Electrical System problem #1

While driving in residential/business area my vehicle completely lost power and turned off. I drifted to the side of the road without power steering. Tried to start vehicle again. Vehicle would start but would immediately die-would not idle. After resting approx 5 minutes I was able to start again and continue home. This has happened 3 times in the past 2 months. I am terrified to drive this vehicle again. I also cannot keep the drivers side headlight working. Bulbs constantly blow out at over 300. 00 dollars each.

Electrical System problem #2

The vehicle will lose power to the brakes while driving intermittently. When problem occurs you will lose power steering and pressure to braking system. Also the driver hid headlamp gets moisture in it whenever it rains. I have had to replace the hid bulb about 6 times in the past year. Also there seems to be an electrical issue with the onboard computer that causes the tachometer to not work or read correctly.

Electrical System problem #3

My airbag light stays on constantly. There is a knocking sound that occurs as well when I'm driving. I'm concerned if I'm involved in a collision my airbags will not deploy. I contacted Infiniti and was told they need to reset it and will cost $800. 00 and my extended warranty did not cover it and was not part of the recall list. The ipdm ecm relay switch causes my instrument cluster gauge to go in and out, the check engine light comes on, my truck jerks trying to switch gears, it will sometimes start up after several tries, it causes the rpm's to read over 7 when I'm only driving 60 mph. It should read between 2 and 3 rpm's. I'm constantly switching the ecm relay plugs to start my truck. The air bag and ipdm ecm relay was not covered under my extended warranty when I purchased my vehicle. This has been going on since I purchased it 4years ago.

The failure occurred multiple times. The vehicle was taken to a independent mechanic where it was diagnosed that that sending unit needed to be replaced. The vehicle was repaired. The manufacturerer was made aware of the failure and stated that the VIN was not included in NHTSA campaign number:: 10v074000 (fuel system, other). The failure mileage was 85,000. Pp.

Electrical System problem #6

While driving on the freeway I noticed that the tachometer continued rising instead of going up and down with the speed. By the time I got home the gauge was facing straight down, stuck in that position. I turned the car off and on to see if it would change the gauge, but nothing happened. Next I put the can in park, set the parking brake and hit the accelerator and the gauge began to slowly move backwards, after doing this a few times the gauge moved back around slowly. After doing this 5 times the gauge is just to the left of the red area. No problems with the battery, it is only 4months old. The transmission felt as though it was shifting propery, and there is not a check engine light on or any other problems besides the gauge.

Electrical System problem #7

This letter is in reference to a previous complaint filed with Infiniti consumer affairs on December 3, 2009, regarding my vehicle shutting completely down, stalled out, not moving in the drive or reverse position at a busy intersection on a rainy stormy evening. This occurrence could have caused a serious accident or worse, a fatality. As a result of police assistance and having my vehicle towed directly to the dealership, to date there are no mechanical issues found by the dealer related to my vehicle shutting down at the intersection. My complaint contains additional serious vehicle issues regarding my headlights, instrument cluster/panel, and the fuse box under the hood. Both headlights on my vehicle suddenly stopped working at the same time. The bulbs were replaced and the headlight fuses were found to be functioning. The instrument panel/cluster light blinks constantly as I drive and the panel/cluster gauges are completely not functioning properly. Fuses have been checked under the vehicle’s hood and results indicate some of the 10 amp fuses are not functioning at all. I am concerned that there should have been a safety recall regarding my 2005 Infiniti qx 56, which appears to jeopardize my safety. There are no legitimate answers or explanations as to why my vehicle’s headlights are not working, the cluster/panel has malfunctioned, or why some fuses underneath my vehicle’s hood are not functioning. As a result of my vehicle’s expired warranty and mechanical failures, I have consumed a great deal of out-of-pocket expenses, including a traffic citation regarding my headlights. I am limited and inconvenienced to driving my vehicle at night as a result of my inoperable headlights which can cause me great harm. I am requesting that my situation be given serious immediate attention and resolution.
