 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! *tr
 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.*ak
 While turning the steering wheel, the consumer noticed that the steering wheel jumped. the technician serviced the vehicle and a replaced the sensor. *ak this problem occurred many times over the past three years and would fail while turning at low, medium and high speeds. *sc *jb

 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. *jb
 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. *jb
 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. *ak
 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 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. *la
 Erratic steering. *ak
 1997 chevy tahoe - after making a u-turn, power steering failed. in addition, while driving curved roads, an abrupt jerking would occur in the steering. *jb
 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. *jb
 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
 Steering loses resistance, changes lanes if not counter steered. dealer replaced evo sensor on 9 april 2002.*ak *tt
 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. *ak *tt
 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.*ak
 Steering position sensor failed, causing the power steering system to lose resistance at speed. incident occurred while driving on a sweeping left hand turn. i was applying constant light left hand pressure on the steering wheel when the power steering system lost resistance and the wheel turned freely and quickly to the left. before i regained control i had moved 1/2 lane to the left. the problem was very intermittent at first but grew increasingly more regular. the steering would seem to twitch and cause momentary loss of feel. i*ak finally replaced the steering position sensor and the problem was fixed. when i purchased the replacement part at the chevrolet dealership, the parts counterman new exactly what i was talking about and commented that it must be a big problem because they had a whole bin of steering position sensors. it is my contention that this should be a recall item. the sudden loss of steering control can be very un-nerving.
 Steering was like on ice, had to replace steering sensor, front disc rotors warped twice, had to replace. *ak
 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?*ak

 Steering on my 97 tahoe has for many years 'twitched' when driving at a slow right turn such as on ramp to freeway or slow curve in the road. it never does it on left turns, only right. the steering wheel suddenly pops to the right and only for a second. it then repeats that if the turn on the road is continually to the right. if anyone other than me drives the tahoe, it will surprise them and cause and accident. ive read about this problem in many forums online as well as here at the nhtsa site. gm should be recalling this dangerous steering problem immediately.
 The steering assist on the tahoe suddenly goes away and the steering goes completly loose, and then suddenly it gets firm again. this causes erratic steering and over/under adjustment which can lead to a serious crash. i took it in 2 times and the problem still comes and goes, esspecially while in a turn. this should be a recall because of the seriousness of the problem. if the pwer steering fails it should fail to a firm steering condition not a total loss of steering!!*ak
 When turning wheel either left or right, a momentary loss of control causes the vehicle to oversteer. feels like the steering wheel has become disconnected or the power steering has surged.
 This is to confirm that ea99011 concerning the steering on the 1997 tahoe, 350 5.7 assembled in mexico. the jurking in the steering is not a constant problem. i t does not happen all the time. however, there have been instances where the vehicle was travelling at high speed and this uncommanded imput was enough to induce the vehicle to lurch to the next lane.this sever action only happened once, however as the vehicle ages, the severity seems to get worse when it does happen. yje vehicle has done this since i purchased it new in 1997. i also have confirmed this same thing with a friend who owned a 1997 saburban, he sold the vehicle as a result of this condition.
 Loss of steering control in cold weather conditions on snow and ice covered roads on my 1997 chevrolet tahoe. the variable assist steeriing would make a rapid and unexpected over adjustment when making small steering corrections. i lost control and started a fish tail when traveling in new york. i live in virginia and found this to be a minor problem in this climate, however, it is unsafe on slippery roads.
 When making a slight right 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. i contacted the dealer and asked about a recall on this. the person in the service department said it was only a problem with the 1997 models. this problem needs to be checked out before someone gets killed. please contact me with reply ts

 Both times the steering sensor failed was at highway speeds. the first time i was switching lanes and all of a sudden it over corrected and almost sent me into the ditch at 65 mph. the second time my wife was traveling on the interstate at 65 mph and turned the wheel a little and it sent her into the next lane cutting off another vehicle. the first time i had it fixed the guy said oh yeah we have been having problems with these. the next time i had it fixed i figured they would just replace it since they know there is a problem with them, but they charged my $150 parts and labor. i am going to contact the manufacturer next. it was very dangerous and i cannot believe something like this isn't being corrected.

 The steering occasional appears to be very light, like it was floating in the air. and the steering appears to over compensate during the steering pulls by itself. dealer replaced the idler arm , and did front wheel alignment but the problem did not go away
 Steering erratic at all speeds when turning or changing lanes, feels like lose control of steering. this was reported several times to jack wilson chevrolet in st augustine fl, who told me there was no problem.i
 While driving along a road at about 25 mph my power steering failed and never returned. the dealer indicated that a sensor became loose and caused the power steering pump to fail. they suggested that i call the gm hot line. gm was not very nice or helpful. they asked how much mileage. they indicated that anything that they would do would be under their good will program. they then asked me how much i was willing to pay. when i indicated gm=80% and me 20% of a $462 repair bill they asked me to hold on and then came back and said that they were not willing to pay anything. i asked them why they even bothered to ask me how much i would be willing to pay--and they indicated that the truck had a lot of mileage and that i should have taken the extended waranty program. i feel the dealer was trying to inform me that this power steering pump should not have gone in the mileage that i had. i believe that a bad accident could have resulted had i been driving on a curvey road. gm appears to be disinterested in my welfare. i thought that beonka jones was very rude in handling the matter.

 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.
 Idler arm failed. *yc
 Windshield wipers work occasionally on high, but most of the time not when it is e fuel pump has had to be replaced two times and does not give a warning that it is going to to quit. the steering has a bad place in it a approx. 50mph going around a curve and will pull harder in to the curve, either there something wrong with parts to this truck or i have a lemon. i have spoke with others and their wipes do the same thing.*ak
