Filed Jul 21, 2026 · Engine · FL

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.

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), the federal safety agency 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.

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.

The 3.3 liter V6 GDI engine failed while driving at approximately 136000 miles. Heard a ticking noise start shortly after leaving home, and had hesitation and shaking upon acceleration from a stop sign, but saw no warning lamps. Went around the block back home to find out the ticking noise was under the hood. Motor oil was almost 3 quarts low, but only 2/3's of the way through the service interval. Checked for leaking, saw none dripping, but did see oil on the under of the rear differential. I then let the car run for minute or so in the garage and looked for leaks. I saw no active leaking and ticking was quieter, so I drove to a close gas station to get a little gas and test drive, still no warning lights. On the way back, about a mile from home, the engine light came on, despite the ticking sound being gone. Within a quarter mile, at the next stop sign, I let off the brake to accelerate and the car started rolling backwards, causing the vehicle approaching from behind to swerve into the turn lane. The vehicle was no longer running, and wouldn't restart. Towed to local mechanic and was told 2 days ago the engine was seized, and replacement was needed. I have not contacted any dealership or the manufacturer, as I the second owner and do not have a warranty. However I have spent the last 2 days reading seemingly 1000s of articles and forum posts related to this engine, whether it be in a Hyundai or a Kia. Several of the articles I have read about this 3.3 liter GDI Lambda -II engine and it's horror stories, referenced this the federal safety agency site as a place where complaints can be made, so here I am. Many articles describe the same problem.. hesitation... ticking.. sudden mysterious oil loss... little, if any warning... complete failure while driving, putting safety at risk. With the problem with engine so blatantly rampant, it is my fear that after I scrap this vehicle, there will be a recall. Over the phone quotes, and online pricing have ranged from $7500-20000 for repair.

My 2015 Hyundai Santa Fe GLS 3.3L engine started ticking sound while driving in residential are with the speed below 25miles. Within seconds, Engine started screaming and dropped power in the middle of the road. It is a huge security and life threatening risk. I was lucky that I was driving in residential area with very slow speed, and just imagine if it happens in the middle of the freeway cruising at 65MPH. It is at 107k miles and not sure what to do at this time. Hyundai better recall there 3.3L V6 engines and help us our here. My vehicle is now dead and I have nowhere to go to get help because it a huge cost to get it fixed.

We were on our way home from the children's hospital in Philadelphia for my daughter (4 hours away from home) and my 2015 Santa Fe with the 3.3L motor began to knock. My dad (who is very mechanically inclined) pulled over at a gas station and checked oil and other fluids. It was low, even though I just had oil changed 900 miles before and it was checked before our trip to the hospital. We bought oil and put it in. Knocking was still there but was not as loud. We got back on interstate. Few miles up the road it completely lost power, extreme knocking, no lights on in the dash or any gauges out of normal range. He checked oil and it was completely empty but there was no oil trail or anything. We coasted into a crossover and that's when he saw the connecting rod under the car.

The engine is continually knocking. It has caused the powertrain system to start to fail. The interior portion of the car with electrical is malfunctioning and causing the car to lag. Many attempts have been taken to get the vehicle fixed to no avail. $1,000 just to take out the engine to diagnose the problem.

Out of the blue, the engine started knocking badly. Immediately pulled over and checked engine oil which was extremely low. (This was odd since I regularly check oil levels and keep up with oil changes.) I happened to be very close to an oil change shop, drove over and they did an oil change. They found silver and gold metal shavings in the old oil and topped off with new oil. The knocking was muted but came back by the time I got home. I have not driven the car since. Seems to have the same fate as many other Hyundai vehicles in the current recall, but this has the 3.3l engine. I've also found there is a petition to add the 3.3l engine to the recall.

Engine with rod bearing failure occurred at 108k miles. No check engine light warning came on to notify with engine knock sound as the only indicator that there was a mechanical issue. Regular oil changes have been done on the vehicle however oil levels were low when checked on the day of engine failure (no low oil light came on). 3.3 L V6 engine is not covered under Hyundai’s KSDS Software Update (Campaign 966) and extended warranty however issue is the same as other covered models and years.
