The diesel engine Jeep put in Grand Cherokees, the 3. 0 litre mercedes-benz engine, has a "swirl valve" problem and has since it turned 75,000 miles. It causes the car to not accelerate properly and is very dangerous when pulling out into traffic and going up hills. It also makes the gas mileage to plummet. Repairs were told to me by the dealer to be $5,800. We cannot afford to repair this car. The dealer told us the engine would go 300,000 miles, no problem.
Vehicle suddenly lost power (did not stall) while driving 70 mph on interstate i40 in a construction zone (no access to median because of concrete construction barriers). Engine power did not allow me to drive over 35 mph. Dash board indicator started flashing red (etc indicator: electronic throttle control). Several tractor trailers had to brake hard to avoid running into the rear of my vehicle. Engine is 3. 0l mercedes diesel. Problem appears to be a failed swirl motor due to excessive oil blow by from a defective intake tube with an orange gasket. This mercedes diesel engine was used in Jeep gr cherokee in 2007 & 2008. This particular problem was identified in NHTSA item #1006202 regarding mercedes vehicles but never to Jeep. This situation of loss of power while highway driving could of been tragic. This Jeep 2007 & 2008 problem is well documented in various Jeep forums on the internet. Why is NHTSA not doing anything about it???.
2007 Jeep Grand Cherokee with 3. 0 crd diesel engine. While driving the car began to run rough for just a few seconds and then abruptly stalled and would not restart. This resulted in the loss of power steering and power brakes while driving. I was on an incline (with a trailer in tow) at the time and was unable to move the vehicle until being towed. This presents a very dangerous driving hazard to the driver and the passengers in the Jeep and to any other vehicles nearby. The car was towed to the dealer and today (8/15/2011) I was told this is a faulty crankshaft position sensor. I do know of other 3. 0 crd Jeeps that this has happened to while driving. I have also read that other cars and trucks equipped with the 3. 0 crd diesel engine have experienced the crankshaft sensor failure. It occurs without warning and at any speed.
I am driving a 2007 Jeep Grand Cherokee with the 3. 0 l diesel engine. Complaint: when I was driving on the highway in the left lane my Jeep stalled and as I was trying to change lanes I almost got hit. I lost power and it was hard to steer the car and ended up having to push the car with some help to the curbside. I was not able to restart the car. I know the Jeep has a Mercedes Benz engine just like other mercedes that now I have also heard 2007 mercedes benzes with the same exact diesel engine have already been recalled. Please note that Jeep, with the same engine is having same engine problem and please recall so that people are not in danger. It was a very scary day, I could have been injured or lost my life or my childs life or another family. This was very dangerous and I am not feeling good about this engine on the road. Thank you for addressing this issue.
After driving about 40 miles on highway, then turning onto local streets, all warning lights on dashboard lit up, message board flashed "transmission overtemp" warning, then "check gauges" warning. The vehicle went into limp home mode, no gauges worked, including speedometer. Once shut off, vehicle took a while before it would start again. Had vehicle towed to dealer. Dealer could not replicate or diagnose problem. I believe this is related to the crankshaft positioning sensor problem that prompted a recent recall of this engine by Mercedes Benz (3l crd engine). Chrysler would not acknowledge this problem.
Engine stalled while driving, and then would not restart. Fortunately I was going slowly approaching a traffic light or the stall could have lead to a collision. My 11 month old son was with me, and then we were stuck blocking traffic at one of the busiest intersections in town. I have heard this is a problem with my vehicle, the 2007 Jeep Grand Cherokee crd. We could have been killed had this happened on the highway.
My Jeep has stalled and lost power, putting me in dangerous situations. My Jeep has the same 3l diesel engine which has already been recalled in NHTSA for Dodge sprinters campaign id number : 07v594000 and all 2007 mercedes diesels. Nhtsa campaign id number : 08v006000. I have previously filed complaints. Please recall the diesel Jeeps too!! updated 10/08/0.
Vehicle stalled just as I was getting ready to pull out into traffic on 9/11/07 at about 3,300 miles. I could have been hit by oncoming traffic if it had stalled a few moments later. It stalled again 11/5/07 at about 10,000 miles after I pulled into a parking place at work.
