Strong exhaust odor inside car. Cracked exhaust manifold was found,second one I will have to put on car,first was discovered at approximately 85/88000 miles. Read forums and discovered earlier versions were recalled for same problem and seems to be a common problem among later models. Got a headache from strong smell. Very noticeable when car is stationary/idling.
When I was driving my Nissan Altima 2012 car on I-635 in dallas at 2 pm cst at around 65 mph speed, I heard huge explosion sound on top of my head. I turned on the hazard light and slowed down the car and pulled over to a shoulder and checked the car. Sunroof glass was exploded and I have seen a 4 inch diameter hole and scatter glass pieces; rest of the glass was also broken/cracked. There was no vehicle at the time the incident occured and it was not due to the external forces, it was due to internal pressure between the glass and visor. I was so scared when the glass exploded but luckily escaped from the bodily injuries. The sunroof glass on the Nissan Altima 2012 is for sure defective product. Please investigate and save the lives of the drivers. I'm not expecting any financial compensation from Nissan or anybody. I don't want this to happen to anybody please investigate and save drivers.
On July 18, 2016, while parked at work on the side of a road, the right front passenger window shattered. The police determined it was not caused by anything hitting it. The window that shattered was facing a yard, not the street, so no projectile object hit it. The police thought it might be the heat (in the 80's, but in NY, and we had it for 18 months in nc where it's a lot hotter, with no incident). Then on August 20, 2016 the car was parked at a grocery store parking lot. When my son came out of the grocery store, there was a 14 inch crack in the windshield that was not there when he went into the store. No evidence of any projectile hitting the glass. The car is 3 years old and 35,000 miles. Temp outside: 85degrees. No reason why these windows (2 in 1 month) should be shattering spontaneously by themselves. No rocks or other projectiles involved. Both times the car was parked next to other cars, and nothing happened to the other cars.
