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?

This complaint is in regard to NHTSA campaign 16V209000 in regard to a seatbelt recall on 2014/15 GMC Sierra. GM has proposed 2 solutions: One for new unsold vehicles which leaves a seamless repair and the other for used vehicles that leaves the seat visibly damaged. This visible damage has led to owners not having their vehicles serviced and opting out of this recall. You can find examples and evidence of these owners here: www.GM-trucks.com/forums/topic/189628-seat-belt-recall/ www.GM-trucks.com/forums/topic/190371-happy-with-your-seatbelt-recall-fix/ the only reason that GM proposed to solutions is to save a few bucks at the expense of their customers. This is now leading to a potentially dangerous scenarios for GMC owners and others on the highway. This needs to be investigated and GM needs to answer why they proposed a cheaper less effective solution which leave visible damage to the vehicle for current owners.

Rear seat headrests too low to be safe and effective in crash. They are both too small and to not stay locked in the far up position. Vehicle has been to the dealership multiple times for issue to be reviewed. At this time dealership claims headrest function is normal.
