1998 Suburban almost wrecked several times to do faulty electronic variable orifice (evo) sensor located under steering column. When in a right hand turn vehicle will suddenly lunge to the right to do sudden increase in power steering. This is very dangerous and GM or anyone for that matter is doing anything about it. I think it should be a recall immediately. There are plenty of documented cases of this problem and GM knows it too... but they refuse to fix the problem.

When driving at almost any speed steering slips and jerks to right or left. The tires don't move with the slip. It started out as just a right shift, and now it is jerking both to the right and left.

Vehicle was delivered to me with a noticeable pull to the right. Repeated trips back to the dealer for service and repeated talks with various levels of management at the dealership have not corrected the problem. In fact, the service personnel refuse to acknowledge the problem at all. An independent repair shop has also been unable to correct the problem. I have given up on trying to get the problem fixed, but still consider it to be a serious safety issue.

Vehicle veers to left / right, counter clockwise from the way its swings. This happens at 55 to 60 mph. Dealer has been contacted. Vehicle has had continued component replacements in the suspension and steering due to defect. Also power steering sensor was replaced/nuts:bolts that hold tire together sheared off, causing tire to fall off.

Power steering pump also powers the braking system. Brakes fail at panic stops and pedals go to floor. Power steering system causes the vehicle to wander at hwy speeds. Requires constant readjustments. At times will lose control. GM says normal. Have contacted them and refused assitance in these issues but received only standard corporate no assistance/form answers.
