The Verdict

Rates best of the six scored K5 years so far, with only two complaints and one electrical recall, though it has had little time to collect more.

Top Issues to Watch

Should You Buy the 2026 Kia K5?

Reliability standing is excellent so far, the best of the six K5 model years we score. Against other 2026 sedans, it sits close to average. The 2025 K5 rates good but worse, and it has carried far more complaints. Part of that gap is age, since a new model year has had little time to collect filings.

Owners have filed only 2 complaints, and one involves an injury. The data does not say what happened, so no repeated symptom shows up. Federal recall records show 1 recall, in the electrical system. The federal crash-test rating is 5 of 5 stars, which is the top mark.

Before buying, ask for proof that the electrical recall repair was done on the exact car. Request the service history too. If you want a year with a longer record, the 2025 has 29 complaints and 2 recalls, so read those filings first.

ELECTRICAL SYSTEM

Kia America, Inc.

An instrument panel display that fails to show critical safety information, such as the speedometer, tire pressure, or warning lights, increases the risk of a crash.

Remedy

The instrument panel display software will be updated over-the-air (OTA) or by a dealer, free of charge. Owner notification letters are expected to be mailed March 26, 2026. Owners may contact Kia Customer Service at 1-800-333-4542. Kia's number for this recall is SC361.

Used Buying Checklist

Key things to inspect or verify before purchasing a 2026 Kia K5.

Inspect the entire panoramic moonroof glass in bright light for chips, cracks, or star marks.
Ask whether the moonroof glass has ever been replaced and request the repair paperwork.
Run the VIN through federal recall records and check for any open moonroof campaign.
Check seat tracks, carpet edges, and headliner seams for small glass fragments left from a prior shatter.
Open the sunshade fully and look for headliner damage or a poor seal around the moonroof frame.

2026 Kia K5 Common Problems by Component

2 owner complaints grouped by vehicle system.

UNKNOWN OR OTHER

2 complaints

The panoramic moonroof glass shatters on its own while the car is moving. It bursts outward with a loud bang, and when the sunshade is open, glass falls into the cabin onto the people inside. Reports describe no warning beforehand and no visible sign of impact. One failure happened at 3300 miles, and one occupant was injured. A sudden blast and falling glass at highway speed can startle the driver and raise crash risk. None of the reports describes a dealer diagnosis or repair.
