Gas Recirculation Valve (egr Valve) problems of the 2007 Jeep Commander

I have owned this vehicle since new and have been experiencing infrequent and usually momentary engine stalls while driving at highway speeds for years. Each time there was a slight clunk sound and lurch forward - as if the cruise control had just disconnected, and within a second or so everything would be back to normal. But on a recent trip I had three incidents over two days which were much worse, perhaps because they all occurred at temperatures around 0 degrees f. Or below. In two incidents, while driving on an interstate at a steady 75mph, instead of the engine immediately recovering, it took long enough that that the vehicle had slowed down to 30-35mph before the engine restarted itself. In one incident also while driving at a steady 75mph on an interstate the engine did not recover and I had to pull off onto the shoulder and come to a complete stop with no power. I turned the ignition off and then on again and the engine restarted immediately. I had no loss of electrical power during these incidents, and I have nothing dangling from nor could I have bumped the ignition key. I have always maintained the vehicle according to the service schedule and have had all recalls performed, with the exception of the latest one for which the dealer still has not received the parts from Jeep. I took the vehicle into a Jeep dealership the same day as the second and third incidents and they said they could find nothing wrong. I asked them if possibly the power controller module recall needed to be done a second time, and they responded that Jeep would not permit that.

Vehicle continues to stall. At 40mph, engine surges then drops in rpm. Drops rpm to the point of stalling. Idle air control (iac) valve, throttle position sensor (tps), and exhaust gas recirculation (egr) valves have been replaced simultaneously with no change. Only way to drive is to manually shift to keep rpms above 2,000 while driving and to use both the brake and accelerator pedals to keep rpm above 1,200 when at stops. No obd2 service codes are ever triggered.

The contact owns a 2007 Jeep Commander. The contact stated that while driving 25 mph, the vehicle stalled without warning. The failure recurred numerous times. The vehicle was taken to a dealer for diagnosis where the transmission fluid and gasket were replaced however, the failure recurred. The dealer then replaced the exhaust gas recirculation valve but again, the failure recurred. The dealer then cleaned the throttle body but to no avail. The dealer was unable to determine what was causing the failure. The manufacturer was notified but offered no assistance. The vehicle was not repaired. The failure mileage was 124,000 and the current mileage was 128,000.

While driving, the engine will suddenly die without warning. All power steering/brakes are lost. It will restart immediately. This is an ongoing, but random problem. The only code that is recorded refers to the ignition relay module. To date the egr, ignition relay module, and crankshaft position sensor have been replaced. The problem persists. This problem represents a severe safety issue, as a loss of power while pulling into traffic could have catastrophic consequences.

I own a 2007 Jeep Commander. Shortly after purchasing it, I was driving down the highway that runs through my town at about 40 mph and the vehicle stalled out. I tried to give it some gas to go but I kept decelerating. I shifted my gear shift to park, shut it off and restarted my car and it went back to running normally for a couple of days. It happened 4 more times before I took it back to the dealership. They told me that it was a computer error and they corrected it. Two weeks later, I left my driveway and was heading down my street and my car started bucking uncontrollably. I came to a complete stop and put my car in park and waited a few seconds before shifting back to drive. I came to a stop sign a few blocks later and my Jeep stalled out again. This has happened about 4 or 5 times since I took it to the dealership. I'm afraid that this vehicle is not safe for me or my family and I am starting to regret this purchase.
