Open the full vehicle complaint log (all categories)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.
