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

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.

Driving down the highway and heard a pop and my seats were rising slowly and while trying to make it to the nearest exit only two minutes later my rpm’s started jumping and my engine just shut off and multiple dash lights came on. Had it towed to Kia and after they did an inspection they said that my fuel tank had expanded and was pushing on my fuel lines and pushing my back seats up.
