Owners of certain Hyundai and Kia models equipped with Theta engines have faced engine seizures and failures severe enough to trigger a class-action settlement, while federal regulators have taken enforcement action against companies selling service contracts marketed to drivers already frustrated by repeat shop visits. The pattern cuts across brands: engines that stall, transmissions that slip, and infotainment screens that freeze, all generating repair bills that stack up fast. J.D. Power’s 2025 U.S. Vehicle Dependability Study and federal complaint records together paint a picture of specific models whose owners spend more time and money at the service counter than they expected when they signed the purchase agreement.
Repeat repair costs and why they hit owners harder in 2025
The financial sting of owning a trouble-prone vehicle goes beyond a single breakdown. When the same car returns to the shop three or four times in a year for unrelated faults, each visit carries its own diagnostic fee, parts markup, and lost work hours. The 2025 dependability report published by J.D. Power tracks problems per 100 vehicles across the industry and has consistently flagged infotainment and electronic system glitches as a growing source of owner complaints. Those glitches rarely trigger safety recalls, so manufacturers are not obligated to fix them for free once the factory warranty expires.
That gap between what breaks and what the warranty covers is where the nickel-and-dime effect takes hold. A driver whose touchscreen reboots mid-navigation or whose backup camera blacks out intermittently faces a choice: pay out of pocket, buy a third-party service contract, or live with the problem. The National Highway Traffic Safety Administration maintains public complaint data that log owner-submitted issues by make, model, and year, giving researchers a way to quantify how often specific vehicles generate non-safety grievances that still cost real money to address.
Hyundai and Kia owners with Theta II engines faced a far more expensive version of this cycle. Engine failures in those vehicles were not minor electronic annoyances but catastrophic mechanical events. Hyundai Motor America and Kia America resolved the resulting class-action litigation, and the official settlement portal for In re Hyundai and Kia Engine Litigation outlines the vehicles covered, the free inspections available, and the extended warranty terms offered to affected owners. A company newsroom release confirmed the settlement scope and stated that eligible owners could receive free engine inspection and, where necessary, repair or replacement under extended warranty coverage.
Federal enforcement, service contracts, and the repair-cost trap
Drivers worn down by repeated breakdowns often turn to aftermarket service contracts promising to cover future repairs. Federal regulators have found that some of those contracts are sold through deceptive practices. The Federal Trade Commission maintains an enforcement case page concerning American Vehicle Protection Corporation, which the agency alleged used misleading marketing to sell extended auto warranty programs. That case record, accessible through the FTC’s American Vehicle Protection file, illustrates how the frustration of constant repairs can push owners toward products that do not deliver the protection they expect.
The FTC’s consumer guidance on auto service coverage draws a clear line between a manufacturer’s warranty and a paid service contract. A warranty is included in the vehicle’s purchase price and obligates the manufacturer to repair covered defects. A service contract, by contrast, is a separate purchase with its own exclusions, deductibles, and claim-authorization process. Owners who confuse the two can end up paying for coverage that duplicates protections they already have or, worse, excludes the exact repairs they need most.
The practical risk is straightforward. An owner whose vehicle has a known defect pattern, such as the Theta engine issues documented in the Hyundai and Kia litigation, may buy a service contract thinking it will cover future engine work. But if the manufacturer has already extended warranty coverage for that specific defect through a settlement, the service contract adds cost without adding protection. Conversely, if the owner’s problem falls outside the settlement’s scope, the service contract may still deny the claim based on its own exclusion language. In either scenario, the driver may continue paying monthly premiums while still facing large, unexpected repair bills when the car fails.
Unresolved gaps in repair data and owner recourse
Several questions remain open for owners trying to figure out whether their vehicle belongs on a “constant repairs” list. NHTSA’s complaint database captures what drivers report, but those submissions are self-selected and unverified. A high complaint count for a given model signals frustration, not a confirmed defect rate. J.D. Power’s dependability study uses survey methodology that measures owner-reported problems, not repair invoices. Neither source tracks actual out-of-pocket spending per vehicle over time, which is the number that matters most to someone budgeting for car ownership.
The Hyundai and Kia engine settlement offers concrete relief, but its boundaries are specific. Owners whose vehicles fall outside the covered model years or engine types receive nothing from the settlement, even if they experience similar symptoms. Others may have sold or traded in their cars before the settlement period and therefore miss out on reimbursement for past repairs. That leaves a sizable group of drivers with vehicles that share design DNA or failure patterns but lack the formal recognition that would unlock extended coverage.
For those owners, the primary recourse remains a patchwork of individual warranty claims, goodwill repairs, and, in some cases, small-claims or state court actions. Some may file complaints with NHTSA in hopes that a growing pattern will trigger a defect investigation. Others may organize or join new lawsuits, arguing that their engines, transmissions, or electronic systems suffer from the same underlying flaws already acknowledged in related models. These efforts can take years to resolve, during which time the cars continue to age and depreciate while repair costs climb.
The lack of comprehensive repair-cost data also complicates policy discussions. Without clear numbers on how much owners of specific models spend on unscheduled repairs over a decade, regulators and lawmakers have limited visibility into which vehicles impose the heaviest financial burdens. Insurers and lenders, by contrast, may have better insight into those costs through claims and repossession data, but that information is rarely shared publicly in a way that helps consumers make informed choices.
In the meantime, individual owners can take a few practical steps to avoid the worst of the repair-cost trap. Checking NHTSA complaints and dependability scores before buying a used vehicle can help flag models with a history of chronic issues. Reading the fine print on any proposed service contract-and comparing it against existing manufacturer warranties or settlement-based extensions-can prevent redundant or misleading coverage. And keeping detailed records of all repairs, including dates, mileage, and invoices, can strengthen later claims for reimbursement if a defect is eventually recognized through a recall or settlement.
Ultimately, the stories behind the Theta engine failures, the rise in electronic glitches, and the FTC’s enforcement actions all point in the same direction: the modern car ownership experience is as much about navigating paperwork and protections as it is about driving. Until repair-cost data become more transparent and coverage terms more straightforward, owners of trouble-prone models will continue to shoulder not just the mechanical risks of their vehicles, but the financial and legal uncertainty that comes with every return trip to the service bay.
