We purchased a 2018 Colorado. After a few weeks my husband noticed that the rear of the truck bed was notably an inch lower on the Drivers side than on the passengers side. They refused to fix the problem. Initially when I tried calling the Service Department I was transferred to a Full Mail Box. I finally had to call the Sales Department to get anyone to answer their numbers. Think Twice then think again before using these guys. BTW Bernard in their Service Department was great. Their Service Manager is more dull than wheat toast.
