A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.
I was driving a GMC sierra 2500 (2015) truck on a road (speed limit 65 MPH) and was stopped to make a left-hand turn into a state part. A driver hit me in the rear at a high speed. The powder from the airbag compartments filled the truck cap but the air bags did not deploy.
On 5/12/19 the check battery charging system light came on, so I left out side facing street in case I had to jump to take to dealer on monday. I went in the house and 1/2 hour later heard and explosion and went out and the truck engine compartment was on fire.
I bought a new 2015 GMC double cab 2500 hd z71 4x4 pick up truck in may 2015 it has factory equipped lt 265x70x17 bridgestone duravis 7 ply tires. I took it on a unloaded 9000 mile road trip after about 7000 miles I noticed the truck was not handling like it should it wanted to go straight thru curves it wondered and pulled left or right. I took it to the GMC dealer in spokane washington the found that the alignment tow-in and right side caster was off.
The headlights are so dim the truck is dangerous to drive at night. I drove in a snow storm last night and I couldn't see ahead of me. I was driving on a highway at 45MPH.
