2021 Lexus nx 300 common problems

Owners have filed 17 complaints with NHTSA. These are the most-reported areas in a sample of the most recent — and what to check before you buy.

Engine
Listen for knocks or ticking, check for leaks and blue/white exhaust smoke, and make sure it doesn't overheat. No check-engine light should be on.
Visibility
Test wipers, washers, defrosters and all mirrors. Check the windshield for cracks and any camera/sensor for fogging or faults.
Fuel/propulsion System
Check for fuel or battery warnings, hard starts and stalling. On a hybrid/EV, confirm charging and range behave normally.
Electrical System
Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
Service Brakes
Brakes should feel firm and quiet — no grinding, pulsing or pulling. Check for an ABS light and uneven pad/rotor wear.
Tires
Check tread depth, the DOT age date, and that all four tires match with even wear. Look for bulges or cracks.
