Takata recall... my Jeep had accelerated on its own 5 times now. Two of which I was on M24 which is a very busy road. First time I almost hit a man on a motorcycle as my foot was cramming on my brake peddle the Jeep was still accelerating, I then had to put it in neutral to get it to stop. Pulled over its still reving itself up. I had to turn it off and back on. Today this happened and I almost rear ended a semi truck.

Driving on highway 91 South check battery light came on then check engine and then all warning lights illuminated. Then speedometer, lights and engine shut off shortly after at 65 mph...very dangerous had to coast to the side of the highway with heavy weekend traffic. Towed Jeep to Chrysler dealer where they got code B229 and B1A35. Dealer replaced win module(ignition) and new keys. Seems to be running okay at the moment. Had to pay dealer almost $800. To rectify not to mention the towing and rental costs. This item should be recalled and we should be reimbursed!

Had the N23 recall done on Oct 7/14. The next day while driving low speed, the vehicle completely shut down, without notice or warning. Radio stayed on. Dash lights completely blank. Power steering gone, power brakes gone. This happened twice in same day. In first incident, managed to slowly get vehicle over on shoulder, put in park and restart. Second incident, shut down on busy city road at low speed while driving, stopped, put in park and restarted immediately. Vehicle back at dealer today! wish I had never done the recall work! no problems at all before that.

My vehicle kept stalling like it was running out of gas and I took it to the Jeep dealer. They kept my car for a week and couldn't figure out what was wrong with it.they told me it might be a fuel pump issue but they weren't positive so they asked me to pick up my car and keep a log. The second time it happened I took it back to the dealer and they kept my car for 5 weeks and couldn't replicate the issue. The customer service was awful. They basically told me they didn't know what was wrong and asked me to pick up my car. I picked my car up and the first day I drove it to work it left me stranded on the highway. The car started stalling out and I couldn't maintain my speed on the highway. I had the gas pushed all the way down and I was barely able to get up to 45 mph on a 65 mph highway. I had it towed to a different Jeep dealer which said it was the transmission which I had to pay to have fixed but I think it was related to the fuel pump issue and the transmission blowing up was a result of that not being fixed. The car is starting to have a knocking sound when I drive it again and I'm not convinced I won't be stranded on the side of the road again. It's completely unacceptable that when I had a problem with my Jeep I take it to the dealer and they don't know what's wrong and can't help me. If they don't know, who is supposed to know"? I feel that my children and I are unsafe in this car. It's unacceptable that a car just stalls out of nowhere on a highway and Jeep/Chrysler acted like they could care less. Like it was my problem and not theirs. They inconvenienced me for over 5 weeks and I still don't have a reliable car that I feel safe to drive. Completely unacceptable. Is it going to take someone being seriously injured or killed for Chrysler to do the right thing"

I switched lanes to the right to make a right turn up ahead when my accelerator when into full throttle! I stepped on the brake with 1 foot and nothing happened. I then used my 2 feet and stepped as hard as I could & the engine kept getting loud and wanted to go full speed! I down shifted (my automatic vehicle) into first gear and pulled up my emergency brake and still my Jeep wouldn't stop! the engine was fighting against me. It finally started to slow down just before approaching the parked vehicle up ahead with passenger inside. I was very fortunate (this time) but nearly suffered an heart attack.

I was driving the Jeep and it accelerated suddenly as if the throttle was stuck. The throttle pedal in fact was not stuck and I had to shift into neutral to get it to stop accelerating. After shifting to neutral, the Jeep stalled in the roadway and I ended up driving through my neighbor's yard to avoid pulling out into a busy intersection as I had no brakes or steering. I almost ran over a pedestrian I didn't see walking on the sidewalk. This vehicle has been to dealerships multiple times for stalling at freeway speeds and stalling when driving around town. This has been an ongoing safety concern, especially with the stalling and Chrysler is well aware of the problem. Most recent Chrysler case # is [xxx]. they have replaced multiple things so far and the problem still exists.

Wife traveling with son on fwy at legal speed of 70 mph w/cruise control on, car suddenly decelerated causing a violent maneuver forcing car into neighboring lane and almost crashing. She stated it was as if it suddenly downshifted into lowest gear and brakes applied forcefully. Regaining control she deactivated the cruise control and proceeded to destination at 50 mph. Took to dealership in davis where it was diagnosed as catastrophic failure of the transfer case which was then replaced at the cost of $2842.75. She retrieved car two days later and proceeded to drive back home (distance is @ 178 mi one way). Car repeated sudden deceleration upon entering the fwy and getting up to speed. Continued home due to medical appointments to keep. Kept cruise control off but called dealership to report that replacing the transfer case did not solve the problem. I pulled codes upon her arriving home and found only code 0430 (catalyst system efficiency below threshold [bank 2] indicating the converter not working to specs. Today she was returning to davis to visit with grandchildren and experienced the same situation. At 70 mph car suddenly decelerated rapidly (as if brakes were applied forcefully) and caused her to abruptly move into the lane to her left. She regained control and continued on at 50 mph. The dealership informed her no mechanics would be available until Monday but as she has a flight out of lax to catch early Monday a.M. she decided to continue on to L.a. without using the cruise control and proceeding at slower speed. The power steering pump was replaced on 4/15/2013 at dealerships recommendation due to a leak and the transmission was serviced in addition to having new valve cover and gasket put on. Spark plugs replaced, throttle body and combustion chambers cleaned and PCV valve replaced. Internet research indicates this is a repeated problem with the Jeep Grand Cherokee

There are two main issues: Stalling and no start. Stalling issue - vehicle began to stall on 8/9/10 on a random and intermittent basis while driving at varying speeds. The stalling appears to have stopped after the last service was completed on 7/25/11. The following information relates to the stalling issue. Each date is separate visit to dealership: 8/13/10 - performed diagnostic test, with no fault codes stored. Checked wiring to pdc and front control module. Road tested for 55 miles. Could not duplicate customer concern. 9/2/10 - replaced wireless ignition node - (due to a bind, stick or seize). 10/27/10 - replaced throttle body. Found the throttle body to be binding. 7/25/11 - performed diagnostic test, found a stored code for the crankshaft sensor. Could not duplicate concern. Replaced sensor. No start issue - this is defined as turning the key to the start position but would not crank. Fuel pump would turn on after a few seconds. All electrical systems were fine. Battery was full strength. In all of these cases, the car would start up without a problem within 24-48 hours after the no-start incidents. The following information relates to a "no start" issue. Each date is a separate trip to the dealership. 5/30/11 - vehicle towed in on Saturday. Service technician started vehicle up three times on Monday. Let sit overnight and started right up on Tuesday. Battery tested fine. No codes in system. 7/25/11 - diagnostic scan, replaced crankshaft sensor (see stalling) 7/26/11 - vehicle towed to dealership. Duplicated no-start issue. Replaced engine wiring harness. Service advisor extremely confident that this was the issue. *after speaking with the service advisor today, he had told me that they had replaced several wiring harnesses on the 2007, 2008 G. Cherokee experiencing same issue since my service on 7/26/11.

My parents purchased a brand new 2008 Jeep Grand Cherokee limited. I was driving the vehicle on July 11, 2008 in my neighborhood to pick up some food with my 8 months pregnant sister in law. As I drove the vehicle it accelerated without me pressing on the gas and I lost control and the vehicle hit approximately 3-4 parked cars, I landed in the trunk of another vehicle, on top of it. If it wasn't for the vehicles parked, I don't think the Jeep would have stopped. Luckily no one was hurt badly and the airbags were not even deployed. This incident has really affected me and the way I drive. I do not even like to be a passenger in Jeep vehicles anymore. In January, 2010 my mother dropped her car off at a garage to have it parked. She was called from the garage that the vehicle had been in an accident. The vehicle once again accelerated in reverse and there was damage to the vehicle as well as the garage. Jeep Cherokee's are extremely faulty, always in the dealership with some issue. This is not a coincidence. This needs to be taken seriously. People can lose their lives if these vehicles are not recalled.
