Nov 2017, Altima had 18,173 miles, not one year old and the check engine light came on while drive it. Took it to dealer in san diego, diagnosis was a p0101 code (mass air flow sensor/orange pcv valve). Then at 20,598 miles, I saw my life flash before my eyes. I was driving on interstate 5 in southern California doing 72 mph with a truck behind me and all of a sudden the Altima will not accelerate! meanwhile the rpm's are jumping up and down. Again the dealer said it was code p0101, replaced the pcv valve again. Next at 20,833 miles the check engine light came back on. Dealer informed me there was carbon build up in the throttle body and found code p0101 as well. At that point the dealer replaced the throttle body with a new one. At 24,095, the dealer stated both shocks were leaking. Both shocks were removed and replaced. At 25,076 miles the back driver door would not open from the inside. The dealer replaced the acuator. At the same encounter, the back driver window did not roll down more than half way. Found vapor barrier and cable damaged. Also, during this time poor acceleration was noticed and they replaced the brake light switch and deleted stop lamp relay. Finally on this visit new heat shields as well. This car has spent 25 days of its life at a Nissan dealer. This car is scary and defective.
