Infiniti G37 jerking problems

Filed Mar 27, 2023 · Electrical · CA

Immediately when I started driving, the sensors on my dashboard started lighting up. First the air pressure sensor, then the Tire serve sensor, and finally the key sensor. My turn signals were malfunctioning. They would go on and off without me triggering them. Then every time I came to a stop and accelerated again, my car would jerk back. I eventually pulled over and my car wouldn’t even turn off. I had to put the key fob in the key slot to get the car to turn off. Then, the car would not start back up. I had to have the car towed to the Dealership. When I arrived at the Dealership, they told me that there were two other cars there having similar issues caused by rain water getting into the electrical. Here is the diagnosis they gave me: UPON INSPECTION AND SITTING IN VEHICLE CAN SMELL AND FEEL DAMPNESS FROM CARPET. FURTHER INSPECTION FOUND WATER FROM SUNROOF DRAIN TUBES LEAKING WATER INTO THE BODY CONTROL COMPUTER AND CAUSED ELECTRICAL SHORT CIRCUIT WITH INTELLIGENT KEY SYSTEM AND IGNITION SYSTEM. PERFORMED ELECTRICAL TEST AND TRACED SOURCE OF FAILURE TO THE BODY CONTROL UNIT. (THE BODY CONTROL MODULE CONTROLS KEYS, DOOR LOCKS, VEHICLE IGNITION START, AND TURN SIGNALS), AND VEHICLE LIGHTS). INSPECTION FOUND THERE IS A SHORT IN THE BODY CONTROL UNIT COMPUTER DUE TO WATER INTRUSION. REMOVED BODY CONTROL COMPUTER UNIT AND FOUND WATER INSIDE THE CONNECTOR PLUGS. BODY CONTROL MODULE COMPUTER SHORT CIRCUIT AND IS COMPROMISED. NEED TO REPLACE SUN ROOF DRAIN TUBES TO ELIMINATE WATER INTRUSION INTO THE CABIN AREA AND ALSO TO REPLACE BODY CONTROL UNIT COMPUTER. It’s highly unlikely that there would be 3 cars with similar issues at one dealership on any given day if this was NOT a manufacturers issue. Please help me get reimbursed and start a recall for this dangerous issue. Thank you

On June 4 I pulled into a drive to turn the car around and park. I stopped the car, put it into reverse, and pressed the gas pedal;. The car stalled and I pressed the gas pedal again with the regular force. Suddenly the car accelerated and I felt a jerk and heard a bang as it hit a car that was just backing out of the driveway cross from min. My car was going so quickly that the other driver commented on the speed it was going. My car incurred considerable damage, the rebar was damaged, and I took the car int "collision" for repair. At Collision, I was told by 2 people that Mini had a problem with acceleration. Priori to the accident, my car occasionally stalled when I was backing it out of the garage. I have since been told that this "stalling" or "stumbling" was a signal that there was a defect that could have been fixed.

I was driving my vehicle on a state highway with no breakdown lane, only a 'soft shoulder' going about 70 MPH in the middle lane. There was a vehicle in front over me going about 65 MPH and the furthest left lane was moving closer to my speed. When there was an opening, I signaled and began changing lanes when the vehicle began jerking and losing power. There was a car approaching fast in that left lane and also the vehicle that was behind me in the middle lane began closing in. I nearly caused a three car pile up trying get over to the soft shoulder. These vehicles are equipped with a vq37vhr motor which infiniti equipped with a paper gasket in the depths of the motor called a 'galley gasket'. Its cheap fragile design causes loss of power and for the vehicle to not exceed 2500 rpms which is very unsafe for highway driving as many times it is necessary to safely navigate or even exit the roadway. The paper gasket causes inevitable demise to the motor allowing oil to enter where it should not. This is all before the check engine light even illuminates. Once the light comes on, it will display a code 'p0011' and/or 'p0021' which calls for the variable valve timing solenoid to be addressed. I replaced both, changed the oil, and the car drove fine for a few days then the same thing repeated. After going to numerous shops and them either not wanting to take on the job or not knowing what else the issue may be, I went to the infiniti dealership and was told that I need a new motor. After extensive research, I've come across thousands of owners experiencing the same issue. The more handy ones with time have discovered this 'nissan' cork paper gasket causing the issue. Infiniti designer and manufactured these motors with poor quality gaskets then charge the customer upwards to $3000 to fix the problem they caused through their own negligence or over $5000 for a new motor.

I was driving down the freeway and because of traffic, I had to come to stop. I push in the clutch to try and take the car out of gear and the clutch pedal is soft and goes to the floor. This results in a longer stopping distance and I almost hit the car in front of me. Since I couldn't take the car out of gear, the car dies as I come to a stop. The traffic begins to move again and I attempt to start the car. The car lurches from the starter and the car still in gear. The car does not start, but I am able to get the car out of gear and make it a halfway onto the left shoulder. From here I am able to start the engine but still can't get the car in gear as cars start moving quickly past. Pumping the clutch pedal does nothing to build pressure, but after revving the engine slightly, it seems to build a bit of pressure and I am then able to get the car in gear and very unsafely (max is only 20mph in first gear) make it to the right lane to exit the freeway. I crawl under the car and find leaking clutch fluid that appears to be coming from inside the bell housing. The car only has 50k miles and is only 6 years old. I put myself and my family at risk that day and feel like the failure in the clutch hydraulic system is flawed and is a huge safely concern.

On january 8, 2017, I was pulling into a parking spot in a local hardware store's parking lot and the car started to accelerate on its own accord. I had to press down on the brake pedal hard to stop the car, while all the time the car was still aggressively accelerating on its own. Thinking my foot had inadvertently been pushing on the gas pedal while also braking, I pulled my foot off of the brake pedal momentarily, but this caused the car to lurch forward and actually jump the curb with the front wheels. I immediately slammed the brakes back on and quickly shifted the transmission from drive to park, all the while the engine is still revving and trying to move forward. Once in park, I proceeded to push the start button and the engine stopped. I re-started the car at that point, but the dangerous condition did not return. I have driven the car since this episode with no recurrence, but it is quite concerning to me. I was going to let my sixteen year old daughter drive the car to school, but not now.

My wife was pulling into her parking spot at work with her foot on the brake when the car suddenly lurched forward. She clearly remembers braking as normal when parking and had witnesses standing within 15 feet that noticed the sound of the brakes and the brake lights lit. My wife's head hit and cracked the windshield. In addition to head injuries, she has whiplash and other injuries. The front bumper was badly damaged along with fluids leaking from the engine. The air bags never deployed.

When I am braking and coming closer to a stop, my car gives a jerk along with an increase in engine speed. Sometimes when I brake I can feel the foot brake stuck for one second.

Pulling into parking stall (brakes applied / traveling 5-10 MPH) the car lurched forward twice and stuck a parked full size truck. The car bounced backwards and lurched forward again and stuck the truck a second time and bounced backwards again. The ( off button) was able to be pushed at that time. The brake was fully applied the entire time. This has been the only occurrence. Infinity has not been able to duplicate problem and has downloaded the data base. The formal report will take approx. 4 weeks to complete. No parts have been replaced. Infinities consumer's affair has told us to pickup the vehicle and drive the vehicle despite no explanation or written proof the vehicle is safe to drive. The problem is related to either braking, acceleration or both.
