Grand Cherokee

  • 37,500 miles

A D V E R T I S E M E N T S

In my 2005 Jeep Grand Cherokee, while traveling on a congested road, approx. 25 mph, I took my foot off the gas to slow down. All of a sudden, the vehicle accelerated on its own. Luckily, foot was on the brake hard. I attempted to tap gas pedal with other foot several times while trying to fight through traffic without crashing. I attempted to ease up on brake pedal while trying to pull car over, tapping on cruise control button, making sure that was off. In a state of shock, I actually turned the ignition key off, but the vehicle remained going. Soon after, I was able to reach the side of the road with the vehicle still wanting to accelerate and foot still on brake. This terrorizing episode lasted for under a minute before it ended as suddenly as it started. Due to the shock, I didn't realize I should have put the car in neutral. After a few minutes, I drove the car home very slow and cautiously, still shaking. I did not notice gauges on dashboard at time of the incident. The next morning, the car was towed to dealership. Diagnostic testing, test driving. No codes, no incident replicated. Throttle system checked and cleaned. No diagnosis found, suggest to change floor mats. I have driven vehicle for four years, no complaints. This is the first incident which scared the heck out of me. Vehicle has 37,500 miles on it. Having to pay for diagnostics and towing, we still do not know if it will happen again. My wife and I are both scared! hopefully, it won;T repeat itself.

  • 67,700 miles
On Dec. 21, 2008, while driving down ih-35, my 2005 Jeep Grand Cherokee suddenly and uncontrollably started accelerating. I felt the pedal leave my foot, and pin to the floor. I tried tapping it a few times, then applied the brakes with no result. I had to shift into neutral and pull over onto the shoulder, where I watched my RPM gauge pin at 6000 RPM for approx. 30 - 45 seconds. It finally went back to normal as I was bringing it to a stop in order to turn the car off. This is the 3rd and most severe time in 6 months this has happened.

I own a car wash in belvidere, il and on 4-6-08, we had a customer bring their 2005 Jeep Cherokee in, we put it in out tunnel and ran it through our automatic wash in neutral, and at the end of the tunnel a driver got in, put the Jeep in park..started it, and the Jeep took off racing down a ditch and onto a major street. The vehicle came to a stop when the driver crashed it into a cement light pole. The Jeep is totaled, and there were no injuries, but it came close to running over four customers that were standing, waiting for their cars to be done. This is the second time this has happened with this same Jeep an another wash facility. This is the second one we have had at out site in two years. Help!!

While trying to stop, while my foot was on the brake pedal, the engine started racing and was not able to stop, I ended up hitting the car in front of me, 2 car passengers went to the hospital with minor injuries. Contacted Jeep and car was checked by factory expert at local dealer, nothing defective was found with brakes. This has happened 2 times before this accident. Fortunately, I was able to stop. Also I had to replace all 4 rotors with less than 18,000 miles, complained to Jeep and was told that rotors are normal wear and tear item and how long they last depends on your driving habits. I just heard on tv that there is a recall for brake failure, contacted Jeep and was told no, there is no recall at this time. Please let me know if there is a recall on 05 Jeep Grand Cherokee for brake failure. Eq-10203460-4200. Date received 12/12/07 New Jersey police report. Updated 12/12/07

: the contact stated in April 2006, the vehicle accelerated on its own nearly causing an accident. The service dealer determined the computer system that runs the transmission was the problem. The computer issue allowed the transmission to leak improperly. Also, in October 2006 the vehicle stalled at 30 mph due to all the electric in the vehicle failing.

After filling the gas tank of my 2005 Jeep Grand Cherokee 5.7 liter hemi I accelerated onto the interstate and the car began to decelerate and all the information lights came on and began to flicker on and off as well as the headlights. Vehicle then proceeded to drive normally with check engine light on but not pulsating. Dealer next day could not look at it as I did not have an appointment. After several stops and turning engine off the check engine light went out. Several days late the information gauge lights flashed and received a code message to service electric brake system. Then they recycled and has been clear since.

Local carwash employee entered into a 2005 Jeep Grand Cherokee. When ignition was turned on, the vehicle redlined and accelerated off of conveyor. Employee hit the break with no response. The vehicle collided with another vehicle and went through a towel cabinet and a brick wall. Four employees and myself were nearly killed. I took the driver out of the vehicle and while no one was in it, it was still trying to drive through the wall on it's own. (nothing was touching the accelerator).

I have a 2005 Jeep Grand Cherokee Laredo on 2 different occasions my engine sounds like it is revving at full throttle but I have no power. The RPM does not reflect this. Both incidents have been first thing in the morning and there is no warning. Fortunately I have had enough power to get the vehicle off the road. I estimate my speed to be approximately 5-10 mph. I am hoping that if you have had similar complaints that you can advise me what was done to fix the problem. I have had the Jeep to the shop on two different occasions but they advise me since they cannot replicate the problem they cannot fix it. Thank you for any assistance you can give me.
