The dealership called me to say that it was done four days later and that the starter was not working. They admitted that it had been working perfectly and had just stopped working while they were moving it around and running it through the wash. I explained that everything had been working perfectly when I brought it in and they agreed to replace the starter with a rebuilt for no charge. …”

Recalls and investigations

On certain sport utility vehicles, the accelerator cable can stick so that the engine speed will not immediately decrease upon release of the accelerator pedal.
- 94V132000Jul 19, 1994Engine and engine cooling › EngineCovers: Isuzu Trooper 1992–1994, Rodeo 1993–1994, Honda Passport 1994
Constant expansion and contraction of the cylinder head causes the camshaft seal end plug can become dislodged from the cylinder head. This allows oil to leak from the camshaft.
