On Friday, may 31, 2019, while driving home from work, I noticed my vehicle began to shake while driving. (car has 14k miles) I called gossett Hyundai at covington pike and was told it was probably a rotor or a spark plug and to bring it in Saturday morning. Saturday morning, while driving to the dealership, the bluelink lit up saying my car needed to be serviced. I drove the vehicle to gossett Hyundai at mt. Moriah. After going back and forth (in front of the tech) they agreed to run a diagnostic (because I told them I was worried about driving my car to the covington pike location), and the tech informed me that he was a tech and he could run the diagnostic. After running the diagnostic, I was told that one of my cylinders was not firing. After some period of time, they located an ignition coil in the parts room and replaced it. The car still was not running correctly, I was informed that the car needed a spark plug but they wouldn't have one until Tuesday, June 4, 2019. After the dealership received the spark plug and installed it (I guess?), the car was still shaking and not running correctly. Sometime June 5 or 6th, they called Hyundai manufacturing and have been receiving instruction from the manufacturer directly to run leak tests. I was informed that they also used a camera to look down in the cylinder and that it has �scarring� which could be from fluid getting inside? I have also been told that it is probable that my car will need a complete new engine. It has been 2 weeks and the dealership is working closely with the manufacturer to see what needs to be done.

I want to have all changed after the oil was changed the engine light came on in the car I wanted to stall.

Dealer installed download #953 pursuant to a Hyundai recall. Afterwards the car went into "limp" mode as if there was a problem, and cannot be driven. Dealer does not know how to fix this, and is holding my car and waiting for Hyundai in California to come up with one. Mine was second car that morning that this happened to.
