2024 GMC Sierra 1500 Pro 4dr Double Cab 4WD SB (2.7L 4cyl Turbo 8A)
Bought a new Sierra 1500 Denali…
Bought a new Sierra 1500 Denali Ultimate just over a year ago. 3200 miles into it engine went. In the shop for a month. It went back into the shop approximately 6 months later fo two recalls and needs to go back and in for some odd behavior with the transmission. Funny sound and showed it was in ‘off-road’ mode no matter what I did. That has now gone away … but who knows?
A little of my history before I continue, my father retired from GM Manufacturing, my stepfather, mother and most of my family worked for GM for many years in and around Saginaw, MI. So we have always been GM people.
Bottom line, never again. Not only did GMC not buy back this lemon, they really refused to do anything other than do the repairs.
Looks great, great bells and whistles, nice to interior. Piece of crap that the company will not acknowledge.
I will be a Ford buyer from here on out, even though I can buy GM through the family plan.
Thoroughly disappointed in what has become of this once great company.
All I can say is if you still choose to buy one of these vehicles, know your on your own.
Gene
PS: ignore trim details below. Did not have mine but will not let me change.
