The contact owns a 2018 Kia Forte. The contact stated while driving at an undisclosed speed, the vehicle failed to accelerate as needed. There was no warning light illuminated. The vehicle was taken to the dealer, and it was discovered that the engine oil level was extremely low. The dealer kept the vehicle for nine months and performed an oil change. The failure persisted. The vehicle was taken back to the dealer, who replaced the oil gasket cover, but the failure recurred with the engine making knocking sounds. The vehicle was taken back to the dealer and determined that the engine had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 104,000.

NHTSA ID 11726619 · filed Mar 24, 2026

Recently, while my boyfriend was driving my vehicle, the engine suddenly lost power without warning. He had the accelerator pedal fully depressed, yet the vehicle would barely move. He was fortunate to safely maneuver the vehicle off the road. Upon inspection, he discovered there was no oil present in the engine. Critically, neither the low oil warning light nor the check engine light had illuminated prior to this failure, providing absolutely no warning of a severe mechanical problem. After adding oil and performing a proper oil change, the engine began violently shuddering and shaking upon startup, and only then did the check engine light illuminate. The vehicle was immediately towed to an authorized Kia dealership, where I was informed that the timing chain had failed.

The engine went out in the middle of a busy highway road leading to a dangerous situation that I almost lost my life the vehicle was purchased in 2021. There shouldn’t be no reason that the engine should have went out that quickly when maintenance was kept up not only that there was an airbag defected issue, which is a safety hazard as well. It was the most scariest situation ever when the engine shut off in the middle of the road. Also, there was many concerns of my vehicle being reported of also being almost stolen by Kia boys I have a report on that.

The switch needed to be replaced by kia in prescott valley because it was a recall, they replaced my switch, and a few weeks later now my airbag light is on and they no longer work, and they won't take care of it, the lady proceeded to tell me they didn't replace the switch when I have the proof that they did indeed do it, and now my airbags no longer work, if I get into an accident because they messed it up and my airbags no longer work I will have a lawsuit against them for not wanting to take care of a recall they couldn't do right in the first place.

2018 Kia Forte, purchased certified used June 2022, will randomly go into ECO or Sport mode on startup or while the vehicle is in motion. Vehicle is not equipped with Drive Mode control buttons, indicating that ECO/Sport modes are not supposed to be active feature. While I vaguely remember the mode change occurring during previous two years of my ownership, the first noticeable incident in 2024 was of the vehicle going into ECO mode (green indicator light) happen upon startup the morning of 5/26/24. This was noticeable due to the fact that the ECO mode slow down caused me to nearly be rear-ended by a semi while merging onto the freeway. The vehicle remained stuck in ECO mode for several weeks. On the morning of 6/10/24, while driving, vehicle began to sputter/hesitate and ECO light blinked on/off then switched to Sport (yellow indicator light) mode and vehicle surged forward. Vehicle then switched back to ECO mode and it remained in this mode until the morning of 6/13/24, at which point it went into Sport mode upon startup. It went back into Normal mode (no indicator light) upon startup the evening of 6/13/24. Vehicle was inspective by selling dealership 6/15/24 and they could not duplicate the issue nor pull trouble codes. Remained in Normal mode until the evening of 7/15/24, at which point it switched back to ECO mode. Dealership has been notified. It should be known that ECO mode slows down the vehicle response to conserve fuel, Sport mode speeds it up. While these features can be useful when wanted and properly installed with the appropriate controls, the randomness in which these features engage make them a safety hazard, especially considering the control buttons are not installed. Based on NHTSA VIN information the trim package of my vehicle, LX (which KIA America has yet to confirm even though I have made multiple inquiries), Drive mode is an optional feature which was not activated by the original/first owner.

While driving the car with the flow of busy traffic, the engine failed and the car stopped. It eventually turn back on (side of the road) but now drives with hesitation, a strange noise, and with the engine light on. This cycle continued until we arrived at the repair shop. And after much research, it seems that this experience is common for other Kia engines. Why was mine not included? Someone could have been badly injured!

The contact called the local dealer, where an appointment was scheduled; however, the vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 143,000.

Part of the subframe is corroded already and the engine cradle has begun to break, the control arm has begun to move where it meets the engine cradle and I now need to have the vehicle repaired. Previously the lower engine mount fell out of place due to the threads that kept it attached to the subframe were worn out due to corrosion and was causing the vehicle to vibrate violently. This issue has been fixed for $400 but now the rest of the engine cradle has to be inspected and repaired due to the corrosion. I have to make an appointment with the KIA repair center in my area to have the vehicle inspected which will be weeks if not months out to have it looked at as they are often booked. I'm at my wits end with this car as it's been constant issues since buying it 5 months back, with a baby on the way I can't afford repairs and want a resolution that won't break the bank or to warn other drivers of this make and model of the issues that are plagued with it such as the back tail lights having a light assembly seal issue where water is able to enter and damage electrical components. I've uploaded two images regarding the subframe issue, one related to the lower engine mount becoming detached and the other regarding the engine cradle to control arm.

I am the 2nd owner. Mileage currently: 25,562 Mileage when purchased in August, 2020: Approx 15,500 Air Compressor Car was not driven for most of 2020 and stayed in garage (pandemic). Car has only been serviced at Kia. Service in May 2022: Dealer checked off all components, valves, hoses, etc. were fine (option boxes were green, yellow, red, red being needing service soon. They checked "green" for box being discussed. August 2023 Brought car in for 3 recalls. Several weeks prior I noticed that the AC wasn't functioning as well as it used to so I had them check. Coincidentally, warranty expired 2 months earlier in June. Paid for the diagnostics, results are that the air compressor is leaking which will cost $1700 less the $300 that I've paid (estimated). Not sure why this wasn't noticed in May 2022 when warranty may have covered some/all of this repair. The car is barely driven since I am underemployed. Additionally, the compressors should last 8-10 years, not under 5 years or 25,000 miles. Regardless, while AC is always nice on a hot day, have your ever tried to drive your car on a rainy day without a working AC? Try it. I bet your windows fog up really quickly. So yes, it is a safety issue. I've reached out to KIA USA for assistance as a good will gesture to meet me half way (not even asking for free, just to meet me half way). It has been almost 2 weeks and they keep stringing me along. I only have a small window with Kia Ventura to decide if they should finish this work before I lose out on the $300 that I've already paid. It's ridiculous.

With less than 40,000 miles on the car/tires, one of the front tires blew on the highway. Discovered it blew out on the side wall and metal was showing, took the car in and had the tire replaced. We did not keep that tire because we didn't realize it was not an isolated incident. About 2 weeks later the same thing happened to the other front tire. Took the car in to have the other 3 replaced and was informed that one of the rear tires was in the same condition and we are lucky it didn't blow out on us. The car has only been inspected by the tire shop and we kept the tires this time for inspection of anyone that can help file some sort of recall or claim. There is still a good amount of tread on the tires. This could very well have caused serious injury or death to my family!
