On multiple occasions, the HEV system warning light and check engine light activated while I was driving at highway speeds. Immediately after the warning lights appeared, the vehicle suddenly decelerated, putting me and other drivers at risk. This issue has occurred several times and is clearly a serious safety hazard. Each time this occurred, I brought the vehicle to an authorized Kia dealership ([Dealership Name]) for inspection. However, despite the vehicle being under the Kia hybrid system and/or powertrain warranty (10 years/100,000 miles), I was recently informed that the necessary repairs would not be covered under warranty.

Reading this record
No unusual pattern of severe incidents in the complaint record.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
