Driving & all gauges in dashboard turned off. The same day, the car didn't respond normally when gas pedal was pressed. The gas pedal was pressed several times before car took in gas. Parked car, & later that day restarted car. Car again didn't respond well when pressing accelerator. Gauges still non operational. Car died & battery tested by aaa. Battery found to be ok, but charging system was issue. Towed to tow yard & told alternator needed to be replaced. New, not rebuilt, alternator replaced by cousin & fuse (not sure which one) was found to be blown & replaced. Gauges worked after fuse & alternator replaced. Check engine light came on several days later. Cked car on auto zones free diagnostic tool & diagnostic trouble code U1001 can communication line & P0462 secondary code given. Car died again bout week later & towed to pep boys. Pep boys said battery needed replacement, so I had aaa test it & aaa said its the charging system. Aaa replaced the battery after much ado. Car taken back to pep boys for 'electronic diagnosis' & they said alternator! alternator tested at separate battery shop & tested fine. Later found meter fuse blown. Took to mechanic specializing in electrical & he scanned PCM & found no communication on data lines. Had blown meter fuse causing false code. Mechanic cleared out codes & test drove. He ckd charge 14.2 volts. Mechanic told me to bring it in if happens again. Well, happened again & replaced meter fuse & ck engine light on again. Electrical mechanic said it's a short somewhere & I'd have to leave car for maybe several days. Had a friend inspect under dashboard & cked under the gear shifter & ckd speedometer wires & didn't find any shorts. Googled "meter fuse Nissan Sentra" & meter fuse has created a lot of problems. Problems listed on forums. I've already spent $550, can't afford to pay Nissan $150 diagnostic fee yet.

I was driving down the interstate, at 60 mph and the engine dropped to 700 RPM and refused to accelerate. I had to pull over, shut off car and repeatedly attempt to start car. This has happened 8 other times in the past month.

Sentra 4-cyl

  • 39,720 miles
Nissan Sentra 2004 model - manufacturer defect - recall required. Dear, this is regarding my Sentra car - doing service only with Nissan dealer. Took the car 3 times to dealer for the same problem - only on the 3rd time they could find the problem. Seems they never came across this type of problem before. Brake booster does not send fluid to brake -stalls the car middle of the freeway/highway from 65/55miles to 5 miles - suddenly comes sudden halt in highway. Gave full acceleration, it doesn't move more than 5 miles/hr. Returned to car dealer again. Avoided several accidents. My services charges were $1,200 - which includes fuel system replacement, brake pads, rotors - at early stage - @39700 miles. Very bad experience with Nissan for the first time - I had Altima before. It is a total manufacturer defect. I am worried as my teen age daughter and wife are driving this car. Informed Nissan, they said it is normal/common defect.

The contact owns a 2004 Nissan Sentra. While driving 65 mph with the vehicle speed control on the throttle slowed down and the vehicle was unresponsive. The vehicle was driven onto the side of the road, the engine was turned off for an hour, the vehicle was restarted and began to drive normally. The check engine light illuminated continuously. The ECM and the electronic throttle body control was replaced by the dealer at cost to her approximately two years ago. She does not know if this cause the vehicle speed control failure to recur. The vehicle will not be taken to the dealer. The manufacturer was not contacted. The failure mileage was 141,000.

The car is accelerating when brakes are applied to stop. It did it once last year and 3 times this year with it becoming more frequent. It has occurred twice in the last 2 months with 8/20/2010 being the last time it occurred.

Car has no acceleration. Will not rev over 900 RPM. While driving lost power but engine kept running fine. It acted like cable broke on the peddle. But to find out it is all electronic. Was able to get off road but was only able to go 10 mph in traffic.

I just want to add a report of (so-called) sudden acceleration syndrome that occurred to me on thanksgiving day of November 2007 then again within a month or two after the Nissan dealer said it was due to a badly positioned floor mat. The second time it happened, the dealer said it was a "dirty throttle" that required $75 "throttle service, " -- a cleaning -- to which I readily consented. The acceleration problem hasn't reoccurred (knock on wood). In both instances, the car sped forward when my foot was off the brake so quickly I barely had time to react. Fortunately, I did not have an accident or cause one. I drive a 2004 Nissan Sentra, which I maintain regularly. The Nissan manual states that throttle service should be regularly performed (something I had never heard of before) but not that neglecting to do so could cause the car to accelerate suddenly. This was not mild acceleration -- the speed increased alarmingly until I put the car in neutral then hit brakes (I instinctively tried braking first, which caused the engine to race) and pulled over to collect myself. This isn't easy with power steering.
