general problems of the 2001 Nissan Altima

I was driving from work when I heard a cranking/squealing sound coming from the rear passenger side, I stopped and checked could not find anything, but noticed that anytime I stepped on the brakes/make a turn the sound will come on, took it to a mechanic who told me it was the motor mount and also that the brakes were been affected and I could not drive more than a certain mile on the highway. Also the engine light keeps coming on my dashboard, after several repairs to whatever the problem was, it;s still on, now no one can tell if it is related to the issue car had or not, the headlights on the car hardly come on properly, even if I put them on full light, it's still looks dim and I can see with them at night when am driving, the heat suddenly comes on even without turning it on, am really scared now cause I don't want to get in an accident. Nissan needs to do something anout all this complaints especially with such high recalls .

While stopped at a traffic signal the engines rpm would fall below 500 and at times would stall the engine making me vulnerable to a collision. It got so bad my daughter would not drive the vehicle. I took the car to several mechanics over the course of a year and no one could fix the problem tune ups and such did not fix the problem, I spent hundreds of dollars trying to eliminate the problem to no avail. I finally took it to a mechanic with a smoke machine and he found the intake manifold had a leak and that was the problem cost $850. 00 plus tax. I researched intake manifold vacuum leak on the 2001 Nissan Altima and found that there were hundreds of Nissan owners with the same vacuum leak! several of the Nissan owners had to make the repair more than once, some people spent hundreds of dollars on various fixes that did not work, I was told by one mechanic that it was the catalytic converter luckily I did not go for it. I believe it is a safety defect because when the car stalls in the middle of the road unexpectedly it leaves you wide open for a crash or worse!! I think Nissan, north America should be responsible for the repair, it seems to be a defective intake manifold gasket or poor engine design which cause's the gasket to fail- it may also be too close to a heat source (the exhaust manifold) causing the gasket to fail. I think it is unfair to the consumer to pay for this repair because it happens to so many Nissan's.

When I bought the car there was a piece of tape over the airbag light and auto zone helped me take it off. The Nissan died getting off the interstate and I lost all control of the steering and brakes. Later to find that I needed a oxygen sensor and now electrial problems with the airbag light being on. I took the car to the dealership and they said I needed evac hoses but all the dealer did was unhook one so they could charge me for codes because they could not find my problem with no engine light present. So my machanic found the unhooked hose and put it back on and it was previously not unhoooked. The car dies randomly in traffic and is very hazardous to be rear ended or even to hit some one else with the dealer not even knowing how to properly resolve this issue???? my machanic will be helping me to make this car safer for me to drive.
