Grand Cherokee

  • 55,000 miles


Sometimes when I drive the engine feels like it stalls out and my RPM's don't move, all the boxes around prnd light up and the check engine light comes on. I have to pull over and put the car in park or sometimes I have to turn it off. Once this is done the car continues to drive like nothing happened but the check engine light will stay on for a day. Sometimes it happens on the highway which is very scary to just drop speed down to 40. I have read many blogs about this issue. It happens at random times.

Grand Cherokee 8-cyl

  • 62,214 miles
This is a 5.7 hemi engine with 62200 miles. I had driven into a 7-11 parking lot and almost came to a halt deciding whether to park on the right or left. Decided to park on the right. Car was at around 2 miles per hour, lifted my leg off the accelerator to hit brake, when the car suddenly accelerated, climbed over the sidewalk, sliced and felled a tree and rammed into a laundromat. Brake was applied to the point of literally standing on it with whole body weight but car did not respond. Finally the car came to a halt although engine was making revving sounds for a few more seconds. Luckily nobody was inside the laundromat. Air bag did not deploy even though the front was badly damaged. Police report was filed. Cop was also surprised air bag did not deploy for this hard a crash. The car has been owned by me since new for 7 years and this has never happened. Insurance sent a special technician to check, but nothing could be found. Car is more than likely totaled at this point. Please do something about this, someone can get badly injured for life, or deaths can occur.

My 2005 Jeep Grand Cherokee started acting up about a year after I purchased it and has progressively gotten worse and worse. It has problems shifting and identifying what gear it is in on a daily basis, for example when I put it in drive from park prnd will all be illuminated like it doesn't know what gear it is in and it will make a loud thud sound. Then when you drive it won't shift from first gear and will rev up or it will get stuck in 3rd gear and won't down shift. Sometimes it will be driving normal and when I stop at a stop sign and then go to pull out into traffic it will stall right in the middle of traffic and I can't get it to snap out of it! it will also decide that it doesn't know what gear it is in while I am driving on the expressway and will start to rev up and freeze on me. This is very unsettling and dangerous and could defiantly cause a serious accident. From what I have read in other reviews many people have this same problem with their 2005 Jeep Grand Cherokee so it doesn't seem like just a coincidence to me and something should be done. I have taken it to different mechanics and no one can give me an answer as to whats wrong or how to fix it.

I own a 2005 Jeep Grand Cherokee that has been stalling on me. I looked on youtube and there are other owners with same situation. It has stalled on me and my fiance about 10 times in traffic and at sudden stops. I was going 40 miles an hour on a busy street and it just died in the middle lane. I know Chrysler had a recall or bulletin on the newer ones but this is more wide spread then they would like to attest to. There are several other complaints of same situation just type Jeep stalling on google and you will see. I was almost in a collision recently and need this resolved please help.

Grand Cherokee

  • 37,500 miles
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.

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.

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.

Grand Cherokee 4WD

  • Automatic transmission
  • 15,550 miles
: 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.
