When I accelerate from a stop (at a red light to green) and "go" before I reach 10mph. . The car suddenly pauses and shakes (as though it's shifting in gear and gets stuck in a low gear) and is not smooth but shakes the whole car. Also, on the highway. . . . The car would suddenly go into low gear. . . And (again, I don't have stick shift) I press the accelerator and I can hear the engine burning. . . . Cause I can't go over 25 mph. So I have to pull over and turn the engine off and turn it back on. Another issue is the front bumper has a silver plate at the corners of the front car. I have replaced it 3 times cause it falls off. . . . So annoying!!!!!!!! worse than a wheel rim plate falling off.
