2006 Nissan Altima Problems
RepairPal has identified the most common problems with the 2006 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.
Failure of the ignition power transistor can cause a "crank-no start" condition.
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.
Nissan issued a recall on the fuel pump for premature failure. There was an owner notification program and labels were placed on the fuel pump access panel and next to the AC charge label in the engine compartment.
Crankshaft and camshaft position sensors can leak oil into the connector causing Check Engine Light illumination. The engine may also stall as a result. Leaking sensors should be replaced. Certain 2002 models were recalled for a separate camshaft and crankshaft sensor issue. For more information on the recall please click here»
The engine mount on the right side can wear prematurely and cause excessive engine movement.
The throttle body for the Nissan Altima is known for carbon buildup, and requires regular, light cleaning to maintain peak performance. After cleaning the throttle body, many owners notice a very high idle, erratic (bouncing) idle, and unpredictable power surging.
The cause is normal ECU adaptation: When the throttle body builds up carbon, the rate of airflow is slightly decreased. The vehicles computer reads this decrease in air volume, and adjusts the throttle body settings to maintain the proper engine idle speed. When the carbon is cleaned out, the ECU now registers too much air, and cannot adjust back to the original settings. While it is trying to change settings, the idle will bounce from low to high, and the car will surge forward at times.
It has been recommended to simply wipe inside the throttle body every 12,000 miles, and never to touch the flap inside. Also, the cleaning procedure may be best left to a qualified technician.
The solution can be as simple as disconnecting the battery for at least an hour, having the dealer reset the computer, or, in extreme cases, replace the throttle bodies.
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.
The thermostat may become stuck closed, causing an overheating condition. Replacement of the thermostat will be required to correct this concern.
The external seal on the engine oil cooler can fail and create an oil leak.
Several owners have reported instances of vehicle stalling at random. Professional diagnosis by a qualified shop is recommended. Issues could begin with various engine control sensors to fuel system modules and other major components. Diagnosis of the issue will prevent unnecessary part replacement and expenditure.
