Grand Cherokee 8-cyl

  • 63,000 miles


After starting the vehicle it was observed that some of the electrical system, including radio and turn signals were not functioning. Electrical eventually came back. This occurred several other times, generally after turning the vehicle off and then re-starting all of the electrical systems came back on. Approximately 1-2 weeks after the initial electrical issue the following occurred: While driving in a parking lot at approximately 20 miles per hour the engine suddenly cut out after a "clunk" type of sound. After trying several times to restart, the vehicle did start again and drove normally. Vehicle was taken to dealership where code P0688 asd was found. The dealership recommended replacing the asd relay switch. The dealership advised that this relay switch could be the cause of the vehicle dying while driving as well. Relay was not replaced as the dealership informed me the part of on national back order. The electrical cut out occurred again on 6/21/2013 but cleared up immediately upon a vehicle restart. On 6/23/2013 while driving on a highway at approximately 60 mph the engine cut out again. The electrical was also out, leaving me with a dead vehicle and no electronics to signal. After several attempts the vehicle was restarted. I believe that possibly the electronic fuel pump was cut out due to the electrical issue. Dealership informed me that this part is on national back order, which leads me to question whether there is a larger, unreported issue with this part. If there is not a demand for it, why is it on back order, and if there is a demand, perhaps there is an ongoing issue that Chrysler/Jeep is not reporting. Chrysler is claiming that this switch is not covered under warranty.

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

Car stalls intermittently at 60-70mph. Loss of power steering, along with control of the vehicle. Vehicle re-starts up immediately after turning "off" and turning back on in park position. This has occurred more than 15 times in 6 months - with 3 near crash incidents. Dealer cannot duplicate the issue. Currently there are no fault codes indicating a 'manufacturing defect'. no diagnosis after 8 service visits. The issue has been escalated to Chrysler executive group. Flight-recorder returned no data.

In Oct. 2012 the car would not start. No click no nothing. However, the lights, radio, etc. Still worked. If you waited about 15 to 60 minutes it would then start. I took it to the shop and they replaced the starter. It ran fine until April 2013. Then once again it is doing the exact same thing. Now the $638 plus the cost I am incurring for rental car. I purchased the wrap warranty and they tell me that because it is attached to the battery cable it is not covered. I have read all over the internet of hundreds of people having electrical problems all related to this wiring harness. I am not a mechanic but I would think that this could cause a fire. Regardless, Jeep needs to recall these vehicles.

While traveling on the highway at about 70 mph, the engine stalled and shut down. I had to pull over to the side and restart the car to continue. I've had similar issues with this vehicle dozens of times and I fear that one day it will cause an accident when it shuts down on me. The dealer seems to not know what to do about it and I'm scared that I'll get hurt driving the car.

Grand Cherokee 6-cyl

  • 73,000 miles
The moving vehicle inadvertently stalls. The stall has mostly occurred on the highway at speeds of 70-75 mph, as well as on-ramps and off-ramps. The frequency of occurrence is approximately (3-4) times per month. When the vehicle stalls I have to quickly put the vehicle in neutral and restart the engine. Fortunately the engine restarts immediately and I am able to resume driving. The problem was reported to a local (ri) dealership, who was unable to diagnose a problem/defect. I am apprehensive about driving this vehicle, and I am a police officer with extensive training. I will not allow my wife to operate this vehicle.

Grand Cherokee 8-cyl

  • 36,000 miles
I have had an on going electrical problem with my 08 Jeep Grand Cherokee. When I am driving my Jeep at various speeds it goes off. It has happened numerous times at different speeds. On the interstate at 55 miles per hour it has gone dead at night and my headlights, dash and steering all goes out. I have had to shift into neutral and restart the car. It has gone off more frequently just driving around town, no warning happens it just dies. I have had my car in the shop several times and their tests show nothing wrong and when they drive it "they say it does not die on them". it is in the shop now again and has not gone off on them. They put a recorder on my car and let me drive it and said if it died to push the recorder button and it would record the incident and they would know what was wrong. It went off 6 times in two days and I pushed the button 6 times. They said they checked the recorder and it showed no incidents!!!! I know this is a safety concern, I guess no one will do anything until there is a fatality. I understand my VIN# is not included in the recall for the 2008 Jeep electrical problem. I am not sure why.

While driving my vehicle the gauges started to go up and down, the radio went on and off, the turn signals were interrupted, all the idiot lights came on and went out leaving the engine light on. I called my garage and found out the front control modular is going. There was a recall on 2008's but my vehicle was not included due to manufacture date. My vehicle is only 4 years old and was used previously by diamond Chrysler. I have not received any recalls. According to them my vehicle is clean. Now I will have to pay close to $1,000 to get it fixed. If a recall goes out it should go out to all vehicles in case one such as my vehicle gets missed.

When going over speed bumps my vehicle stalls. This is the third time this has happened in the last 2 months. I've brought it to the dealership multiple times. Each time I've been told there is no problem, or that I need spark plugs replaced, or the throttle body needs to be cleaned....nothing has helped!

While driving all my gauges stopped working such as the wipers, speedometer, oil light, all of my gauges stopped working that are controlled by the computer. Couldn't tell what gear I was in while driving. My radio and clock wouldn't work. My blinkers wouldn't work. I had to take it to get it fixed this morning. I surprised this wasn't on a recall.

Grand Cherokee 4WD 8-cyl

  • 51,300 miles
Driving approximately 55 mph on interstate, vehicle suddenly lost power and steering control tightened. Gas gauge went to E, mph went to 0. vehicle started immediately after it came to a stop. Took vehicle to dealership and they could not duplicate the problem. Was not satisfied with having my Jeep returned to me without identifying solution. Mechanic's best guess was that he could replace power module - total integrated power module was what mechanic replaced. Well, Jeep stopped five additional times in last 21 days. Four out of five times, vehicle shut down on a slight decline (neighborhood dip or exiting gas station). Vehicle did start immediately after it came to a stop. Dealership still cannot duplicate the problem. Frustrated with not having my primary family vehicle available.

Grand Cherokee 4WD 8-cyl

  • 32,200 miles
There is a recall (#89275) for improperly manufactured front control modules on certain 2008 Jeep Grand Cherokee. I own one such make and model (bought it used in June 2011), and am being told that I may have to replace my front control module by a service writer at the local Jeep dealer. It would not start this morning at all. Since August there has been intermittent malfunctions in the automatic start, navigation system and power seat settings, and parking assist, too. I am being told separately by the Jeep national recall center that the recall is VIN-specific and does not impact my particular vehicle. Is this a legitimate explanation of fact by Jeep?

Vehicle stalled at around 20 mph and could not restart (engine would not turn over) for several hours. After several hours, vehicle started fine for dealer. Dealer could not find root of the problem. Behavior seems similar to recall NHTSA campaign id 08V059000, but this vehicle is not on the recall list.
