2009 Hyundai Santa Fe engine problems

Filed May 20, 2026 · Engine · SC

*The mechanic diagnosed internal engine failure (May 14, 2026). The vehicle is at the second mechanic's shop. *The car stalled twice. The first time, over 20 miles, the air conditioning stopped, followed by the radio, and then acceleration. I pulled over and the acceleration returned but only for a minute. The second time, a clacking noise got louder and faster, and three miles later the engine stopped. I coasted and pulled over but had to shift to neutral and use the parking brake to stop. *The first time was a two-lane road (55 MPH). As I lost acceleration, cars slowed behind me. It took so long to turn off on a side road, the car behind me almost hit me as they speeded up to pass. The second time was a busy two-lane road (45 MPH), but the engine stopped so quickly, the person behind me almost rear ended me. Without the steering, the car crossed the middle lane, and I had to haul the steering wheel so I could pull off to a side street. *The first repair shop said the oil was low and suggested the place that changed the oil did not know what it was doing and perhaps didn't put the cap on right. The oil was dripping over the engine and to the bottom of the housing. After driving it, the mechanic said the Hyundai service center should do a diagnostic, but it was safe to drive. The second repair shop did an oil change to see what was happening with the oil flow. He found metal filings as well as other problems and said it this was an internal engine failure. *The Hyundai service center said the vehicle needed to be towed, at my own expense, to the its center for a $185.00 out-of-pocket diagnostic. *In October 2025, the Hyundai dealership serviced the car for a cylinder head oil leak recall/problem. *There were no warning lights either time--no engine or oil lights came on. There were no symptoms or indications of a problem before the first incident (May 7, 2026).

Vehicle will suddenly shutdown in the middle of the road. This could easily have caused a crash at any time. Several batteries have been replaced due to alternator not charging the battery. Then the battery has to be jumped for emergencies. I have taken the car in for repairs of the recall twice. I was told that the front end would come off and parts would have to be replaced because of the age of my vehicle they would not fit again. I need a solution to this problem.

[XXX] We took out Stanta Fe to the Hyundia Dealership in Columbia, TN 38401. The installed a new rover cover gasket left and service kit. The purpose was to stop oil from leaking into the alternator. I would like to point out we did not see any visible signs of the gasket was leaking. We had our regular scheduled oil change in Feb of 2025 and no report of an oil leak. We had a service event at the end of June 2025 and were told there was a visible leak was present and appeared to be about 3 months old. We took it back to the dealership and reported the recall issue was occurring. This was 7/25 and just outside of a year. The stated it would not be covered under warranty/recall now. I called and complain to Hyundia corporate. Waited 2 weeks to say it would be taken care of by the dealership. Called them today to arrange for bring the car in but they had no record of what I was told by Hyundia corporate. I believe this breaking faith w the whole recall process with the NTSB.

Pulling into driveway. Car engine accelerated suddenly. Was just coasting in. The car wouldn't stop. Hit front of a home. The engine sounded like a race car.
