacement on a low mileage 2018 Audi Q5 2.0. that is approximately 5 years old at approximately 41,601 miles.

1.I HAD AN ACCIDENT AT APPROXIMATELY 10:45 A.M. ON THURSDAY, SEPTEMBER 19, 2019 IN THE PARKING LOT FOR THE MEDICAL OFFICES LOCATED AT 2000 SOUTH MAYS STREET, ROUND ROCK, TEXAS. 2.I PARKED IN A SPACE ON THE SOUTH SIDE OF THE BUILDING, WHICH IS PART OF THEIR PROPERTY. 3.MY NORMAL HABIT IS TO PLACE THE CAR IN 'PARK' WHEN I STOP IN A PARKING SPOT. 4.SINCE IT WAS VERY WARM, I LEFT THE MOTOR RUNNING SO I'D HAVE AIR CONDITIONING AS I PLACED THE SUN SCREEN OVER THE WINDSHIELD. 5.THE SUN SHADE IS ONE PIECE AND TAKES A LOT OF TIME AND EFFORT TO PROPERLY INSTALL. 6.WHEN I COMPLETED INSTALLING THE SUN SHADE, I NOTICED THE CAR WAS MOVING BACKWARDS AT LESS THAN 5 MPH. 7.I TRIED REPEATEDLY TO STOP THE CAR BY PRESSING ON THE BRAKE AND SLAMMING ON THE BRAKE. 8.WHAT WAS HAPPENING MADE NO SENSE TO ME; IT WAS SURREAL. WHY WAS THE CAR MOVING BACKWARDS AND WHY COULDN'T I STOP THE CAR? 9.THE CAR STOPPED WHEN IT HIT A PARKING LOT LIGHT POLE ON MY LEFT REAR AND THE LEFT FRONT OF A TOYOTA ON MY RIGHT REAR. 10.THE CAR IS EQUIPPED WITH EVERY PRE SENSE, DRIVER ASSISTANCE, AND COLLISION AVOIDANCE SYSTEM AUDI OFFERS; HOWEVER, ALL SYSTEMS FAILED TO DETECT OR AVOID THE COLLISION. 11.THE ACCIDENT WAS CAUSED BY SOME WEIRD PROBLEM WITH MY 2018 AUDI Q5. THERE WAS NOTHING I COULD DO IN THE TIME I HAD WITHOUT THE BRAKES WORKING.
PURCHASED A 2018 AUDI Q5 IN JULY 2017. THE ENGINE LOST POWER OR ACCELERATION WHEN MAKING A TURN. TOOK IT TO THE DEALER 2 TIMES FOR THE SAME PROBLEM AND CANNOT REPRODUCE THE PROBLEM.
WHILE DRIVING DOWN THE EXPRESSWAY IN CHICAGO, TRANSMISSION, AND ALL SAFETY FEATURES COMPLETELY SHUT OFF. PRESSING ON ACCELERATOR HAD NO EFFECT, AND WITH LIMITED STEERING WAS ABLE TO PULL TO ROADSIDE BARELY MISSING HIGH-SPEED TRAFFIC. EXPRESSWAY ROADSIDE IS NARROW, SO WAS NEARLY HIT BY MANY CARS WHILE WAITING FOR TOW SERVICE. CAR WOULD NOT RESTART AND WITH FULL ELECTRONIC TRANSMISSION, NO ABILITY TO PUT INTO NEUTRAL. AUDI ROADSIDE ASSISTANCE DID NOT PROVIDE TIMELY TOW SERVICE. EXTREMELY DANGEROUS AND UNSAFE.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
