Top issues to watch for

The most serious Chrysler 300 problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.

Dangerous
Front suspension ball joint wear (LX)
LX2006–201540k–150k miles
The front suspension ball joints show excessive wear at 7.9x the fleet average rate according to MOT data. These joints connect the steering knuckle to the control arms and their failure can cause sudden loss of steering control. The problem affects all mileage bands from 40,000 miles upward and appears to be getting worse over time, suggesting a design or material weakness.
What happens if ignoredA failed ball joint can separate completely, causing immediate loss of steering control and wheel collapse. This represents a serious safety risk. Even worn joints affect handling and cause rapid tyre wear.

Dangerous
Wheel bearing failure (LX)
LX2006–201560k–150k miles
Wheel bearings fail at 7.9x the fleet average rate, particularly from 60,000 miles onwards. A failed wheel bearing can cause wheel wobble, steering pull, and in extreme cases, wheel detachment. The relatively heavy kerb weight of the 300 may accelerate bearing wear compared to lighter vehicles.
What happens if ignoredComplete bearing failure can cause wheel detachment and loss of vehicle control. Even partial failure causes dangerous handling characteristics, brake judder, and rapid tyre wear. This is a safety-critical component.

Major
Parking brake cable seizure and adjuster failure (LX)
LX2006–201540k–150k miles
The handbrake system uses cables and adjusters that are prone to corrosion and seizure, particularly in UK conditions. MOT data shows this model fails handbrake efficiency tests at up to 17.7x the national fleet average, with the problem worsening over time. The cables can seize partially or completely, leading to uneven braking or total handbrake failure. This is a persistent design weakness affecting the entire model generation.
What happens if ignoredFailed MOT on brake efficiency test. A seized handbrake can cause brake drag, premature brake wear, and potential wheel bearing damage. In extreme cases, complete handbrake failure creates a safety risk on hills and during parking.

Major
Brake caliper binding and disc damage (LX)
LX2006–201540k–150k miles
MOT data shows brake binding at 5.0x fleet average and brake disc damage at 2.1x fleet average. The brake calipers are prone to seizure, causing constant brake pad contact with discs. This leads to overheating, warped or cracked discs, and premature brake component wear. The heavy weight of the 300 exacerbates brake system stress.
What happens if ignoredBinding brakes cause rapid pad and disc wear, reduced fuel economy, and potential brake fade from overheating. Severely warped discs can cause loss of braking effectiveness and dangerous handling characteristics.
