| Vehicle Speed Control problems |
While driving my vehicle, it suddenly accelerated without my foot on the accelerator. The rpms increased significantly, and the vehicle went to full throttle, accelerating rapidly without any input from me. I immediately attempted to stop the vehicle by pressing the brakes, but the vehicle continued accelerating. I also attempted to shift the vehicle into park and neutral, but it would not shift into either position. I was forced to turn off the engine while the vehicle was still moving in order to stop the incident. After the vehicle stopped, the steering wheel and brakes locked up. This was a frightening and extremely dangerous situation that could have resulted in a serious accident or injury. I reported this incident and expected the dealership to conduct a thorough investigation to determine what caused the vehicle to accelerate unexpectedly. It is a serious safety issue involving a vehicle that accelerated at full throttle without driver input. I have also having issued with the electrical with the screen flashing on and off the car stating the key is not detected when its in my hand.
The turbo does not kick in and caused the vehicle to not accelerate as needed when initially pulling out in traffic. Infiniti has a software update but they are charging owners to do it stating it is not a safety update but a performance update. This delay in shifting almost cause my vehicle to be hit because the car would not shift out of first gear. This also is not considered a warranty item to them.
On xxx, at approximately 7:30–7:50 a. M. , the driver was traveling northbound on the [xxx] in [xxx] during heavy rain. While the vehicle was moving, it unexpectedly began steering or correcting its direction without the driver intending it to do so. At approximately the same time, the vehicle lost acceleration and the brakes did not respond normally. The driver attempted to stabilize and regain control of the vehicle, but the vehicle continued losing speed and could not be controlled normally. This created an immediate risk of being struck from behind while traveling in the express lanes. The vehicle ultimately collided with the express-lane concrete barrier. No other vehicle was involved. The airbags did not deploy. Police responded to the crash and a police report was created. Medical evaluation was obtained at an emergency room following the incident because of pain after the collision. The vehicle was towed to a collision repair center and remains available for inspection. The insurance company has inspected the collision damage and prepared a repair estimate. The incident was reported to the manufacturer’s consumer affairs department. The manufacturer stated that the vehicle’s behavior was “expected” or normal and stated that the airbags may not have deployed because the impact did not meet the required threshold. However, the manufacturer has not provided a complete technical inspection report explaining the unexpected steering intervention, loss of acceleration, and abnormal braking response that occurred before the collision. The driver does not recall receiving a warning that adequately explained these problems before the vehicle became difficult to control. The exact component or electronic system responsible is currently unknown. I am requesting that NHTSA review the steering, braking, speed-control, driver-assistance, and electronic systems as a potential safety defect.
