RXbuyer's guide

The AL20 RX sells fast and holds value well, which means sellers have little pressure to disclose problems — and buyers who skip the checks pay for it later. Transmission shudder that only shows up fully warm, coolant loss that points to a water pump on its way out, and AWD vibration that gets blamed on tyres are the patterns that catch buyers off guard most often. This guide gives you the field checks to run before the money changes hands.

This guide covers ten documented issues: transmission shudder or harsh shift, coolant leak or overheating, AWD/transfer case vibration, infotainment/camera electrical faults, suspension knocks and tyre wear, brake corrosion or seized caliper, oil leak or consumption, water leak or poor accident repair, ADAS/radar calibration fault, and recall/campaign status. Each fault has a field check and a real repair-cost range.

A well-serviced AL20 RX is one of the more reliable choices in the used luxury SUV market. The risk is not the platform — it is the seller who has skipped services and cleared codes before listing. Verify the service history, run the diagnostic scan, and check the tyres match before you decide.
