2002 Chevrolet Tahoe LS 4WD 4dr SUV (4.8L 8cyl 4A)
The transmission went out initially at 75k miles, then again with 97k miles on it (luckily under the 36k warranty). Now with 106k miles on it the flex fuel sensor has gone out, and guess what? It is a dealer only part (quote for $800.00 from dealer to fix) You can buy on-line from GM for about $300.00 vs $500.00 at the dealer (love the markup) All in all I will never own anything from Government Motors again, worst reliability of any vehicle I have ever owned. Which is saying something as I have owned an old IH Scout which lasted longer and caused me less head aches.
Seats are more comfortable then the expedition I now own.
Figure out how to build a transmission that doesn't blow up ever 30k miles.
