One problem related to vehicle shudder has been reported for the 2007 Chevrolet Suburban. The most recently reported issues are listed below.
Transmission stopped working while driving had been slight vibration several month prior which was reported to dealer-he said wheel balance-did not help only 1st and 2nd gear worked. Local dealer quoted $2,800 to replace. Dealer had the car for over a month. Gm offered to pay 45%. I would pay $1540. When picked up car I had to pay $2300! told the warranty from gm caused the price to go up. The car still has a vibration. A car with 80,000 miles should not need a new transmission.
