The 2024 Kia EV9 is a futuristic all-electric SUV loaded with tech, but even new models can have serious defects. While most vehicles perform as expected, some turn out to be lemons. At Lemberg Law, we track consumer complaints to identify patterns and help owners understand their rights under state and federal lemon laws. Here are the top three issues EV9 owners are reporting. Let’s dive in.
Most Common Problems
Here are the three most common issues owners are reporting:
Infotainment system failures, including frozen displays, blacked-out screens, and malfunctioning controls
Battery and charging system defects, including BMS errors, failure to charge, and total power loss
Excessive vibration and instability at highway speeds, sometimes affecting steering or safety

Infotainment System Failures and Blank Screens
The EV9’s wide panoramic screen and digital control system are a major selling point. But many owners are finding that these systems are unreliable, glitchy, or completely unresponsive.
What owners are reporting:
Screens freezing while driving or going completely black
Navigation, climate controls, and audio systems shutting off unexpectedly
System restarts that don’t resolve the issue
Some complaints describe driving without any functioning screen, which affects climate controls, media, rear cameras, and essential vehicle information. In some cases, dealerships are unable to reproduce the problem, leaving owners with a recurring defect and no clear solution.

Battery and Charging System Failures
Battery problems are a serious concern in any electric vehicle, and the EV9 is no exception. Owners report a range of charging issues and battery-related failures, often accompanied by Battery Management System (BMS) warnings.
Examples from complaints include:
BMS lights appearing suddenly, followed by the vehicle refusing to start or charge
Charging ports that malfunction or fail to register the cable
In some cases, the battery has had to be replaced entirely on new vehicles
Several owners report losing all power after driving, leaving the EV9 stranded. This issue appears more than once in the dataset and often leads to a tow and long service delays, with parts sometimes on backorder. These failures can affect both home charging and fast-charging station compatibility, making it hard to rely on the vehicle day to day.
Vibrations and Instability at Highway Speeds
Many owners are also reporting problems with ride stability and steering vibration, particularly at highway speeds. Some describe a noticeable shake in the steering wheel, while others say the entire vehicle feels unstable above 60 mph.
Difficulty keeping the vehicle straight in lane without overcorrection
A sense of looseness or wobble, especially in windy or uneven conditions
Several owners have had the tires rebalanced or wheels aligned, but the issues persisted. In some cases, multiple service visits failed to resolve the problem.
What To Do if Your 2024 Kia EV9 Has Repeated Problems
When repeated defects disrupt safety, usability, or performance, you may have more than just a bad experience—you may have a lemon.
Under state and federal lemon laws, you could be entitled to free legal help and compensation. If your EV9 has required multiple repairs for the same issue or has been out of service for an extended period, it may qualify.
At Lemberg Law, we help car owners assert their rights under the law. You don’t pay us unless we win—and Kia may be required to cover your legal fees.
