Nissan Maxima problems: Common problems include a faulty alternator,
noisy timing chain, oil and coolant leaks and the «service engine soon» (emission control related) issues like bad camshaft position sensor (CMP) or crankshaft position sensor (CKP), dirty air flow sensor, faulty ignition coils, catalytic converter, EVAP system issues.
A
timing chain doesn't need to be replaced unless there is a problem with it, however, a
noisy or stretched
timing chain is not uncommon in this engine at high mileage or due to lack of regular oil changes.
