The Land Rover Defender is a popular choice among off-road enthusiasts, but it is not without its issues when it comes to the MOT test. Common failures include suspension problems, emissions issues, and corrosion. Addressing these problems can vary in cost, but understanding them can help you prepare for your next MOT.

Suspension Components

One of the most frequent reasons for MOT failures in the Land Rover Defender is related to suspension components. Issues often arise with the shock absorbers and bushes, which can wear out over time due to the vehicle’s off-road capabilities.

Regular checks and maintenance can help prolong the life of these components.

Emissions and Exhaust System

Emissions failures are another common issue for the Defender, particularly in older models. Problems can stem from a malfunctioning catalytic converter or issues with the exhaust system, which can lead to increased emissions and a failed MOT.

Regular servicing and timely replacement of exhaust components can help mitigate these issues and keep emissions within acceptable limits.

Braking System

The braking system is crucial for safety and is a common area of concern during the MOT. Defenders often experience issues with brake pads, discs, and even brake lines, which can lead to a failure if not addressed.

Regular inspection of the braking system can help catch these issues early.

Bodywork and Corrosion

Corrosion is a significant concern for Land Rover Defenders, particularly in older models. The chassis and body panels are prone to rust, which can lead to MOT failures if not properly managed.

Regular cleaning and treatment of vulnerable areas can help prevent rust from becoming a major issue, ensuring your Defender remains in good condition.

Lights and Electrical Systems

Issues with lights and electrical systems are common MOT failures for the Defender. Problems can include blown bulbs, faulty wiring, or malfunctioning indicators, which can easily lead to a failed test.

Regular checks of all lights and electrical systems can help ensure compliance with MOT standards.

Tyres and Wheel Alignment

Tyres are another critical area that can lead to MOT failures. Common issues include insufficient tread depth, uneven wear, or damage to the sidewalls. Additionally, wheel alignment problems can affect handling and lead to premature tyre wear.

Regular tyre maintenance and checks can help ensure that your Defender remains roadworthy and safe.

Land Rover Defender recall record

31 recalls have been issued for the Land Rover Defender, between 2000 and 2026.

  1. AJ20-D6 Idler Pulley Clash

    R/2026/241

    Issued 26 June 2026

    A concern has been identified on certain AJ20-D6 engines where the Front End Auxiliary Drive (FEAD) belt idler pulley may over-rotate following a high torsion input and lead to a clash with and damage to the oil pressure and temperature sensor. A damaged oil pressure and temperature sensor can lead to an oil leak from the engine which can result in a slip hazard for following road users particularly two-wheeled vehicles.

    Remedy:Vehicles will have the Front-End Auxiliary Drive (FEAD) idler pulley replaced.

    Affects cars built Jun 2024 to Apr 2026

  2. Driver’s Airbag Potential Non-Deployment

    R/2026/245

    Issued 19 June 2026

    A concern has been identified where the connector to the driver’s airbag at the clockspring may experience fretting corrosion over time. This can lead to an increased resistance in the driver’s airbag circuit potentially resulting in the airbag failing to deploy when requested to do so. An airbag which fails to deploy as-intended will increase the risk of injury in the event of a crash.

    Remedy:Vehicles will have a protective lubricant gel applied to the driver’s airbag connector terminals.

    Affects cars built Apr 2019 to Jun 2026

  3. E-PACE F-PACE Defender Discovery Sport Range Rover Evoque and Range Rover Velar PHEV Traction Battery Fire Risk

    R/2025/553

    Issued 12 June 2026

    Vehicles have experienced thermal overload which may manifest in smoke or fire that may occur underneath the rear of the vehicle where the high voltage traction battery is located. The root cause is not yet known and investigations are continuing. A vehicle thermal overload condition such as fire or smoke can result in increased risk of occupant injury and/or injury to persons outside the vehicle as well as property damage.

    Remedy:Vehicles will be inspected by the retailer and as required at-risk battery packs will be replaced.

    Affects cars built Oct 2020 to Jan 2025

  4. Defender and Discovery 2026 Model Year Fuel Tank Wall Thickness

    R/2026/177

    Issued 12 June 2026

    A concern has been identified where the fuel tank wall thickness may be below design specification near the inlet check valve. A fuel tank with a thinner-than-designed wall may not perform adequately in the event of a crash leading to increased risk of fuel spillage and potentially fire.

    Remedy:Affected vehicles will have the fuel tank replaced.

    Affects cars built Jan 2026 to Jan 2026
