One monday the 6th driving north. It was raining. So, I had full 4wheel drive engaged. A car cut me off. I was on the transition from the 5 n to the 55n. A car from the left lane cut into my lane to try and exit onto 4th street. To avoid an accident I slammed on the breaks and veered right. But the car would not stop. I pushing down on the breaks as hard as I could. The car was still accelerating and did not slow down. Trying to obtain control over the vehicle I "fishtailed" from going right back to left and hit the side of the car and then hit the center divider. The car kept accelerating and I hit the center divider and flipped around. I was then facing opposite traffic towards the divider. I threw the car into park and held the breaks strong. The back wheels were still spinning out. I look down and the keys were not in the ignition. Luckily, I had a spare key in the center console and shut it down. I found the keys on the ground but not anywhere near the pedals. I talked to the dealer and they said they had never heard of it. The only thing they could verify is that the key could come out wile the car is still on. According to them this happens as the key wears down or gets old.

A few instances have occurred where I will be driving and the vehicle engine will immediately shut off as the vehicle is in motion. The electrical components (radio, headlights, dashboard, etc) still function but all gauges stop working. I then have to pull over, put the vehicle in park, and then restart the vehicle. It will then start up right away. On a couple of occasions, the vehicle engine has started back up on its own without me doing anything and drives fine after that. This seems to occur mostly when I release my foot from the accelerator but has happened when I am trying to accelerate. Has only happened when driving on city streets, never on a highway.

The vehicle was running and stationary in park. When the vehicle was taken out of park and into reverse it started accelerating backwards out of control. The driver pressed all the way down on the brake peddle which did not stop the vehicle. While in the midst of a collision he then put the vehicle in park and turned off the ignition. This took place in a parking lot and the vehicle went straight back into a fence.

I filed original oct 4 2016 the federal safety agency complaint and also objected to restriction the federal safety agency imposed upon complaint (2000 characters in total, and total mb of attachments 5mb or less) because oct 4 2016 complaint is insufficient, incomplete. The federal safety agency investigation requires more information from me (reports, testimony, dozens of critical police photos) necessary for the federal safety agency investigation of my complaint. On oct 4 2016, I demanded the federal safety agency investigation unit contact me by email, so that I may document data my submission to the federal safety agency, as part of my complaint. To date, the federal safety agency refuses, it has done nothing to investigate because the federal safety agency stonewalls me for information. The federal safety agency investigation units endangers public safety with deliberate lack of data, resulting in bogus non-investigation. On oct 11 2013, 2002 jeep grand cherokee laredo, VIN no [xxx], had vehicle malfunction event, unintended acceleration, high speed start, high impact and high energy collisions, defective btsi (brake transmission shift interrupter), no brake throttle override, no safeguards to stop vehicle, high rate of speed crashing over and over, in throttle wide open, no software or hardware upgrade to stop or prevent unusual acceleration while in park, inability to brake vehicle to stop at such high rate of speed. Tires vaporized, chunks of rubber broke, metal rim remnants of tire skidded sidewalk and street, in series of horrific collisions, documented by photos and reports which the federal safety agency deliberately refuses to acquire from me as part of my complaint, to manipulate the outcome of bogus and deliberately flawed pseudo-the federal safety agency investigation. Due to height mismatch square box jeep and subcompact cars, jeep was battering ram against subcompact cars effectively without impact bars (bars to low) in such malfunction event, wreck subcompact cars, endanger lives and health of occupants of small cars who absorb impact (instead of distributed forces via impact bar), grave collisions.

The driver may be hard of hearing, may have been distracted to hear the noise or know comes from her car, may have had windows shut and been insulated from the sound, but she changed gear from park to drive as the tires were spinning as observed by witnesses who saw or heard those tires spinning while the car was in stationary position. Jeep speed forward about 70 feet to rear-impact my car and crush the rear of car inward. It distorted frame from rear to front or car, and rear impact caused damage to front of car. Prior to impact, my foot depressed hard on brake because I braced or stiffened hard for impact, when I heard the squeal of tires of stationary car nearby, and people leaving a carnival were nearby. After jeep crushed my car inward, it accelerated again against my car and my efforts keep the brake pedal down, and it propelled my car forward, and then continued on its path of destruction. It wrecked my car, itself, another car, and collided with a another two cars, it hit pedestrians, caused fatality, caused injuries, knocked down parking meters, skidded dozens of feet, broke off its front tires in chunks, skidded its metal rim because that was all that was left of the tire, skidded pieces of rubber of tire, and finally got stuck after last impact, while its engine revved and its tires spun, causing yaw scraping of tires on sidewalk. _police dept found the btsi defective, and the skid marks show that the brakes were ineffective or inoperable as jeep's engine continued to accelerate. Jeep driver ran from it after it got stuck because she thought it would explode. The wheels stopped spinning when the motor got shut.

On march 8, 2016, while driving northbound on interstate 49 in harrisonville, mo, the engine speed raced when taken off cruise control. The jeep stayed at highway speed -- above 60mph -- and even pressing the brakes did not slow down the jeep. The only way I was able to get the jeep under control was to turn off the entire engine ignition. Only by exerting effort to overcome and compensate for the loss of power steering and power brakes was I able to coast to a safe stop off the highway. The tow operator who responded attempted to start the engine but found the same result ' runaway engine revs. The jeep was towed to dealer service department that evening. The next morning, service advisor investigated and determined that the throttle pedal was stuck down to the floor. He loosened it by manipulation. The throttle butterfly valve was found to be stuck in the open position by a shredded piece of rubber that flaked off the resonator body intake connector. Service department performed: 'rubber from intake seal stuck throttle body. Removed debris'. The technician showed me the piece of shredded rubber and gave it to me. I kept it, and the entire defective resonator body, in my possession. There may be other reports of runaway engine revs but this instance seems to be related to the design of the resonator intake pathway. Although my jeep has 246,289 miles on it, the defect was not a result of wear but seems to be result of defective design. The intake air pathway is subject to shredding rubber parts which can come loose, enter the intake air pathway and block the throttle butterfly. This seems to be an unnecessarily hazardous design.

At two occasions the car suddenly accelerated as if the gas pedal was stuck. The accelerator was not obstructed by any carpet. The only way to slow the car down was by placing it into neutral and turn off the engine. After turning it back on it was still at high RPM ~5000. Some time later the problem resolved it self. After many days at the jeep dealer the final diagnosis was that the issue cannot be duplicated and that the dealer refuses to do any work on this car.

I work at a dealership washing cars. We just sold a 2002 jeep grand cherokee. I was running the jeep through the carwash. My foot was on the brake, and suddenly the vehicle accelerated propelling me into a wall, and the airbag deployed. I was injured in the accident and went to an urgent care.
