1999 Jeep Grand Cherokee: sudden loss of power

Filed Oct 28, 2015 · Engine · 212,000 miles · NJ

The jeep engine shuts off unexpectedly. This occurs after approximately 25 minutes of driving. It can happen during high speeds on the highway 60 + MPH or during idle when stopped in traffic. This is extremely dangerous as I had to avoid several accidents. The jeep might start immediately after a short wait, or can take a day and start with the same problem. The gauges go off, with the fuel showing empty, then the engine simply cuts off without any prior warning. You lose all power, brakes, steering etc... This is a serious problem that appears to be documented all over the internet without chrysler stepping forward to make the necessary corrections that might eventually save lives. It does this problem, whether you are idle condition, making a turn, traveling a short distance or on the highway in a middle lane surrounded in traffic doing 65. The weather also has no effect as it has occurred during warmer weather and cooler weather. I am lucky to be alive as I recently avoided a rear end collision.

Excessive engine knocking with power loss and abnormal driving capabilites. Sounds like bad internals. Suspension causes "death wobble" at cruising speeds. Engine happens anytime engine is running producing large quantities of smoke from tailpipe.

While driving at 55 MPH, the vehicle lost all power, gauges all dropped to zero. The steering wheel was tight to turn and the brakes hard to apply, had no acceleration while pushing gas pedal down. All lights and radio still was working after getting it off the road turned jeep off would not restart for 3 hours. This has happened numerous times mechanic can not diagnose the problem no codes come up. Have already replaced battery alternator and crank sensor have no idea what is wrong, with three children I am scared to drive this it is unsafe. Also having problems with heat they said heater coil is bad and all motor doors in dash is broke and dash would have to be taken apart to be fixed this is also affecting the A/C. There needs to be a recall as there has been plenty complaints already. This is a death trap waiting to happen.

While driving on the nj trnpke, the vehicle lost power and coasted towards the shoulder. Driver pulled over, and opened the hood, and didn't notice anything. While on the ramp, the vehicle started smoking and the thermometer gauge had begun to rise. The vehicle then bursted into flames . *ak the consumer states that as they got on the ramp, a passing driver waved, and the consumer looked in the rear view mirror and saw the smoke coming from the engine compartment, possible ecectrical system failure.

Several times prior to complete power failure, vehicle decelerated on its own with a small jar as if tapped from rear, then @ 45 MPH I lost complete power, no steering ability, power brakes gone, coasted to stop. No indicator lights prior to power loss, turned off A/C, radio etc. Vehicle re-started. I took to dealer next day. They had it for 3 days, & only replaced battery. Picked up vehicle on 6/28 & 6/30 vehicle shut down @ 45-50 MPH same scenario, took back to dealer and they replaced module-powertrain control. Picked up 07/03, drove less than 10 mi & vehicle started the deceleration problem again.

Transmission slips between 2nd and 3rd gears - loss of power to the drivetrain between 2nd and 3rd gear.

I am an owner of a 1999 jeep grand cherokee limited v8. I have encountered many problems with this vehicle but some have already been resolved under manufacturer's warranty. A couple problems still exist though. One main problem is that my vehicle occasionally stalls out on me at red lights. It idles very slow (@400 RPM) and this is usually when the vehicle fails on me. I'll lose power to the transmission, but all the electrical items will still work, such as the radio and heater. When the engine dies out, the check engine and airbag lights will display. This problem has been brought to the attention of two dealerships but has not yet been resolved. Another problem I have is that I will feel a big clunk when I am accelerating, usually when I first start to drive off. The second type of clunk I feel is when I put the vehicle in reverse to drive. I will feel a big bang like somebody had hit me from behind. This will specifically happen during the shift from reverse to drive. The third problem I encounter happens when I have my heater on. I will have the control settings set @80's and the air conditioner will operate. I do not have the setting at defrost mode. It is in regular mode and when I want the heat, the AC plus the heat will trigger. I would greatly appreciate it if these problems were looked into. Thank you.
