NHTSA complaint #11739870

Owner complaint summary

I own a 2021 Kia Telluride with approximately 111,000 miles. I initially brought the vehicle to a Kia dealership for an oil consumption issue and engine noise. The dealership diagnosed and repaired a timing chain and tensioner issue, stating the vehicle was “working properly” upon return. After picking up the vehicle, I immediately began experiencing electrical warning lights, including the battery warning light and system alerts (blind spot and general warning indicators). I returned to the dealership, where they performed diagnostic testing and indicated a potential alternator issue, but stated it was in a “borderline” range and that the vehicle was safe to drive. Shortly after leaving the dealership, while driving with my family in the vehicle, the electrical system began to fail. Multiple warning lights illuminated, and the vehicle lost electrical function while in motion. The vehicle ultimately became completely inoperable and shut down in a parking lot, creating a serious safety concern. Prior to the dealership visit and repairs, the vehicle had no history of electrical issues, warning lights, or charging system problems. The dealership later acknowledged that the alternator issue was not present when the vehicle was initially brought in. I am submitting this complaint due to the sudden and complete electrical system failure while driving, which posed a significant safety risk. The progression from no prior symptoms to total failure immediately following dealership service and diagnosis raises concerns about vehicle reliability and potential safety defects related to the charging system.
