2003 Infiniti I35 Electrical system Problems

“I bought a 2003 infinit I35 a year ago as my first car. I have been having problems with my vehicle dying for what seems to be no reason. No warning lights would come on not even a check engine light. I was driving on the highway when it happened a week ago. While I was driving it died a total of four times. When I tried to start it back up it wouldn't turn over. It would not take a jump. No fluids were low. No cables or terminals were loose. I ended up having to get the vehicle towed. At the time it had 216,000 miles roughly. …”

“While driving down the street, the vehicle shut completely off. I could not steer or anything. It was not the battery, alternator. It just stop right in the middle of the street; which is very dangerous. I called the used car dealer whom had just sold me the vehicle less than 6 month whom had the vehicle towed. They indicated they fixed one of the sensor & there was electrical issues. It drove for about a year, now it is continuously doing the same thing, shutting down while driving. The check engine light will come on & slip/ tcs. …”

“I understand that per campaign NHTSA # 03v455000 - crank/cam positon sensor weld, my veh was part of this recall.. Infiniti I35 2002-2003 and I was not notified.

This continously happent to my vehicle where my check engine warning light comes on , I have no power & the vehicle stops running with no warning during operation which is very dangerous. …”

“I've had the same problems that other Infiniti I-35s have experienced in regards to losing power, engine cutting off and lack of braking. My car initially stalled while I was parked at a red light. After a few attempts to restart, it finally did. I made an appointment to see the dealer about this problem four days later. While driving to the dealer, my car engine lights all lit up and the car stalled and I had no braking ability. Fortunately, I was going only about 10 MPH when this happened and was able to pull over to a lane without cars and applied my parking break to stop the car. …”

“The car suddenly loses throttle control under normal driving conditions; the engine return to idle speed . I was driving on the expressway and all of a sudden the check engine light came on and the car started slowing down. I pressed on the gas pedal all the way down but the car refused to accelerate. I managed to pull over and stop the engine. And then restarted the car and it seemed to work ok for a while and then did it again. I managed to get it to the dealer and it has been there since while they try to figure out why this is happening. This problem started happening about a year ago. …”
