Tech during an annual inspection found the rear Diff. Carrier cracked and crumbling apart into small pieces. There was evidence of fluid leaking onto the rear exhaust.

First my engine went out; replace with used engine $5,000. One cv joint went out; replaced $1400. Differential bushing went out; auto shop said he can't find bushing; has to replace whole differential $3,800. I'm sure I'll have to replace the other cv joints soon. This car has 128,000 miles on it. How does an engine and turbo gets ruined? that damn car was $21,000. Now the repairs are almost as much as the stupid car.

The non return valve in the intake either broke or fell off( apparently defective) causing my vehicle-??s check engine light to come and causing multiple error codes. As a result of this defective part it cause my vehicle to vibrate violently, the lost of power, and ultimately stalling out Nearly causing me getting involved with a very serious accident. As a result of this incident I took my vehicle to the nearest mechanical shop had it diagnosed showing multiple error codes and ultimately revealing a missing part ( A rubber nipple ) which was supposed to be inside of the intake. As stated above the check engine light did come on one week prior to the above conditions as a result of this missing/defective part. I had tried on several occasions with the dealership where I purchased my vehicle from to have the above problem resolved with negative results. My mechanic has confirm with me that this is not the first time he has seen this part missing from other GM vehicles with the same type of engine. I did research about my issue and found numerous reports of this with the same type engine in it since 2012, Also my mechanic was told by one of the service members of the dealership that they were aware of this problem obviously this is not the first time, but they refuse to have my car towed and wanted me to pay an additional $140 again to get the car diagnosed. The car was rendered unsafe to drive due to the fact of the above problems regarding this defective part. This needs to be addressed, there is no doubt in my mind that someone will ultimately die from this continuous problem with these engines with this particular part. I have kept all the parts that were taken off of my vehicle for further inspection especially if the NHTSA wishes to inspect it. I am appealing the decision from General motors concerning this Replacement part/ parts that I Purchase to render my vehicle safe and operable.Replacement parts are all GM products !
