2020 Kia Forte problems

“During a day trip on 9/19/26 my 2020 Kia Forte (purchased new and well maintained) lost power and several of the dash board lights came on including check engine, traction/stability control, and collision alerts. The car entered what I was told is "limp mode". I had the car towed home and after one shop misdiagnosed the problem I had it towed to the Kia dealership where purchased. I was told the engine had code p0017. I was sent a document that the "phaser sheared off p0017 exhaust cam and cvvd gear timing off-recommend long block-cvvd replacement may still have engine damaged after replacement" with a price of $9053.39 attached. Kia service manager is supposed to be seeing about assistance for repair as it is cost prohibitive and I have proof of proper maintenance however I am not receiving info on process unless I reach out. Car has been in Kia possession since 9/24/26.”

“I experienced a check engine light and had the vehicle diagnosed with codes P0017 and P0014. The vehicle was taken to a Kia dealership, where the technician found that the exhaust camshaft was free-spinning without the phaser and that the pin connecting the two had sheared. The dealership replaced the exhaust camshaft and phaser and released the vehicle as repaired and operating normally. Less than 24 hours after pickup, the check engine light returned during normal driving. While returning the vehicle to the dealership as instructed, the engine lost oil pressure and stalled three times. One stall occurred after exiting the highway and left the vehicle disabled in a high-traffic intersection, creating a serious safety hazard. The vehicle was returned to the Kia dealership and remains available for inspection. Subsequent examination reportedly found metal debris in the engine/oil pan and a possible restriction of engine oil flow. The exact cause of the sudden oil-pressure loss has not yet been definitively explained. The failure occurred immediately following a dealership repair involving a physically sheared internal engine component.”

“The crankshaft position sensor keeps going bad and it make the forward collision trigger and it loses power and the dash stops working and causes the car to shut off”

“2020 Kia Forte, 2.0L 14F engine, 109,000 miles: On July 3.2026 "check engine" light came on. Drove to local auto parts store to have code downloaded, P0017 cam position sensor. Car was performing fine, except for engine light. Drove car to Kia dealership. While driving, warning light for "front collision system came on and car began performing erratically. Left car at dealership for diagnostics. Yesterday received call from dealer, stating that engine needed total replacement due to "lack of oil". Quoted repair cost estimated at approximately $8,000. Car has been regularly serviced, including oil and filter changes per handbook. I have all records for the services. The were no indications of low oil pressure or engine overheating, no warning lights, all gauge readings displayed normal ranges. This same car had a failed transmission replaced approximately 2 years ago, which was covered by an extended warranty related to a recall. There have been 2 engine failure recalls as a result of 2 class action lawsuits for Kia cars with this same engine failure up through the 2019 model years, providing new engines and/or extended warrantees, however, this does not…”

“The contact owns a 2020 Kia Forte. The contact stated that while driving at an undisclosed speed, the air bags warning light illuminated and then went off. The contact stated that while attempting to start the vehicle, the air bag warning light was again illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact referenced an unknown recall; however, the VIN was not associated with a recall related to the failure. The manufacturer was made aware of the failure but provided no assistance. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 109,900.”

“There are significant idle issues (rpm’s shoot up & drop down irregularly while in park) and the car shut off while in park following irregular rpm movement, but was not exhibiting this behavior while previously parked elsewhere. I sent it in to be checked but nothing could be reproduced. A few weeks later the car began doing what felt like engine braking (in a manual vehicle) while I was letting the car roll forward in a traffic jam (foot off of pedals for short moment). A friend witnessed a the rpm’s rising and falling dramatically while sitting in the parked car. Later the car began shutting off at low speeds while my foot was on the gas pedal. All of the lights on the dash appeared to be on and the car wouldn’t crank again until the 2nd attempt and only stayed on when pushing the gas pedal. I sent it back again but it could not be reproduced so nothing was done. A few days ago I noticed it was idling weird again(Up and down dramatically). Today when pulling into my neighborhood my car began to accelerate on its own. - I pushed the gas lightly to make the turn from a stop and took my foot off of both pedals in a slow transition to the brake. While my foot…”
