The Lexus RX is a popular luxury SUV, but like any vehicle, it can encounter issues during its MOT. Common failures often include problems with the brakes, suspension, and emissions. Fixing these issues can vary in cost, but understanding them can help you prepare for your next MOT.

Brake System Issues

Brakes are one of the most critical safety components of any vehicle, and the Lexus RX is no exception. Common MOT failures related to the braking system include worn brake pads, damaged discs, and issues with brake lines.

Regular maintenance can help prevent these issues, ensuring your brakes remain in good condition.

Suspension Problems

The suspension system on the Lexus RX can be prone to wear and tear, especially if the vehicle has been driven on rough roads. Common MOT failures include worn shock absorbers, broken springs, and damaged bushings.

Keeping an eye on your suspension and addressing any issues early can save you money in the long run.

Emissions Failures

Emissions-related failures are increasingly common in modern vehicles, including the Lexus RX. Issues can arise from faulty oxygen sensors, catalytic converters, or exhaust leaks.

Regular servicing can help keep your emissions system in check and avoid costly repairs.

Tyre Condition and Tread Depth

Tyres are essential for safe driving, and their condition is a common MOT failure point for the Lexus RX. Inspectors will check the tread depth and overall condition of the tyres, looking for signs of wear or damage.

If your tyres are found to be below the legal tread depth of 1.6mm, you will need to replace them. Regularly checking your tyre pressure and tread depth can help you avoid unexpected replacements.

Lighting and Electrical Systems

The lighting and electrical systems in the Lexus RX are vital for safe driving, and failures in this area are common during MOT tests. Issues can include blown bulbs, faulty wiring, or malfunctioning indicators.

Regularly checking your lights and electrical systems can help ensure they are functioning correctly before your MOT.

Windshield and Wiper Issues

Visibility is crucial for safe driving, making the condition of the windshield and wipers an important aspect of the MOT test. Common failures include cracks in the windshield and worn wiper blades.

Regular maintenance of your windshield and wipers can enhance visibility and prevent MOT failures.

Lexus RX recall record

6 recalls have been issued for the Lexus RX, between 2011 and 2025.

  1. Parking Assist ECU reprogram on multiple models

    R/2025/467

    Issued 1 December 2025

    For certain vehicles equipped with a Parking Assist ECU a component of the Panoramic View Monitor (PVM) system that displays the rear view image the software may cause the rear view image to freeze or not display

    Remedy:Reprogram the parking assist ECU.

    Affects cars built Apr 2022 to Sept 2025

  2. Combination Meter Reprogramming on Multiple Models (Lexus)

    R/2025/275

    Issued 24 November 2025

    For certain vehicles equipped with the combination meter system (where various information is displayed) that due to an improper programming of the combination meter unnecessarily repetitive data is written to a memory device. This may cause the memory device to deteriorate and the monitor to not display during the meter at start up and remain in this state permanently.

    Remedy:Reprogram or replace the combination meter.

    Affects cars built Jun 2024 to Jun 2024

  3. Due to the software programming for the DCM memory capacity there is a possibility that the DCM may not complete the shutdown process within a specific period of time when the ignition is turned off causing the DCM to not restart at the next ignition cycle and making the e-Call function unavailable.

    R/2023/280

    Issued 12 October 2023

    On affected vehicles there is a possibility that the DCM may not complete the shutdown process within a specific period of time when the ignition is turned off causing the DCM to not restart at the next ignition cycle and making the e-Call function unavailable. As a result the vehicles do not comply with relevant regulations.

    Remedy:The software of the DCM (Data Communication Module) will be updated via an Over the Air (OTA) wireless update.

    Affects cars built Feb 2023 to Jun 2023

  4. VEHICLE COULD SUDDENLY STOP

    R/2013/104

    Issued 16 October 2013

    It is possible that due to variations in the build specification of the Intelligent Power Module (IPM) which includes the Insluted-Gate Bipolar Transistors (IGBT's) the lead-based solder could be affected by abnormally higher operating temperatures. This could result in a degrading of the solder and eventually heat damage to the IGBT's. If this occurs then warning lights on the instrument panel will illuminate. However if the driver fails to heed these warnings or the main power supply fuse blows then the vehicle could stop without warning.

    Remedy:Recall all the affected vehicles and replace the IPM unit with a upgraded unit.

    Affects cars built Apr 2006 to Dec 2008
