On October 27, coming back from a family trip at 10 PM at night on a major highway, the suburban all of a sudden quit. Traveling at 70 miles per hour, all of a sudden, when pressing the gas pedal, the car would not accelerate and the RPM gauge was erratically moving. The car started to slow down till it eventually just quit and it would not go anymore. We were stranded in the middle of the highway with cars coming and going both ways. It was scary, it was dark, and dangerous. A tow truck was called and they told the suburban to a Chevrolet dealership 60 miles away. The following day, the dealership informed us that the transmission was not repairable and that they had found metal pieces in the transmission. They informed us that the only way to repair was to replace with a new transmission. They informed us that these transmissions are faulty and that it-??s common for them to replace transmissions in suburbans about twice a month. We were not happy to find this out because this is the second transmission in a second Suburban that we have owned that we have had to spend $12,000 on between both vehicles. The car was out of warranty, Therefore, the expense was totally on us. I need help trying to see if I can get reimbursed for these expensive faulty transmissions that are not our fault! We have serviced car when due. There were 4 small children in the car and we could-??ve had a tragic accident because car quit suddenly! Please help!

When adaptive cruise is engaged, the system hesitates when lead vehicles slows at a slow rate (no brake lights observed on lead vehicle), requiring operator to apply brakes. When adaptive cruise control is engaged during highway driving, intermittently, medium slowing of lead vehicle (brakes applied) the vehicle does not react in time to avoid collision without active and heavy brake application (jerking driver and/or passenger) to avoid collision. Above 65 miles an hour the adaptive cruise control does not leave adequate distance between vehicle and lead vehicle. I first noticed this immediately upon first long distance drive. This is an ongoing problem. Happening frequently between July 4th and July 12. Since the July 12 the car has not been used frequently in situation where the cruise is used regularly. However during the few times on the highway between July 12 and now, the problem has reoccurred.
