When I press on the brakes, it feels as though the master cylinder is gone and it is the manual type drum brakes that has air in the line. It takes everything I have to press them and pray it stops!! the vehicle is always in motion when detecting this problem and seems to occur more repeatedly if the brakes are pump quickly in succession before applying brakes or when the brakes are pressed for an extended amount of time then you release and repress it want stop. Another issue is my lane id warning. When turned on at the button, it just beeps at me and shows service light. When I first took it in with the problem, the dealership called me and said all fixed, but it did it before I left the parking lot. They had my truck all day for the issue, put me out of a vehicle and then said they would need for extended time to repair but didn't know there was problem. How do you make that determination when you told me its repaired. I just turned it off and haven't used in 2 years.

3 Seats problem

Failure Date: 07/17/2017

My driver's seat became loose approximately 2 weeks ago (7/17/17). It has become progressively worse, to the point where I can feel my seat shifting when I turn or accelerate. I am worried that in the event of a wreck, my seat may become a projectile. I took my truck into the dealership in waco, TX on 7/31/17, and the dealership has stated (today, 8/1/17) that this condition is not covered by any warranty program, which I find disappointing and frustrating. I have read multiple reports of this same condition in gm trucks from 2014 - 2015 year models.

4 Seats problem

Failure Date: 07/01/2016

Over the summer the drivers seat in my truck started making a clicking sound and felt like the base was shifting, almost like a bolt was coming loose and the base was sliding on the threads. I took it to the dealer and described what was happening, they drove it and decided that they needed to install a shim kit to repair the problem. They installed the kit and now a few months later it is starting to do it again. How safe is it to have shims under the seat to tighten things up when that seat is what it supposed to hold you in the vehicle in the case of a collision. I am taking it back to my dealer to have them re-repair it but are shims even safe under the seat or is this just gms money saving solution to get consumers off their back while putting their safety at risk?.

I purchased a GMC sierra 2015 regular cab from your company representative, aljomaih automotive company in the kingdom of saudi arabia. However, after a few months, I discovered that the vehicle had several defects, and it exposes its users to serious threat. After that, ministry of commerce in kingdom of saudi arabia has made several callsfor users of the same vehicle that they have to check with the representativeto fix the defect for free. However, the representative temporized and evaded, then I had to file a lawsuit against aljomaih automotive company, general motors’s representative in the kingdom of saudi arabia. The court ordered the experts' department to checkthe vehicle by five specialized workshops, and reports were issued unanimously on the following: "the defect in the mentioned vehicle is a factory defect, which was found in all vehicles of the same type and not only the mentioned vehicle". Also, I have submitted report to the court from the general motors website proving that the mentioned vehicle is faulty with three other defects. As well as, all six calls were issued by the ministry of commerce, including the mentioned vehicle, with the chassis number.
