2025 Audi Q5 owner complaints

On December 22nd i got into the vehicle and a few errors popped up which consisted of “loose wheel warning malfunction” “brakes: limited functionality drive with causation” “active front assist and emergency assist unavailable”. I called the nearest dealer and was told it’s ok to drive it’s just a software glitch and if i don’t feel comfortable driving i should take it to the dealer and come back tomorrow for a loaner since service was closed already. So i proceeded to drive home, about 10 minutes into the drive a warning for the coolant came up so i pulled off into a parking lot and as i went to park another warning came up saying coolant too high turn off vehicle and as i was approaching the parking spot the car started to overheat and smoke. This is a BRAND new car with BARELY 1000 mil

Brand new car, needed a major software upgrade, for engine code, no heat , safety system flashing. It’s going back to the dealer today , for faulty gps and limited camera view for speed signs. The car has major software issues

This vehicle Misrecognizes intersections on two lane highways and causes the vehicle to unexpectedly slam on its brakes without warning in anticipation of an intersection that either does not exist or where my vehicle has the entire right way. this behavior has persisted since the date of purchase and has not been corrected at all. Audi has confirmed that the vehicle is operating as designed however, I have personally almost had two major traffic accidents when this system engaged in the process of overtaking a vehicle, slamming the brakes and almost causing a accident where he and I was rear ended. This is not a vehicle. I would let a child learn how to drive in.

Two weeks after purchase, experienced multiple, random driver assistance failures. After attempting to repair issue once unsuccessfully, The dealership was unable to provide a second service appointment for two and a half months. Was explained all 2025 Audis were having issues, so couldn’t get car in any sooner. Before that second scheduled service appointment and while driving in traffic, the brakes failed.

The contact owns a 2025 Audi Q5. The contact stated while driving at undisclosed speed on three occasions, the contact noticed that there was an abnormal knocking sound coming from the dashboard. The vehicle was taken to the dealer to be diagnosed, but the cause of the failure could not be determined. The vehicle remained at the dealer unrepaired. The manufacturer was not notified of the failure. The failure mileage was approximately 10.

The NEW vehicle keeps showing a warning light on the dash saying that the rear wheel bolts are loose two accidents have occurred in a 60 day period, the vehicle has been in for service multiple times and Audi has not found a fix for the safety light warning or found the loose bolts or suspension break issues. The have ignored a vehicle defect notice sent and lawyered up as soon as I said the vehicle was a lemon.

Brake Electronics Control Unit Failure (DTC U041800): Logged active diagnostic code U041800 (implausible signal in address 812C). Dealership records confirm no permanent remedy exists, with software patches delayed into Q3 2026, leaving active braking and electronic system faults unaddressed. Electrical Grid Collapse & Parasitic Battery Drain: Vehicle experienced exterior lights activating independently during sleep mode and cyclical 300mA to 2.0A parasitic draws. Required warranty replacement of the Central Electrical Control Module (J519), Low Voltage Power Distributor Module (J1282), and primary 12V battery (RO #AUCS214055).

On XXX at approximately 5:00 PM, my 2025 Audi Q5 (VIN: [XXX]) initiated an unprovoked forward collision warning and emergency braking intervention while I was traveling at approximately 57–58 mph on [XXX]. Road conditions were clear and dry. Weather was sunny. Adaptive Cruise Control was not activated. I was the sole occupant of the vehicle. A vehicle was making a lawful turn onto the roadway from a T-intersection. There was substantial distance between my vehicle and the turning vehicle. No collision risk existed and no evasive action was required. Despite this, the vehicle's forward collision system overrode my control and initiated emergency braking without cause. As a result of the sudden braking and the force of the seatbelt restraint during the event, I sustained abdominal pain an

I bought this car in 12/2025. After putting approximately 60 miles on the car, the onboard computer would not save the inputted data. Took back to dealership and update performed. Upon returning the car for this work, the adaptive cruise control would shut itself off on the way to the dealer. They could not replicate this issue. Since having the car for about 6 months the car has been in to the dealer approximately 7 times all for different warning lights including having the module needing to be replaced that controlled the A/C. The most recent problem is the vehicle locking up its brakes and rapidly fastening down on the seatbelt while driving stating a red danger message that flashes on the informatic screen and then disappears but will not show up on the MMI screen. This has happened t

May 30, 2026 - Latching part of rear door lock broken. Had 3 grandchildren in the car at the time. Door would not latch. October 15, 2026 - Park gear would not work properly. Put in park and car would still roll. Hill-hold function also not working. March 24, April 8, August 7 - Front console lights up with warning lights for no reason. Dangerous as you don't know what is working and what is not. Forced us to have car out of commission for over 30 days since purchase on March 6, 2026

On October 14, 2026, while driving my 2025 Audi Q5 on a busy freeway at approximately 57 mph, the vehicle suddenly activated emergency braking and rapidly slowed/stopped without warning. At the same time, the seat belt tightened extremely forcefully around my body, restricting my movement and making it difficult to breathe. The instrument cluster then displayed “Emergency assist: canceled.” I believe the malfunction involved the vehicle’s emergency/driver-assistance braking system and restraint system. The vehicle is available for inspection upon request. The sudden braking created an immediate risk of a serious rear-end collision because the vehicle unexpectedly slowed/stopped in freeway traffic. I was also physically restrained by the seat belt during the event and unable to move normall

The lane keeping assistance system was engaged as we were traveling at approximately 55 mph and started around a right hand curve. The system aggressively jerked the car to the left and with the wheels on the rumble strip associated with the center double yellow lines. There was traffic flowing the opposite direction and we would have been head to head with an oncoming truck had the driver not stopped the car. The car has been to the dealer, they can not reproduce any issues with the system and have asked that video be taken the next time this happens which is not feasible nor safe. I have not driven with the lane keeping assistance on since this incident, this was not the first time that I had issues with it trying to turn the car out of a lane, and I do not feel comfortable with it e

I moved into a parking spot and pushed the brakes to stop but the car accelerated and hit a tree. However when the police drove the car out of the parking spot the brakes were working properly.

While driving home from the dealership on Route 65 at approximately 45 MPH, the vehicle suddenly and forcefully applied the brakes without warning. My husband and I are experiencing symptoms of whiplash including back and neck pain. There were no vehicles, pedestrians, or obstacles nearby that would have triggered this response. This was a scary experience, and I am concerned it could happen again in traffic or at higher speeds. This incident presents a serious safety hazard to me, my passengers, and others on the road. The auto was purchased one week ago. Had it in for service. According to the service summary, the Driver Assist System had a coding error, and a hard reset of the module was performed. Unfortunately, after the braking incident, upon arriving home and restarting the vehicle,

2025 Audi Q5 S Line (VIN [XXX]). Surrendered under binding repurchase order via BBB AUTO LINE Case #[XXX] (VA Lemon Law) due to uncorrected factory defects. Odometer locked at 855 miles. 1. POWERTRAIN FLUID DEFECT & SHIFT FAILURE: Delivered new (23 miles) with transmission critically low on hydraulic fluid. Caused gear actuator failures, DTCs P187C00, P086900, P270800, and a 20-minute failure to engage "Park" (Repair Order #[XXX]). Failure to engage Park creates an immediate unintended rollaway and collision hazard (FMVSS 102/114). The dealer had to add fluid and perform 10 consecutive sensor calibrations to restore basic operation. 2. ELECTRICAL SYSTEM COLLAPSE & LIGHTING HAZARD: The vehicle suffered systemic bus communication drops, gateway control module crashes, and uncommanded exter

The car floods with excess fuel after idling for a short period of time resulting in multiple misfires and violent vibration. The car will not restart and will need to be towed. In traffic jams, the car can fail stranding motorists and creating a very unsafe situation. The problem has been verified by the dealership. Apparently, it is a known issue with the new Audi Q5 and they do not have a viable solution. They said to put the car in neutral and rev the engine to try and burn excess fuel. However, once the misfires start, it’s probably too late. I have pictures of the warning lights and the service reports. The car is 2 weeks old and has been back to the shop twice ( towed once) for a total of 5 days.

The safety suite is non-functional and fails to warn the driver of oncoming

I bought a late model Audi Q5 2025 late February 2026. the one I bought was a loaner with 8K miles on it, list 60k, paid 48K for it. late April, we were in the mountains of western NC and were on a windy 2 lane mountain road after midnight with no cell service and nowhere to pull off. 7 warning lights came on, the most concerning was to immediately pull over and shut off the engine. We could not do this. The steering wheel was shaking and the climate systems shut off. All ABS were non functional. We drove the last half hour to the house, put the car in the garage and figured it would need to be towed the next day. The next morning, I turned it on and all was cleared out. I took it to the dealer when back in SC, but they could not find anything. it is now mid October, it has happened 4

Mileage at time of incident: Approximately 4,000 miles Date of incident: XXX Location: [XXX] Incident description: My vehicle was in neutral while going through an automatic car wash, as instructed. When the exit signal indicated it was clear to proceed, with my foot on the brake, I shifted into drive. The vehicle accelerated on its own, without corresponding accelerator pedal input, and struck the building adjacent to the car wash. The vehicle did not exit the building on its own, so I shifted into reverse. The vehicle again accelerated on its own and struck a structural beam. I applied continuous pressure to the brake pedal throughout the incident. The vehicle did not respond immediately, but the brakes eventually engaged and brought the vehicle to a stop. The vehicle's rear obstacle-det
