Biggest waste of money
Brian, 11/26/2024
2025 GMC Sierra 1500 Elevation 4dr Crew Cab 5.8 ft. SB (2.7L 4cyl Turbo 8A)
I bought a brand new 2025 GMC Serria Elevation Premium. I've had it exactly 1 month today. It didn't even have 65 kilometers on it when the engine light came on. It has spent a total of 2 weeks at the dealership and they still can't find out what is wrong with it. How can you build such a piece of garbage and not know how to fix it. The dealership told me it's not their problem however, … it is actually their problem because they are the ones selling these pieces of garbage. I will never buy another chevy or gmc again. If I would give a minus 5 star review if it would let me.
