2025 Audi Q5 Complaints

Brake Electronics Control Unit Failure (DTC U041800): Logged active diagnostic code U041800 (implausible signal in address 812C).

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). Powertrain & Transmission Engagement Failures: Experienced Check Engine Light cycling and a total failure to engage "Park" for 20 minutes.

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-detection and automatic braking sensors, which normally engage under similar low-speed reversing conditions, did not activate at any point during this incident. The airbags also did not deploy after the...

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 and lower back pain that began immediately following the incident and persisted thereafter. This incident did not occur in isolation. Prior to this event, the vehicle had already exhibited a documented...

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 twice in the last 10 days. Upon the first visit I was told that Audi has been having a lot of problems with the 2025 Q5 because of the computer. The car is currently back in the shop for continued safe...
