The Jeep Wrangler often faces specific issues during its MOT tests, with common failures including suspension problems, brake system faults, and emissions issues. Addressing these concerns can vary in cost, but understanding them can help you prepare for your MOT and keep your vehicle roadworthy.

Suspension Issues

One of the most frequent reasons for MOT failures in the Jeep Wrangler is suspension problems. This can include worn shock absorbers, damaged springs, or issues with the suspension geometry. These components are crucial for maintaining vehicle stability and comfort.

Regular checks can help identify these issues before they lead to an MOT failure.

Brake System Failures

Brake system failures are another common MOT failure point for the Jeep Wrangler. This can involve worn brake pads, damaged discs, or issues with the brake lines. Given the importance of brakes for safety, any problems in this area are taken seriously during an MOT.

Regular maintenance can help prevent these failures.

Emissions Problems

Emissions issues are increasingly scrutinised during MOT tests, and the Jeep Wrangler is no exception. Problems can arise from a faulty catalytic converter, issues with the exhaust system, or even engine management faults. These failures can lead to a vehicle being deemed non-compliant with environmental standards.

Keeping an eye on warning lights and having regular checks can help mitigate these risks.

Tyre Condition

Tyres are a critical component of any vehicle and are a common failure point during MOT tests. For the Jeep Wrangler, issues can arise from uneven wear, insufficient tread depth, or damage to the sidewalls. Proper tyre maintenance is essential for both safety and performance.

If multiple tyres need replacing, the costs can quickly add up. Regularly checking tyre pressure and tread depth can help ensure compliance and safety on the road.

Lighting and Electrical Failures

Lighting and electrical failures are another area where the Jeep Wrangler may struggle during an MOT. This can include issues with headlights, brake lights, indicators, or dashboard warning lights. Proper functioning of these systems is crucial for safety and visibility.

Regularly checking all lights and addressing any warning lights on the dashboard can help avoid MOT failures related to electrical systems.

Bodywork and Structural Integrity

Finally, bodywork and structural integrity can also lead to MOT failures for the Jeep Wrangler. Rust, corrosion, or damage to the chassis can raise concerns about the vehicle’s safety and roadworthiness. Addressing these issues promptly is essential for maintaining compliance.

Regular inspections can help identify these issues early and prevent costly repairs later.

Jeep Wrangler recall record

33 recalls have been issued for the Jeep Wrangler, between 1995 and 2026.

  1. Passenger airbag inflator

    R/2026/130

    Issued 20 March 2026

    In the event that the airbag is activated excessive internal pressure may cause the inflator body to rupture and metal fragments may pass through the cushion material causing injury to the vehicle occupants and / or in worst cases a fatality. The concern is caused by moisture in the air getting past faulty seals and being absorbed by the pyrotechnic biscuits in the inflator. As a result it is more likely to occur sooner in areas of high humidity and high temperature difference.

    Remedy:Recall the vehicles that are likely to be affected and replace the passenger front air bag module which includes the inflator.

    Affects cars built May 2008 to Jul 2012

  2. Passenger airbag inflator

    R/2026/135

    Issued 20 March 2026

    Passenger air bag may deploy incorrectly if activated.

    Remedy:Replace the passenger air bag inflator.

    Affects cars built Aug 2009 to Dec 2016

  3. 2018-2022 Jeep Wrangler Check Engine Malfunction Indicator Lamp Incorrect operation and warning

    R/2026/060

    Issued 2 March 2026

    On affected vehicles the Malfunction Indicator Lamp (MIL) may not function as intended in the Instrument Panel Cluster (IPC). This condition will not affect emissions. However in the event of an emission issue that would require illumination of the MIL the driver may not be alerted due to the MIL not illuminating.

    Remedy:Install updated software.

    Affects cars built Aug 2017 to Jun 2022

  4. 2020-2025 Jeep Wrangler and 2022-2026 Jeep Grand Cherokee PHEV vehicles. High voltage battery.

    R/2026/029

    Issued 16 February 2026

    On affected vehicles the High Voltage (HV) battery may have been built with a battery pack which contains cells which are susceptible to separator damage which combined with other complex interactions within the cells may lead to a vehicle fire.

    Remedy:Reprogram the battery pack control module with modified software and check and if necessary replace the HV Battery.

    Affects cars built Jul 2020 to Dec 2024
