According to Au7o's research across NHTSA recalls, manufacturer TSBs, and owner forum reports, the 1991 Mitsubishi Eclipse has 10 documented issues. The most frequently reported are: AWD (GSX) Transfer Case Lockup - NHTSA Recall 98V069000, AWD Transfer Case Lockup and Output Shaft Seal Leaks (GSX, NHTSA Recall 98V069001), Balance Shaft Belt Failure Destroying the Timing Belt (Interference 4G63). Of these, 5 are rated critical and should be addressed promptly.
The 1991 Mitsubishi Eclipse has 10 known issues compiled from NHTSA recalls, manufacturer TSBs, and owner forum reports. 5 issues are rated critical: AWD (GSX) Transfer Case Lockup - NHTSA Recall 98V069000 and AWD Transfer Case Lockup and Output Shaft Seal Leaks (GSX, NHTSA Recall 98V069001) and Balance Shaft Belt Failure Destroying the Timing Belt (Interference 4G63) and Front Subframe / Crossmember and Rocker Rust Corrosion (salt-belt cars) and Timing Belt Failure on Interference 4G63 (catastrophic valve damage). Prospective buyers should inspect for these issues and factor potential repair costs into their purchase decision. Regular maintenance following the manufacturer's schedule helps prevent many common problems.
Repair costs for known Mitsubishi Eclipse issues range from $50 to $4,000, depending on the specific problem and whether you choose DIY or professional repair. Au7o provides step-by-step DIY maintenance guides that can help reduce repair costs.
NHTSA recall 98V069001 establishes that certain AWD Eclipse vehicles can experience transfer-case lockup from insufficient lubrication, creating a loss-of-control risk. The manufacturer remedy is inspection of transfer-case oil volume, leakage and operational degradation, followe… Severity: high.
On AWD GSX (and Talon TSi AWD platform) cars, the transfer case output shaft seal leaks gear oil until the case runs dry, and per NHTSA recall 98V069001 'lockup of the transfer case can occur due to insufficient lubrication.' Owners have reported the wheels locking at 50-68 mph,… Repairs typically run $300-$2,000. Severity: high.
The turbo 4G63 is an interference engine, and its narrow balance shaft belt runs directly alongside the main timing belt. When the aging balance shaft belt frays or snaps — common on neglected 1G six-bolt and 2G seven-bolt cars — the debris gets caught in the timing belt, causing… Repairs typically run $1,500-$4,000. Severity: high.
Like most DSM-era cars, 1990s Eclipses in road-salt regions suffer structural corrosion of the front crossmember/subframe (which locates the lower control arms) as well as the rocker panels, strut towers, and rear subframe/trailing-arm mounts. Because the lower control arms bolt… Repairs typically run $500-$2,500. Severity: high.
The DOHC 4G63 (both the naturally aspirated 4G63 and turbo 4G63T across 1990-1999) is an interference engine: if the timing belt snaps or jumps, the pistons strike the open valves, bending valves and often damaging the head and pistons. These belts were specified for replacement… Repairs typically run $600-$3,500. Severity: high.
Both 1G and 2G Eclipse/Talon bodies rot in predictable places: the rear wheel arches and the lower quarter panel just ahead of the rear tires, the rocker/support area under the doors, and — most structurally serious — the front strut towers. The arch and rocker seams trap road sa… Repairs typically run $500-$3,000. Severity: medium.
The electrolytic capacitors in 1990-1994 ECUs have defective seals and leak electrolyte onto the circuit board, corroding traces and surface-mount components — 1990-1993 units are worst, and the front capacitor in 1990 ECUs is known to short and burn through the board under it, t… Repairs typically run $50-$300. Severity: medium.
The 4G63 uses a cam angle sensor (an optical sensor mounted in the distributor housing on the exhaust cam) to provide the crank/cam timing signal to the ECU. With age the CAS optical disc, LEDs/phototransistors, and internal bearing wear out and produce erratic or lost signals. O… Repairs typically run $200-$550. Severity: medium.
The 4G63's hydraulic lash adjusters (lifters) are notorious for clogging with oil varnish or bleeding down, producing the infamous DSM 'lifter tick' from the valve cover. The early-design lifters used in 1G cars were revised twice by Mitsubishi specifically to address the noise. Repairs typically run $150-$900. Severity: low.
As the 4G63/4G63T ages, the valve stem seals harden and shrink, letting oil seep down the valve guides into the combustion chamber. The signature symptom is a puff of blue smoke on startup or on a quick rev after the engine has idled for a while, plus gradual oil consumption. Tur… Repairs typically run $400-$1,200. Severity: low.
