Open the full vehicle complaint log (all categories)While entering the highway on ramp, as I accelerated and turned on the left turn signal, the engine stopped. The steering became very hard. I stopped, put the transmission in park and started the engine, with no problems. This is the second time in3 months this has happened when turning to the left, and activating the turn signal. In both cases, the auto headlight dimming warning lite came on. The car is well maintained, and has never been damaged in any way. The weather was clear.
