XT5
Overall
Mixed sentiment with a clear generational divide. The vehicle is consistently praised for its comfortable ride, quiet interior, spacious cabin, and perceived value when purchased used at a significant discount from MSRP. Long-term owners express strong satisfaction with the vehicle's practicality and overall driving experience when properly maintained.

- ⚠Outdated/unreliable infotainment system (CUE): Screen freezes, goes black while driving, unresponsive touch controls, Bluetooth/Apple CarPlay connectivity issues causing audio to only play from front speakers at low quality.
