(reported on)

Sonata

  • miles
While driving rpms go up high, idle will not drop. Vehicle accelerated suddenly and unexpectedly without warning. Car drives over 40 without foot on gas. Hard time braking because engine is too high. Has been going on since had car. Dealer adjusted cable and didn't work. Almost went thru dealer wall when bringing it in for repair. Is in repair shop again because problem was not fixed. Car is unsafe and had near collisions.
