📖Chrysler 300C Saloon: imposing American presence built on proven Mercedes engineering

The modern Chrysler 300 made an unforgettable entrance with its chop-top roofline, commanding road presence and muscular proportions. Unlike the subtle discretion of a Mercedes-Benz E-Class, the big Chrysler unashamedly celebrated bold American styling. Beneath its chiselled bodywork, it borrowed key suspension and driveline components from the DaimlerChrysler partnership. Adhering to structured Chrysler 300 maintenance keeps this heavyweight cruiser running at its majestic best.

European buyers favoured the torquey 3.0 CRD V6 diesel (Mercedes OM642), while petrol enthusiasts embraced the sonorous 5.7 and 6.1-litre HEMI V8 powerplants. Power reached the rear wheels through the durable Mercedes-derived NAG1 transmission. However, the car's substantial two-tonne mass places immense stress on front suspension ball joints, track control arms and brake discs, requiring regular underbody inspections.

Owner notes

The reassuring points, known weak spots and deadlines you should not let slip.

Reassuring points

Reliability

Iconic design and imposing road presence deliver unmatched styling character in the executive class.
Robust 3.0 CRD diesel and legendary HEMI V8 engines offer outstanding durability when properly serviced.
Spacious, armchair-like seating and long wheelbase provide first-class cruising comfort on motorways.

Chronic weak spots

Keep an eye on

NAG1 (5G-Tronic) automatic gearbox: inspect the electrical pilot bushing plug for ATF fluid weeping into the wiring harness.
Front suspension running gear: check upper and lower wishbone bushes, ball joints and anti-roll bar links for play.
3.0 CRD OM642: inspect the turbocharger inlet seal for oil drips directly onto the swirl flap actuator motor.
5.7 HEMI V8: monitor hydraulic lifter tick on cold starts, especially on engines with Multi-Displacement System (MDS).
Braking system: check front discs for warping and inspect rear parking brake shoe linkages for seizure.

Critical deadlines

Do not miss

Engine oil and filter renewal every 10,000 km or 12 months, using specified low-SAPS oil for diesel DPF longevity.
Automatic transmission fluid (ATF+4 or MB 236.14) and filter change every 60,000 km to prevent conductor plate failure.
Front suspension overhaul inspection every 20,000 km to detect play in lower ball joints before tyre wear occurs.
