| My 2003 chevy silverado goes into gear with out pressing on the brake, also the truck will go into gear with out the keys in the igintion. the e-brake is also defective, the e-brake does not hold the truck. my 2 yrs old son was sitting in the truck on 9/20/2011 when the truck went into gear. i live on a incline my truck rolled down the hill while i was chasing the truck truck on foot, the truck finally came to a stop when it hit a 98 toyota tacoma which was parked in the drive way accross the street. the e-brake was set , the keys were not in the truck, the truck was not running! my son could have killed himself or someone else due to the fact the truck is not safe! | |||

| 1. poor ride, vibration, while driving at various speeds. mostly between 35 to 50 mph. had the problem with stock tires. replaced with after market tires, slightly larger. still had annoying vibration. to a point that i do not like to drive the vehicle! 2. fuel economy sucks! i upgraded from my '92 gmc pickup which gave me 12 to 14 mpg around town to 15 to 18 mpg on a trip; to my new chev. which is good for about 9.5 to 9.8 mpg around town and the best ever, on a trip was 13.4 mpg!!! 3. the bench-type seat is not adjustable to remove the vee feeling when driving. 4. the self-darkening mirrors are a hazard when trying to backup or change lanes! 5. the passenger front seatbelt locksup and can't be freed unless you unbuckle and reattach the belt, only to have it lockup again! i have had the vehicle back to two different dealers on three seperate occasions principally for the mileage and the very annoying vibration! i have contacted general motors, also with no success! i've changed tires, asked to have the transmission checked for the vibration, only to have seperate service managers tell me that it seems okay to me, and that there's nothing on the computer to indicate a problem! and you put bigger tires on the truck! you can't do that! i just celebrated (?!!!) my first anniversary with the truck and its been a miserable year!*ak | |||

| Constant wind noise from hood hinge flaps and top windshield seal at 50 and above. also driver door seal squeals. i repaired the flapping noises myself after the dealer tried 6 times and said it was my bug deflector. the door seal was replaced after 6 trips and is worse now than then. i repaired this as well as i could. they replaced 1 of 3 seals. after 6 visits for my goodyear tires (nothing found wrong again) they decide to replace them. it took 2 weeks to get tires and then they replaced 2. the trans is clunker and has computer software issues causing shifting problems and dealer can not duplicate. the computer thinks it is ok so no codes will be stored. i also pointed out the gm tsb's to them on this problem. i may as well go to the zoo for service at least i get to expect poor service from wild animals. i wrote the vp of gm and he responded to me and forwarded my letter to vp of sales and service. went back for repairs and still have same problems and the new tires with 1000 miles are bad just like the others. $38,000 piece of junk with $3.00 hr monkeys repairing it. what a joke, they can have this truck back since there is nothing wrong with it. i was also refused service two times by my local dealer because i bought it else where. service manager said: "you are not our loyal customer and if we decide to service you, you go behind our loyal customers, reguardless of order". i think he may be looking for other employment now that the vp called me to discuss my concerns, but that is still against the law and the gm contract. think i am going to just get a horse and when it stops working just shoot it. | |||

| Vehicle seems to go into 4-wheel drive by itself while driving . this has happened to me three times already. i want to switch dealers but gm told me no i have to stay with the dealer who worked on the vehicle. as this happens the vehicle slows down considerably causing the seat belt to lock and hold me back. also at times the vehicle just slows down while at highway speeds. the check 4 wheel drive light comes on and the push buttons on the panel do not operate. (the lights go out) i also think this has caused my odometer to fast forward. it tells me now that i have 29900 miles on the truck . i have all records and need help. i travel to work 8 times a month and round trip is 114 miles this does not seem to work out . can they check the electronics and see actual miles from the computer. *jb | |||

| We all need to contact gm at www.chevrolet.com and complain. i purchased my 2003 chevy 2500 hd in nov. 2005. it had 32000 miles on it. the warranty ran out at 36000 and when i hit 38000 miles the problems started. the electrical system started acting up. i had went to leave and everything was dead no power at all. i would jump it and then it was fine for the first couple of times. the last time i jumped it, it cranked but i had no power it wouldn't move in drive or reverse and all the gauges went crazy. i disconnected the battery waited a minute and reconnected it and everything was working fine again. a week later the speed odometer went crazy and wouldn't go back to zero. now starting a few weeks ago the drive train is making a loud clanking noise and the rear wheels are wanting to lock up when i try to start off. these problems don't occur every time, but the drive train noise is getting worse from all the feedback i see on this web site i feel i would waste my time contacting gm. all of us chevy owners with problems needs to contact gm every day about our $30,000 and $40,000 dollar hunk of scrap metal. i hope mine will burn and i will not ever buy another chevrolet product again. here is there web site www.chevrolet.com. i have been calling the phone # on the web site, but it just stops ringing. you can send them e-mails and letters. *jb | |||

| Frequently my 2003 chevy silverado hesitates to pull off after coming to a complete stop. i've taken it to two dealerships for the problem with the transmission. they state it is a problem with the computer programming which has the transmission pulling off in second gear instead of first and they have no solution for this problem, just keep driving. *jb | |||

| Dt*: the contact stated while driving 10 mph and below, the steering allowed too much play and maneuvered loosely. the vehicle was taken to the dealer who replaced the steering shaft. however, the problem still exists. the rack and pinion had a slight leak. the consumer has had numerous components replaced on the vehicle such as wheel bearings, ball joints, tie rod ends, control arms, steering gear, shocks, steering linkages, coils springs, wheel hubs steering column and the power steering gear. the intermediate shaft was replaced three times and lubricated the last time. the consumer was told the steering design was flawed, which contains a looseness that can't seem to be corrected. the transmission hesitated at times. the dealer stated the clutches were burnt and glazed. the tires were exhibiting premature wear. updated 08/02/06. *jb updated 04/16/08 | |||

| Dt: the consumer complained about several problems. while driving he had trouble shifting from first gear. the dealer reprogrammed the engine control module and the transmission module control. the vehicle was still shifting hard, and the rpms revved. the replacement of the aforementioned did not remedy the transmission problem. the second problem was with the brake light coming on the cluster assembly. the service dealer replaced it, and it seemed to work well at this time. the third problem was with a noise in the rear of the vehicle. the dealer replaced the gear kit, two gaskets, case, the rear differential carrier assembly, carrier gears, and shims. the noise was still heard. the dealer recommended that the contact install carpet to cut down on the noise. the final problem was with a loss of rear traction. the dealer has been unsuccessful in identifying the root of the traction problem.*ak the cruise control stopped working. updatd 11/29/05. *jb | |||

| When coming up to an intersection, the truck failed to come to a complete stop, in dry conditions, with ample stopping distance. the truck was revving at a high rpm, and continued to push forward with the brake pedal pushed as hard as possible. this resulted in a rolling collision. vehicle finally stopped when shifted into park. immediately called dealership, and gm. after 2 days in the dealership they stated nothing is wrong, and will not investigate any further. i will not drive the vehicle any longer after this scary incident.*jb | |||

| I own a 2003 chevrolet silverado extended cab short box z71 4x4 pick up truck. it has the 4 speed automatic with overdrive transmission. i have a consistant shifting driveline clunk that only occurs when the transmission upshifts from 2nd to 3rd gear and then downshifts from 3rd to 2nd gear. i have had this vehicle back to the chevrolet dealer three times so far concerning this issue. all i get is the usual gm runaround that this problem is a normal condition and no repairs should be attempted according to the tsb related to this condition. i have owned other gm vehicles in the past, and i have never had of any of them bang or clunk from the transmission when shifting gears automatically. they claim that it is some type of a momentary torque reversal problem when that particular shift occurs that causes the clunking and or banging condition in their transmission. a momentary torque reversal in their drivetrain while the vehicle is moving in forward gears is a normal condition? not to me. they absolutely will not fix this problem under warranty stating that it is a normal condition. on the other hand, if this causes the transmission to suddenly lock up...and someone gets hurt in the process....then i'm sure that it will be fixed properly. why is it that the automotive manufacturers today will not repair their engineered screwups at their expense, like they should be responsible to do? why is it that they will not fix their problems unless that componet in question fails completely? | |||

| 2003 and up chevrolet silverado 1500 4.8l automatic i found i am able to shift the transmission out of park without the engine running and with the key in the accessory position. this is from no key inserted to inserting key and rotating to the accessory without going to the run or start positions. this can be done without depressing the brake pedal. this has also been verified on numerous 2003, 2004 and 2005 silverados with automatic transmission but unknown engines at several dealerships. i was told everytime this is normal operation but was unknown to them prior to me bringing the problem up to them. this problem is consistent and occurs everytime attempted. possible scenerio involves children in the vehicle with the key set to the accesory position to permit the radio to play while the driver exits to perform some task. the children could hit the shift lever and move it out of park permitting the vehicle to move. again, this is possible without the engine running and without the brake pedal depressed. with the key in the run position, the brake pedal must be depressed to move the shift lever but never with the key in the accessory position. | |||

| Very excessive drivetrain clunk while down shifting 3-2 gear, upshift 2-3 and now is getting worse as 1-2 and 2-1 are clunking due to excessive drive train freeplay. the problem is aggarvated rounding slow cornors, down a grade or with a load. the dealer tried to made me believe i was hearing things and everthing is fine the first time in, yet everyone who rides in it asks whats that banging. the second time in the dealer for the problem i got a tech service bulletin, which says owners may find the clunk objectionable?? will not adversely affect durability??? there is no way this drivetrain will last as long as a nonclunker. the dealer was also going to get me an extended warranty for drivetrain, which didn't happen. very frustrated chevy won't fix it. if owners find it objectionable it should be fix. *ak | |||

| I purchased a new chevrolet silverado truck on 8/15/2003. i drove it 15,000 miles and the transmission went out and was replaced. on another trip returning from denver to durango i was driving on a mountain road when the back wheels suddenly, without warning locked up. this caused the truck to go into an uncontrolled skid and i crashed into the side of the mountain. the truck bounced back into the road and almost forced other cars off the highway. the opposite side of the highway was very steep with no guardrail. had i skidded that direction, i would have tumbled some 200 feet or more. to add to this the airbags did not deploy upon direct frontal impact with the mountain. all of this information was noted in the colorado highway patrol accident report # 908fzeh21p. general motors has accepted responsibility but 10+ weeks later has not replaced the totaled truck!*ak | |||

| Service 4 wd light comes on while towing trailer. i've taken the vehicle to 3 different dealerships 4 different times and always find something new creating the problem. per bbb order chevrolet was to have another opportunity to fix vehicle and chevrolet rep. insisted that he would personally have a allison transmission guru personally review my vehicle. well they changes some sort of part within the drivetrain and the guru never showed up. to this day the 4 wd light continues to come on and they seem to just call it a minor flaw and i have driven the vehicle to much! i purchased the truck just about a year and a half ago and it has 48000 miles. i guess i'm just not allowed to drive the truck that much. i'm just lost since they say the lemon law is good for 18000 miles only and i'm stuck with the truck. please help with some info!!! *jb | |||

| On the advice of council, i have been instructed to outline and document to general motors corp. details concerning a vehicle incident that took place on january 29, 2004, approximately 7:45 pm, while driving our 2003 chevy silverado 2500hd (vin#1gchk29u03e369348) my wife and i were driving on s.r. 224 east of findlay at 40mph when without warning, the entire front end locked up on the vehicle (later duplicated by the service technician at lariche chevrolet in findlay, ohio) throwing my wife and i violently against our restraints. this resulted in a total loss of control and inability to move the vehicle from oncoming traffic. we were stranded in the middle of a road that is frequented by semi trailers and vehicles traveling in the 55-60mph range, and were completely unable to get the vehicle to move. the vehicle would not go forward or backward. after pushing the 2wd/4wd buttons frantically on the dash and shifting from park to reverse to drive, the vehicle finally moved in reverse (2wd). i then shifted to drive and was able to pull into a nearby driveway. after testing the vehicle up and down the driveway, we proceeded to get off the main road and went directly home (approximately 0.5 miles). the vehicle was towed to lariche chevrolet the following morning. (complete background of service work in memo page) as you can see this was a terrifying experience for both of us, leaving my wife unwilling to travel in this vehicle. fortunately, our problem was duplicated by a technician at lariche chevrolet who in the manager's words your truck about put my service tech through the windshield. because we are afraid to ride in this vehicle, we are asking to have chevrolet exchange this vehicle with another equivalent model. this was our second chevrolet in 2 years, so we are happy with the brand, just not this truck. please advise us of your decision. *ak | |||

| On one occasion the viehicle shifted into towing mode by itself, without any reason, (ie: no buttons pressed). yesterday, the truck shifted into 4wd - low range at highway speed by itself without any reason. this caused the front wheels to temporarily screech and the engine to over-rev. i stopped the truck on the side of the road, turned it off and then the 4wd control panel was inoperative and the service 4wd indicator was on. i took the truck to my local dealer, they told me they didn't have time to diagnose the problem right then, but not to worry because the error code would be stored and they could retrieve it after lunch. i took it back after lunch, and no error code. this is the third time i've had the truck in on 4wd problems, but the first time that the problems have presented a real danger. i had the truck in five times with transmission problems without a fix. *jb | |||

| The transfer case on my 2003 silverado 3500, on its own, switches from 2 wheel drive to low range 4 wheel drive while at speed. the dealer advises that gm has no fix for this dangerous problem and, instead, has had me remove the fuse to the on-the-fly 4 wheel drive. this leaves me with a 2 wheel drive vehicle only. the problem is constant once it starts. at 35 to 45 mph, control is difficult when you are surprised by this drastic shift to low range 4x4. my brother and i bought two identicle vehicles in december 2002 and his is doing the same thing. gm and the dealer have been of absolutely no assistance at all. the problem continues and has very serious potential. | |||
