Driving on the highway at 65mph, engine light started blinking then stayed solid and my speed declined to 40mph and would not go higher. Had to stay in slow lane to get off and get back on to make it home. I was unsure as to what was happening.It was the weekend so had to wait until Monday until i could find out and the dealership told me it was the valve cover gasket (which is brand new). I was also told they couldnt do anything else for me i need a long block assembly.
Had vehicle worked on, on 4/11/2023 ( oil change &tuneup). On 4/17/2023 exiting 151 Hwy vehicle slowed down on me, then regained speed to safety at a Shell gas station. Vehicle started with a loud noise coming from the engine compartment. Got worried, had vehicle towed home. Have been trying to get a hold of kia but they don't answer phone or hang up on me, since I have no warranty on vehicle cause I couldn't afford it. Just wanted to pay it off since I only needed One more year at 140011 miles on it. My first kia lasted longer than that. I currently owe under 3,500 on it. Need help please.
