Top issues to watch for
The most serious Chrysler Jeep 300 problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.
The Chrysler 300 diesel variants show excessive wear in steering ball joints, failing MOT tests at 30 times the fleet average rate. The heavy 3.0-litre diesel engine combined with the vehicle's weight creates high loads on front suspension components. Ball joint wear typically starts early due to inadequate dust boot protection and progresses to dangerous levels of play that affect steering precision and safety.
What happens if ignoredExcessive ball joint wear creates dangerous steering instability and can lead to complete joint separation, causing loss of steering control. The vehicle should not be driven with confirmed ball joint failure. Joint replacement typically requires wheel alignment afterwards.

The Chrysler 300 diesel variants show wheel bearing failure at 15.7 times the fleet average rate. The vehicle's substantial weight combined with the heavy diesel engine places high loads on wheel bearings. Front bearings typically fail first due to steering loads and braking forces. Bearing wear progresses from noise to excessive play and can result in wheel detachment if not addressed.
What happens if ignoredFailed wheel bearings can cause wheel detachment leading to loss of control and potential accident. Excessive bearing play affects ABS and ESP sensor operation. The vehicle should not be driven with confirmed bearing failure.

£200–£400
The Chrysler 300 diesel variants suffer from widespread parking brake system deterioration, with MOT data showing failure rates 35 times higher than the fleet average. The system uses rear disc-mounted parking brake shoes which corrode and seize due to limited use and moisture ingress. Cable adjustment mechanisms also corrode, leading to complete system failure. This affects both parking brake efficiency and one-sided operation, creating a safety risk on gradients.
What happens if ignoredComplete parking brake failure creates a safety risk when parking on gradients and will result in MOT failure. Cable corrosion can lead to seizure requiring complete cable replacement. Rear brake shoe replacement typically requires rear disc removal.
Independent garage
£300–£500
The Chrysler 300 diesel variants experience Electronic Stability Control system malfunctions at The ESP system relies on multiple wheel speed sensors, steering angle sensors, and lateral acceleration sensors which are prone to failure. Failed sensors cause the ESP malfunction warning light to illuminate and disable stability control functions, compromising safety in emergency manoeuvres.
What happens if ignoredESP system failure removes critical safety systems during emergency manoeuvres. The vehicle remains driveable but stability intervention is not available. Diagnosis typically requires fault code reading to identify which sensor has failed.
