general problems of the 2009 Infiniti G37

While stopping vehicle, braking became non-responsive and engine began racing. Vehicle was extremely difficult to stop completely. After taking foot off of brake pedal, vehicle lunged forward as if accelerator pedal was fully depressed. This has occured on 12/9/12 , 12/10/12, 12/15/12. Infiniti has not corrected problem. This rapid acceleration / non-responsive braking has caused two (2) near miss accidents.

Vehicle vibrates when braking. Dealership found front rotors out of round and replaced them.

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.

Vehicle vibrates when braking. Dealership found all four rotors out of round. Dealership also found rear rotors warped. Dealership cut front rotors and resurfaced rear rotors.

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).
