Driving anywhere over 1 hour is a gamble. This has been to multiple Suzuki dealers and they do as you would expect. Throw money at it, until it fixes the problem.

Typically driving on the highway around 70 mph for an extended period of time (40mins +) causes what I believe the transmission to lose power. The RPM's rev up anywhere from 2k-5k,and its similar to symptoms of a slipping clutch. A check engine light comes on, and each mechanic cleared it after reading it and still no solution. The car will be sluggish and struggle to go uphill at anything but level. It's dangerous and not as common from what I am researching.
