I was pulling through a shopping center, when my Sentra started stalling. I parked the vehicle and it would no longer start. I bought a code reader and it stated a few codes such as ecm, cam shaft position sensor, and accelerator position sensor. I had it towed to hudson Nissan and they stated that the ecu/ecm has shorted and shorted the throttle body sensor. Which could have been extremely dangerous if I were traveling at a higher speed, or in traffic.
We bought this low mileage car from a family member but after buying this car it started getting plagued with the car suddenly and mysteriously shutting off in the middle of driving. Engine died unnanounced car cuts off and the power steering and power brakes stop working. It would happen up to 5 to 7 times a week intermittently. We had taken it Nissan two different times in April to complain about the situation they were unable to diagnose or solve the problem for us or reproduce the problem during test drives. In August took this car back in after it wouldn't run at all and they finally told me it was a camshaft positioning sensor. After replacing this part it runs fine now. After looking online on the NHTSA website it seems this part is part of a recall for this make and model year however I was told it didn't apply to my VIN. I spoke to Nissan headquarters and they again told me they wouldn't cover this as it is not part of a recall. This part looks like it is problematic in this model year and make and also for other cars across the Nissan lineup. I explained that this was a serious problem and it resulted in some significant safety issues. Each time I was able to safely pull off the the side of the road but if it stalled and I wasn't able to get off the highway, or it stalled at an intersection or pulling into traffic say the consequences could have been deadly. I was also lucky that the steering wheel didn't lock up turning the wheel with the car off. Our symptoms with this car were classic. I was very surprised that they could not diagnose this problem in April as the symptoms match they have for known recalls on this and other cars. I would like it covered but more importantly I think the recall should be extended to other vehicles and vins to save lives.
Check engine light came on after starting car after oil change at local shop. Mechanic checked code, problem with camshaft position sensor. Part replaced. Problem solved, check engine light stay off. After 1 week, check engine light came on and again, camshaft position sensor needs replaced. Car timing clearly off - when attempting to accelerate car jolts and shudders hard enough to slam driver into seatbelt. When vehicle warmed all the way up problem nonexistent. Camshaft position sensor changed again, problem reoocurs within a week or two. During fall/winter when cold weather occurs engine must be completely warm to avoid being shaken and jolted around while accelerating. Check engine light remains on. Dealer states "timing chain is out of time" and must be replaced. Nissan north America states car not on recall list, although recalls listed here seem to apply to my vehicle.
