The first new car I bought was a 89 S-10 Blazer 4x4 with the 4.3L. It was junk. At about 30,000 miles it blew the engine so bad that some of the rods came through the hood. It took 6 months, a lawyer, and many phone calls and letters to get it fixed. All this time I was on my own for a vehicle to drive and still had to make the payments on it.
Less than 4,000 miles later it locked up the transfer case while I was going about 40 mph. The drive shaft snapped and dug into the asphalt and nearly took the rear end off the leaf springs. Once again it took 6 months, a lawyer, and the same run around to get it fixed.
At about 500 miles prior to the 36,000 mile warranty running out I took it into the dealer and had them go over it. They found many problems including a leaking master cylinder, a bad cad converter, and a cracked exhaust manifold. I believe the manifold was screwed up when the drive shaft snapped because it ripped the exhaust out from under it.
I traded it on a Toyota 4 cylinder 4x4 truck that would out work the Blazer any day of the week. Especially the year it sat during my 3 years of proud ownership. I drove the Toy for 160,000 miles with not one problem other than a bad plug wire and a replacement of a $20 slave cylinder on the tranny. It only had 3 sets of tires and 2 sets of brakes. It did rust out and I traded it on a Civic that I drove for 2 years with no problems at all. I then started buying Ford Trucks which I have now owned 8 since 1997 with nearly no problems other than a power window, a bad dash cluster, and a few recalls.
I broke down in 2004 and gave GM another try and bought the great Dmax everyone brags about. It was a SRW 3500 4x4 and I got it 2 months after buying a 2004 F-250 with the dreaded 6.0L Powerstroke. The Ford I still own with zero problems. It has not been in the shop 1 time. It has been great even though I chipped it, changed the intake, and basically run the heck out of it. The Dmax on the other hand was plagued with electrical problems form day one. It also had paint peeling that was resprayed by the dealer but the big problem was the Glow Plugs and Injectors. This truck lasted me only 9 months and I traded it for another Ford 6.0L Powerstroke that I still have. It is the truck that had the bad dash cluster. It was frustrating but the dealer took great care of me and loaned me a new dually while my truck was in the shop for 4 days.
It all comes down to luck I guess. I have had bad luck with GM products and especially the dealers while I have had good luck with other makes. I did own one Dodge for 2 years and it had its share of problems but they fixed it even out of warranty and always gave me a loaner better than what I had. I really like the dealer but just could not trust the Dodge. I was afraid to take a 1 year old $35,000 vehicle more than 50 miles from home.
