NHTSA Complaint #11481350 — 2015 GMC TERRAIN

My vehicle had lack of engine excelleration, hesitated and was hard to drive. Took it to the GMC dealership and was told it was the timing chains. Because this was my only car and needed transportation for work I had it repaired. The amount was an expensive repair of $2,219.71 for what I researched was something that was happening in many of the 2015 GMC Terrains. People have been trying to get a recall notice to be sent to owners because it is so common and dangerous. I could be out on a busy highway and having the car die on me. Is there a way to receive some compensation for this seeming to be a normal problem for these cars. Why is there no recall especially since it has happened in many many of these 2015 GMC vehicles
