There are 2 owner-reported fuel system complaints for the 2019 Audi Q3in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Vehicle stalls even while actively engaged in driving. Audi diagnosed performing as designed and advised nothing that they can do until diagnosed as “not performing as designed”. Poses imminent crash issue as vehicle will stall at any time. Please investigate. I am terrified to drive the car from place to place.
Vehicle fuel pump fails intermittently even while actively engaged in driving. Engine stalled while driving putting me at risk for an accident. Issue was hard to diagnose because the fault would clear after an episode and reappear 300-400 miles after being driven again. Check engine light appears and then after allowing car to sit for a few hours, the car will start again. Sometimes the check engine light remains, other times it goes away on its own. Vehicle was inspected by Audi Little Rock and was performing as designed but issued occurred again 4 days after pickup. Currently the high pressure fuel pump is being replaced to try and solve the problem but vehicle can be made available for inspection if this does not resolve the issue. Since it is intermittently failing, issue hasn’t been duplicated during inspection. Incident has occurred approx 8 times since purchased in Jan 2022.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
