A loud rattle type noise may be noted from the engine after a cold start. This can be caused by a faulty valve timing control actuator. Replacing the failed actuator will commonly correct this noise issue.
The fuel door may not open correctly at times. This may be caused by a lack of clearance between the fuel door and the release latch. The common repair is to slightly trim the top of the fuel door lock tap.
The Check Engine Light may illuminate with a stored code P2422. Our technicians tell us this can be caused by spider webs in the EVAP system charcoal canister vent hose. Acura has made available a spring to install inside the vet hose to correct this issue.
