( popping sound coming from under my seat in 2017)these are all issues that happen while driving. I am getting on the on ramp for the highway and my car will not go pass 35 mph for over 15 seconds, even if I floor it. There is on coming traffic doing 60 to 70 mph and that is a life or death situation. I have no way of moving to avoid being hit. My car will stall when I try to drive after stopping at a stop light.
