MOT failure rates

Chrysler 300C MOT failure rates: what to expect

What fails on a Chrysler 300C at MOT, how often, and what each fix typically costs.

Updated 4th September 2026 DVSA data: Across 431 recorded MOT tests, 29.9% failed.

The Chrysler 300C often faces MOT failures primarily due to issues with its suspension, brakes, and electrical systems. Common problems include worn suspension components, brake performance issues, and electrical faults, with repair costs varying based on the severity of the issue and labour rates.

Suspension Issues

One of the most frequent reasons for MOT failures on the Chrysler 300C is related to its suspension system. Worn or damaged components such as shock absorbers, control arms, and bushings can lead to a failed MOT. The DVSA MOT data indicates that suspension-related failures are common across various vehicle models, including the 300C.

Regular checks and maintenance can help mitigate these costs.

Brake System Failures

Brakes are critical for safety, and any deficiencies can lead to an automatic MOT failure. The Chrysler 300C may experience issues with brake pads, discs, or the hydraulic system. Problems such as uneven wear on brake pads or worn brake discs are often reported in MOT tests.

Regular brake inspections can help identify issues before they lead to an MOT failure.

Electrical System Problems

Electrical faults are another common reason for MOT failures in the Chrysler 300C. Issues with lights, indicators, and the battery can cause significant problems during the MOT test. The vehicle’s complex electrical system can sometimes lead to intermittent faults that are difficult to diagnose.

Fixing electrical issues can vary widely in cost. Regular checks of the electrical system, including lighting and battery health, can prevent unexpected failures during the MOT.

Exhaust Emissions

The Chrysler 300C is also subject to emissions testing during the MOT. If the vehicle fails to meet the required emissions standards, it will not pass the test. Common issues include a faulty catalytic converter or exhaust leaks, which can lead to increased emissions.

Regular maintenance of the exhaust system can help ensure compliance with emissions standards.

Tyre Condition

Tyres are a critical component of vehicle safety and are closely inspected during the MOT. The Chrysler 300C may fail if the tyres are worn beyond the legal limit or if there are issues with alignment. Tyre condition is a frequent failure point across many vehicles.

Regular tyre checks and rotations can help prolong tyre life and ensure safety.

Bodywork and Structural Integrity

Finally, the bodywork and structural integrity of the Chrysler 300C can also lead to MOT failures. Rust, corrosion, or damage to structural components can be serious issues that need addressing. The MOT test includes checks for any significant deterioration that could affect safety.

Repair costs for bodywork can vary significantly based on the extent of the damage. Regular inspections and prompt repairs can help maintain the vehicle’s integrity and safety on the road.

Chrysler 300C recall record

8 recalls have been issued for the Chrysler 300C, between 2008 and 2026.

  1. Driver airbag inflator

    R/2026/129

    Issued 20 March 2026

    The driver airbag inflator housing may rupture due to excessive internal pressure during normal airbag deployment events. This condition is more likely to occur if the vehicle has been exposed to high levels of absolute humidity for extended periods of time.

    Remedy:Replace the driver airbag inflator.

    Affects cars built Feb 2004 to Oct 2010

  2. Passenger airbag inflator

    R/2026/131

    Issued 20 March 2026

    The front passenger airbag inflator (PAB) may contain propellant that could possibly degrade over a period of time. This may cause metal fragments to pass through the air bag and into the vehicle interior at high speed which may result in injury to vehicle occupants in the event of a deployment event.

    Remedy:On affected vehicles replace the inflator assembly.

    Affects cars built Apr 2008 to Jul 2013

  3. The Tyre Pressure Monitor System (TPMS) sensors may prematurely discharge its battery making the TPMS sensor inoperative

    R/2022/269

    Issued 7 October 2022

    The Tyre Pressure Monitor System (TPMS) sensors may prematurely discharge its battery making the TPMS sensor inoperative.

    Remedy:Inspect and if necessary replace the Tyre Pressure Monitor System (TPMS) sensors.�

    Affects cars built Sept 2021 to Jun 2022

  4. Passenger airbag inflator

    R/2019/198

    Issued 26 July 2019

    Passenger air bag may deploy incorrectly if activated.

    Remedy:Replace the passenger air bag inflator.

    Affects cars built Aug 2009 to Sept 2015
