Intermittent stalling issue. Initially the vehicle starts and runs fine. After stopping or extended driving duration the vehicle will random start stalling and check engine light flashes and dings. This will last for a few minutes sometimes and other times the entire trip. The last few times this has happened we were nearly rear ended and pulled over until it was somewhat drive able. I am terrified to drive it at this time for fear it will cause an accident. This has been an ongoing issue for a few years and has recently gotten worse. We've taken the vehicle to the Jeep dealership several times and have had numerous parts replaced but nothing has resolved the problem. The last trip to the dealer they said they could not replicate the described issue. With the use of a scope and code review, my husband has taken to replacing smaller, simple parts in hopes of a simple solution. . . . Spark plugs, 02 sensors and catalytic converters. Nothing has helped. Please help resolve this issue. Seeing all the other similar complaints, how many does it take to start an investigation or recall? it's a shame an accident it what it may take to attract attention to this issue.

Just had the eniter exaust system replaced due to the cats were plugged . Replaced cats and all O2 sensors with factory oem's and now the car give 3 different codes , p0141, p0138, p1499 . After the codes showed up took back to shop and had to replace all the O2 senors again to the tune of $500. 00 plus labor. And went to drive and get tested only to fail again, for bank 1 sensor 2 high voltage detected. Now shop is telling me there was a problem with the pmc and it needs to be replaced to the tune of another $450. 00 plus labor.

I purchased my 05 Jeep Grand Cherokee 3. 7l v6 with 79k miles on it June 21, 2016. In July of 2017, it started to bog down with a constant shutter when starting up and accelerating, the cel was also on. I took it in to have the cel checked out and it was showing 22 codes saying that the O2 sensor had a high voltage circuit. Upon examinng and testing the O2 sensor there was nothing found to be wrong. A couple weeks later the cel came on again, but this time it showed the same O2 sensor was running lean and rich at the same time. I replaced the sensor at that time. Now it is showing another code p0430 and the timing chain for the electronic shift transmission is jumping. I was informed this happens to these transmissions all the time and there is no repair for it. All I can do is drive it until it goes and buy a new transmission. This is not fair.

The contact owns a 2003 Jeep Grand Cherokee. The contact stated that the vehicle stalled intermittently without warning. In addition, the vehicle failed to start. The vehicle was taken to an independent mechanic, who replaced the alternator, the fuel pump, the oxygen 2 sensor, and the cam sensor, but the failure recurred. The manufacturer was made aware of the failure. The failure mileage was 121,000.

As with many other posts, the vehicle just shut down while driving on the parkway. Pulled off the road put the car in park restarted , waited a minute drove another 20 miles home , no problem. This has happened before in the driveway, or just leaving the house but never on the road. Have replaced ignition switch, both O2 sensors distributor cap, rotor and wires. Fuel pressure is good . Don't expect a fix from Chrysler , there are many posts here and online with no fixes. Just thought I'd add my experience to the mix. Time for a new car!.

The first month or so, my car would randomly die on me, whether I was stopped at a red light, or driving, regardless what speed I was going. I was able to start the car up immediately afterwards and continue like nothing happened. A few weeks later it wouldn't start at all. Called mechanic, he changed the coil. Drove great for a month or so. Then it started doing the same thing. Took the Jeep to the shop. Had fuel filter, fuel pump put in. Ran good for a couple of weeks before it started all over again . Progressively got worse. This time before it died it would buck violently a few times due to dying and starting itself up while driving, accompanied with a really weird odor, like rotten eggs. I then pulled over, turn the car off and check to see if my car was on fire (not). Started the car and drove home ,(7 miles). The next day in the process of taking the Jeep to the shop, the Jeep bucked on and off 3 different times, the smell was intense when a glowing fireball launched out from the rear the size of a baseball scattering all over the freeway. At this point I pulled over and shut the engine off and ran away from it. Called mechanic he drove the Jeep to the shop 20 miles. In this process Jeep died 2 different times in which it took a while before it would start and drive again. Had cat converter and O2 sensor put in. Drove good no problems for 2 months or so. Problem came back mechanic took the new cat converter of . I drove it for a few weeks until it died now it is parked.

My vehicle stalls when it is hot outside. I have had the coil replaced then I had the catalytic converter replaced and O2 sensor and it still stalled on start up. I took it to the dealership and it stalled and they told me it was my fuel pump. I spent 965 on a fuel pump I didn't need because it is still stalling and they have no clue why. I seen this problem on mean forums. I think the dealer should be aware of this problem and should know how to fix them not make someone spend a thousand dollars on a might.

While driving at 30 mph, the vehicle stalled. When this occurred, the steering wheel locked up and the brakes failed to function. The dealership indicated that this was caused by an electrical system sensor failure. The consumer stated the engine light illuminated and apparently the problem was the oxygen sensor, also the monitor light on the dashboard blinked which indicated there was a rear lamp failure even though there was no failure.

Engine repaired eight times due to fuel pump, spark plug and oxygen sensor failures. Yh.
