What owners reported
Issue summaries by Kia Forte model year
POWER TRAIN
Owners report that the 2019 KIA Forte frequently experiences transmission failures, often leading to a complete loss of power while driving. Typical symptoms include difficulty accelerating, the transmission getting stuck in gear, and high engine RPMs without corresponding vehicle speed, sometimes forcing drivers to use manual or sport modes to maintain control. These issues commonly occur at mileage as low as 17,500 miles, with some owners experiencing failures shortly after purchase. Safety implications are significant, as multiple reports describe incidents where the car loses power on highways, creating dangerous situations due to sudden deceleration and the risk of being rear-ended. Potential buyers should be aware of these recurring transmission issues and the associated safety risks.
ENGINE
Owners report that the 2018 KIA Forte frequently experiences engine failures, often without prior warning lights or indicators. Common symptoms include sudden loss of power, stalling, engine seizing, and unusual noises such as knocking or shuddering. These issues are often observed in vehicles with mileage ranging from approximately 74,000 to 163,000 miles. Safety implications are significant, as multiple complaints describe instances where the vehicle loses power while driving, creating potential hazards for both the driver and surrounding traffic. Prospective buyers should be aware of these reported issues and the potential need for engine replacement.
Severity signals: 1 crash, 0 fire, 0 injury reports
UNKNOWN OR OTHER
Owners report several recurring issues with the 2020 Kia Forte. A significant number of complaints highlight theft vulnerability, with multiple owners describing ease of vehicle theft due to inadequate security features, even after software updates. Additionally, issues with the multimedia screen are frequently mentioned, with owners noting delamination and failure beyond the warranty period, typically around 28,000 miles. Safety concerns are evident, with reports of brake system failures and one incident involving a vehicle fire after brake performance deteriorated while driving. Complaints also include malfunctioning trunk latches and electronic issues, such as dashboard screen bubbling and separation. These issues pose potential safety risks and could result in costly repairs for used car buyers.
Severity signals: 3 crash, 1 fire, 0 injury reports
UNKNOWN OR OTHER
Owners report several issues with the 2018 KIA Forte, most notably involving engine performance and electrical components. Common symptoms include the vehicle stalling while driving or at a stop, difficulty with starting, and persistent engine warning lights, often linked to oil pressure problems. Some owners mention these issues occurring shortly after engine replacements or repairs, and one report includes a crash with injuries and airbag deployment. Electrical problems are also noted, such as malfunctioning key fobs and doors locking unexpectedly, sometimes while the car is running. Additionally, two separate complaints describe fires, one resulting in significant property damage. These issues are reported across various mileages, with some incidents occurring soon after purchase, indicating potential safety concerns for prospective buyers.
Severity signals: 1 crash, 2 fire, 1 injury reports
ENGINE
Owners of the 2019 Kia Forte frequently report engine failures, often without warning. Common symptoms include stalling, loss of power, and engine seizure, with several complaints noting the absence of dashboard warning lights prior to failure. These issues are reported across a range of mileages, from as low as 8,000 miles to over 120,000 miles. Two complaints involve fires, one linked to an oil pan issue, raising safety implications. Buyers should be aware that some owners mention significant repair costs and limited warranty coverage, particularly for subsequent owners.
Severity signals: 0 crash, 2 fire, 0 injury reports
ELECTRICAL SYSTEM
Owners report several electrical system issues with the 2019 KIA Forte, including problems with the headlights, brake lights, and various dashboard warning lights. Complaints frequently mention headlights and brake lights failing intermittently, with some cases involving melted wiring harnesses. Multiple owners describe the car shutting off unexpectedly while driving, and some report difficulty starting the vehicle. Safety implications are evident, with three complaints involving crashes and two involving fires. These issues often appear around 50,000 to 100,000 miles, though some occur earlier. Potential buyers should be aware of these electrical concerns, as they may affect both safety and reliability.
Severity signals: 3 crash, 2 fire, 1 injury reports
UNKNOWN OR OTHER
Owners of the 2019 KIA Forte frequently report issues with the vehicle's forward collision warning and automatic emergency braking systems, with multiple complaints indicating false activations or warnings of obstruction despite no visible impediments. Several complaints mention engine problems, such as sudden shutdowns while driving, excessive oil consumption, and related failures, often occurring around or after 90,000 miles. Transmission issues, including a failure to accelerate and transmission fluid pressure warnings, are also noted, with some reports of these problems leading to the need for major repairs. Safety implications are evident, with two reported crashes—one involving an injury—linked to these issues, highlighting potential risks for loss of control. Buyers should be aware of these recurring problems and the potential for significant repair costs post-warranty.
Severity signals: 2 crash, 0 fire, 1 injury reports
ELECTRICAL SYSTEM
Owners of the 2018 KIA Forte frequently report issues with the electrical system, including flickering dashboard lights and malfunctioning speedometers. Several complaints mention problems with battery terminals, leading to stalling and the inability to restart the vehicle, particularly around 120,000 miles. Some owners describe the car unexpectedly switching between ECO and Sport modes, causing changes in vehicle performance without user input. A significant safety concern arises from a reported fire originating in the engine compartment while driving, and another issue involves theft vulnerability due to a lack of an immobilizer, leading to increased theft incidents. These patterns suggest potential reliability challenges for prospective buyers, especially concerning electrical malfunctions and safety risks.

How to interpret the counts
Complaint totals are not failure rates
A popular or older model can accumulate more complaints simply because more vehicles exist and have spent longer on the road. The categories above aggregate the counts embedded in each model year's leading issues. Use recurrence across years and severity signals to decide what to inspect; use the VIN and a mechanical inspection to judge one car.
Source trail
Where this Kia Forte data comes from
VinExposed combines model-level research with the vehicle-specific history you get from a VIN. Reliability scores and complaint patterns come from Auto Reliability Index's Kia Forte research, which analyzes NHTSA records and independent repair data.
Recall counts describe a model year, not the repair status of one car. Confirm the exact VIN with the official NHTSA recall lookup and a vehicle-history report before buying.
