The Core Insight
A car journalist shares a cautionary tale regarding his experience leasing a 2024 Hyundai Ioniq 5 and a 2024 Kia EV9. Despite initial enthusiasm for the vehicles' design and performance, both cars suffered from significant, recurring battery-related failures, ranging from 12V battery drains to full traction battery replacements, leading to extended dealership stays and a loss of confidence in the brand's reliability and service network.

Leasing is a strategic hedge: Given the rapid evolution of battery tech and uncertain resale values, leasing protects you from long-term ownership risks.
Dealer infrastructure is the weak link: Even if your vehicle is high-tech, legacy dealership service departments often lack the specialized training required for complex EV repairs.
Reliability isn't just about the battery: Minor electrical gremlins, like 12V battery drains, can be just as disruptive as major traction battery failures.
Regional context matters: If you live in areas with extreme winters and sparse charging infrastructure, a hybrid may still be the more practical choice for your primary vehicle.
I transitioned to automotive journalism in the late 2010s, right as the industry hit a seismic shift. Electric vehicles were moving from eccentric curiosities to mainstream contenders. Simultaneously, Hyundai Motor Group, comprising Hyundai, Kia, and Genesis, began producing some of the most compelling, design-forward, and commercially successful crossovers on the market. As a journalist, I’ve spent years analyzing these trends, but in 2024, I decided to put my own money where my mouth was. For those interested in how global manufacturing shifts are impacting the market, see our analysis on industrial manufacturing trends.
My wife and I were in the market for new vehicles. At my urging, we opted for the "savvy" play: going all-in on Hyundai Motor Group’s electric lineup. I leased a 2024 Hyundai Ioniq 5 SEL AWD, and we took the plunge on a 2024 Kia EV9 GT-Line for my wife. We chose to lease specifically to mitigate the risks of early-production technology and the volatile resale market for EVs. Looking back, that decision was the smartest move I made, though not for the reasons I initially anticipated.
The Practical Verdict
Let’s be honest: the "EV dream" is often sold as a seamless, maintenance-free experience. My experience has been the exact opposite. While I still believe in the potential of electric mobility, the reality of living with these vehicles, specifically regarding dealer support and electrical reliability, has been a sobering lesson. I’ve moved on to a Toyota 4Runner Hybrid, not because I hate EVs, but because my family’s lifestyle in Northern Michigan demands a level of reliability and infrastructure that the current EV ecosystem simply hasn't reached yet. For a comparison on how other manufacturers are approaching the hybrid transition, check out our review of the BYD Song Ultra DM-i.

The Hands-On Experience
My assessment is based on over a year of daily driving and multiple service visits. I’ve tracked every diagnostic code and repair delay. Here is the breakdown of the hardware I’ve been testing:
2024 Kia EV9 GT-Line: Three-row crossover, high-voltage battery system.
Testing Environment: Southeast Michigan, including extreme winter conditions and rural driving.
Service Reality: Multiple dealership visits, reliance on loaner vehicles (including a combustion-powered Kia Niro PHEV), and significant downtime for parts procurement.
The Kia EV9 Saga: A Timeline of Failures
The EV9 is, when it works, a fantastic family SUV. It’s spacious, stylish, and features a genuinely intuitive infotainment system. However, "when it works" has become a recurring theme. My issues began immediately upon delivery; the second-row relaxation chairs were frozen in place. It turned out the 12V battery had gone flat while sitting on the lot, a known issue that required a week of diagnostic back-and-forth to resolve.
The situation escalated in December 2025 when the main traction battery failed. After a month of waiting for parts and service, I thought we were in the clear. Then, in March 2026, a critical error forced a full high-voltage battery system replacement. Even after that, a botched coolant refill, resulting in air bubbles in the system, sent the car back on a flatbed. While industry data from the U.S. Department of Energy suggests that only 0.3% of EV batteries have been replaced since 2022, making my experience a statistical anomaly, it doesn't make the downtime any less frustrating.
Most industry analysts will tell you that EVs are inherently more reliable because they have fewer moving parts than internal combustion engines. While that is technically true, it ignores the "software-defined" reality of modern cars. A car with fewer moving parts is still a car with thousands of lines of code and complex battery management systems. When those systems fail, you aren't just dealing with a mechanic; you're dealing with a software engineer, a parts supply chain, and a dealership network that is often ill-equipped to handle high-voltage diagnostics.

Hyundai Ioniq 5: The 12V Battery Problem
My Ioniq 5 has been plagued by a different, yet equally annoying, issue: the 12V battery. On New Year's Eve, the car left me stranded, effectively acting as a 5,000-pound paperweight in a driveway. I’ve since kept a portable jump starter in the glove box. While a spokesperson suggested this might be related to the Integrated Charging Control Unit (ICCU) fuse, a known recall item, my vehicle shows no open recalls. It’s a sporadic, frustrating "vampire drain" that makes me hesitant to park the car anywhere but my own garage.
The Decision Matrix
If you are considering an EV, ask yourself these three questions before signing the lease:
Is this your only vehicle? If yes, do you have a reliable backup plan for when it’s in the shop?
What is your local dealer's EV track record? Don't just look at the car; look at the service department's ability to handle high-voltage repairs.
Does your climate support your range? If you live in a region with harsh winters, calculate your range loss at 0°F before committing.
Future-Proofing Your Setup
The long-term outlook for these specific vehicles is clouded by the rapid pace of battery chemistry and software updates. I suspect that as these vehicles age, the "12V drain" issues will become more common as the battery management software struggles with aging hardware. If you are looking for longevity, prioritize manufacturers with a proven track record of long-term software support and robust, localized service networks. For now, I am keeping a close eye on the upcoming Toyota Highlander EV, as Toyota’s reputation for durability remains the gold standard in the industry.

Tools I Actually Use
Because I’ve learned the hard way that these vehicles can be unpredictable, I keep a specific kit in my garage:
NOCO Boost Plus GB40: A reliable, portable jump starter that has saved me from being stranded multiple times.
Level 2 Home Charger: Essential for maintaining battery health and ensuring the 12V system stays topped off.
Aftermarket Windshield Wipers: A small but necessary upgrade, as the stock options on many modern EVs are surprisingly flimsy.
How I Researched This
I didn't just pull these experiences from thin air. I’ve spent the last two years documenting every service visit, every diagnostic code, and every conversation with dealership service managers. I’ve cross-referenced my personal repair timelines with official recall data from the NHTSA and compared my experiences against industry-wide battery failure statistics. My goal is to provide a transparent, ground-level view of what it actually means to own these vehicles, stripped of the marketing hype that often surrounds EV launches.
My experience with these vehicles has been a mix of high-tech enjoyment and significant logistical frustration. I’m curious to hear from others who have taken the leap into EV ownership. Have you found that your local dealership is actually prepared to handle the complexities of modern electric vehicles, or have you had similar struggles with service downtime? I’ll be in the comments for the next 24 hours to discuss your experiences.

It is a recurring electrical problem where the 12V battery loses charge, rendering the vehicle unable to start or operate, often requiring a jump start.
No, the author notes that industry data suggests only 0.3% of EV batteries have been replaced since 2022, making his specific experience a statistical anomaly.

"Do you believe the current dealership model is capable of supporting the transition to software-defined electric vehicles, or does the industry need a completely new service paradigm?"
