Does anyone have any knowledge of a class action suite against GM for producing (engineering) defective maifolds? If so, please direct me there. I have TWO (2) vehicles that have been the victims. One with
40K and the other with 50K. Both flooded internally.
P.S. The shop supervisor at my local Pontiac dealer told me... One, he has seen quite a few of these...(So did someone at Chevrolet)..Two, the replacement part has been altered from what what put on at the factory...(I am not sure if the second statement is true. I was pressing him by asking, "should I expect the same failure in the next 40
I don't know of any class action suit, but I'm sure that you are welcome to start one. This is a fairly common problem, we just did two of these yesterday.
The lower intake manifold has been changed...or rather....a small metal pipe that sticks up out of the lower intake manifold has been changed to a smaller diameter pipe. You probably won't have the same failure again, but who really knows with the General's fixes.
On a humorous note, I was told by one of our shop foreman that the DSM (district service manager) mentioned that the budget for warranty repairs for GM Canada had already been completely drained by the end of August. This is the warranty repair budget for the 'year'. Too funny....GM is smack dab in the middle of some of the worst quality control I've seen in years. And/or really lousy/untested designs.
We just had one of those new inline 4200 6 cylinders apart for "noisy" engine. Half of the head bolts snapped off inside the block when removing them. This is removing them by hand....it sounded like a gunshot as each one of them snapped. Fortunately, the cylinders had all sorts of weird scoring and etching marks, so the engine was condemned. If those head bolts would have had to have been extracted....my goodness... I'm glad it wasn't in my bay. That engine is nasty enough just getting it out of the vehicle, let alone having to drill out half the head bolts.
Did it look like the cylinder sleeve broke and slid down and wiped out the rings? I heard something like the sleeves are pressed into to thin of aluminum and something would give out. All I know about that engine is a cross-sectioned one I seen. It did not look like it had enough beaf to it to be even a light truck engine.
No, you are thinking about a different issue with these engines. There is a special policy out, but it only affects a very low number of engines. We haven't seen one yet, but I believe we are slated to replace somewhere in the neighborhood of 60 engines. They are vehicles that fall within a VIN range.
The vehicle we are working on doesn't fall within the range, which is why we had to pull it apart. If you get one within the VIN range, it just automatically gets a new engine after the condition is confirmed.
