Catastrophic depreciation and high repair costs — vehicles lose value rapidly and require very expensive repairs post-100,000 miles, with parts being costly and hard to find. Frequency: very frequent.
Aging electrical and sensor failures — numerous sensors fail causing stalling, rough running, and check engine lights; window regulators, key fobs, and HVAC system components are problematic. Frequency: very frequent.
Power steering system failures — pumps, racks, and high-pressure lines leak and fail, causing fluid expulsion from the reservoir and noisy operation. Frequency: recurrent.
Fuel system problems — fuel pumps fail and are discontinued, fuel level sensors fail, fuel lines and tanks rust/corrode in older models. Frequency: recurrent.
Poor fuel economy — V8 engines require premium fuel and achieve low real-world MPG (examples of 8 MPG and "gas guzzler" are cited), which is a noted ownership cost. Frequency: recurrent.
Owner insights cover all generations of the Q45.
