It appears the 1981-1991 Suburbans are pretty reliable. I have a friend that used to have a 1989, and now owns a 1997 or 1998. He's had multiple problems costing thousands of dollars to repair. I thought perhaps he just had bad luck. Today I searched on MSN, and lots of people have reported just terrible luck. Transmissions, electrical bits, fuel pumps, electronic door locks etc. While on the other hand, looking at older reviews, mostly people just complain about gas mileage. What's your experience, I'd like to hear it. The 2000-2006 trucks have hardly any complaints, but I figure that is because they are so new.
