American muscle meets Mercedes engineering, for pennies
The Chrysler 300C is an American full-size saloon that brought unapologetic brash styling and V8 muscle to the UK market. Sold from 2005 to 2015 before Chrysler withdrew from Europe, it attracted buyers wanting something dramatically different from the German executive saloon norm. Built on Mercedes E-Class underpinnings, it offers surprising mechanical quality beneath its imposing American exterior, and is now a genuine bargain on the used market.
We track 5 known issues across the Chrysler-Jeep 300 range, including 2 rated as safety-critical. Knowing which variants and configurations to approach with caution can save you from expensive surprises after purchase.

LX (2005–2010) — Petrol options included the 3.5 V6, 3.6 V6, 5.7 HEMI V8, 6.1 SRT-8 V8, with 3.0 CRD V6 on the diesel side. Our database flags 5 known issues on this generation, 2 of which are rated as safety-critical. The most significant concern is Steering ball joint wear (£200–£400 to address).
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.
Excessive 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.
During the test drive, check the steering for excessive play, vibration or pulling to one side. Listen for groaning or whining when turning the wheel at low speed. Power steering fluid level and condition should be checked on hydraulic systems.
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.
Failed 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.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
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.
Complete 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.
Check brake disc condition for lipping or scoring. Test braking at moderate speed for pulling to one side or vibration through the steering wheel. Review MOT advisories for brake-related items.
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.
ESP 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.
Check all electrical functions systematically: windows, mirrors, lights, infotainment, heated seats, air conditioning. Look for any warning lights on the dashboard. A diagnostic scan before purchase can reveal stored fault codes.
The Chrysler 300 diesel variants experience suspension joint dust cover deterioration at 12.9 times the fleet average rate. Rubber dust covers protecting ball joints, track rod ends, and CV joints perish due to age and contamination from road salt and debris. Split dust covers allow water and dirt ingress, accelerating wear of the protected joints and leading to premature failure of expensive suspension components.
Split dust covers lead to accelerated wear of expensive suspension joints. Early replacement of covers can prevent costly ball joint, CV joint, or track rod end failures. Neglected split covers typically result in joint replacement within 12-24 months.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.

Based on 23k real DVSA MOT tests, the Chrysler-Jeep 300 fails more often than average on several items. The biggest outlier is parking brake efficiency less than 50% of the r... at 82x the fleet average, followed by abs fault (68x).
When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full Chrysler-Jeep 300 MOT failure breakdown for data at every mileage point.
Routine servicing (oil and filter change every 10k miles) typically costs £80–£120 at an independent garage.
The bigger-ticket items to budget for include automatic transmission fluid (£200–£300).

The Chrysler-Jeep 300 has some well-documented weak points, including 2 safety-critical issues that demand careful checking. The right example, properly maintained, can still be a sound purchase — but cutting corners on the pre-purchase inspection is not advisable. For the first generation (2005-2010), later 2007-2010 models resolved the early electrical gremlins that plagued 2005-2006 cars. The second generation (2012-2015) is more refined with better interior quality and updated styling. The 3.0 V6 CRD diesel is the sensible UK choice; the 5.7 HEMI is for enthusiasts who accept the fuel bills.
