My Engine died at 114,000 miles. It developed engine knock. I now have to replace the engine. Kia refuses to help with this and is asking for 8,000 to replace the engine.

Unknown, 2010 Kia Forte engines have an active and open recall in Canada for a ticking noise that leads to vehicle fires and cause death it is not being addressed here in the United States even though the problems are exactly the same there's a smell of gas burning there are ticking and knocking noises coming from an engine and Kia is refusing to replace it here in the United States but they are actively replacing it in Canada

Very loud knocking noise coming from engine. No check engine light or oil light has come on at all. It's been doing this for over a year now.. Ive taken it to several place and no one can figure it out. The knocking gets so bad it makes my steering wheel shake.

hi, i have a standing issue with my 2010 kia forte sx 2.4l the engine developed this knock that has totally incapacitated the car so it cannot be driven. every mechanic ive been to says that the engine is done and needs to be replaced. ive checked for recalls and i found hundreds of consumers with the same exact problem where these 2.4l engines developed a crippling knock. Has this establishment recieved any complaints and if so what is being done to relieve the consumer who has no where to turn and is stuck with a car they cant use and is being ignored by KIA COORPORATION and every one else. Any suggestions would be greatly appreciated, Thank You

Engine is knocking very loudly. Concerned it is going to fail while driving it and cause an accident. I have noticed many other people have this issue with this 2.0 engine Kia has.

While the vehicle was operating the engine had a noticeable amount of power reduction and there were multiple knocking sounds occurring simultaneously. The vehicle was being operated in the right-most furthest lane of a busy freeway in the middle of traffic and at freeway speeds of approximately 65 mph. The issue seemed to originate from the engine causing engine malfunction without engine light indication. There was no engine light prior, during, or post-incident. The vehicle has been professionally inspected, but not thoroughly diagnosed. Altogether, the motor has had a major unidentifiable malfunction and now I have no transportation from the once-reliable vehicle I was using.

Randomly the car refused to accelerate, rpms would not go past 3k. It happened it different time points of a drive. There was never any check engine light. Mechanic drove the vehicle and ran a check on it and said with out a warning light there isn-€™t much I can do. Suggested replace crank shaft sensor. There was no change to the point the entire car died while driving up hill with no shoulder and a very large truck behind. My children would be dead right now if there had been another vehicle in the lane next to me I was able to barely to get the cat into. The car started back up after 30 mins. Was looked at again, informed it could have something to do with the engine tick, still no warning lights. The car stalls, jerks like a misfire and had refused to keep a stable speed while on the interstate

Vehicle has been knocking since the day I took the vehicle over. Was told that Kia always said its normal but its clear that it is a rod knock and that thada engines had this problem. Im afraid if the rod lets loose it could cause a fire.

My Kia was jus fine driving down to my daughters house which is an hour N half where I live. Where all of a sudden engine light came on and a knocking sound came on slight noise. I kept an eye on the noise and vehicle. When we stopped I checked all the liquids and everything was fine. We had to take care of some things then on our way home it was sounding horrible and all of a sudden the check engine light was on, oil light and battery light. So I pulled over and called to have my car towed home. I did not want to risk anything worse, but honestly I think it is the worse for absolutely no reason for when there is no leaks and all fluids are full.

Just after purchasing the car used with 73,349 miles on the odometer on 7/31/2014 there was a slight knock in the engine, which sounds like the problem that led to recalls on later years models with 4 cylinder engines, so I think the problem started earlier. Since there was no warranty (sold as is) on a used car the dealer told us repairs would cost more than just replacing the engine, so I had to pay $3,000 to replace the engine. I complained to both the dealer (fairfax Kia) and the manufacturer with no resolution.

The car has less than 88,000 miles on it. The car started making ticking noise. The repair shop said it is the engine and it needs replaced. They also said this was a very common issue on these engines. Said it wasn't worth the cost to replace. I'm so angry cause the car still should have alot of life left in it. The car has been taken care of and this is a faulty because of Kia!!

My car was bought brand new from Kia of clarksville. It has always had a tick I was told it was normal. At 88,000 miles my car locked up. Just driving up a small hill it started knocking loud and lost power. Took it to Kia they want $6000 to repair it with a junk yard motor. How do they sell faulty engines and get away with it. I took good care of my car and oil changes when due. I'm so upset that as a consumer we have no protection against this.

This engine has a widespread problem of ticking coming from the top part of the engine, and issues with oil including burning oil. I personally have experienced both despite many efforts to try to remedy the problem. Many other drivers of the same car have had these same issues which have led to scoring in the cylinders and complete engine failure. I myself am also very close to engine failure. Many people including myself believe that there is an underlying issue(s) causing these problems in the theta II engines. Many people in Canada have had their engine replaced for the same problems.
