Rear Motor Cable Corrosion ("Cablegate")

Serious

On AWD hybrid models, the high-voltage cable connector to the rear motor is prone to severe corrosion from road salt and moisture. If it fails, the car may lose AWD capability and display a hybrid system fault.

Symptoms: Hybrid system warning lights, Loss of AWD functionality...

Est. repair cost: £3,000–£5,000

Power Tailgate Strut or Spindle Failure

Moderate

The motorised tailgate can become slow, jerky, or fail to latch properly as the powered struts and spindle mechanisms wear with age.

Symptoms: Tailgate stops part-way, Beeping tailgate warning...

Est. repair cost: £450–£1,000

Front Lower Arm Bush Wear

Moderate

The RX is heavy, and its front lower-arm bushes can soften or tear, leading to vague steering, inner tyre wear, and a dull thump over poor surfaces.

Symptoms: Clonk from the front suspension, Steering feels loose on motorways...

Est. repair cost: £350–£700

Rear Brake Disc and Caliper Corrosion

Minor

Because the hybrid system handles so much of the slowing, the rear mechanical brakes can corrode and bind if the car mainly does gentle town driving.

Symptoms: Squeal or grinding from the rear, Pitted rear discs...

Est. repair cost: £250–£500

Buying Tips for the 2019–2022 Lexus RX (AL20)

  • ✓Inspect the rear discs and calipers carefully because hybrids that do lots of short trips can carry heavy corrosion on the back brakes.
  • ✓Operate the power tailgate several times and listen for groaning struts or a tailgate that hesitates near the top of its travel.
  • ✓Try the Remote Touch controller and every climate/audio function, as laggy screens and unresponsive inputs are frustrating and expensive to sort properly.
