What owners wrote

Brand new vehicle purchased from dealer, at 8900 miles transmission slipped. Dealer has for 2 hours and couldn’t find problem, but replaced transmission fluid it was dark. At 9000 it happened again, they have vehicle and said the new transmission fluid is dark and muddy. Only 100 miles, so they determined they need to take apart transmission and see what happened. It’s a 52k car, it should not be repairs, it should be replaced under warranty. Video of 8900 from dealership [link removed]
