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.

My engine is failing due to excessive oil consumption despite having proof of regular oil changes and maintenance. My car has been inspected, and the dealer has stated this is due to a known manufacture defect. My safety and others are at risk because my car stalls when I decrease speed and I cannot accelerate fast enough to get up to the speed limit creating a risk anytime the speed limit changes or when I am using an on ramp to get onto an interstate or highway. Kia dealer has confirmed the issue and is currently working on an estimate for a new engine. The Kia dealer is the manufacturer of my vehicle. The warning sign before this happened was my car stalled a couple times, then the check engine light came on within 10 miles. I then took it in to get looked at where the Kia dealer diagnosed the issue as the known manufacturer defect with the engine burning oil too quickly. These issues first appeared on August 12, 2026. I have attempted to get Kia corporate to assist with repairs through a Goodwill Request due to the safety issues with driving my vehicle in its current condition, to no fault of my own. Kia denied my Goodwill request. That case number is 26467063.

I was driving this car and received a check engine light and lulled over to find an electrical fire had occurred under the hood. I was able to use a fire extinguisher to put out this fire. The car was towed to a Kia dealership near my home for confirmation and an estimate of the damages. It apparently was caused by a problem that Kia has had with the ABS/hydraulic electronic control units that can trigger electrical shorts.

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.

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 applicable to 2020 and newer models, even though it's the same exact same engine model with the exact issue causing the failure. Engine failure in traffic condions can obviously lead to immediate safety issues. I currently have a call into the Kia customer service/complaint department, but no resolution offerred to date.
