2006 Nissan Sentra Problems
The electronic throttle actuator (throttle body) can fail causing a loss of power and illumination of the Check Engine Light.
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.
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 2000-2003 models were recalled for a separate camshaft and crankshaft sensor issue. For more information on the recall please click here»
Screws inside the intake manifold can become loose causing internal engine damage if they fall out completely. Our technicians report that using a strong thread locker on the power valve butterfly screws can help prevent them from becoming loose.

2006 Nissan Sentra Reviews
bought my 2006 sentra with 40K on it and have run it up to 215K.
I love this car. It has always been reliable and has averaged 38 mpg over its life with me. I do alot of highway driving and it's never let me down. The only repair I've made other than routine oil changes was bearings in two wheels. front left and back left bearings were failing and needed replaced. I attribute that to some of my driving habits. lol
I have a 2006 nissan sentra I gave it too my neice it has 53k on it, I had to put a converter on it also struts other than that its a nice car.
I've had this car for about three years now (bought it used at one year old) and the only mechanical problem I've had is that currently the "service engine soon" light is on, and it looks like it's a minor problem with the evaporative system, or some such. Only other complaint is that some of the plastic fixtures on the interior are not the highest quality (i.e. they stick or in one case break). I'm very happy with the vehicle overall, and I get excellent gas milage.
