TL;DR

Lexus UX owners should be aware of common faults such as infotainment glitches, suspension noises, battery drain, brake pad wear, and air conditioning problems. Many issues can be fixed DIY, while others may require professional help, with repair costs ranging from £50 to £600 depending on the issue.

Infotainment System Glitches

The Lexus UX is known for having issues with its infotainment system, including unresponsive screens and software crashes. A software update can often fix these glitches. This is a DIY job if you’re comfortable with technology; otherwise, a garage can perform it for around £50 to £100.

Suspension Noises

Some owners report knocking or creaking noises from the suspension, particularly in models from 2019 to 2021. This is often due to worn bushes or shock absorbers. Replacing these parts can be a DIY task if you have the right tools. Parts cost around £100 to £200, while a garage may charge £200 to £400 for the job.

Battery Drain Issues

Battery drain is another common complaint, especially in models with advanced electronics. Checking for parasitic drain can be done at home with a multimeter. If the battery needs replacing, expect parts to cost around £100 to £150. A garage may charge £50 to £100 for labour.

Brake Pad Wear

Brake pads on the Lexus UX can wear down faster than expected, especially in city driving conditions. Replacing pads is a straightforward DIY task if you have basic mechanical skills. Parts typically cost between £50 and £100, while a garage may charge £150 to £250 for the full job.

Air Conditioning Problems

Some owners have reported issues with the air conditioning system, particularly a lack of cold air. This can often be fixed by recharging the system or replacing a faulty compressor. A recharge can be DIY for around £50, but a compressor replacement is best left to a garage, costing between £300 and £600.
