Electrical system
35 reports1 related recall
“The car quits as I’m driving it , The headlights and the dome lights go dim and radio light flickers then it goes completely out and when I’m driving the car it has a rough idle and in order to keep the car running when I get to a stop light or stop sign is to put the car in park .”
Engine
24 reports
“PCM ECM ECU ENGINEERING FLAW. ENGINE KICKS INTO SAFE MODE WHILE IN OPERATION OR COMPLETELY STALLS, CHECK ENGINE LIGHT ON, WHEN RESTARTS WILL MISFIRE. DIAGNOSED WITH FAULTY CONTROL MODULE (THE SECOND ONE IN THIS VEHICLE SINCE I HAVE OWNED IT)”
Air bags

“2003 NIssan Sentra. Consumer writes in regards to Airbag Safety Recall. THE CONSUMER STATED THE PARTS NECESSARY TO COMPLETE THE RECALL REPAIR WERE UNAVAILABLE. THE CONSUMER STATED THE DEALER WOULD NOT PROVIDE A LOANER VEHICLE FOR THE LENGTHY REPAIR.”
Power train
9 reports
“I WAS DRIVING AND THE CAR SHIFTED ITSELF FROM A LOW GEAR TO A VERY HIGH GEAR, LEAVING ME WITH NO TORQUE. THE NEXT GEAR WOULDNT LOCK-IN UNTIL RPMS HIT REDLINE, AND EVEN THEN IT WOULD FEEL LIKE ITS SLIPPING, OR MAYBE ITS IN OVERDRIVE GEAR(4TH) WHEN IT SHOULD BE IN 3RD.. AND ALSO THE TRANSMISSION WOULD NOT SHIFT DOWN UNTIL I CAME TO A COMPLETE STOP... THIS IS VERY DANGEROUS WHEN YOURE ON THE FREEWAY, BECAUSE THE CAR WILL ONLY MOVE 40 MPH. AND ALSO DANGEROUS WHEN CLIMBING HILLS/FREEWAY OVERPASS, BECAUSE THERES NO TORQUE TO GET UP THE HILL, AND THE TRANSMISSION WONT PUT ITSELF IN LOW GEAR UNTIL YOU COME TO A COMPLETE STOP... I THINK ITS AN ELECTRICAL ISSUE BECAUSE IT HAPPENED SUDDENLY... IF IT WAS MECHANICAL, I WOULDVE FELT IT SLIPPING GRADUALLY, AND IT NEVER SLIPS. I JUST DROVE IT A COUPLE DAYS BEFORE TO THE BAY AREA AND IT CLIMBED THE HILLS SMOOTHLY, NO PROBLEM.. I HAVE NO CHECK ENGINE LIGHT, SO IDK WHAT THE PROBLEM COULD BE...”
