Most Common Lexus UX Faults & Repair Costs
12V Battery Drain
The most common complaint on UX owner forums; the 12V battery is small and can be drained by the car's connected systems.
Weak cranking, "Check Hybrid System" warning caused by low voltage, Keyless entry not working
- Ask if the 12V battery has been replaced with a higher-capacity aftermarket unit (e.g. Yuasa)
Excessive Road Noise (Run-Flats)
Models on 18-inch wheels with run-flat tyres can suffer from significant road roar on coarse UK motorways.
Loud humming from tyres, Harsh ride over expansion joints
- Check tyre tread and brand
- Listen for road noise at 60mph+
Buying a used Lexus UX? Always check for hidden finance and write-off history.
Mechanical problems are only half the battle. Over 1 in 3 UK used cars checked have unpaid finance or accident write-off records that could cause you to lose the car or thousands in value.
