Known Issues
|
|
Turbocharger Reliability:

Early turbo models can suffer from turbo seal wear, cracked exhaust manifolds, and oil starvation if maintenance is neglected. Intercooler piping leaks are also common.
|
|
Engine Mechanical Issues:
|
Cracked cylinder heads (especially on early 4G63T), worn piston rings, timing belt tensioner failure (if not replaced at intervals), and distributor issues are possible.
|
|
Suspension And Chassis:
|
Worn control arm bushings, ball joints, tie rod ends, and leaking struts/shocks are common due to age and use. Rust can be an issue in certain climates, particularly on subframes and rocker panels.
|
|
Electrical Gremlins:
|
Corroded grounds, failing window regulators, dim instrument cluster lights, and intermittent ECU issues can occur.
