2019 Lexus LS (Mk5)

LS Mk5 models fitted with optional air suspension can develop leaking struts as the rubber bladders perish with age and exposure to road salt. Slow air leaks force the compressor to run continuously, eventually burning out the motor. The car sits low overnight and the ride becomes harsh and bouncy.

Symptoms: One corner sitting visibly low after parking overnight, Air compressor running for prolonged periods...

Est. repair cost: £1,000–£1,600 per strut

The LS 500h's compact 12V auxiliary battery can be drained by the car's connected systems and telematics if the vehicle is left unused for as little as a week.

Symptoms: Car unresponsive to key fob, Multiple warning lights on startup...

Est. repair cost: £200–£300

Symptoms: Growling or humming noise that increases with speed, Noise that changes when cornering left or right...

Est. repair cost: £250–£500 per side

Symptoms: Loud humming from the tyres at motorway speeds, Vibration through the steering wheel...

Est. repair cost: £300 per tyre

Symptoms: Cursor jumps or fails to register on the touchpad, Menu navigation is slow and unintuitive...

Est. repair cost: £200–£700
