There are 1 owner-reported engine complaints for the 2025 Audi Q5in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
When attempting to accelerate rapidly (I.e. passing gear) the engine immediately begins to lose power. Audi dealer investigated and determined it was “TURBO LAG”. This situation happened multiple times at different speeds. When trying to accelerate to pass another vehicle or to merge onto a freeway are the scariest and most dangerous instances. Taking your foot off the accelerator does allow the engine to regain speed. The salesman that we had experienced this on a test ride with me. In reading previous turbo problems with Audi/ Volkswagen vehicles, I’m concerned that this may become a safety issue. This also occurred with the loaner vehicle they gave me which was the same year and model.
