The coolant reservoir on these Kia models was designed with a coolant overflow port located in the rear of the reservoir. During normal vehicle operation, coolant level may rise at or above the overflow port which can seep out of the coolant reservoir, therefore causing coolant to flow out and accumulate around the center seam of the reservoir. This may lead technicians to believe the coolant reservoir is faulty.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10234602-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10234602-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10234602","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"KIA","model":"K5","year_from":2021,"year_to":2023,"match":"exact","vehicle_ids":["2021_kia_k5","2022_kia_k5","2023_kia_k5"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
