2005 Infiniti QX56: check engine light

Filed Sep 3, 2019 · 55,000 miles · FL · crash · 4 injuries

While driving straight on interstate I-95 during rush hour at approximately 30 miles/hour, I pressed on the brakes and the pedal dropped down and started making a weird noise (like grinding sound) and the car wouldn't stop. The ABS light turned on, check engine light turned on, the pedal lost pressure and the brakes locked up. I ended up in a crash, rear-ending the vehicle in front of me. The car has now been repaired from damages from crash but mechanic found no problem with brake system. Abs sensors, calipers, disks and pads where changed as precaution but problem reappears from time to time and seems to reset when vehicle is turned off and on again (brake petal raised back up, grinding sound disappears and the check engine light and ABS light shut off). I visited two infinity dealers and both of them mentioned that it was a recurring problem with this model car and the problem was an issue with the master cylinder's design.

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.

While driving ,I pressed on the brakes and the pedal dropped down and started making a weird noise kind of like loose metal parts and the truck wouldn't stop. The ABS light turned on. It felt like the brakes locked up . I managed to pull to the side of the road and shut the truck off. I turned it back on and it seemed to reset the system. Brake petal raised back up and the check engine light shut off.

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 properly, and there is not a check engine light on or any other problems besides the gauge.
