general problems of the 1999 Chevrolet Silverado

The contact owns a 1999 Chevrolet Silverado. While driving approximately 35 mph hauling a trailer, the front and rear brake hydraulic lines failed. The contact was able to stop the vehicle by using the brakes on the trailer. The vehicle was taken to the dealer; however, the vehicle was not diagnosed or repaired. The contact, an experienced mechanic, diagnosed and replaced the brake lines. On a separate occasion while driving 50 mph, a plastic component of the driver's seat fractured and caused the seat to slide back and forth into the steering wheel. The failure was not repaired and the manufacturer was not notified. The failure mileage was 58,000. The VIN was not available.

While attempting to adjust the driver's seat in my 1999 Chevrolet Silverado pickup truck, I found the seat would not lock in place. Moving the seat back and forth in an effort to lock it, something appeared to break causing the seat to move quickly forward, pinning me against the steering wheel. I later found a small plastic fragment on the floor and assumed it was part of the track locking system. The seat now was completely free in its movement forward and backward, extending to the limit in each direction. I took the broken piece to a local dealer who explained that it was, indeed, part of the "seat adjustment" mechanism, and, when broken, the seat would move without restriction forward or backward. When I questioned why such a critical piece of equipment was not made of metal (instead of plastic), I was told that "yes, it should have been. " had this failure occurred while driving, it could have caused serious, if not fatal, consequences. Once the part breaks, any application of the brakes will immediately slam the driver forward into the steering wheel with considerable force. The opposite effect is also felt when accelerating. I was very fortunate that the part broke before I had left the curb. This is a very dangerous design and system. These parts should be manufactured from hardened steel instead of plastic material (even nylon. ) at best the surprised driver is immediately and totally distracted; at worst, he is totally incapable of maintaining control of his vehicle, being slammed forward and backward as he applies braking or acceleration. The cost of repair of this condition is approximately $400. And should not be borne by the consumer. General motors should address the type of material used in the manufacture of these parts for future vehicles, and recall and replace them on older models. Note: my vehicle has less than 56k miles.

The seat locking device broke while braking allowing the seat to rush forward. My knees hit the bottom of the dash. If I were in a high traffic area, a wreck may have occured.

Inferior white plastic part in driver's seat track of 1999 chevy Silverado 1500 failed, causing driver's seat to slam into steering wheel after quick stop at low speed. Gm svc. Says there are no other reported failures, I find this hard to believe.

Dirivers side seat failed to stay locked in position and slid forward when brake was applied. This cause me to be thrown foreward with all my weight on the brake petal. If not for the seat belt and no one following close behind it could have been very serious.

While driving home in my 1999 Silverado with manual control seats, I had an uncommanded release of the driver seat while braking. Upon investigation a part of the seat was found broken off and laying in the seat track. There was no adjustments performed to the seat prior to the failure occurring.

Driver's seat is no longer working properly. When the gas pedal is depressed seat slides backwards. When the brakes are depressed, the seat would slide forward. Consumer has made an appointment with the dealer to examine the problem. This problem has happened numerous times in the past six months.

Inner seat adjuster on driver's side broke on my '99 chev Silverado extended cab truck, having 34,000 miles, allowing seat to move forward and backward on rails without restriction. Seat belt is part of seat thereby resulting in the driver to be moving forward and backward on seat rails without restriction. Seat of course does stop in the further most backward and forward ends of seat rail. Chev dealer lists part as "inner adjuster" part #14691. The part is sold as a whole according to the dealer and retails at about $149. 00. What appeared to break was a plastic piece that fits in the rail and which would seem to be the part that halts the seat in the position chosen by the occupant. I still have the broken piece as recovered from my floor board. I had been having problems for a week or so with the seat not moving forward and backward when attempted by adjustment lever. I assumed I had something under the seat impeding movement, but was actually due to the aforementioned problem.

Drivers seat locking mechanism broke. When brakes were applied, driver was thrust against steering wheel. Seatbelts do not help as they are attached to the seat. Seat slides forward and backward freely. I feel this is a severe safety concern due to the fact that you cannot control the vehicle when you are unable to stop the seat from flying you forward. The locking mechanism should never break. The Chevrolet dealer calls this a seat adjuster, but is a piece of plastic that has the locking pin in it. A piece of plastic to hold a seat in its place is totally stupid.

Front drivers seat will not slide all the way back after you have tilted it forward and put it back. It seems to hang and not move backward until you play around with it. Then the seat will not lock in place when you make an adjustment, then you have to kind of force it into a locked position. Also the seat rail has looseness in it. It fails every time you make a seat adjustment.

Drivers seat failed to lock into position, this was second occurrence. When brakes were applied, driver was thrust against steering wheel hitting chest and face and injuring wrist, knees hit the dash, seat ran onto left foot. Seatbelts do not help as they are attached to the seat. When driving, seat slides forward and backward freely. When the brakes are applied the seat slides forward, causing the foot to hit the brakes harder, thereby causing an abrupt stop. Luckily my children who were passengers at the time had their seatbelts on or they would have hit the dash. Most vehicles never have this occur in their lifetime, but this has happened twice within a year and a half. First time was August of 2000. Cost to replace is over $500. I feel this is a severe safety concern due to the fact that you cannot control the vehicle when operating, especially when stopping. The seatbelts don't help as they are attached to the seat. Major concern for me is if I am in an accident these brackets will not hold!!! I am a 120 pound woman, I do not adjust the seat often, I keep it positioned all the way to the back. My normal wear and tear could not have caused these railings to break. I have children who will be coming of age to drive. What would happen to a less experience driver? what if passengers didn't have seatbelts on? what if I was hauling a trailer? what of the force of the added weight of the trailer when stopping? what of the contents on that trailer? what if I have a minor accident, say a rear end collision, will my seat hold me in place? I don't have faith they will! because this has happened twice within a short period of time and on a fairly new vehicle, I believe the dealership or chevy should repair at no cost to me. There are no airbags that inflate for protection, it is a solid impact. If someone from chevy should hit their steering wheel one time like I did, I think they'd take this issue very seriously.

Would have no abs brakes after pressing on brake pedal. Had fuse removed due to abs pump continuing to run. Abs module had shorted out. Have taken to mechanic, but warranty expired. Drivers side window will not roll up, there was a popping noise when backing up and turning, dealer replaced lower ball joint, passenger side window leaks, leather seats are torn, cruise control module was replaced, dash panel parts inoperative, also cup holder rattles and the right back window leaks.

Was trying to adjust driver's lumbar seat with lever when lever broke in half. Pulled vehicle over to check out seat. Noticed a piece of white plastic with metal inside was broken.

Driver's seat separated from track, causing seat to move unexpectedly when applying accelerator or brakes. Dealer was inspecting vehicle.

No summary listed for above vehicle.

Two plastic pieces cracked which caused the driver's seat to move forward and backward. This could cause loss of vehicle control and result in a crash. .

Driver seat bottom would move forward while driving. Dealer replaced seat adjuster.

Lock for drivers seat has failed twice.

Drivers seat will not lock in place at after locking piece broke during regular use. Seat moves forward and back as you brake and accelerate.

Has been out of service for 15 days in less than 1 yr. Vibrations, comp reprogrammed 2 or 3 times now mileage decreased, clunks from rear end and on left turns, padding in seat failed, rear slider frame cracked and leaks. Dealer got replacement windows but they were cracked too. Still not fixed. Dealer couldn't fix some after repeated tries, had to go to another dealer to finally get some fixed. Side view mirror glass fell out. What's this truck going to be like a year from now?.

Driver's side seat will not slide back or forward or will stick in one position on sliding rail. Contacted dealer.

The front driver's side seat slide forward while stopping at a stop sign. I stopped and could not get it to latch back in place which is difficult since I am some what tall and had to use my left leg to brace my self so I would not slide forwrad the rest of the way. The abs light came on while driving home upon arriving home I got out and heard a noise which seemed to be coming from under the driver's side door. I let it go for a while about two days and it ran the battery down causing me to have it jump started since then I have pulled the fuse to the abs in the fuse box to turn whatever was running off. Dt.
