    Car hesitant to crank, once the Start/ stop button is pushed, the car will start, run smooth for a second or two then start to shake and putter like it’s not getting fuel and loses it power and cuts off. I have to go through this process 5/6 times before the car will stay crunk. While driving Car will out the blue say reduced engine power and acts as if it does not want to pull or it is losing power! The car also has the eco saving feature where it cuts off at every stop and there is not an option be turned off and car is hesitant to start back up after it cuts off. Car is now starting to smoke from the tailpipe. The VVT intake and exhaust solienoids have oil getting into them and the PCV valve is about to crack open. The car throws codes like rich fuel intake, something to do with the catalytic system (in which I’ve put a brand new catalytic converter on the car and it did not solve the issue) it also throws codes about a throttle and cam sensors and a few more codes.. I see where there are recalls for the (same make, model,year, and engine size) but my cars VIN is not included with the recall! Can we please get this as I need my car and need this issue fixed as soon as possible as it is dangerous for me and my 2 year to travel in this vehicle.

    Driving normal. Upon application of brakes, brake pedal became stiff and brakes did not function normal. Had to apply immense pressure to stop and it sounded like brakes kept locking up. Vacuum pump that supplies vacuum for engine with turbo to function, along with the brake booster to be able to apply normal braking power, was destroyed. The inside of the vacuum pump is in pieces and part of the bushing that connects into the engine was broken. Caused by faulty vacuum pump, or faulty cam shaft. If this had happened while in traffic, it is likely a crash would have happened. Damage caused to the vacuum pump resulted in metal pieces in the engine block as well.

    Since I got the car, if I let it go in auto stop, it has a hard time accelerating when I push the gas. It has gotten worse and now it has a hard time accelerating in general. When I push the gas it sounds really loud like it’s struggling to go. I realized this is a safety issue for me and others when my car wasn’t going at the light of a busy intersection, or when I’m getting onto a highway and my car isn’t picking up speed. This makes it scary for people already on the highway as Iam causing them to brake unexpectedly. Every time my check engine light comes on I take it to the dealership. It’s been taken in for repairs multiple times but this issue still keeps coming back.

    My car keeps saying please put in park, even after the car is parked. If I don’t turn on and off the car multiple times shifting from park to reverse to get it to not say put in park, my lights in my car stay on and the battery will eventually die. Seems electrical, and afraid of it says please put in park, is it really in park if it says that?
