What owners report
“The ICCU failed which was part of the recall. Kia is unwilling to honor repairs beyond the 100,000 mile warranty which is unacceptable because there is still no resolution and it is subject to potential future failure. I need an extended warranty.”
filed Mar 21, 2026
“My car was / is one of thousands of Kia cars based on the eGMP platform to experience an ICCU failure. This is believed to be a design issue. While the repair was covered, reports indicate that the problem is not solved and will re-occur in time.”
