What Owners Say

Engine rebuild or replacement

"Metal shavings in engine. Oil burning a problem as well"

Anonymous, MO (2018 Hyundai Kona Unsure)

"The engine started to have a knocking sound while driving on the expressway, just a little at first then growing louder. The car had approximately 91000 miles on it. While trouble-shooting found the oil slightly low, it had been burning oil for the last 6000 miles but was getting worse. Continuing to drive the engine seized up, from the start of the knocking sound to the seizing was 20 miles so it happened very rapidly. Took the car to the dealership and a new engine was installed under warranty."

"hesitates when putting foot on gas peddle"

Anonymous, MA (2018 Hyundai Kona Limited 2.0-L 4 Cyl)

Engine Minor

Accessory belts and pulleys, engine computer, engine mounts, engine knock or ping, fuel leaks, oil leaks.

What Owners Say

Oil leaks

"There was a leak from the oil pan at 86000 miles that was repaired under warranty. The oil level continued dropping after the repair though likely tying into the thrown rod that happened later so that was more oil burning than oil leak."

Climate System

AC compressor, blower (fan) motor, condenser, evaporator, heater system, automatic climate system, electrical failure, refrigerant leakage.

What Owners Say

Engine Electrical

Alternator, starter, hybrid battery replacement, hybrid battery related systems, regular battery, battery cables, engine harness, coil, ignition switch, electronic ignition, spark plugs and wires failure, auto stop/start.

What Owners Say

Coil

"Check engine light stayed on car started but ran roughly. Happened twice, first was at the 4 year mark May 2022 and one coil was replaced, second was in Dec 2023 and 3 coils misfiring and replaced. Codes P030100, P030300 P030400 Dealer replaced coils and spark plugs. Work was done on extended warranty. previously they had replaced one of the coils for similar reasons. Having the ability to diagnose the problem with a code reader saved time and money when identifying the issue. First coil change was covered under 5 year warranty, the second was covered under pre purchased extended warranty. when problem occurred dealer was quick to have the car brought in and serviced before any major problems occurred."
