Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Grand Cherokee 4WD 8-cyl

  • 51,235 miles


While driving engine shuts off with no indication of why. No stored computer code. Engine loses all power and dies. Must stop vehicle then shut ignition and restart. Truck would start then die.. that happened ten times.. and finally started. Gas tank was three quarters filled and weather was good. Battery is in good working order with proper voltage and charging system is in working order. This is the third time this has happened since I purchased the vehicle as a new unit. The second time it happened I took it into the dealer and they replaced the computer harness as they said it had a bad connector. But the problem is now back and I feel a loss of control resulting in crash and or death may result. [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

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.

The engine stalls intermittently from time to time shutting the car down. It usually happens while coming to a stop or at rest. In September of 2012 it happened on the highway going at 65 mph and I had to bring the vehicle to the curb to restart it. It always restarts easily. I have taken it to the dealer and they can not figure it out.

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.

The contact owns a 2008 Jeep Grand Cherokee diesel. The contact stated that while driving 35 mph, the check engine warning light illuminated. After inspecting the vehicle, he noticed that the oil intake tube was leaking oil into the intake air manifold and going into the engine. The vehicle was taken to the dealer where the contact scheduled an appointment to have the intake manifold and the air intake hose replaced. The vehicle was not repaired. The manufacturer was notified who lodged a complaint for the contact and offered to pay for one third of the repair costs. The VIN was unknown. The failure mileage was 106,726.

I started the Jeep and traveled normally for about a third of a mile on local streets. The problem started when I turned onto a collector street from a local street applying full throttle. When I lifted my foot off the throttle pedal the Jeep kept accelerating. The electronic throttle control warning light went on. I stopped the car by applying the brake and putting the transmission in neutral. The engine continued to rev at about 4000 RPM with the Jeep stopped. I turned off the Jeep and checked the position of the carpet protector to make sure it was not interfering with the accelerator. It was not in a position where it could overlap the throttle. I also checked the accelerator pedal and found it operating normally in terms of position and action. I turned the engine back on and the Jeep reacted normally for the remainder of the trip. Dealer not able to replicated but reported error message that both brakes and accelerator were both depressed. Also reported that carpet was not involved.
