While driving at 55 mph on dry concrete limited access highway on interstate I-820 southbound, approaching I-30 westbound at interstate interchange, slowed to 50 mph as turning to right at approximately 30-45 degrees of steering wheel input were applied to start right sweeping turn from tangent direction. ) as desired steering angle was reached, steering angle was unintentionally increased by the power steering system. Vehicle turn rate to the right exceeded the necessary amount and vehicle initiated a turn-in oversteer. Steering angle was reduced, but when re-initiated, the turn-in oversteer recurred. This situation continued to plague this vehicle, today. No repairs have been attempted, since the dealership won't agree that anything is wrong.

The variable effort steering on my 1999 Chevrolet Suburban C1500 is failing to attenuate during almost all turns from tangent. I get almost full power assist at road speeds from 45 to 70 mph; this can be quite unnerving even at slight steering wheel inputs. Usually there is a "break point" at which the attenuation is normal up to that point, but beyond the break point, the wheel becomes quite "light". when this occurs, the steering input torque at the wheel is decidedly "too much" and more steering than necessary enuses. On dry pavement, I have actually heard the rear tires sliding during interstate interchange driving. On wet pavement, even with new tires and proper inflation, this is getting quite scary.

When turning there was no resistance. When the consumer made a sharp turn, the steering later became very soft. The consumer contacted the manufacturer who was not engaging in the defect of the steering column. Provide further details.

While driving slowly or fast, at different times, and not every single time, turning to the right around a curve or turning a corner the steering holds the turn and then all of a sudden lets go of that hold. I can correct it by slightly turning the steering wheel left and then back into the turn. Sometimes it holds the second time and sometimes it lets go again. This is repeated until the end of the curve or turn. Steering gear, pitman arm, steering pump all replaced and problem still is present.

Sub died on the road. Alternator replaced 3 times in 60K miles. Steering jerks while turning over correcting could cause crash. Front disc brakes replaced annually. Replaced front left caliper and rotor. Too many problems with this peice of junk bought new. Local dealers no help. Just milk me for more money. Now transmission is leaking at 67,000.

Finally at the end of this form I get to describe the problem. The NHTSA, however, has already received several othercomplaints on this matter and opened an investigation and completed it. I simply wanted to find out the results of the investigation that was conducted. The problem concerns the severe erratic steering on my 1999 Chevy Suburban. These vehicles are dangerous and I hope something was done to draw attention and solve the problem.. I have the same problem as the many other consumers had that complained. How do I find out what to do or how to repair the problem"?"no safety defect listed.

Erratic steering - vehicle wanders in lane and has no tactile feedback to tell you that you moving left or right. Steering sensor has been replaced once and has been tested several times. Problem is very intermittent. On last occurence simply stopping the vehicle and shutting off the engine and restarting it returned the steering to normal. No one seems to have a solution for this problem.

Erratic steering behavior. Vehicle wanders excessively on the highway and will unexpectedly pull or veer to the right side of the road. When this occurs, considerable corrective steering effort is required to resume and maintain a straight course. Dealer has been contacted twice regarding this problem.
