RepairPal has identified the most common problems with the 2001 Nissan Altima based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The engine may stall at times due to a failed crankshaft position sensor and/or camshaft position sensor, These sensors can fail intermittently as they warm with the engine. Sensors on certain models have been recalled by Nissan and will be replaced as necessary. Please visit our recall section for this model to see if your vehicle is covered by this recall.
The catalytic converter closest to the cylinder head can fail causing illumination of the Check Engine Light. Prompt repair of this problem is recommended because the catalyst material can be sucked into the engine and cause internal damage.
Failure of the ignition power transistor can cause a "crank-no start" condition.
The engine mount on the right side can wear prematurely and cause excessive engine movement.
The AC system may blow warm air due to refrigerant loss caused by a leaking low pressure AC hose. These hoses commonly develop a leak at the hose crimp connection.
The front struts can wear prematurely and create a knocking noise when driving over bumps.
The Check Engine Light may illuminate due to a defective canister vent control valve in the emissions control system.
