Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The display is shows a Check Oil Level error. It comes on then goes off regularly. I have verified that the oil level is OK. Took it into the dealer and he said that this is a common issue and a software fix is coming. The car only has less than 2K miles. I depend on the engine displaying error messages, but they need to be real ones. Online complaints indicate that this is a common error and there seems to be no fix.”
NHTSA complaint #11730905, filed 2026-04“Kia has a known wiring‑harness defect that causes the low engine oil sensor to trigger incorrectly. Despite this, there has been no recall, and new vehicles are still being sold with the issue. The wiring harness is now on back order, leaving me without a car for weeks or longer. The vehicle has plenty of oil, and the dealership confirmed there are no engine problems, yet the warning light keeps coming back because of the faulty harness. This happened 1 day after buying this car new from the dealership lot.”
