general problems of the 1997 Chevrolet Tahoe

Power steering input/effort had became erratic causing increased effort or worse, oversteering midway through turns. First noticed this problem last fall at winter tire changeover. I initially blamed it on icy roads but then noticed it on obviously non icy roads as well. Occurred just occasionally at first. I kept blaming tires but this spring when I changed back over to my summer tires the problem did not go away. Dealership had indicated some worn front end parts needing replacement so I had that done along with a front end alignment following. Didn't help. Found many discussions with similar experiences on the internet and most indicated replacing the steering evo sensor as the cure. I replaced that part and it seems to have fixed the problem. The sensation of the loss of steering midcorner is at the least a little disconcerting and at the most could lead to an over-reaction and a severe crash! with as many complaints online as I found I don't understand how this could have been let go and not called to my attention by the company. The company knows about this problem as the parts clerk told me they even have a retro kit available to replace this assisted steering system period!.

Noticed erratic steering during right turn. Became more severe over time, to the point it was difficult to maintain control of vehicle. Had vehicle inspected by local mechanic. Failed evo (electronic variable orifice) sensor in steering was replaced.

While driving vehicle steering wheel suddenly slips or jerks to the right. This problem is intermittent, but has increased over time. On January 28, 2003 the vehicle was taken in for this problem, and the dealership replaced the steering sensor. The problem has recurred 22 months later, causing driver to lose control of the vehicle at 35 mph. This resulted in lose of control of this vehicle and accident followed. Chevrolet customer care service was contacted and said that they would pay for inspection of said vehicle. They responded that if no problem was detected during inpsection, that customer would have to pay for repair. Inspection is still pending.

While turning the steering wheel, the consumer noticed that the steering wheel jumped. The technician serviced the vehicle and a replaced the sensor. This problem occurred many times over the past three years and would fail while turning at low, medium and high speeds.

The steering in my 1997 chevy Tahoe has recently started to "jerk" while I am driving.

1997 Chevrolet Tahoe steering at 83,000 miles. At 45-55 mph when turning left steering has a momentarily twitch/hang-up/resistance/jerk. After many attempts I finally found a dealership to diagnose that the steering wheel position sensor was failing & needed replacing. After searching the NHTSA I see several complaints of the same problem. It is hard to believe with a serious problem that impacts steering ability for Chevrolet Tahoe owners & others driving safety that there has not been a recall. Hopefully something is done before there are injuries/accidents/fatalities.

Steering wheel jerks to left or right on cold days when driving at moderate to high speeds. After reading the number of complaints for same exact problem it appears the gvt is waiting for a fatality before taking action. Nhtsa action number ea 99011 was closed 02/27/2001 with no action taken.

Steering briefly and suddenly goes "light" in sweeping right turns at 40+ mph. Feels like you hit a patch of ice. Sounds related to other complaints on your site I found while researching possible causes. Have not taken to dealer yet - appointment next week.

1997 Chevrolet Tahoe steering problem in curves. Very dangerous. When making a turn in a curve or a lane change you experience a temporary loss of steering followed by a release causing a oversteer condition a very hazzardous situation.

Steering is erratic at medium speeds. You will be going around the corner and then the wheel will give and the truck pulls very quickly, as if you oversteered, but then it will stop.

Erratic steering.

Consumer states that while driving and no warning they will have erratic steering control and it will be hard for the consumer to control the vehicle. Dealer notified ts.

Vehicle is very difficult to steer, it wanders all over the road, dealer replaced tires, serpentine belt and tensioner and performed front end alignment, this did not remedy problem.

When turning left or right steering wheel will jerk in that direction and cause vehicle to turn more than intended, like someone is jerking it out of consumer's hand. Consumer stated this wa svery dangerous. Dealer said it was a sensor that needed to be reeplaced. Please provide any further information.

Steering loses resistance, changes lanes if not counter steered. Dealer replaced evo sensor on 9 April 2002.

When negotiating curves (while driver is turning steering wheel and holding fairly consistant pressure on the wheel to maintain the turn), the steering wheel will suddenly turn (twitch) in the direction you are turning. This sometimes causes an oversteer to correct . Problem is worse when veh. Is cold and does it mostly around 35 mph although regularly does it at all speeds also. My sense of the problem is not that the vehicle is "steering itself" , but that there is a sudden change in boost to the steering (defective speed sensitive pwr steering?) and since the driver is holding pressure on the wheel in a curve, the sudden change in steering boost causes the driver to oversteer and than overcorrection in steering, which to some complainants apparently is perceived as a loss of steering. My wife perceives it as a loss of steering and I drive the veh as much as her and can tell you the loss of steering is in the mind due to "pucker factor"! I can tell you without a doubt that the problem is very real and I have had 1 or 2 near misses with a car and jersey barricade as I oversteered with the sudden change of boost. What you need to understand is that the sudden change in boost probably occurs regularly at the appropriate speed, ( as designed into the speed sensitive steering system), but when the driver has turning pressure on the steering wheel, and the normal steering wheel back-pressure is suddenly released (or signifigantly reduced)the 1st action is a sudden oversteer (as though someone quickly jerked the wheel loose from your hands in the same direction you are already turning). I see many similiar complaints in the complaints database and a NHTSA action # ea99011 open investigation since may 12, 1999, seems that this is a definite widespread problem. Is there a fix on the horizon? I see that some dealers have replaced the steering speed sensor, but it is not clear if that is the cure. Any suggestions?.

While making turns steering sensor goes out intermittently, and steering becomes very loose, no resistance. Consumer checked our complaints database, and on January 3 found 40 complaints with same problem.

Power steering over-assist, bad evo sensor.

Consumer was traveling 55mph on the highway went to make a slight turn, and the steering wheel was fighting with him. After turning the ignition off at a rest area, the problem went away for awhile. After it reoccured, owner had faulty evo sensor replaced, no problems since.

While driving and attempting to make a turn, the vehicle over turned, causing loss of control. Driver has had to drive off the road.

Vehicle steering loses control. I have complained about this several times to the dealer while it was in warranty and nothing was done about it. I see that others had the same problem. I told the dealer this is a serious safety issue that could cause serious injuries and even fatalities. Note: I took it to the dealer and this is what they said vehicle experienced a TSB (76-30-01) failure of the electronic variable orifice (evo) system as a result of low voltage condition of the steering wheel position sensor, which resulted in accident due to loss of control.

The play in the steering increases and becomes loose with high speeds. The ves system is working the opposite of what it is suppose to do. Truck will be checked by the dealership on Jan. 25-1999. . Et.

While driving there is tension on the wheel . When slowing down to to turn, the tension loosens and jerks to the left. The dealer has ordered the parts to repair vehicle.

Ea99011, due to a defective steering speed sensor, steering system malfunctioned, causing erratic steering while driving in high speeds. This could result in a crash. Dealer was aware of problem, and would extend the warranty only if the he could duplicate the problem. Common problem. Please provide further information.

Ea99011, while driving on the left lane, the vehicle moved to the right lane unexpectedly which could have caused a crash. Incidents happened twice. Please provide further information.

Power steering sensor has been replaced twice at 34000 miles and again at 60000 miles. When making a turn steering wheel will jerk away from turn.

The vehicle's power steering is over sensitive and will react to the slightest movement of the steering wheel. Dealer says it needed a new steering box. Problem still exist. The steering sensor has been replaced to correct problem.

When making a left hand turn,and then straightening vehicle out, steering will push to the right.

Over steering occured because of sensor failure. Yh.

Ea99011, intermittently while driving, steering system malfunctioned, causing vehicle to wander which could result in a crash. Dealer could not determine cause.
