2000 GMC Jimmy Diamond Edition 4.3 V6 Vortec from North America
Summary:
Beautiful truck, but costly repairs
Faults:
Radiator replaced (may have been mechanics fault)
Intake manifold gasket at 110,000 (thanks to the first appearance of Dexcool)
Transfer case started having problems 2 days before trading it in.
Shocks were on their way out.
Balljoints constantly go, though I never got the chance to replace any; I sold the truck before they would go.
General Comments:
Engine is good, only problems are Dexcool related (whole cooling system will go on you; heater core, heater cooler lines, radiator)
The original Dexcool would eat the gaskets and so on, causing the above problems.
Truck too heavy for its frame, causing suspension problems (ball joints, shocks).
Beautiful looking truck, but could no longer afford $600 repairs per visit to the mechanic.
Would you buy another car from this manufacturer? Yes

Although I don't own a 'Diamond Edition' or a Jimmy for that matter, I do have a very similar Sonoma SLS regular cab. The truck did good at times, but when things failed were generally expensive. Only months after purchasing the truck, the timing belt broke costing $669 to fix and not six months afterwards the alternator failed. This was all in 2004. No major repairs for 2005 but in 2006, the master brake cylinder failed, repaired then brakes failed again.
The truck became a money pit and I decided not to follow anymore the maintenance schedule and at last she died in August. I will repair and sell this pit and be glad she is out of my life.
