Took my Kia Forte in to the auto repair shop because the engine started making a knocking noise. I have the oil changed regularly just as it is supposed to be done, and just had it changed less than 2 weeks ago. The shop said the engine has major engine failure and that there was nothing I can do about it. They said I will have to replace the engine. I called the Kia dealership to find out about the recalls on Kia motors and they said that my engine is not on the recall list but that there are many of the same motors that are failing and I would have to call Kia Consumer Affairs to find out if maybe they will add my engine. I see nothing but where other Kia owners are having the same issue with both the 2L & 2.4L engine and Kia is being nasty about replacing them. I am very upset as my car is not part of their recall and know that it should be.

Ive been experiencing what other people on Kia forums has labeled as hard shifting since November of 2017. When I start driving the car jerks really hard in between 1-2 RPM or when it's shifting. It's not the transmission fluid and it may be the heat temp sensor but I don't know.

Forte

  • 105,000 miles
Hello, I am currently having issues with my 2010 Kia Forte. The vehicle has been struggling to accelerate and soon eventually began to feel as if it were going to stall out all together every time I stepped on the gas. The check engine light came on and after diagnosing the code, it read P0336 (crankshaft position sensor a circuit range/performance). After some research I found that apparently there is a recall on these engines for what appears to be the same issue I am currently having. I looked up my vehicles VIN on this website and was notified that there is not currently an open recall even though I had just read that hundreds of thousands of vehicles of the same make and engine type (theta 2) were being recalled for crankshaft issues. Would like to have my car checked out via recall measures. The safety of my family is in question due to these known issues.

As I was exiting the highway I heard a rattling noise coming from under my hood. Then all of a sudden smoke start to come fro M under hood and out the back of the car. As that was happening I heard a loud bang then my engine shut off before I could pull over. After I was towed to a local dealership and after my car went through a diagnostic check I was told by the mechanic that my engine failed even though it was in great condition and we'll maintained.

At a stop light or stop sign. It will quit for no reason. I have to put it in park or neutral to start and continue. Plus, driving along the transmission will kick out gear for a second and then go again.

I have a 2010 Kia Forte koup. It runs and drives alright besides it makes such a knock. I have heard it could be a rod knock or a spud bearing etc. Need to kno if I'm under manufacturer warrenty as I'm not the original owner. Car only has 88,000 miles on it too. Also the place I took it to see what was wrong said it would be 2 grand to fix it. How do you expect me to do that as I'm making payments on the car and only had it since April of this year.

I have Kia Forte which was running fine. Until I change the starter then the oil was pumping to the engine it would knock loudly & if I would any longer it would blow the engine.

Forte 4-cyl

  • 10 miles
When at stopped position I step on footfeed and rpms do not increase and then all of a sudden the vehicle surges forward. The rpms as shown on the gauge show that it is in the idle state until the sudden surge. This mostly happens when trying to advance slowly. This happens infrequently but presents a safety concern when it happens in close facility or when in traffic. The delay in vehicle movement may be as long as 10 seconds and then it just jumps to current demand from the footfeed. This happens rarely but when it happens it really alarms the driver.

The contact owns a 2010 Kia Forte. The contact stated that while driving 40 mph, the engine stalled. The contact was able to restart the vehicle but the problem recurred several times. The vehicle was taken to the dealer, who could not duplicate the failure. The vehicle had not been repaired. The manufacturer was not made aware of the problem. The approximate failure mileage was 43,000.

I was driving through a reduced speed zone of 35 mph and went to set my cruise control, about 3-5 seconds later I felt the car go dead. I lost power steering and all electrical systems. My indicator lights were on and flickering and I had no control over the vehicle other than waning off to the side of the road to get out of the way of traffic. Once my car came to a stop I proceeded to turn off the ignition. I tried starting it and the engine turned a couple of times but went dead so I turned it off. I tried one more time to start the ignition and was only barely able to get the engine to start and maintain. I went off on my way and later on my way home I stopped to get food and when I got back in my car I tried starting it and it struggled to start. I have only had my car for 1.5 years and only in the past couple months experienced problems with my cruise control not activating and setting to my current speed.

Our 2010 Kia Forte ex lost 90% of power repeatedly (rpms drop to idle, regardless of throttle position) at speeds from 0-35mph. This is not the first occurrence, but I think it is the same problem. This is very dangerous if you are making a left turn and you lose acceleration, you can be in the way of oncoming traffic by losing power. About 2 years ago (25,000 miles or so) the tps (throttle position sensor) went out. Kia could not diagnose it until it threw a code (lame). Now we get the same issue, the vehicle is stalling, or "stumbling" when the speed should be constant or accelerating, but there is no engine code for the code reader to pickup yet, so the mechanics can't figure out what to do. Apparently this is a problem on many models of Kia/Hyundai and the mechanics don't recognize it so they can't fix it, and you are stuck with a dangerous condition. I think there should be a recall of these faulty tps sensors. Kia/Hyundai should at least issue a safety tsb (technical service bulletin) to clue in their mechanics as to what the problem is. Here's a great article showing the problem: www.Kia-forums.com/Kia-carnival-sedona-2006/80251-tps-sensor-symptoms-tps-failure-cel.html thanks for your attention to this matter.
