Engine rattle 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: 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025.

What this problem usually is

Owners in this group hear something before anything breaks. Most describe a ticking or tapping at idle, a rattle that's worse on a cold start and fades as the engine warms, or a noise that comes and goes over weeks. Some report the check engine light following a while later. It's the early-warning end of the engine complaints, and the reports that end in a named part are useful to anyone hearing the same sound.

Is this a known problem?

The manufacturer has sent NHTSA 2 service bulletins or notices for the 2015 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

“Engine started making rattling sounds during startup and when accelerating. Kia dealer said the engine failed and needed replaced. Repair cost were around $9000.00.”

“I had an oil change and then went on a road trip, The trip consisted of two days driving and 1300 miles driven. the engine sounded different so I checked the oil and it did not register on the dipstick. Since then I have been checking the oil once a week and have noticed is will be low. The oil can be a quart to a quart and a half low after just 500 miles.”

Should you keep driving it?

This page can't tell you that. 0 of 36 reports involved a crash. 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.
