“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. …”
NHTSA complaint #11297994, filed 2020-01, 10 miles“The vehicle always has a smell of dampness after a rain. Somehow water is getting into the vehicle. I have replaced the seal around the third-brake light which was thought to be the culprit, but no fix. The rear seat metal has rust on them from the damp. The driver's seat creaks when making turns. It is like it about to come apart. There should be a recall on this. People could get hurt if it happens. Le under the vehicle, I noticed that a body-mount is missing under the driver's side. This could be the reasons for the creaking. I am not sure!”
NHTSA complaint #11383281, filed 2020-12, 90,000 miles“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.”
NHTSA complaint #11011999, filed 2017-08, 37,500 miles“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. …”
NHTSA complaint #11153931, filed 2018-11, 62,000 miles“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. …”
