Engine Belts And Pulleys problems of the 2007 Jeep Commander

Engine does not start sometimes, have had recalled ignition put in already. Then it stalled on highway, had it towed to mechanic, couldn't get it jumped. He took off serpentine belt and showed us engine was locked up. It has a 5. 7 hemi in it. I get all fluids changed when I'm supposed to. Change oil and filter religiously with best oil and filter available . Mechanic even said all fluids looked great. He can't understand it. This vehicle has had numerous problems, from leaking weepholes in son roof to drivetrain, not wanting to start and stalling when ever to now a seized engine!.

Vehicle shutting off when stalling or at a stop driving down a city street with vehicles behind me. Idleing high when turning on or driving. Just had some thing fixed and issue still not resolved seems to be ecm/pcm possibly. Some sort of water entrance unsure where from had windshield reinstalled and I still get puddles on my driver and passenger feet. Back set belts keep braking was told this is a defect when seats are layed down seat buckles break and need to be replaced which is a safety issue with my children since I have 4 and need these to be functional they have been replaced 3 times and am now told it's a defect.

I was driving my 2007 Jeep Commander, 5. 7l hemi at approximately 25 mph on interstate 16 at approximately 2200 hours with my two minor children seatbelted in the the back. We were approximately 150 miles from home. There was heavy traffic due to a holiday weekend, road construction, and rainy weather. I recognized a problem was occurring because I could not accelerate, and my attention was diverted from driving because I was trying to figure out what was happening. I realized that the engine had cut off without warning. There was no power to anything, and the vehicle was very hard to steer and to stop. I pulled over to the side, placed the vehicle in park, and tried unsuccessfully to restart the engine. I was able to check under the hood and I found that the oil level was in the normal range and the oil appeared clean. The antifreeze in the reservoir was in the normal range and there was no bubbling. The transmission fluid, power steering fluid, and brake fluid were also within normal ranges. After another try, it restarted, then there was a loud metal clanking sound then copious smoke coming from the tailpipe, then the engine light came on flashing. The temperature gauge registered normal. I turned the truck off and started making phone calls with thunderstorms and severe lightning complicating the situation. We arranged for a tow truck to transport us to a nearby hotel, and the next day I towed the Jeep back home using a uhaul truck. Mechanics have determined that a piston head is damaged and cracked and the Jeep is currently in the shop having a new engine installed. They did not find an obvious cause for the damage to the piston. There are two significant problems: the engine stopped without warning, and the engine failed prematurely. It is unknown if the problems are related to each other.

Car stalls when driving down the road. The drnp dash lights all light up at the same time and the car shuts down for a couple seconds, then it resumes. It has happened several times randomly in the past. Today, it stalled 3 times on the highway on my home from work. I had to pull over and restart the car. The check engine light finally came on today. The seatbelts also have broken several times. I've replaced 2 separate seatbelt cases (the outer cover) in the past year. The middle, second row seatbelt is locked up and currently unusable. When I bought the car, the first time I put up the 3rd row seat, the seatbelt was crushed by the seat and broken. And, the back seatbelt is currently broken again (which I have only used the 3rd row seats twice since owning the car), I plan to have them repair it again when I take the car in to get the check engine light checked :(.
