ENGINE — Filed 07/12/2026

Driving on highway no warning lights appeared the car made a loud pop noise and heavy smoke appeared from under the hood. Immediately pulled over and noticed all of the oil poured out and was nasty looking. The car was up to date on oil change. My car was towed home and bone dry no oil and no coolant the engine now had loud knocking and needs to be replaced for failure. The car was looked at by independent mechanic. Miles on the car are 152010. I had no warnings and up until the issues the car was serviced and cared for.

I was driving down the road ( a busy Farm to market road) and my car lost power and died. Luckily i got off of the road. I tried to start the car again, but it kept dying. I had my son in law come help me move the car to a friends house so that I could get it to the dealership. It was after hours. I regularly get my oil changed and when my SIL checked the oil there was none on the dipstick. My SIL put oil in the car. My car was coming up on being due for a oil change. I am a single woman close to 50 yrs old and take my car in for maintenance. I then had my car towed to the local dealership to have an assessment done to find out what the issues is. The dealership reported that the timing was off and that bank 1 and 2 of the camshaft needs replaced. There is a known issue with the engine of this car doing the exact same thing my car did. There were no warning lights on to indicate a problem with the car. I inherited the car for my Mother In Law that passed away. She bought the car brand new and had it serviced regularly.

The engine failed due to complete and sudden oil loss. The vehicle is currently at Fremont Hyundai and available for inspection. Safety risk: the engine failed while driving on the highway with children in the vehicle. A check engine light appeared with no prior warning, the vehicle immediately lost power and stalled, requiring an emergency exit and tow. This is a direct collision risk at highway speed. The failure was confirmed by an independent mechanic who found zero oil in the engine and identified it as a known Hyundai defect. The vehicle was then towed to Fremont Hyundai, which is currently conducting diagnostics. The vehicle has been inspected by an independent mechanic and by Fremont Hyundai [XXX] ). No police or insurance involvement. There were NO warning lights, oil pressure alerts, or symptoms of any kind prior to failure. I purchased the vehicle in 2024 and maintained regular oil changes and checkups with receipts. The last oil change was performed a few months before the failure. No mechanic ever flagged low oil. The only warning was a check engine light that appeared seconds before the engine stalled. I have incurred $900 in towing costs as a direct result of this failure. Fremont Hyundai is now requiring me to pay $280 for a diagnostic, followed by $890 for a two-week oil consumption test. They have also stated that if the engine does not pass the initial diagnostic, they cannot help me at all. Given that the engine ran completely dry of oil, it is highly unlikely to pass. This means I am being asked to pay fees for a process the dealership already expects to fail, leaving me with no path to resolution and a car I cannot drive. The 2015 Hyundai Santa Fe is included in a class action lawsuit (Cho et al. v. Hyundai Motor Company) over this exact defect.

2015 Hyundai Santa Fe Limited, 3.3L Lambda II GDI V6, ~102,000 miles. In December 2022, an authorized Hyundai dealer replaced three specific parts under a Hyundai recall/campaign (records requested). On Sunday [DATE] at approximately [TIME] PM, I was driving on [FREEWAY], [STATE], at 55–70 mph at night. With NO prior warning — no warning lights, no chimes, no loss of power buildup, no knocking, no engine protection mode — the engine suddenly and completely died. The failure was instantaneous. There was no limp-home mode and no opportunity to reach the shoulder under engine power. The vehicle lost forward momentum and rolled backward in a live highway travel lane, where it remained stranded until a tow truck recovered it. No injuries. The 12V battery and electrical system remained fully active throughout. The instrument cluster was operational and capable of displaying warnings before the failure. None were displayed. Dashboard warning lights illuminated only seconds AFTER the engine had already died — a post-failure consequence of engine shutdown, not a pre-failure warning. An independent mechanic diagnosed a seized engine due to loss of oil flow. No oil pressure or low-oil light had ever illuminated. The vehicle was then transported to the Hyundai dealer that performed the 2022 service; they promised a diagnostic call and have not provided one or any written diagnostic. This failure mode matches Hyundai TSB 24-EM-003H (15yr/150k extended warranty for 3.3L Lambda II engines in 2013–2019 Santa Fe), NHTSA Recall 21V-727 (acknowledging stall risk at highway speed), and the active class action Burns v. Hyundai Motor Company (C.D. Cal. 2025). Hyundai's KSDS is documented to trigger a blinking MIL, audible chime, and reduced-power Engine Protection Mode upon bearing wear. None of these protective behaviors occurred.

I purchased this vehicle one year ago from a used car dealership with 148,000 miles on it. Within a few months it was throwing crankshaft position, sensor codes, camshaft codes, and burning oil. I cannot bring my RPMs above two without my check engine light coming on and blinking. My car will go into limp mode. Hyundai does not have my car included in the engine recall they only have the sport Santa Fe included. They released an extended warranty for 150,000 miles but by the time that was put into place my car was at 151,000 miles so it was not eligible.

On 08/15/2025 I started the vehicle and heard a ticking noise that lasted for 3 seconds and stopped. The same noise happened when I would start the car in the mornings. It never lasted more than 3 seconds and I wasn't too sure what the noise was. There was no engine lights that came on so I wasnt too worried about it. On 8/21/2025 my husband went to the store and when he came back the car shut off while backing into the driveway. He said it made a weird noise and just shut off. We tested the battery but it was still charged. We brought it to our mechanic and he called us 15 mins later saying he found metal shavings on the oil filter and the engine had seized. He recommended going to the dealer, which is 90 miles away. Around the 15th we had received the warranty extension for 15 years/150,000 miles from Hyundai talking about a knocking sound that can lead to engine seizure. So I called the dealer and they said to bring it in. We got the car towed to the dealer on 8/26/2025. On 09/04/2025 they called to let us know that they ran the test on the engine but Hyundai was not going to help due to the car having 176,000 miles. They agreed the engine seized due to rod failure but wasn't going to offer Goodwill assistance, even with the service history we submitted from our carfax that showed regular scheduled maintenance recorda. We bought the car on 03/08/2025 when it was at 170,000 miles. I knew about the other open recalls and had them fixed on 06/12/2025 ( after being delayed from the dealer for 2 months because they couldn't get the parts for the auxiliary canister). Luckily the car died in the driveway and not in the middle of traffic. Hyundai has known about their Lambda engines having this issue and the KDSS recall was not available for this car which could have triggered a lifetime warranty on the engine. I barely had the car for 5 months.
