   Sudden power loss, stalling or engine seizure

   • 29 complaints (41%)
   • median 107,500 mi at 7.2 yrs old (10 state mileage)
   • 3 mention a crash, fire or injury
   • filed 2019–2026

   Owners describe the engine suddenly losing power, stalling, failing to accelerate or seizing, often while driving and in some cases at highway speed. Some complaints say there was no warning light beforehand, while others describe a check engine light that came on or flashed first. According to complaints, the dealer often replaced the engine, the knock sensor or an engine harness, and in some cases the failure returned afterward. Where mileage is given, most reports are above 100,000 miles, with the lowest near 32,000 miles.

   What to check: Ask for records of any engine or knock sensor repairs, including whether the engine was replaced and under what coverage. On a test drive, check for hesitation or loss of power under acceleration, and for any check engine or flashing warning light.

   “Took car in 1 month ago for service campaign (software update) 2016 Santa Fe Sport 83,000 miles. While driving on freeway yesterday engine light started flashing and car went in to 'safe mode' was able to go about 1/2 mile before it completely stopped.. Had it towed to dealership was informed today the engine failed. Waiting for approval from Hyundai for new engine. I'm completely stuck in this vehicle now. No one will pay what is owed and I will lose trading it in.”

   NHTSA complaint #11220673, filed 2019-06, 83,000 miles

   “The engine light started blinking and my car would not accelerate anymore. I took it to the mechanic immediately, who said that there was an engine recall. I contacted the dealership, but they cannot do an initial inspection for more than 2 months. It would likely take another 2-3 months after the inspection before the engine can be replaced. …”

   Repairs delayed or denied under recall or warranty

   • 28 complaints (40%)
   • median 93,500 mi at 7.3 yrs old (9 state mileage, few)
   • 6 mention a crash, fire or injury
   • filed 2017–2026

   Owners describe engine and other repairs that were delayed or declined because a recall or warranty was not completed, not assigned to the vehicle, or not covered. According to complaints, the dealer said a campaign repair could not be done, could not schedule an inspection for months, or said the claim was refused because of an earlier recall or a rebuilt title. Some owners say they were not notified of a recall, and others waited for manufacturer approval for an engine replacement. Where mileage is given, reports range from about 60,000 to about 133,000 miles.

   What to check: Ask the dealer to check open recalls and campaigns for the vehicle, including any knock sensor detection update or campaign 953 mentioned in complaints, and ask for any coverage decision in writing. Check the title history, since a complaint cites a rebuilt title as the reason for a refused repair.

   “The engine seized up and hyundai refused to approve my claim al though i had the extended warranty. Reason for the denial because a recall in 2019 was not performed. I had purchased the vehicle in 2023 used from Rick case honda.”

   NHTSA complaint #11737803, filed 2026-05

   “Engine siezed, causing me to have to tow my vehicle. I was moved in the military to Germany in 2019, I had to have no open recalls on the car before I shipped it overseas. I completed a recall on the 5th of January 2019. On the 10th of January, Hyundai activated another recall on the vehicle. I was unaware of this recall and shipped my vehicle to Germany on the 16th of January 2016. The car returned from Germany in September of 2023. I had zero issues with this vehicle while I was over there, no check engine lights, no warning lights, nothing. …”

   Knocking noise, knock sensor codes or bearing wear

   • 18 complaints (26%)
   • median 131,000 mi at 9.2 yrs old (6 state mileage, few)
   • filed 2023–2026

   Owners describe a knocking sound from the engine, often with a check engine light or a knock-related fault code. Some complaints describe connecting rod or bearing failure, and in some cases the knock sensor was replaced without the problem ending. According to complaints, the dealer diagnosed a faulty knock sensor or bearing wear, and some reports say a knock sensor detection update was needed before a repair. Where mileage is given, all reports are at about 64,000 miles or more, and most are above 100,000 miles.

   What to check: Ask whether any knock sensor detection update or campaign 953, cited in complaints, has been completed on the vehicle. At startup and on a test drive, listen for knocking and check for stored knock sensor or engine codes.

   “My car only has 93,000 miles on it. I was driving home from work and all of a sudden the check engine light came on while I’m on the freeway. I made it home and went to research then all of a suddenly the check engine light would just start flashing. I got it checked by a mechanic. They said that there was metal shavings in the oil which I have no clue how that would happen and that there was a code for knocking.”

   NHTSA complaint #11735585, filed 2026-05

   “The vehicle lost power, and the engine started to make a knocking noise, and the check engine light came on. I plugged in the obd2 scanner and the p1326 code came out. It was a knock sensor that needed to be replaced. I replaced the sensor that the issue got worse. I looked up online about this issue and then I found a video of that explained the incident. The manufacture of the crank at the factory did not properly clean the holes of the oil passages. …”

   “I turned off the car and went inside the house. I was outside and could smell smoke. I walked to the front of the house and saw my neighbor who was calling 911 due to flames from my engine. The flames reached the yard and my garage where minor damage occurred. The vehicle was completely engulfed in flames before the fire department extinguished it.”

   NHTSA complaint #11716330, filed 2026-02

   “As we were driving down the interstate we began to see smoke coming out our vents and after a few seconds saw flames coming from the passenger side of car. We quickly tried to pull over but brakes weren’t working. Safely pulled into grass median. Luckily we were able to quickly exit through the driver door. After about 30 seconds the car was engulfed in flames.”

   • median 104,500 mi at 9.8 yrs old (2 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2025–2026

   Owners describe engine oil being used faster than expected, sometimes with oil or check engine lights before a failure. Some complaints describe a dry dipstick, metal shavings or debris in the oil, and no oil warning before the engine seized or lost power. A complaint also says the dealer stated the pistons were not covered, while a separate complaint describes a dealer inspection that found no reason for the failure. Where mileage is given, reports range from about 77,000 to about 132,000 miles.

   2 related service bulletins

   What to check: Ask for oil change records and check the dipstick level and oil condition during a pre-purchase inspection. Ask whether the service bulletin for higher-than-expected oil consumption has been performed on the vehicle.

   “The engine seized up on the highway with no warning signs or alerts and lost all power to the vehicle putting family at risk on the highway speed. Mechanic confirmed engine seized and metal debris after draining oil. Oil changes are done on timely basis within 5000 miles. Most recent where synthetic oil used and was just at 5000 mark.

   NHTSA complaint #11700734, filed 2025-11

   “The engine powertrain system, specifically the internal engine lubrication, timing chain, and camshaft sensors. The vehicle's Theta II engine suffers from systemic, excessive oil consumption, which starved the engine of lubrication. This caused the timing chain to stretch and mechanically fail, and compromised the camshaft sensors. The vehicle is currently un-repaired and is available for inspection upon request at Hyundai of Downtown LA. While driving, the engine suddenly stalled and completely shut off mid-drive without warning. …”
