On Saturday,XXX, my vehicle was serviced (oil change and tire rotation) at Berwyn Kia, [XXX]. Shortly after leaving the dealership, I noticed a vibration that developed into a thumping noise from the right rear, worsening at highway speed. I pulled over and found three lug nuts missing from the right rear wheel, and most of the remaining lug nuts could be turned by hand. The wheel was at risk of separating from the vehicle. The dealership sent a technician to help me get back on the road. I have not driven the vehicle since. I am reporting this so there is a record of a wheel-retention safety failure following dealer service. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT…

Power lose while accelerating (Especially on the highway), misfire causing rough idle. Code reading P0301 for fuel injector in cylinder 1. Kia is aware of this issue and has a TSB out for it however will not cover for the cost to replace the fuel injectors. Because of this issue my car does get up to speed in an appropriate amount of time causing a safety concern no only for me but for cars around me. This is also not a constant misfire and is unpredictable when it will happen.

The rear cargo window spontaneously shattered while car was parked. The car was taken for repair to Auto Glass Systems in Springfield Illinois. They do all the repairs for the Kia dealership locally. Upon inspection, they reported that the glass had no point of impact and was caused by an internal defect which was confirmed by the shatter pattern. They said they have had numerous repairs for the same spontaneous, shattering in Kia Sportage windows and suggested that we file a report.

When driving at speeds slightly above 50 mph between 1,700 and 1,900 RPM, maintaining light pressure on the accelerator pedal causes a noticeable physical vibration and shaking throughout both the pedal and the vehicle. To mitigate these concerning symptoms, I intentionally have to press down harder on the gas pedal, which helps immediately stop the shaking. This issue has been occurring consistently over time. While it has not resulted in an accident so far, it could raise safety concerns. I have reported this condition to Kia Customer Care twice, but no appropriate action or resolution has been provided.

I am reporting a recurring and unresolved acceleration issue with my 2023 Kia Sportage. The vehicle intermittently continues to accelerate or maintains elevated RPMs even after I release the accelerator pedal. This has occurred multiple times and creates a serious safety concern because the vehicle does not decelerate as expected. The vehicle has been taken to an authorized Kia dealership multiple times for the same concern. Several components have been replaced, including the throttle body, but the acceleration problem continues to occur. The issue has also been observed during a dealership visit. Because the problem continues despite repeated repair attempts, I would like to formally…

My daughterâs 2023 Kia Sportage SX Prestige has an instrument cluster that intermittently goes completely black while the vehicle is being driven. When this occurs, the driver cannot see the speedometer, warning indicators, or other critical vehicle information. Ferguson Kia inspected the vehicle and documented that the âcluster side of screen [is] INOP.â The technician reset the screen, performed variant coding, verified systems were up to date, removed and inspected the head unit/connectors, verified pin tension and fuses, and found no DTC codes. The screen remained inoperative. Ferguson Kia diagnosed an âinternal electrical failureâ and recommended replacement of the head unit.…

My child is [XXX] old, and as he has grown, I have noticed significant problems with the way he is positioned and supported in this car seat. He frequently sits too far forward and does not appear to have adequate support to keep his head and body in a safe, comfortable position.There have been multiple occasions during car rides when my child has choked or struggled because he is positioned so far forward. The design of the base does not seem to allow him to lean back sufficiently, which causes him to slump forward rather than remain properly supported. This is especially concerning when he falls asleep. His head falls completely forward, and the seat does not appear to provide adequate…

I own a 2023 Kia Sportage Pro While driving to work, I heard an explosive sound that sounded like a gunshot on the top of my vehicle. I pulled over to see that my sunroof had exploded. I checked for any objects that may have hit it, and the only thing that was in the top of the roof was glass. Thankfully, my cover was closed on my sunroof for a glass would have been all over causing possible injury.
