Cruise Control problems of the 2002 Suzuki Grand Vitara

My 2002 Suzuki Grand Vitara (limited 4wd) was involved in a single car accident when the cruise control was engaged on the highway at 55 mph. It was a hilly stretch of highway near pittsville, mo and there was a light dusting of snow just starting to fall. The cruise control made the car jump into a lower gear when ascending a hill to keep it at 55 mph. The rpm's jumped from about 2,000 to 5,000 when the car shifted into 3rd gear - which caused the tires to lose traction and I wrecked into 2 highway sign posts and skidded sideways about 50 yards into the center median. It was a miracle that I didn't roll over several times. It cost me $5,000 in collision damage to fix the car. The cruise control does this all the time still when even on moderate hills to keep up with the set mph. It is a design flaw in my opinion. I have never had a car that needed to jump up to over 5,000 rpm's just to go 65 mph and stay up with the set cruise speed. Thanks. Dws.

While driving at 35 mph on busy streetvehicle experienced sudden acceleration. Consumer stated her four year old son was in the vehicle, and could have been killed.
