I have a 1999 gmc sierra extended cad truck the drivers seat adjustment made of plastic when it breaks the seat will not lock. The seat belt is attached to the seat so in the event of an accident all that is holding is flimsy plastic. I checked all the salvage yards in my area they said every truck that they have that has wrecked the plastic slide is broken. To me, my wife and my life are worth more than this plastic piece. Gm needs to recall and either fix this piece with metal or different seat tracks. My seat broke just adjusting it.

1-seat adjustment 2-seat will not lock in position-slides freely front to back 3-temporarily locked failed piece into usable position-cannot adjust to any other position due to failed plastic block. Researched complaints for 99 gmc sierra truck and found 10 existing identical failures. These are complaints-566049, 758819, 855016, 862903, 877718, 10020665, 10022698, 10066125, 10074822. I am sure there will be additional complaints under "mirror" vehicles such as chevrolet and cadilac and other years. I have identified the piece as a plastic block approximately 1 inch wide by 2.5 inches long with a lever, spring and pin assembly. The "u" portion of this block fails causing the seat to slide freely creating a severe safety issue. This is clearly an unsafe and poor design. I have pieces of broken block for reference and will continue to escalate this as far as necessary for resolution from gm.

The drivers seat adjuster fails to hold the seat from sliding back and forth. I have manual bucket seats and have been told by gmc that there is no records of failures. This has been repaired 5 times by replacing the seat adjuster, all under warranty thus far, but I am concerned that this is a safety issue since if it fails while driving, it allows the driver to be moved forward when brakes are applied.

There is a bar that is at the base of the front drivers seat which comes out at the console. The bar cut straight through the seat. The bar is very sharp, and the consumer was badly cut by the bar . *ak

As I was driving down the highway I had to apply my brakes very quickly and a part in the manual adjusted drivers seat broke and the seat slid forward pushing me against the steering wheel. After this incident the seat will not lock in any position (it slides free in the track). I reported this to gm and they equated it with brakes wearing out. I am so very thankful to the lord that nothing was coming because when the seat malfunctioned my ability to steer and continue braking was affected.

While approaching a stop sign at approximately 20 MPH, the driver side seat adjustment broke free and the seat slid forward. Because of the anchorage of the seat belt being the seat itself, nothing held me back from contact with the steering wheel. Fortunately this happened at a low rate of speed. I am in the process of seeking reimbursement for repair cost in the amount of $513.11 from gm who would not cover the repair because the vehicle is out of warranty.
