KIA Complaints

The low beam headlights do not illuminate the highway sufficiently to drive safely. I lowered the aim of my high beam to be able to drive at night and not blind approaching drivers. This is unacceptable for a modern vehicle to be permitted to be sold in this condition.

Without presenting any errors, the vehicle appears to enter some sort of limp home mode which limits speed to 31mph until the vehicle is turned off and re-started. 31mph is well below the speed limit on most public roads and being limited to this speed with no ability to pull over to stop/start the car creates a significant safety hazard to the driver of the vehicle and other motorists.

vehicle is consuming over 2 quarts of oil in less than 1000 miles and it causing the oil light to come on and loss power.

We were driving on interstate at 70 mph. It was sunny and 45 degrees outside. Suddenly with no warning, our front sunroof glass exploded. The bang was so loud that my ear was ringing hours after. Fortunately no car was following closely so no other vehicle was hit with flying debris. Also, our interior visor was closed so we were not struck by any of the flying glass. We pulled off and removed any loose glass that could fly off and proceeded to the dealership. They were submitting warranty information, etc. and provided a rental while we await the repairs. They did mention they had seen this before in a case where the visor was not closed and glass poured into the cabin and implied that it was a worse case than ours.

Instrument cluster does not turn on upon ignition, when in cold weather. this has been a repeating incident, first of which started only 2 months after the purchase. even after 7 separate incidents, and handful dealer visits, car was deemed "okay" because they could not replicate the issue. employees at the dealership have taken pictures and videos but have yet to find a solution to fix this issue, and they further "ask" that if the incident happens again, drive as is so they can see the issue. this is a serious safety issue since nothing is visible including speedometer, rev meter and gas tank indicator, etc. the most recent incident will be dated on the report, but i will attache multiple pictures from different dates as i can recall and recollect.

Front driver side bottom bumper has unclipped randomly. I’ve spoken to a group with other 2023 Kia K5 GT-Line owners and at minimum 30 others have had the same exact clip from the bumper randomly detach. This could cause a hazard for other drivers if the bumper were to detach and possibly hang while driving at a high speed on the freeway.

The engine failed while driving on the highway, putting myself and others at risk. First the car started shaking, then the check engine light flickered. Fortunately, I was able to get off the highway, but I was far from home. The engine failure was confirmed by an independent service center and a dealer. The vehicle was inspected by a third party and since it was still under warranty, the engine was rebuilt. A few weeks later, the check engine light came on again, this time 0420 code. The dealer where I purchased the vehicle called it in to the warranty company, and they have reset the check engine light and asked me to keep driving the car to see if the light comes back on. All of this happened after the car had undergone oil consumption testing, and a previous claim for a new engine had been denied both by the warranty company and the manufacturer.

My vehicle has less than 8K miles. This weekend my horn stopped working (a definite safety problem) and the signal that I had locked my car doors using my fob failed to work. The lights did flash to signal they were locked (I checked just to be sure!) I need to have the vehicle checked before part(s) can be ordered. That requires 2 trips to the dealer instead of one. I was told that this problem is a "recall under warranty". Kia isn't doing anything to keep their customers with this lack of service.

I’ve had to get three oil changes in just five months of owning my vehicle. Honda of Brandon sold it to me with a clean Car-Fax report, but I’m now facing a possible manifold and catalytic converter replacement costing $4,200. When the service department called the warranty company, they claimed it was a catalytic converter issue, but it turned out to be an O-2 sensor, which would cost about $460. One month after purchase, I had to replace the ignition coil and requested spark plug replacements, though I wouldn’t have known if a spark plug was bad. That repair bill alone came to $802.17, just a month after buying the car. Problem with battery. Oil has to keep being replaced and no one knows since not on ground has to be going in the engine. service rpt are Aug/19, 2025, jan 20,2026

Issue: Oil consumption/ low oil pressure indicator or check engine light did not go on. Was driving kids to school and on my way home I heard a loud rattling sound. Pulled over and had it towed. Shop said it didn't have oil, it was dry as a bone. We do regular oil changes every 5k miles and there are no oil leak spots on driveway or in garage. No oil light came on, no check engine light. Hoping this didn't damage my engine as I am at 110,000 miles.
