Manifold/header/muffler/tail Pipe problems of the 2007 Jeep Grand Cherokee

This vehicle has a 5. 7 liter hemi v-8. It currently has an exhaust manifold leak because Jeep uses cheap screws to mount the manifold to the engine block. As such, the screws snap causing a leak. This is a well know problem for this engine but Chrysler refuses to acknowledge it and the repairs will be a minimum of $500. Never buy a Jeep!.

Catastrophic engine failure at about 124,000 miles. Luckily in the driveway where I had parked the car after running normal errands. The car would not start up again and had to be towed since the battery was new and the starter seemed frozen. I took excellent care of this car at the dealership and at a top local garage since we bought it. I was stunned that the engine failed without any notice, no warning lights, no noise, nothing. The local mechanic saw "chunks of metal" in the pan. I now need a completely new engine 5 weeks after an oil change due to a design flaw in my Jeep hemi engine. I never received any letter or notification about this apparently well known and relatively common problem. I had every recall performed on this car. There was never a recall for this problem which apparently includes the intake manifold. The response from the dealership was that the hemi is a good engine. Really??? no apologies, no call from the manufacturer. Out of warranty, so it is just too bad for me as a customer. They know the design flaw exists but don't care about the customer. Just their bottom line.

The contact owns a 2007 Jeep Grand Cherokee. The contact stated that the electric turbo warning lamp illuminated. The vehicle was taken to the dealer. The technician diagnosed that the intake manifold swirl valves and motor needed to be replaced. The manufacturer was made aware of the failure. The vehicle was not repaired. The failure and current mileage was 83,000.

The contact owns a 2007 Jeep Grand Cherokee. The contact stated that while driving 30 mph the vehicle stalled without prior warning. The vehicle was taken to a dealer who diagnosed that the exhausted manifold was defective and needed to be replaced. The repair failed to remedy the failure. As a result the vehicle had to be taken back to the dealer who stated that there was carbon build up in one of the valves. The repair performed for the second diagnosis also failed to remedy the failure. The manufacturer was not made aware of the failure. The failure mileage was 89,000 and the current mileage was 89,449.

Engine started stalling while coasting to stops and would occasionally stall while stopped. In time with higher milage the engine started stalling at highway speeds also. No prior warning or dash warning lights would warn ahead of stall. Eventually with higher millage check engine light occasionally would come on while driving but wouldn't cause stalling problem. At 95,000 miles had dealer flash pcm per TSB 18-004-08 for code p0430, power flushed and cleaned engine fuel injection system. Removed and cleaned throttle body on intake manifold and ensured proper minimum air flow settings, flushed combustion chamber to remove carbon deposits. TSB 18-004-08 resolved check engine light from coming on but still have stalling at idle or highway driving. Engine performs as always with no prior warnings before stalls.
