I have read the comments that were written after mine on Oct. 11, 2001. Most of the brake complaints are exactly what my daughter tried to have fixed before her accident.

PLEASE insist that GMC fix the ABS (anti-lock brake system) before it causes you grief also. GMC knows about this problem and everything else wrong with the 1999 Sierra.

I have something to ask of the readers and it is important to so many owners of this truck. If you have had an accident, causing injury or death, while in a 1999 GMC Sierra please email me. Or even if you know someone that has had an accident with injuries while in this truck I need to know. The one point that is crucial, right now, is that the owner had to be a resident of Texas at the time.

Thank you and good luck with your vehicles. Remember, the consumer MUST have rights or we all lose.

I like so many others have a 1999 GMC Sierra 1/2 ton truck, it has 63,000 miles at this time having spents it's life so far on paved Highways. Recently the ABS Brake light came on and a roaring that continued despite turning the ignition off which I traced to a running (motor?) beneath my truck. Luckily my father knew how to disconnect it saving my battery. I have owned a Chevy or GMC truck since I bought my first vehicle, but believe it might be time for a change. That General Motors has to know of the defect in the ABS Module, requiring it's replacement with a cost of up to $800 and yet does not issue a recall is insupportable. Does anyone know a consumer or government department we could write to in order to put pressure on General Motors to issue a recall-please email me or post here if you do. Thanks TK, person2person_2000@yahoo.com.

We own a '99 Sierra Z71. Had at lest 3 recalls in a year for minor things. The drivers side power window motor went out, (and guess what, it is acting up again,) had to have the steering column worked on, had to replace the battery due to something under the hood staying on and replace that part too. A lot of nickle and dime repairs.

It now has only 53,000 miles on it. Recently the security light started coming on while driving, then there were times when it wouldn't start then maybe 10 or 15 minutes later it would start. We took it in and come to find out there is a problem in the security and the ignition. It will cost over $500 to fix it. Of course our warranty has run out and there is no recall on these problems. GMC has no recalls on the big ticket items naturally. Just wondering if anyone else has had this problem yet? All I can say is if your security light comes on while driving and it gets to where it starts when it feels like it... get ready to open your wallet.

We'll never buy another GMC again. They don't stand behind their product.

I have a 1999 GMC Sierra and for the most part it is a great truck. My Issue is with the Security light coming on while driving and once vehicle is shut off it won't start for about fifteen minutes. I had this problem in June of 04 and had the ignition and lock cylinder replaced. and although it fixed the problem it cost me $500 to do. Here it is October (only four months later) and I am having the same problem all over again. This is getting ridiculous and very inconvenient. The part is covered by warranty, but I am jumping through hoops dealing with GM to fix it. They are trying everything possible to get out of it. Hopefully this will be the last time I have to deal with this.

I have a 2001 Sierra 1500 with 89,000 miles and it has been pretty reliable mechanically - none of the aforementioned problems. The corrosion protection however has been another story - rusty chassis and the bottom seams of the doors rusting in less than 3 years from new (no seam sealer at the factory). I work my truck pretty hard - towing a large boat frequently.

The boat dealer I buy my boats from runs Suburbans - towing boats of all sizes many many miles. He owns 4 suburbans - towing with them to between 300,000 miles and 350,000 miles - then he puts a plow on them. He just retired a suburban from towing duty with 465,000 miles on the original drive train - now he plows with it.

I was the owner of a '99, until a illegal, unlicensed, and not insured "driver" hit it. Generally, it drove exceptionally well. For a truck of its size, the brakes lasted a reasonable amount of time. As to be expected, a few problems were encountered (such as the exterior door handle broke.) Overall, I was pleased with the vehicle; in fact, I plan to purchase another.

Side note: my brother had a Toyota that had a cracked block. Six months at the dealership, the dealer finally repaired it with a new engine.

I have a 99 GMC Sierra four wheel drive.

Have had the steering clunking noises for the last 15,000 miles.

The ABS unit failed at 22,000 miles. I was told by a candid GMC mechanic that it should had been recalled as they pretty much all fail.

The drive line clunks badly at times.

The truck has never been off road and is gently used. It now has 42,000 miles and I use it sparingly as I don't have confidence in the vehicle.

Hard to believe GM now wants our tax dollars to bail them out. With enough crooked politicians on their payroll they will likely get the money. I doubt it will keep them in business however. Poor quality catches up with you sooner or later.

I have had my 1999 GMC for two years, purchased it used and I have to say that it has been an excellent truck. I have the 5.7 engine, and man does it run like a top. I have 170000 miles on her now, and with no major problems. I have replaced the alternator and fuel pump, but other than that, it has been a great truck.

Read the comments and they are bang on. 1999 GMC Sierra, bought it new, rear brakes and rotors, lost track of how many times they were replaced, ABS pump /sensor dead, unplugged it.

Ball joints, heater switch, 4 wheel drive switch, all dead. But the truck runs great and sucks gas like it's free. Any wonder GMC went broke. Next truck will be a Tundra!

I have a 99 GMC Serria and I hate the truck. But it starts really crazy and it clunks in the rear end. I really think that Ford make a better truck. I have owned GMC and Ford and Ford will out last a Chevy or GMC. I am going trade my GMC for a Ford.

It sounds like to me many of the posters on the comment probably don't even own a GMC Sierra.

Who would file a lawsuit over a clunk in their drive axle? I own a 2000 GMC and yes I know the sound. I have known it since about 80,000 miles and I'm now pushing 130,000. The sound I thought was u joints has gotten no worse and caused me no problems.

This truck has been an extremely sound truck and I have seen what the competitors have to offer and their products are just as good, but have their problems too. Just ask my dad about his 98 F150. It was a great truck until the motor gave out at 130,000 miles! Or my Mitsubishi Raider that was reliable if you could stand a gutless truck that got 15 MPG.

My GMC has been a good truck, and yes I will buy another one.

I have a 1993 Chevrolet 1500 extended cab 4x4, and I was thinking about getting a newer truck with the 5.3 for a more reliable daily driver. The old one has over 350,000Km, and now I know I won't be going for the newer one... holy god, that's a lot of serious expensive problems. I'll keep my TBI 350 and 4L60E transmission... the new one is a hand grenade.

My 97 GMC has the same problem.
