Manifold/header/muffler/tail Pipe problems of the 2005 Jeep Grand Cherokee

Exhaust manifold bolts break and allow unfiltered exhaust fumes into the cabin. There are hundreds of complaints at Chrysler about this problem and they will not acknowledge or fix the problem. Bolts installed are 8mm instead of the standard 10mm.

I just had my Jeep inspected and was told that a manifold bolt was broken and would cause other issues if not fixed. Damage to manifold & gasket, etc. ) they also said that this is a common issue with Jeeps chryslers and doge engines.

The contact owns a 2005 Jeep Grand Cherokee. While driving approximately 57 mph, an abnormal sound emitted from the front driver side of the vehicle. The vehicle was taken to a dealer where it was diagnosed that the exhaust manifold bolts were fractured and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 134,000.

I am the owner of a 2005 Jeep Grand Cherokee with a 4. 7 v8. The exhaust manifold bolts (qty 2) on the passenger side sheared resulting in exhaust manifold leak (possibly due to heat or under engineering rust was not a factor). I have made Chrysler aware of this issue as many people have experienced this issue with the 4. 7 v8 found not only in the Grand Cherokee but the commander, and Dodge durango as well. A leaking exhaust manifold can cause engine compartment fires. This issue can also result in toxic fume inhalation through cabin air intake ports. The dealership quoted $1300 to replace (8) bolts that should never fail. When I called Chrysler, they were not interested in my safety, and excused the issue by stating that "cars are just not made like they used to be". I find this ridiculous due to the fact that this issue can result in death, oxygen deprivation, as well as server burn in the event of fire.
