“I was driving in town through a stoplight when I noticed my brakes stopped working. Also when I had stopped the car still in drive and the car had shut off completely in the middle of the road and was not able to turn back on. The car would keep trying start but none were successful. My car also stated that there was reduced power to the engine and the car would hesitate to gain speed as well. My safety and others were put to risk because my brakes stopped working so I could’ve caused an accident. When we trying to find what was wrong with it through a code reader we had noticed the piece had shattered inside of the engine. No insurance, police or manufacturer has inspected the issue.”

“A software error in 1.5L turbo model disable fuel injectors, preventing the engine from starting or causing a sudden stall while driving. It’s been confirmed to be an previously opened recall that was fixed by previous owner. But, is happening again to me. Yet I’m being told It has been closed and cannot be fixed unless I pay out of pocket. There are warning signs that pop up like reduced speed while I am driving etc. which reduces my speed and is incredibly unsafe.”

“The check engine light keeps coming on and off with a warning that the engine power is being reduced. The dealership's service center can't locate the issue. The car's traction warning went off and the car's speed was reduced while driving. This happened twice in the same day. When you shut the car off and turn it back on the warning goes away and the car drives normal. This is very unsafe. Had this happened on the highway there could have been a serious accident.”
