'tamara recall' I owed the vehicle for not even 1 year after financing it from a used car lot. I drove the vehicle from my home town Colorado springs to fort riley ks after purchasing vehicle. This is where I was stationed. I drove from fort riley ks to albuquerque nm for easter in April 2017 to visit family. When I returned home it started shaking and making noises and check engine light came on. The error codes were read and indicated it was a cylinder misfire. The same time this issue happened I got a recall for metal shavings in engine crankshaft. I took vehicle to Kia and they said they will not fix the recall until the cylinder misfire is fixed. They recommended a completely new engine. If I buy a whole new engine then they get out of doing the recall. I was then deployed to poland for 1 year and recently returned and there is still nothing done about it. Sounds kinda fishy to me. Kia is heating around the bush. I can not even drive the vehicle.

I drove my vehicle home from work (12 miles), parked in my driveway (vehicle turned off, not running) and walked inside. I sat down and within a couple of minutes I heard a loud pop, I looked outside to see flames coming from under the hood of my car. By the time the fire department arrived and put out the fire, the car had burned to the ground and had melted all of the siding off of the front of my garage.

While my family and I were driving home at a speed of 45mph we lost engine power and brakes. Upon the vehicle finally stopping, black smoke began to pour out of the engine compartment. We immediately exited the vehicle and saw flames begin to spread from the engine. We were notified by an off duty deputy that he was going the opposite direction when he saw us with a fire underneath our vehicle while still moving. The vehicle ultimately went up in flames along with everything we had inside.

We bought this car brand new in 2012. It is 6 years old. We were notified of an engine related recall in 2017. We took the car in to get the recall (s) looked at (there were 3 other recalls too) in October 2017. They notified us that our engine was fine and did not need replaced. In May 2018 I was driving in a 70 mph area of the interstate, tried to accelerate, heard a loud clicking sound, all of the warning lights come on and the engine turned off. I turned on the hazard lights and was able to coast to the shoulder, luckily the traffic around me was light and two young children were not in the car with me. The car is right outside of the warranty period. I no longer have a vehicle, even though I just bought a brand new car that is only 6 years old. I am extremely disappointed in Kia and will never recommend buying a Kia.

My car has a knocking noise in the engine, the car was taken to the dealership to get inspected for the recall September 2017. Team Kia of el cajon; the dealership said that the salvage titles aren't covered under recall warranty. 4/18/2018 while driving in the fast moving traffic, my car's engine shut off. After meeting with the mechanic today I was told the engine went out. These signs indicate to me that the engine went bad due to the recall issue that the dealership refused to replace. I've owned the car for less than a year and provided preventative maintenance on the car at the scheduled times. Prior to purchasing the vechile the car received a engine clearance through Kia dealership and through my private mechanic, saying the engine was good. Now 8 months later after hearing continuous knocking noise and almost getting into an accident I feel like im not receiving fair treatment or getting my car's engine replaced.

Turbo and turbo oil return line is defective. Leaks oil and over heats engine. Dealerships admit this is a serious issues that they've seen daily with the sx models but refuse to address it until a recall comes out. Anytime the vehicle is driven, it constantly leaks oil. Whenever it is parked, it leaks oil. It's only from the turbo feed line.
