I have a 2010 V6 Equinox that doesn't maintain it's speed when climbing a grade in cruise control. If the vehicle is set for 100 kph the unit will often slow down to say 94 kph then speed up to more than 100kpm at the top of the grade. It seems like the vehicle stays in too high a gear when it starts any assent loosing speed then it downshifts several gears to catch up but overcompensates at the top of the hill. If I place the vehicle in manual and downshift accordingly, the vehicle doesn't slow down noticibly. BTW - The vehicle has good power on the highway and as a whole.
My question, can the V6 models be equiped with a more aggressive shift pattern for hilly areas? The 4 cyls have an ECO mode that delays the shifts. Why can't GM include a sport mode for the more powerful models. Give the driver the option. I have had too many people climb up on my bumper while climbing a hill because of the sudden drop in speed. My dealership has informed me that there is no firmware upgrade for the V6 models. Don't the Caddys have the ability to modify their shift pattern to be more aggressive?
