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.

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.

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.

2009 infiniti g37x coupe is experiencing dangerous surges in acceleration upon braking, the transmission is jerking and going into "fail safe mode" (meaning suddenly the car is stuck in the highest gear), the rear differential is clunking and jerking as if the car is going into awd mode at times it should not be, and quite frankly I am now becoming scared of the car. It has 3800 miles on it. I took it into the dealership on friday and was told there are a couple of known issues with the transmission but no fix. They also are calling hq on monday to talk about it. I do not want to leave my car to be driven around erratically as they try to "break" it as that will cause further damage to the transmission and engine as well as put more miles on the car. Infiniti service agreed that remapping the computer would most likely take away the specifications of the car which are what they market and I bought the car for (horsepower, acceleration, "same as a bmw". If they have to gut the power of the car to fix the problem, I feel this is false advertising and the car is not what I contracted to purchase. I am on the verge of watching my resale plunge before the car is even six months old and believe infiniti should have to replace the vehicle. This problem is happening repeatedly everytime I drive the car. See notes below: 1. Central computer clearly failing - had to be restored yesterday. 2. Reaf diff clunking in and out of awd loudly and with a jerk and at unexpected times 3. Surging rpms as much as 5000 upon driving 4. Surging rpms and acceleration upon braking (3000 RPM) 5. Hanging instead of downshifting 6. Very jerky downshifts 7. Tranny went into failsafe at least 3 times now (meaning no gear below 5th is available at any time).

2009 infiniti g37x coupe. 1st gear is exceptionally slow and causes dangerous acceleration problems in certain situations. The transmission jerks when up or down shifting. When I took my car to infiniti for service I was told that infiniti hasn't released a software update or recall for this problem yet but that they've been receiving numerous complaints about the problem.

A few days after I bought a new car with electric steering wheel, I noticed a jerk on the steering wheel when I passed a speed bump and at times I feel like the steering wheel jumping on me at acceleration. A few weeks later I found the origin of the problem. The electric steering wheel does not lock in place securely. It will have to be push manually to secure it. If you drive away and forget to secure it manually that is when the jerk occur into the situation I described earlier. I brought it back to the dealer and take it in for repair under warranty, in the process taking out the whole steering wheel assembly and put it back together and told they cannot find any problem. They concluded that 'compared to other similar models they also have a slight play of the steering column. This is normal characteristic of this year and model vehicle". I got in touch with infinity consumer affairs but after a few days they came up with the same conclusion. I think it is the responsibility of the dealer to inform the consumer of this kind of " characteristic " before the consumer make a decision. Is there a defect or safety issue involve in this situation? Thank you very much.
