“While driving, the vehicle developed a strong odor of engine oil, followed within minutes by illumination of the red oil pressure warning light. Inspection determined that a bolt had exited the engine's timing assembly, broken the timing chain, and punctured the timing cover, discharging engine oil throughout the engine compartment while the vehicle was in operation. Engine oil was sprayed onto hot engine and exhaust components while the vehicle was being driven on public roads. This presents a fire hazard. The same failure also risks sudden loss of engine oil pressure and seizure without warning, which would cause an abrupt loss of motive power in traffic. Approximately twelve days before this failure, the check engine light illuminated. The vehicle was taken for service within two days. The technician was unable to clear the code or identify the cause and advised a dealer inspection. No warning of imminent catastrophic engine failure was provided by the vehicle. The vehicle was towed to a Hyundai dealership, which quoted $6,932.28 plus tax and characterized the work as a "timing repair." This vehicle is equipped with the 3.3L Lambda II GDI V6. I am aware that…”
“My wife was driving the vehicle by the left lane on route 9A northbound on elmsford at a speed around 35 mph. The vehicle suddenly came to stop completely while driving. My wife tried to start it but it didn't start. We called the police to come help us due to the ongoing traffic while the towing was on its way. Our mechanic told us the engine was seized and needs a replacement. The vehicle is a 2018 and has only 118000 miles. We do oil changes periodically every 3000 miles.”
“Catastrophic Engine Failure - Cam phasers blew apart and severely cracked the valve covers. This occurred with no prior warning lights. Minutes before failure, there was engine hesitation and noise and then severely reduced power, causing a safety issue while driving. Vehicle was towed to local Hyundai dealer who identified the cam phaser failure ausing external engine damage of the valve covers and complete loss of oil. This occurred only 3,000 miles after an oil change.”
“Engine Issues: A week ago, on two separate occasions, my Santa Fe cutoff while driving suddenly. A day later, I noticed a rhythmic knocking upon starting my vehicle. The knocking would increase during acceleration and decrease when I let off. I am only at 83,000 miles on this 2018 vehicle. I took the vehicle in for an oil change and they didn't notice anything off about the oil. Afterwards it slightly improved; however, once I was able to get it to the shop they said there were metal shavings in the engine/oil and it was a complete engine failure costing $12,000 to replace. There were no indicators that there was an issue on the dash.”
“Was driving and car turn off on me and wouldn't start I got it towed to Hyundai and they said my engine went out it had oil and everything we don't know why can stopped working has been sitting in my drive way for 3 years because we don't have 13000 that Hyundai told us”
“In September 2024, my 2018 Hyundai Santa Fe experienced an unexpected engine lock-up while driving, creating an immediate safety hazard. Vehicle lost power, began smoking, and posed a potential fire risk. Fire department responded to prevent the engine from catching fire and had to spray the engine compartment with high-pressure water. Following this incident, vehicle remained in Hyundai’s possession for ~9 months for engine-related repairs. When we picked up the vehicle after the prolonged repair period, front-facing camera had completely stopped functioning. This camera has always worked prior to the engine lock-up and was functioning the day of the incident. This was reported to the dealership, Hyundai Motor America. A case manager (Nemesh) took the case. Very supportive, helpful and provided a thorough process for investigating the situation. However, all the sudden case was assigned a new case manager (Bryan) and the process immediately changed and the claim was denied. Given the timing and circumstances, the camera failure appears to be the result of electrical or component damage caused during the engine failure/fire-prevention event. The dealership also…”
