Ny exhaust manifold is having trouble I've been told that there's been a recall but cannot find anything recent. My tire pressure monitoring system isn't reading correctly either and I'm scared I'm going to get into an accident. My exhaust manifold there's a loud noise coming from it according to the shop that checked my car. I've kept up with all maintaince I am unsure what is happening.
Takata recall the exhaust manifold has a large crack in it, leaking fumes into the cabin of the vehicle. I replaced the part 6 months ago. I'm already having problems with the new part. I've seen numerous Nissan Altima's on the road with the same problem (very loud exhaust). There must be a design flaw that causes the metal to weaken and break.
The exhaust manifold cracked allowing carbon monoxide to enter the passenger compartment. This is a severe safety hazard that Nissan is aware of. Nissan refused to repair this under warranty as the vehicle had 100k miles on it. This is a common problem on 4 cylinder Altima's this is caused by a defective part which should be repaired under warranty due to it's inherent safety concerns. This can cause occupants to pass out while driving with the possibility of causing damage and injury to third party individuals. Nissan should be required to repair all issues surrounding a cracked exhaust manifold under warranty. This should not have a mileage limitation imposed. Simply stated an exhaust manifold should not exhibit cracking under normal driving conditions for the lifetime of a vehicle. This is a southern car with no evidence of rust on the effected part. Part is available for inspection.
5 yrs ago the sound of my engine changed and upon inspection the welding on the exhaust manifold was cracked. I was informed by pembroke pines Nissan that since car is at 38,500 miles and out of warranty despite it being a manufacture failure it would set me back $975. I didn't have the repair done. For the past 3 yrs, my passenger airbag light will turn off and on even irregardless if someone is in the seat or not. Furthermore, the radio will go blank or have illegible characters on it. I too have the melting dash issue as well as a couple of times I slipped and my finger nail has gouged out pieces of dash board. It's amazing that Lexus has issued a recall on their melting dash board on the is250 & is350 issues but Nissan could care less about its brand or reputation; I guess that's what happens when the company isn't whole japanese owned.
Manifold, I have taken it to the shop, they told me that it could be the manifold or gasket, is there a recall on that part, very unsafe car fills up with the smell of gasoline it also rusting on the back by the wheel it seems to me that its to early to be rusting poor paint.
Upon driving the vehicle there was a strong smell of gasoline inside the cabin of the vehicle. The vehicle started smoking while driving immediately the car ran hot. Had the car towed to nearest dealer that then informed that the exhaust manifold/catalyst converter had failed and was leaking. Which they informed me was very dangerous but they where not responsible for repairs which led to cracked heads on the motor and eventually total engine failure. What a safe vehicle for a single mother of two children? not so much,.
Tl- the contact owns a 2008 Nissan Altima. The contact stated that carbon monoxide was leaking into the passenger's side vents from the exhaust manifold. The contact took the vehicle to a mechanic, who stated that the manifold would need to be replaced. The vehicle was not repaired. The failure and the current mileages were 87,000. Kmj.
