Oct 28, 2024Transmission & drivetrain

While driving on interstate 81 my transmission went out while going up a hill. I was almost rear ended by the driver behind me and while trying to get into the right lane I almost side swiped someone. This is the third time something has gone out on this car while I was driving. First the engine went out and when I contacted Kia and told them that my engine went out because of the same problem that their other cars have, they told me that there was nothing they could do. So I replaced it with my own money. A few months later the transmission goes while I'm driving. Almost causing an accident once again. Because Kia told me there was nothing they could do with my engine, I didn't even bother to call about the transmission. Once again, I replaced it with my own money. Now the same problem with the transmission has happened again and I can't put another transmission in this car. I still owe $8,500 on my loan and my car is basically a paper weight. I have made a complaint to you guys every time and nothing is being done about this. Every other Kia Forte's engine has been recalled except for mine. Something is going on with Kia cars and parts and it's leaving people in a really crappy position. I owe money on a car that I cannot drive. All because I bought a Kia. This situation is getting absolutely ridiculous. Someone needs to do something about this. It's not right that a company can have such an unreliable car and leave people in these types of situations. I have no other options here. There's nothing I can do. I hope you are the right organization to contact about this. I am done putting money into a car that is a death trap and a hazard to drive. If I do end up fixing the transmission and this happens again, I'm worried that the outcome is going to be worse. I've almost been in two accidents because of this faulty equipment. Hopefully someone does something before there's a third.

The engine lost pressure while being driven on the interstate. My daughter was able to pull over and then the car began to smoke. She and a passenger immediately exited the vehicle. The vehicle was towed to the nearest shop and was diagnosed with engine failure. My daughter indicated that no check engine light illuminated nor did the temperature gauge note that the vehicle was overheating, but it just began to lose pressure even when she tried to accelerate. I was researching cost to have the engine replaced and came across other Forte owner's testimony that they have had engine problems as well, but the Forte was not listed under the Kia recall for engine issues. But perhaps, it should be.

Jun 29, 2024Engine

I have already filled out one of these forms a couple of years ago. It is absolutely ridiculous that every 2011-2015 Kia Forte engine has been recalled, but mine has not. My engine completely blew up a few years ago. It has the exact same problem all these other engines have. I called Kia and asked them to help me replace it bc the issue is exactly the same and they refused. A con-rod warped and then broke and it shot through the bottom of my engine. The rod could have shot back into the inside of the car. God forbid my daughter would be in my car and that happens. I had to replace the engine and the turbo which isn’t cheap at all. Then because of the strain of all of that, it made my transmission go out which has now been replaced. All of these other engines have the exact same problem. It’s the same problem as the 2.0L, but I guess because mine is a 1.6L and it’s a manual transmission, mine hasn’t been recalled yet? The only reason I’m making another report is because my check engine light is on, AGAIN, and the new engine in my car is starting to experience the exact same issues as my last one. Literally every other type of Kia Forte engine has been recalled except for my. I would like a recalled to be issued and a refund of the money I have sunk into this car. I can’t sell it because I owe too much on it, so the only option is to fix it. At this point I have put more than double the amount of money into this car than it’s even worth. Something needs to be done here. I’m really not trying to wait around until it blows up again and I have to replace another engine. I know I’m just one person, but there has to be other complaints like this.

On approximately, 04/15/2024, 8:00 am, My 2015 Kia Forte with less 115,000 miles suddenly shut down going 65 MPH! A severe accident was avoided by manhandling the steering wheel to get it to the side of the road. When I called the Kia's Consumer Affair, to report the incident, I was told there was no recall on the motor so they were not labile. I am very frustrated, upset and stressed that Kia's doesn't care about it reputation.

Purchased the car certified preowned from a Kia dealer with 45,000 miles on it, meaning I would have the the remaining 55,000 miles of the 100,000 mile powertrain coverage. At 77,000 miles a small ticking noise started on the way to work and became a knock on the way home. I pulled over where it was safe and towed it to the dealer. They replaced the engine under warranty. Now at 154,000 everything has been running great except for burning oil rather quickly. Where I get my oil changes done offers free top-offs so I would return frequently to make certain the oil level was always in the safe zone. Driving home from work one night, I was on a busy freeway when suddenly and without warning a small squeak noise came from the engine and it stalled. Luckily I just happened to be in the right lane and there happened to be a narrow but safe shoulder to coast over to. Had this happened while I was close to the fast lane, the consequences could’ve been dire. The engine would not hardly turn over and would not start. I had it towed to my mechanic who said it sounds like a serious engine problem and you should contact the dealer. I towed it to the local Kia dealership where the service department informed me that there was an extended 50,000 mile warranty added to the original 100,000 warranty (which I was never notified about) but since I was 4,000 miles over I did not qualify. This means the replacement engine quit after 77,000 miles just like the original. I feel that they should in good faith honor the warranty - had I been informed I could brought the car in just 4,000 miles earlier and they would’ve checked the compression and determined that the rings were failing which is why it used so much oil, and they would’ve replaced this second engine under warranty.

Apr 8, 2024EngineFuel system

Over the last 5 years that I have owned the vehicle, the engine will stall when idle or at low speeds. This has happened at stop lights, on hills and while on the highway (which is obviously very dangerous). The engine the vehicle has to be turned off and restarted and usually it will stall again within a few minutes. For the most part, this happens after the vehicle has been driven for at least 15-20 minutes and there are few issues at higher speeds. As such, when taken to the dealer, they have been unable to replicate the issue. The issue is sometimes resolved after an oil change, however it may recur before the next oil change is due (ie within 3 months). The vehicle has otherwise had it's recommended service Many internet searches note many vehicles of my model and many other Kia's with the exact same issue

When driving it suddenly won't pull a hill. It will slow down to 20-30 mph even on an interstate. I've had it in the shop several time and they can't find anything wrong. It did it again and I took it in and the mechanic told me there was a recall on the computer system but I can't find it. If there's a recall please let me know at [XXX] .

I purchased a 2015 Kia Forte5 car (Pearl White) used but I noticed the paint peeling. It seems to be getting worse because the same spot is getting bigger and now a new spot on the top has appeared. I took the car to a body shop and was told it was a factory paint defect. I went online and saw that Kia and Hyundai had a factory issue with the pearl white paint for several years around my car year model. I was wondering if the paint chipping can be fixed or me compensated for the repairs. The damage is on the rear hatch and passenger side top of car next to sunroof. One is about a quarter size and the other a little smaller than a dime. Thanks in advance, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2015 Kia Forte Koup verdict →
