Twice now I have problems with the vehicle shuddering while trying to keep a constant speed above 50mph. I believe GM has a problem with the 2017 Colorados; not Lafferty's fault. Lafferty is always in the know and has excellent service with caring service advisors.
Dan--Good to hear from you. I will review this on to my service staff and see what can be done.--Have a great day.--Jack Lafferty
