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.

The forward collision warning system stopped working and the warning lights lit up saying the camera was obstructed, even though it was a clear day, and the car was clean (it had literally just been cleaned). This has happened previously at random times.

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 2020 Kia Forte Koup verdict →
