Top Lexus NX fixes every owner should know

TL;DR

Lexus NX owners should be aware of common faults such as infotainment glitches, suspension noise, battery drain, brake problems, and oil leaks. Understanding these issues and their fixes can save time and money on repairs, with costs ranging from £30 to £300 for parts and £60 to £120 per hour for garage labour.

Infotainment System Issues

Many Lexus NX models from 2014 to 2021 experience infotainment system glitches, including freezing screens and unresponsive controls. A software update may resolve the issue if you are comfortable with electronics. Otherwise, a garage may charge around £80 for a diagnostic and update.

Suspension Noise

Suspension noise is a frequent complaint in models from 2015 to 2020, often caused by worn bushings or struts. A DIYer can replace bushings for around £50, while strut replacement can cost about £150 in parts. Garage labour may add £100 to £150 to the total cost, and this fix can be temporary if the underlying cause is not addressed.

Battery Drain

Battery drain issues are common in Lexus NX models from 2016 to 2021, often due to a faulty alternator or parasitic draw from electronics. You can test the alternator at home with a multimeter. If replacement is needed, expect to pay around £200 for parts, with garage labour likely adding £80 to £120. Fixing the alternator is a permanent solution.

Brake Problems

Brakes can wear out, particularly on models from 2014 to 2019, with symptoms including squeaking or grinding noises. Replacing brake pads is a straightforward DIY job costing around £50 for parts. If rotors need replacing, that could add another £100. Garage labour for brake jobs typically ranges from £60 to £100, and this fix is generally long-lasting.

Oil Leaks

Oil leaks can occur in Lexus NX models from 2015 to 2020, often from the valve cover gasket. A DIY replacement of the gasket costs around £30. If you opt for a garage, expect to pay £100 to £150 for the job. This is usually a permanent fix, provided no other issues exist.
