Engine Belts And Pulleys problems of the 2013 Nissan Altima

When pushing the gas on the highway or the streets it feels like the power of the car is holding back. Feels like the gears are messing up. And there's problem with catalyst converter. It's always showing check engine light even after I have tried other solutions on fixing that and the gas odometer is not reading the gas levels right either. Plus the passenger seat buckle is stuck and doesn't latch to the seat belt for a hold from a car accident. Like you have to really push hard for the seat belt to hold on.

Passenger light airbag is never detected. (been on going for a couple of years) engine light stays on (for about 3 months) seatbelt airbag (3 months) will not go out. There is never a recall and a problem is never found by mechanic. Can get the engine light off for a little while, but comes back on usually within a week.

Wife was driving west bound on ohio st rt 125 doing 40 mph when a car going east bound on ohio st rt 125 attempted to make a left hand turn in front of her and hit her head on bringing the car to a complete stop in just a couple feet. None of the airbags went off . The seatbelt did not lock up. None of the safety equipment on this car worked during this head on collision.

When sitting the front passsenger seat passenger air bag off sign comes out and randomly disappear,appear repeatedly. Sit the very properly by owner' manual it comes out. It means passenger ait bag is off sign on it will not inflate in a crash. I'm very scary drive this car with someone who sit the passenger seat. Although sitting on the seat properly and useing the seat belt properly it doesn't matters because th epassenger air bag off light always illuminate. It is very dangerous in a crash. I really want to know need air bag for what??? Nissan already recalls some car same issues. I bring my car Nissan dealer,they do nothing and say"this is normal" and have same problems my car's VIN# not include the recalls so they don't fix or replace anything. It is ridiculous. Also Altima has wierd winning high pitch noise all the time and drive low rpm to chang to high rpm makes very loud rumbling knocking noise. It seems like a drive belt and tentioner problems. Dealer say that it is normal. Dealer always say "it is normal". If my warranty is finish they say that it is problems. I really want to solutions.

When starting the car the starter would keep cranking after the release of the start button, the passenger air bag light stays on sometimes even when a passenger is in the seat also the rear seat belts are very hard to lock in do to the receiver end pushes down into the seat when driving there is a few problems the low end rattles and shakes and 45 and above there is a wining noise from the engine compartment that sounds like a bad alt bearing or trans problem it gets louder the faster you go very annoying with today technology these problems and this is just a few is a big step back for Nissan not a happy customer just broke 6000 miles.
