After purchasing a Nissan Sentra gxe 2002 -- about 1 month later the service engine light came on and I had to pay almost 300 dollars to replace the radiator thermostat--of course this repair and the next was not covered by the warranty that I purchased--after 5 months both engine belts had to be replaced--another 175 bucks. Now I hear a suspicious creaking from the rear end--I can't wait to find out what that is. Oh--I almost forgot--one day after taking the car home I had to repair a rear tire and the paint is peeling and fading.
Nissan Sentra 2002 the consumer experienced a squeaking noise from the engine. The service department suggested that the noise was coming from the alternator assembly or cylinder next to it. The drive belt was adjusted due to looseness. The vehicle stayed quiet for three days then the noise started again. The weather could cause a glaze on the drive belt which caused noises. The belt was replaced.
I own a 2002 Sentra spec v and this is my second one in 10 months that has failed to perform as it should. The current vehicle has had 1 new engine, 1 exhaust manifold, 2 window regulators, 2 new windows, three new door speakers, two shift knobs, 1 timing belt tensioner, 1 third brake light, and is in the process of getting it's third engine. Car consumes oil at a rapid rate of 2 quarts per 1200 miles. Tried an informal resolution and Nissan rejected. Dealer agrees the car should be bought back. Symptoms that I have, lead to possible engine fire and is being addressed with a recall. I was sent home in a vehicle that was unsafe and they did not want to fix this last time and were denying the car had any problem. I fought a long hard battle just to get it fixed.
While driving at any speed vehicle stalled. Consumer restarted the vehicle, and took it to the dealer for inspection. Mechanic determined that the mass air flow sensor needed to be replaced, and replaced it. The mass air flow sensor has been replaced several times but the stalling recurs. The oil pan, rear main seal and front engine seal were leaking oil. The vehicle drive belts also needed to be replaced.
