My 2007 trailblazer ss has a manifold exhaust leak. The bolts are broken on the left front of the head and back bolt of the head on both sides. We are getting exhaust gas in to the inside of the truck. This could cause carbon monoxide poisoning. To the driver in the vehicle, this is very serious condition.

The vehicle vibrates heavily while in idle. The car will be in the drive position at a stop. The car acts as if it is about to stall out. Which presents a huge hazard with children in the car. We have replaced the engine mounts,spark plugs, coils, boots, intake flush and performed routine maintenance. I have read that numerous trailblazers have encountered the same issue with no resolution! My biggest fear is for a car to stall and an injury to occur a a direct result.

Vehicle stalls and shuts down everyday. Sometimes just stalls then accelerates, sometimes shuts off and I can switch to neutral and restart while coasting. Other times I get shutdown warning light and engine will not restart. I have to coast to the shoulder and wait. Engine will then struggle to restart and engine shakes violently. I wait a few minutes and it will start and run fine, sometime with check engine light on, sometimes not. Rpm gauge works sometimes, sometimes not. At time there has been no response when turning key to start. On going issue!! Crankshaft position sensor has been replaced 3 times, and issue still persist. Major safety issue!!
