What owners say
The fuel pump has an active recall. Took itin to dealer and we are being advised kia will not cover the cost. They have an article out that clearly states they will cover the costs. The car wreaks of the smell of gas and we are scared it will catch fire.
purchased my car in june of 2019. Ive scheduled regular oil changes and maintenance until june of 2020 where the engine light began to flicker and the car would shake. I took to Koons Kia owings mills md and it was repaired. Next year same thing. Oil compression issues all year round where i have to keep putting oil in. Now my car starts and shakes violently. the kia service modurator on the car indicated there were an engine issue. I cannot keep dishing money into this car with so many recalls (current fuel pump recall and anti theft issue) is also included. Please help
High injector fuel pump top engine mount went out at 68000 miles. It caused the vehicle to stall and lose power and basically cut the car off while driving.
My car had been consuming 2 quarts every 1,000 miles for the past 3-4 months and the kia dealership told me that the best thing i could do is keep getting an oil change. So one day i tried starting my car and it starting shaking and turned off so i turned it back on and it shut off again. I jump started it and it shut off again and i jump started it again but it never turned on. All of the problems that i have has been confirmed by the dealership (Open Road Automotive) My engine is all the way messed up, my fuel pump was messed up .My engine light came on after this and i just keep having problems with my car. I seen that kia keeps having these problems but i chose to get my car anyways because I love kias cars but I will have to switch if these problems are not solved with my car and i get new parts on my car because these are failing parts not because of me. I’m having So many problems with my car right now and it’s been costing me a lot of money .It’s at the shop right now and it’s been at the shop for maybe 2 weeks now. I can’t get a rental because they are only covering $40 a day and they are charging me $200 a day. So please help me with these problems and get these problems fixed.
