📖Chrysler Sebring Coupe ST-22: muscular fastback style underpinned by Mitsubishi durability

Chrysler Sebring Coupe (ST-22) (2000-2007)

The Sebring Coupe ST-22 carried forward the successful Mitsubishi partnership into the 2000s. Built in Normal, Illinois, on the third-generation Mitsubishi Eclipse platform, the ST-22 coupé shares virtually nothing under the skin with the Chrysler-engineered Sebring saloon or convertible. Instead, it offers genuine Japanese mechanical durability cloaked in dramatic, muscular coupé coachwork. Consistent Chrysler Sebring maintenance preserves the smooth refinement and punchy performance that make this unusual coupé so satisfying to drive.

Power is supplied by either a 2.4-litre four-cylinder or the robust 3.0-litre Mitsubishi 6G72 V6, paired with a five-speed manual or a four-speed Sportronic automatic transmission with manual sequential override. The 3.0-litre SOHC V6 relies on a rubber cambelt that demands strict renewal to safeguard its interference cylinder heads. On the road, the car combines broad torque delivery with long-legged gearing, making it a capable and relaxed long-distance cruiser.

Owner notes

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

Reassuring points

Reliability
  • Bulletproof 3.0-litre Mitsubishi V6 engine delivers generous low-end torque and long-term mechanical reliability.
  • Practical fastback hatchback tailgate opens to reveal an expansive, highly versatile luggage compartment.
  • Shared mechanical components with the Mitsubishi Eclipse ensure readily available replacement parts and specialist knowledge.

Chronic weak spots

Keep an eye on
  • 3.0 V6 engine (6G72): verify cambelt replacement history, check for oil leaks at valve cover gaskets and inspect rear bank spark plugs.
  • Sportronic automatic transmission: check shifting quality in both manual and auto modes, ensuring correct Diamond SPIII fluid servicing.
  • Front strut towers and chassis rails: inspect closely under the bonnet for structural rust blistering around welded seams.
  • Engine and gearbox mounts: check rubber insulators for tearing or collapse, which causes heavy vibration in drive at idle.
  • Front suspension running gear: inspect lower control arm ball joints, track rod ends and anti-roll bar drop links for play.

Critical deadlines

Do not miss
  • Replace the cambelt, hydraulic tensioner and water pump every 100,000 km or 5 years on both 2.4 and 3.0 engines.
  • Drain and refill the automatic transmission with approved Diamond SPIII / compatible ATF fluid every 50,000 km.
  • Renew spark plugs (including rear bank plugs requiring inlet manifold removal) every 60,000 km.
  • Inspect front suspension ball joints, wheel bearings and anti-roll bar bushes every 20,000 km.
