I'd just like to add a few things to the fine products GM has offered. Remember their first attempts at a diesel engine? They put a 5.7 liter converted gas engine in half ton pickups and told people not to tow anything with them. They were dropping like flies so badly there were retrofit kits offered to convert back to gas. These engines didn't even last in cars until they made some mods toward the end of the engines production increasing the journal size by 1/8" to keep them from breaking crankshafts. I had one the last year they produced them. You could look at the earlier and later engines and see quite a difference in them. I did manage to get 350k miles before it let go but had to put a seal and governor kit in the injector pump every 60-75k. Then there were the 6.2 and the 6.5 Liter with turbo that didn't make 100k before they blew. My father gave one back at 85k with a blown engine under the lemon law. When they brought out the Maxi-Pad I looked at one and told the dealer they had been screwing the public with poor excuses for a diesel engine for better than 2 decades, why should I believe this engine is any better than their previous attempts??? They put out overdrive transmissions that dropped like flies also. The aftermarket started offering kits to retro-fit a turbo 350 to replace them. The last transmission failure I had was due to a cheap (new and improved) 3-4 apply piston made of stamped steel with a bonded seal that wouldn't have made a good oil seal but was supposed to be a pressure seal to engage 3rd and 4th. I also found a plastic thrust bearing right behind the front pump. I wonder if the kids they employ are aware of what happens to plastic when you put it in hot oil long enough???? Apparently not!!! I rebuilt the tranny with the old design apply piston and a few other refinements and it has been working longer than the original did. This is why I went to Dodge from GM. They are perfect examples of a company that can build anything cheaper and inferior resulting in superior profits for the corporation. There is currently a class action suit over intake manifold gaskets and Dex-Cool on certain cars with the 4.3L V6 and a few other engines. See Dex Cool Litigation Website. There was also a class action suit against them for the 5.7 liter diesels. If they take over any division of Dodge/Chrysler/Jeep, beware. The whole damn thing will be made of plastic and will go into self destruct mode eventually. They are supposed to be the technology leaders but I guess that means plastics technology. For those not wanting to buy foreign be aware that GM has a long standing relationship with Isuzu going back to at least the 1970's Chevy LUV/Isuzu Pup and now the Maxi-Pad, the Chrysler K-car was at least in part Mitsubishi I believe. Geo was an arrangement with Toyota. You aren't necessarily getting an American car just because you bought it from the
Big3.
Sorry to ramble but thought I'd share some of my GM nightmares.
