The VQ35DE can suffer from coolant leaks, often from the water pump, radiator, or hoses, leading to overheating if not promptly repaired.
Ignition coil failure
The ignition coils on this engine can fail, causing misfires, rough idle, and reduced performance.
Throttle body issues
The electronic throttle body may develop problems, leading to erratic idle, hesitation, and poor throttle response.
Variable valve timing (vvt) problems
Issues with the VVT solenoids or camshaft position sensors can lead to poor engine performance and check engine light warnings.
Crankshaft and camshaft sensor failure
Faulty sensors can cause the engine to stall or not start, often accompanied by error codes.
Intake manifold gasket leaks
Leaks in the intake manifold gasket can lead to rough running conditions and vacuum leaks.
Mass air flow sensor problems
A failing MAF sensor can cause incorrect air-fuel mixture readings, leading to poor performance and fuel economy.
Fuel injector issues
Clogged or failing fuel injectors can lead to uneven engine performance and poor fuel economy.
