Recent owner complaints
Reports submitted to NHTSA, shown in the owner's own words
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.

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.
