Less liked than most on YouTube: YouTube owner tone None/100, #111 of 165 engines with a YouTube study (in the bottom third); 3 engine-related recalls on record, 3 known issues listed below.
Known issues on record
- Fuel return hose recall (Recall). On some 2003-2004 Eclipses, Spyders and Galants, a restricted fitting on the fuel pump can build too much fuel pressure and make the return hose leak. Leaking fuel near an ignition source can start a fire. A second 2004 recall covered a badly molded fitting. Fix: Dealer checks fuel pressure and modifies the pump (NHTSA 03V-442), or replaces the pump (NHTSA 04V-312). 3 owner complaints to NHTSA mention it (3G Spyder (D5xA) Eclipse Spyder).
- Crank sensor wiring recall (2001) (Recall). On some 2001 Eclipses, Spyders and Galants, the crankshaft position sensor harness can rub on a heat shield and short out. The engine can then die while driving. Fix: Dealer re-routes the harness for free (NHTSA 00V-299). 9 owner complaints to NHTSA mention it (3G Spyder (D5xA) Eclipse Spyder).
- Transmission cooler hose recall (2001) (Recall). On 2001 Spyders with automatics (and 2000-2001 Eclipses and 1999-2001 Galants), a badly made transmission cooler hose can leak fluid. Fluid on the exhaust can smoke. Fix: Dealer replaces the cooler hose assembly (NHTSA 01V-011).
- No engine failure pattern (Owner-reported (NHTSA)). NHTSA has 79 owner complaints on 2001-2005 Spyders. Most are about the body, wheels, tires and air bags; only a handful mention the engine.
