On two occasions while making right turns, the engine failed to operate. The first occurrence, the engine restarted and appeared to operate normally. The second occurrence, the engine failed to restart and the vehicle was towed to Nissan maintenance where it was determined that the battery was leaking acid, which was ingested in to the air intake, destroying the air filter and causing severe contamination of the spark plugs and fuel injector system, as well as corrosive damage to the framing. Had this engine failed on the freeway, it would have jeopardized the lives of the occupants. Action is being addressed with the battery manufacturer, but this report is implemented to address the poor design of the vehicle which placed the battery above the air intake, without provisions for containment in the event of such an acid leak.

Vehicle began making a ticking noise from front passenger engine area at a stop light, as I began through intersection once it turned green the car completely stalled on me as traffic began moving again in the opposite direction almost causing a collision in the middle of the intersection. There were no pre warnings, dash warning lights that came on prior to this incident. I took the vehicle to the Nissan dealer the next day (4 year old car w/ 75K miles) and was told the noise is coming from the engine I need a new motor but would not elaborate as to what exactly it was but advised me I was out of warranty and I could buy a new motor from them for 6500$. being completely stuck in the middle of the intersection has scared me enough not to even want to get back in the vehicle so as of right now it sits in my driveway a 4 year old car with 75K miles on it that almost caused me to be tboned in an intersection and no one has any answers for me, only want money to give a new motor. Nissan Corp has been contacted with out any assistance provided. I was told by Nissan not to drive the car, which I obviously wont, I have done my research and there are hundreds of complaints out there for the same exact "unknown" problem that many people have had.

I have a 2007 Nissan Sentra with 53,000 miles. Started making loud rattling noises when turning to right and when cold to start. Started to get very scary and took into mechanic, since Nissan charges $120 just to diagnose, even if under warranty. Mechanic said it was the right motor mount and was extremely unusual to see with such low mileage. I spoke with a friend that worked at Nissan dealership and he said it always happens, and should be a recall. I spoke to corporate, and they refuse to help at all. This should never happen when you take good care of your car and have low mileage. I will never buy Nissan again.

The check engine light came on. The dealer told me it was from defective gasoline. When the light immediately came back on, the dealer told me I needed a new engine and denied warranty repairs because I had changed my own oil and could not show receipts from a commercial oil change.

2007 Nissan Sentra caught fire while on the highway. Consumer stated that she just recently received a recall for a brake fluid leak. She would like to know if there is anything that could be done and if this is what caused it to catch fire.

There was a noise coming from the engine side of the vehicle, but it was a separate noise from that of the engine. It was like a rattling/loud sound. Every time I would turn to the right and also reverse, the sound was louder. I took it to the Nissan technician and they found the motor mount was broken. After replacing the motor mount the vehicle sound just like new (just how is was supposed to sound).
