GMC Complaints

I took my 2017 GMC Sierra 1500 SLE in to my local dealer because the engine was misfiring and there was a loud ticking noise coming from the engine. There was a sudden onset of loss of power, sluggish acceleration and shuttering. The dealership technicians did their diagnostics and found "cyl 1 miss fire removed valve cover and rocker arm found cyl 1 intake push rod bent replaced cyl 1 rocker arm push rods and all driver side lifters re[placed v loam resealed all 8 injectors cleared code miss fire is cured." This is a known GM issue as pursuant to service bulletin 15-06-01-002L. Upon further research from other complaints it was reveled to be caused by KNOWN defective or sub-par components being continually installed in GM vehicles. GM has knowledge of this issue and should take ownership of their shawty and deceptive work practices.
