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.
