What owners say
QX30
Overall
Mixed to negative sentiment overall. The vehicle is praised by some owners for its attractive design, sporty driving dynamics, good fuel economy from the turbocharged four-cylinder engine, and high-quality interior materials, especially when purchased as a used value proposition. However, a very strong and recurrent theme across owner discussions is significant concern over electrical and software glitches, which manifest in numerous, often dangerous, ways.
Best version to buy
Insufficient owner data available to designate a specific trim or model year as "best." Owner discussions reference various model years (2017-2019) and trims (Sport, AWD) without a clear consensus on a preferred version. The fundamental platform and powertrain are consistent across the model run.
Known issues
- ⚠Electrical and software glitches: includes dashboard randomly resetting while driving (causing car to shift to neutral and steering to lock), key fob not detected, remote start failure, infotainment screen blackouts, malfunctioning driver…
- ⚠Expensive maintenance and repair costs: parts and labor are costly because the vehicle shares many components with Mercedes-Benz; repairs like a power steering pump or engine temperature control module can cost thousands of dollars.
- ⚠Transmission issues in cold weather: harsh shifting or "dropping hard" into first gear when the transmission is cold. Frequency: recurrent.
