I bought a 2017 Chevrolet silverado 1500 back in November. In late January i opened a case with GM regarding vibration issues. After 1.5 months and 3 visits and changing 2 tires they informed me the vibration was normal. I have been threatening them with a lawyer. Then last week i recieved a letter from GM. The letter stated that an error had been made on my truck window sticker. At the time of purchase my window sticker said the truck was 35% mexican parts, 48% Canadian parts, and the engine was made in the U.S. The new label informs me that my truck is really 56% mexican, 38% Canadian, and the engine was made in Mexico. GM has informed me that i can not sell my truck with the label i purchased it under, which is exactly what they did when they sold me the truck.
