Bought vehicle new 14 months ago and the battery already had to be replaced. At my expense. Dealer service informed me may have trouble if not replaced. I wrote Nissan and they told me the following: "Nissan is not in the position to provide vehicle service contract coverage or warranty coverage. Nissan depends on its Nissan dealers to provide any and all warranty coverage concerns as they are in the best position to assess the vehicle and determine whether a part is warranty or not. We recommend you continue to coordinate with your local Nissan dealer??S service department with any warranty inquiries. " since Nissan itself will not properly look into the situation I will no longer purchase a Nissan and they have lost a loyal customer since 1972.

The contact owns a 2010 Nissan Altima. The contact noticed that the owner's manual stated that the ignition switch on position could not be switched to the off position until the shift selector was moved to the park position; however, he was able to shut the vehicle off while the vehicle was in another gear other than the park position. The dealer was unaware of the failure since they did not reply to any attempts to contact them. The manufacturer was notified and advised the contact to notify NHTSA. No repairs were performed. The current and failure mileages were 15,000.

2010 Nissan Altima S (purchased new 12/7/09) and as part of the incentive to buy the vehicle, the dealership had after market leather installed and from there the problems have been non-stop. At this point, I believe the problem is electrical. I have taken my car nearly 10 times (one being today) in the past 15 months for service and was placed in loaner cars at least 4 times due to the problems. The passenger seat air bag not working and tire pressure light sporadically comes on both blinking and/or a constant. My entire seat was replaced and still the air bag light takes up to 5 minutes sometimes (it varies) to turn off indicating someone is in the seat. I have driven up to 4 miles with my passenger being unprotected. The dealership, today says this is normal. The tire pressure light has came off and on since the car was purchased with nothing found to be wrong each time, except once, they said I had a nail in my tire and they plugged it. I have never seen the repair work and looked very well... this past weekend, I vacuumed my entire car (meaning each door had been opened and shut) taking approx 15 minutes. When I got in the vehicle and tried to start it the shift was locked and the car would not start. All lights started blinking and then completely shut down. It would show "on" on the start button while not running. I was jump started and then instantly the tire pressure light blinked for one minute then stayed constant. The air bag sensor took even longer to work. Of course, when I took it to the dealership today, nothing was wrong--battery was good--air bags are good; however, they did confirm low tire pressure in one tire... I truly believe it is an electrical problem and the company is not standing behind their product. I am beyond frustrated and truly dishearten by Nissan and their lack of concern for their customers' safety and well being.

2010 Nissan Altima. The automatic push button ignition would not start the engine. It cranked several times then did nothing when pushed. Waited 15-20 minutes and then it started right up. Upon starting the car was taken to the dealership. The mechanic was unable to determine the failure because no error codes registered. They checked further but couldn't find the cause and told me it would have to totally break before they could find it. This is an electrical system ignition flaw and we're extremely concerned about the safety of this vehicle and of being stranded.

'09 Altima would not start. Second occurrence in one week. Jumped car and took it to gettel sarasota, fl Nissan dealership. Diagnosis - faulty "brake switch", needed to start keyless ignition they told me it was a "common" problem with these cars. Replaced part and no problems since. Keeping my fingers crossed. My so has a '07 Altima, and experienced the exact same problem the same week in naples, fl. Mine was covered by warranty, but he had to pay for a new part. Go figure! I believe this to be a serious problem and should cause a recall. ( no old parts available, to my knowledge.)
