Known Issues for This Vehicle
Oil consumption
The QR25DE engine is known for higher-than-average oil consumption, which can lead to low oil levels and potential engine damage if not monitored regularly.
Timing chain stretch
Over time, the timing chain can stretch, leading to poor engine performance, rattling noises, and eventually significant engine damage if the chain jumps a tooth.
Intake manifold gasket leaks
This can cause rough idling, increased fuel consumption, and in severe cases, engine stalling.
Catalytic converter failure
The QR25DE engine has been associated with premature catalytic converter failure, which can cause a significant drop in power and increase in emissions.
Crankshaft position sensor issues
Faulty crankshaft position sensors can lead to difficulties in starting the engine, intermittent stalling, and poor performance.
Throttle body problems
Dirty or failing throttle bodies can cause erratic idling, poor throttle response, and stalling.
Exhaust manifold cracks
These can lead to exhaust leaks, reduced engine performance, and increased noise levels.
