EA99011-erratic power steering assist. While driiving vehicle goes down a straight road, hits a slight bump, causing the tension in the steering column to release, which results in loss of control. However, the same problem is more intensified when going around curves. Within the past month, the vehicle has been at the dealership 3 times for this problem. The steering sensor / steering box have been replaced. Consumer is still experiencing similar problems.

I experience a very noticable twitching in the steering in a turn at high speeds greater than 50 mph while towing a small trailer. This is noticable only when the vehicle has downshifted into 2nd going up a steep grade.

The steering problem felt like I was driving on ice. It seems to slide for a second and then the steering comes back. The problem happened last week and I just had the truck back to a Chevy dealership to change the sensor as warranty work. I got the truck back yesterday and did not notice the sliding action any more, but it has been just one day. I'm sending this complaint because I heard about the investigation and wanted to submit my information.

My steering has locked on me while driving, my car would not start due to crack in the battery and acid leak, my car had to be towed to repair shop due to starter cable popping off. Currently, I am stranded due to my brakes losing power somehow.

The variable effort steering intermittently and very sporadically goes from normal steering effort to almost zero steering effort causing an oversteer and near loss of control situation. This usually occurs (but not always and not the only situation) during a long continued turn such as found on entrance and exit ramps of a freeway or highway. Sometimes the opposite problem occurs where instead of an oversteer situation, it is difficult to get back out of a turn. This is a tremendous safety problem especially at highway speeds where a normal lane change can suddenly turn into a S-turn. This is difficult to duplicate on a test drive since it is sporadic and comes suddenly without notice.
