I purchased a Nissan Maxima sl at the start of November 2004. A harness inside the engine containing a sensor to detect engine knocks was damaged by a rodent. This caused the engine to misfire which caused the transmission to buck, stop shifting, change speed of the car on it's own, lose acceleration, not shift, shift suddenly and put the driver in a situation where if they did not compensate they could be injured or killed. The problem started when I bought the car and worsened over the next three thousand miles of driving. The dealer and manufacturer ignored the problem and said they could not duplicate it until I said I would pay for them to plug the engine into a diagnostic computer. At this point they found a misfire code, the problem was identified my the master mechanic and the dealer replaced the harness at my expense! the manufacture refused to take responsibility for a dangerous defect. This is a defect in their computer logic and/or design. A sensor malfunction should not cause an engine misfire and transmission to fail. Note the date of November 3 2004 indicates that the problem started when I purchased the car and it continued until the harness was replaced. I have contacted the manufacturer many times and they are not returning my calls. The master mechanic said he has seen this problem many times before which tells me that this is perhaps a long standing problem that Nissan chooses to ignore.

The steering wheel moves when the unlock button on the remote control is pressed. This occurs on a random basis when one individual remote control is used and 100% of the time when going between one remote to the other. On a random basis, driver seat does not move back when exiting vehicle and that area of the exit feature is enabled. Please note that this is for the Maxima equipped with the memory seat option when the entry/exit feature is enabled. Exterior mirrors move on their own while the vehicle is in operation. Nissan has made 3 repair attempts for each problem stated above and claims that the vehicle is operating as designed.
