“I was driving on the freeway going at the speed of traffic about 65-70mph then suddenly I heard my car engine slowing down and multiple lights popped up on my dashboard. I looked at my speedometer and it indeed was decreasing in speed. I tried to accelerate little by little and it did not. My check brake system, check brake hold system, check power steering system, check VSA system, check hillstart assist system, check emission system lights popped up on my dashboard. My car felt like I was popping the clutch, jerking a lot. I was able to move over to the right shoulder and park. I turned the car off and I was able to turn it back on unfortunately but the lights were still popping up and my car kept jerking and not accelerating. This happened while driving on the highway this is extremely dangerous! There has been others with the same issue.”

“The car is constantly throwing codes for faulty emissions system problem and parking brake problem but the car runs fine. The dealership will not do anything unless I pay them a fee to diagnose it and then they suggest replacing the catalytic converter even though it’s very likely a faulty fuel hose or faulty sensor. This needs to be recalled and fixed immediately”
