STRUCTURE:BODY

As I was driving the hood opened breaking the windshield which obstructed my view and caused me to veer off-road and crash.I acquired the vehicle less than a year ago and only learned of a recall for hood latches from the tow truck driver. afterwards. I had no prior problems with the latch opening and I was not physically injured but my vehicle is a total loss.

AIR BAGS

During a severe accident in which the cars collided from both the back and front at most likely over 50mph, the air bags did not deploy. In such a case, I feel as though they should have gone off as there was severe whiplash and the cars hit at such a fast and hard speed. My safety was impacted severely as if the cars around did not hit the way they did, I believe I could have died. It is extremely concerning that they did not go off when such large amounts of damage were done. In addition, there have been over 50,000 recalls done for air bags not working in this exact vehicle. In addition, the vehicle is being checked in the next day for additional damages and they will confirm the air bag issues. Police as well as insurance providers were shocked that the air bags did not deploy in such a severe case. No warning messages or lamps were on when the accident occurred or before. This is extremely concerning and I now fear for my safety even further if I were to purchase this vehicle again. It is a terrifying thought that I could have died due to a car malfunction.

ENGINE

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. I always changed the oil when told to do so, and when I returned from Germany it was the same thing, no issues and always completed oil changes when it was needed. I had no idea of the recall, Hyundai was sending it to an address I no longer lived at. I had no reason to take my vehicle to Hyundai to check for recalls. On [XXX], my vehicle engine stopped working at 84622 miles, and Hyundai said that it would be covered under warranty, but because I did not complete the recall that was activated on the 10th of January 2019, they denied the warranty and now my car is worthless.

Dear NHTSA, I'm reporting a recurring safety issue with my vehicle's door latches. All four doors have, at different times, become completely stuck—unable to open from inside or outside. This creates a serious risk, especially in emergencies where quick exit is critical.

Subject: Engine Failure Due to Bearing Defect – No KSDS Recall Notification Vehicle: 2016 Hyundai Santa Fe Sport VIN: [XXX] Date of Purchase: April 2016 Complaint Summary: I am filing this complaint regarding my 2016 Hyundai Santa Fe Sport, which experienced catastrophic engine failure due to the known Theta II GDI engine bearing defect. Hyundai has an active class action settlement covering this defect, which requires owners to install the Knock Sensor Detection System (KSDS) update to be eligible for free repairs or the lifetime warranty. Despite owning my vehicle since April 2016 and holding clear title in my name for over 6 years, I never received any notice or communication about this required software update. Hyundai’s records still list the prior owner, Hertz, even though I have maintained valid registration and insurance in my name since the purchase. This lack of notice prevented me from having the KSDS update installed before the engine failed. I understand this defect does not show as an open safety recall on the NHTSA database because Hyundai classified it as a Product Improvement Campaign under the class action settlement. This does not change the fact that it is a known safety hazard and Hyundai failed to properly notify me, which denied me the chance to protect myself and my vehicle. I believe this is a major safety concern because the engine can stall or catch fire without warning. I am requesting that NHTSA hold Hyundai accountable for failing to properly notify current owners and ensure compliance with the class action settlement. Desired Resolution: Require Hyundai to honor the warranty and cover my engine replacement in full. Investigate whether Hyundai is failing to properly notify owners about this critical software update. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

ENGINE

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. When they machined it, all the files they don't clean them good enough, so they go to one side and plug up the oil passages and it doesn't get oil. we were on the highway when this issue started and it lost power. The problem has not been solved because the Hyundai dealer and the corporate office did not want to help me with this issue. They claim that my title is salvaged but I contacted the DMV, and they confirmed that my title is clean and there is no issue. The second time they said the vehicle was used as a rental and that automatically disqualifies the vehicle's warranty. The vehicle has not been inspected. No warning at all until the day it happened. I just purchased this vehicle seven months ago for seven thousand dollars and this happened.

Dear NHTSA, My 2016 Hyundai Santa Fe Sport (VIN: [XXX] , 2.0L Theta II, 64,000 miles) suffered engine failure with knocking and power loss, matching NHTSA Recall #20V-746 (Hyundai #198). This defect risks stalling or fire, threatening my safety and others’. Hyundai Motor America and Hyundai of Tacoma (Tacoma, WA) refused repair, citing the rebuilt title, despite the factory defect. Recall #20V-746 addresses Theta II bearing wear. My vehicle’s symptoms align, yet the dealer denied service, claiming the title voids eligibility. Hyundai’s April 2025 email noted three unrelated recalls (turbo oil pipe, ECM update, hood latch) were completed but ignored #20V-746, redirecting me to the dealer without addressing the engine or title issue. I’ve called Hyundai (1-800-633-5151) and emailed multiple times since March 2025, receiving only generic responses. The dealer’s refusal and Hyundai’s inaction leave the vehicle inoperable, posing a ongoing safety hazard on the road. The rebuilt title should not exempt a factory defect tied to a safety recall. The low mileage (64,000) supports my claim. I haven’t obtained a diagnostic report but am willing to pay for one (~$100–$200) if required. Hyundai’s refusal to honor #20V-746 violates safety obligations. Please investigate Hyundai’s denial, confirm if the Knock Sensor Detection System was installed, and clarify if a rebuilt title excludes eligibility. I seek engine replacement per the recall or a clear explanation. This issue has caused significant financial and safety concerns, and I urge swift action.
