Good letter Beebs...
With regards to tires, mods etc - mine is standard base model running 32" tires and my front diff went on me around 3mths ago - my car was in the dealer for 4 WEEKS as no parts in the Middle East and according to Service Manager - GM U.S.A had none in stock either... WTF?
As a result of the dealer trying to use the original casing - the car has now been in the dealer for 3 weeks, and I don't expect to get it back for another 2-3 weeks while they wait for a complete new diff assembly including the casing.
So... apart from the fact the diff's are a known problem, it's obviously considered okay for a customer to be without a car purchased new from the company for over 2 MONTHS due entirely to the front diff?
Yeah, my dealer screwed up, but if the diff was good in the first place it wouldn't have happened.
I really do hope someone in GM takes notice... otherwise, they'll lose sales for those that are gonna buy a car for use off-road and do a bit of research first!!
Cheers
