Recalls, Specs & Safety Report

Expert Verdict
⚠️Elevated Concerns

The 2023 KIA K5 presents significant reliability concerns due to multiple recalls affecting crucial systems like the powertrain and airbags. Given the average failure mileage of 43,308 miles and a peak failure range of 0-20k, owners may face substantial issues early in ownership.

Key Factor:Multiple critical recalls

📋Why This Matters

The defects outlined in the recalls are particularly alarming since they involve critical components such as the powertrain and airbags. For instance, a malfunction in the automatic transmission could lead to a complete loss of drive power, which is not just an inconvenience but poses serious safety risks. Moreover, improperly deployed airbags can leave occupants vulnerable during crashes, making these issues pressing for current owners and prospective buyers alike. A clean track record is essential, especially in the competitive midsize sedan segment where safety and reliability are paramount. The fact that this vehicle has multiple recalls raises red flags about manufacturing quality and long-term reliability, making it critical for buyers to stay informed about ongoing updates from KIA regarding these issues.

The kia since bought brand new would have alignment issues even after getting alignments every 3-4 months and the dealership claim that they don’t whats causing constant misalignment after seeing theres no signs of external damage. Due to the misalignment it wears down the tires and made one of my tires explode on the road. Also the door seal on the driver side gets a chunk ripped out from just opening and closing the door over time. Also the breaks, whenever I break from speeding to slow down the speed the steering wheel shakes as well

UNKNOWN OR OTHER

I am submitting this complaint regarding unresolved safety recalls affecting my Kia K5: Recall SC356 and Recall SC346. I have contacted my authorized Kia dealer multiple times over the past several months, yet no remedy has been provided. Most alarmingly, I was informed today that my recall “ticket” was closed without any repairs being completed, which is unacceptable. Recall SC356 involves a damaged fuel tank check valve that can allow air to enter the tank, causing it to expand and potentially contact hot exhaust components. This defect creates a serious fire hazard and poses a risk of injury, death, or property damage. Recall SC346 involves a supplier defect where the C-pillar garnish face plate may delaminate and detach from the vehicle. According to NHTSA (25V493), a detached face plate may become a road hazard, increasing the risk of a crash. Warning signs include looseness, rattling, or wind noise. Both recalls represent clear safety risks, yet Kia and its dealer network have failed to provide a timely remedy or interim solution. Closing a recall case without performing mandated safety repairs is deeply concerning and exposes me and other road users to unnecessary danger. Due to the prolonged delay, repeated dealer contact, and continued exposure to known safety hazards, I am requesting: 1.Immediate reopening and escalation of my recall case 2.Prompt completion of all recall repairs or a clear timeline 3.Consideration of compensation or goodwill due to extended delay and safety risk

10/25 I was traveling, and my car sudden loss of power, while in traffic.. almost causing accident. 10/28 I was traveling on interstate, and my car sudden loss of power, while in traffic.. almost causing accident. This is ridiculous.. When I hit the gas sometimes, feels like it fluttering and jerking. I’ve reported multiple times over the years and this one having hesitation when driving this car. Manager drove it was concern, mechanic talking about it’s the way the car supposed to be.

While driving my car i heard a loud pop come from the rear of the car. Vehicle began driving poorly as if it could not get proper fuel. I took car to dealership on October 3, 2025 where fuel system was tested and failed all 3 stages of recall for fuel system. Fuel tank had expanded straps and clips had broken and was deemed unsafe to drive. Kia placed the vehicle on hold.at the dealership with a do not repair until further notice. As of today October 27, 2025 the car has still not been repaired and is still on hold at the dealership. Kia has not determined if it is safe to repair the vehicle and return to owner (myself). I however do not feel safe to drive this car as I am lucky to be alive and that it didnt explode when the fuel tank expanded. Hopefully my case can help save someone else from being placed in danger with this issue.
