Are Kia and Hyundai Engines Secretly Plotting to Quit on You? In recent years, Kia and Hyundai have faced growing challenges related to engine reliability, affecting both gasoline-powered and electric vehicles. What began as scattered complaints from owners has evolved into large-scale recalls, legal disputes, and growing concern among vehicle buyers and mechanics alike. We are covering WHAT THE KIA IS HYUNDAING TO THEIR ENGINES, as of today, July 29, 2025, yes a play on words, but come on now! WHAT IS REALLY GOING ON?
As far back as 2023, Kia and Hyundai began recalling millions of vehicles due to potential engine fires and mechanical failures. Many of the affected vehicles had engine designs that were prone to premature bearing wear or piston ring issues. In some cases, the damage led to stalling or complete engine seizure. More seriously, some engines leaked fluids that could catch fire under high temperatures. These problems have lingered into 2025 with continued reports and additional recalls.
A specific concern that has resurfaced in 2025 involves certain Kia Soul and Seltos models from 2021 to 2023. These vehicles, equipped with 2.0-liter MPI engines, were found to have improperly manufactured piston oil rings. When these rings fail, engines can burn excessive amounts of oil, leading to overheating, loss of power, and potential fires. Kia has responded by launching a recall that includes engine inspections, free replacements if needed, and a software update designed to monitor internal engine noise that signals ring failure.
This is not an isolated case. Many earlier Hyundai and Kia models equipped with their Theta II engine design have long been plagued by internal wear that can lead to catastrophic damage. The issue was particularly common in vehicles from model years 2010 to 2015. Owners reported knocking sounds, reduced power, or sudden shutdowns. For those models, several waves of recalls and warranty extensions have been implemented over the years, though some repairs remain pending due to high demand and parts delays.
Problems aren’t limited to combustion engines. Hyundai and Kia's newer electric models have also had growing pains. Several battery electric models were recalled due to charging control issues that could cause vehicles to lose power unexpectedly while driving. In these cases, internal circuits regulating the auxiliary power supply malfunctioned, disabling key systems including propulsion. Updates and part replacements were issued, but the incidents raised concerns about quality control in emerging EV technologies.
Safety systems have also drawn attention. Kia recently recalled thousands of hybrid and electric crossover models due to incorrectly routed wiring beneath the passenger seat, which could interfere with airbag deployment. Although not an engine issue, the fix reinforced worries about broader assembly and design lapses across both brands. Even some of the newest vehicles have not escaped scrutiny. A small batch of 2025 Hyundai SUVs was recently flagged for a defect in the electric oil pump control unit that could overheat and spark under the right conditions. This prompted another fire-risk recall, albeit affecting a more limited number of vehicles.
We described the situation plainly earlier in April 2024: “Many consumers are shocked to find their vehicles with major engine failures well before 100,000 miles. We’re now regularly seeing customers trying to sell us cars with seized engines, blown piston rings, or electrical problems that make the car undriveable.” *Full Article Here*
That trend has only grown. A significant number of owners, frustrated by delayed repairs or denied warranty claims, have begun selling off their vehicles to wholesalers or private buyers at a loss. Some owners qualify for extended coverage or settlements, but deadlines and documentation requirements have left others out.
If you own a Hyundai or Kia made between 2010 and 2023, it's a good idea to confirm whether your vehicle is part of any recalls or extended service campaigns. Unusual oil consumption, engine ticking, dashboard warning lights, or sudden loss of power are all signs that should be taken seriously. For those with affected EV models, check whether key electronic modules have been replaced and updated.
In summary, the engine troubles with Kia and Hyundai aren’t just a past problem, they continue to affect both legacy and modern models across gas and electric platforms. While the companies have taken steps to address these issues, the number of affected vehicles and the complexity of needed repairs mean many owners are still in limbo. Staying informed, acting quickly on recalls, and maintaining detailed service records will help consumers protect their vehicles, their safety, as the situation continues to unfold.
