Overheating on other Sorento years

Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025.

What this problem usually is

Most owners in this group notice the coolant before they notice the heat: a reservoir that keeps dropping, a sweet smell, or a bright puddle under the front of the car. Across the vehicles on this site, about four in five of these complaints mention coolant, a leak or a puddle, and roughly two in five mention the temperature gauge or overheating.

Is this a known problem?

The manufacturer has sent NHTSA 2 service bulletins or notices for the 2016 Kia Sorento that deal with this problem. Newest first.

Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

What owners wrote

“Around 140k miles the engine started to randomly overheat. We changed the serpentine belt as well as all hoses. The engine then started to burn large quantities of oil. At 142k miles it failed all together and we are now looking at having to purchase a new engine or a new vehicle. After doing some research I read that this was a common issue with the 3.3L V6 Motors and felt the need to provide my case as well.”

“Was driving down the street no lights on the dashboard no overheating no warnings whatsoever and I heard a click and the engine just went out and the Dashboard lit up if this had happened on the expressway, it could’ve been very dangerous It appears the engine is seized, but it had oil . Apparently, this is become a common problem with this vehicle. Once they hit over 100,000 miles.”

“I am experiencing coolant leaks possibly due to head gasket or engine bolt malfunction. I have received and extended warranty letter from kia but the dealers are saying kia has not provided a solution. The extended warranty is for 15 year/180,000 miles. I am currently at 172,000 miles and am concerned by the time a solution is provided to the dealer i will be out of the warranty period.”

Should you keep driving it?

This page can't tell you that. 0 of 121 reports involved a crash and 1 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
