While entering I-880 @ 45 MPH increased speed to 60 MPH to get into the flow of traffic. Car accelerated to 70-80 MPH. Attempts to slow the car down by stepping on brake did not work but the car continued to accelerate to 80-85 MPH. I had to switch lanes to not hit car in front. All attempts to brake did not slow the car down. Stepping on the gas peddle numerous times finally allowed the car to slow down. Initially believing car was in cruise control I did nothing. This happen 3 more times when I would accelerate to pass a car on the freeway and once on a private road. The latter was done intentionally, late at night, to assure my mind it was really happening. Car is in the dealer now and they are telling me nothing is wrong with it. This needs to be documented since this appears to be a very serious safety concern when a driver has no control of the vehicle and given the circumstances a lot of lives seem to be at risk including my own. This seems to be the only place to file this information since dealer stated that consumer complaint cannot be filed since saturn no longer makes vehicles. As I stated to dealer saturn is covered under gmc.

When car is in cruise control it is constantly downshifting to maintain speed even on flat surface. Apparently the gearing on the transmission does not support to weight of the vehicle and it cannot maintain the cruise control speed. The service department said there is nothing they can do.

The car is a 2008 saturn vue 4 cylinder automatic with two main safety problems. Problem one is the car will lock you out automatically with the keys in the ignition. Car can be running or shut off. This happened twice with my son in the car. This has happened about 14 times. Luckily I had the windows rolled down and was able to access the car. Saturn has repeated this problem on other vue and deems it a "normal function" even though the owners manuals says there is a function in the car engineered into it to prevent you from locking your keys in the car accidentally. Again this happens automatically a minute or two after exiting the car. Problem two, transmission abruptly downshifts and accelerates on flat ground or slight grades while in cruise control. This also happens sometimes when cruise controls is disengaged as well. My wife almost lost control of the vehicle one due to this on a curving road going up hill. I almost hit a vehicle when this happened as well. Multiple dates of these problems happening. This is an intermittent problem and happens between 40 and 60 MPH. The vehicle has been in the shop 47 days since it has been purchased.
