Selected complaints filed with NHTSA by 2004 Infiniti G35 owners, lightly cleaned up (personal details are redacted by NHTSA).
Car has unintended acceleration that can only be stopped by turning off ignition key. This happens without warning. When stopped and foot on brake car accelerates to top rpm then brake goes to floor resulting in no control of car.
Vehicle was in motion on a city street when the engine seemed to acquire a life of its own and sped up, unresponsive to drivers application of brakes for several seconds.as driver brought the vehicle to a stop, a puff of white smoke emerged from under the hood.
I stopped my my 2004 Infiniti G35 sedan at the end of my driveway, set the parking brake, and got out of the car to retrieve an item left on the ground next to my mailbox. When I walked away from the car, it began rolling. The car rolled off the side of my driveway and into the woods, where it hit a tree, causing considerable damage. Infiniti denies any responsibility for the damage, claiming that the brake is functioning within factory specifications. The following links offer evidence that the parking brake on this vehicle is woefully inadequate as delivered: http://forums.freshalloy.com/ubbthreads/showflat.php?cat=&board=ubb25&number=67788103&page=0&view=collapsed&sb=5&o=&fpart=1 http://forums.freshalloy.com/ubbthreads/showflat.php?cat=&board=ubb25&number=67563340&forum=ubb25&words=parking%20brake&match=entire%20phrase&searchpage=1&limit=50&old=1year&main=67563171&search=true …
While driving our 2004 infinity G35 on the fwy going about 40 MPH (the ground was wet) we felt the track control started to shift side to side, a truck cut in fron us us, which made my husband put on brakes, as he putted on brakes, the driver side front brake locked, which caused for the card to turn sideways and hit the center divider full speed. The brakes after they locked, never stopped the car, the only thing that stopped us was the center divider. The airbags never pop, as we hit the wall going 40 miles per hours. I have taken the car to the dealer recently and had the brakes changed (2 times in 11 months) and the last tme I tood the car I informed the dealer that the brakes felt hard, and they were hard to stop they stated that the brakes will get better with use, and that's how it usually felt after the brakes were changed. …
I drove to baltimore from dc and back with no issues, then turned to go into the alleyway behind my home. All of a sudden, the steering wheel locked and would not turn and all the lights on the dashboard came on, including the brake light. My brake pad froze midway down, stopping the car, but not budging, even when I tapped the gas pedal. I put on and off the parking brake, to no avail. I tried to move the steering wheel around, but could not. Then I tried to turn off the car and restart it, but it took me three tries. When I restarted the car, the brake pad started functioning normally again and the car has been normal ever since. Additionally, nothing like this has ever happened before.
1. Takata recall information site says my car's VIN number has 0 recall. My car is over 12 years old, and I live in florida. Any chance of it exploding in such an old car? 2. When ignition is started, on occasion, car has screeching sound when engine is cold and car is not in motion. Does not happen all the time. Also occasionally when brake is applied, it 'moans'. It also screeched recently when brakes were applied to stop when car was only going 2-3 MPH. 3. Light indicator saying either oil (or water?) is needed is constantly on, for years now, yet mechanic says nothing is wrong... Light indicator computer is faulty. True or false?

The foot brake depresses lower than the accelerator thus causing the motor to accelerate when applying the break. When breaking in an emergency, the side of my shoe caught the accelerator causing the motor to rev up and pushed our car into the vehicle infront of us. Fortunately, we were going slow enough by this time and only the front bumper was damaged. No injuries incurred.
I was traveling at 35 MPH and I was hit by another car in the driver side door and I slipped straight about 100 feet and hit a light pole none of my airbags deployed and my foot was on the brake the whole time and it seemed the bakes did not perform as expected.
While driving at approximately 75 MPH driver was changing lanes and the ABS system locked up, causing the vehicle to spin and hit the center divider and flip over several times. The two passengers and the driver were killed .
