2019 Hyundai Santa Fe Xl

The contact owns a 2019 Hyundai Santa Fe XL. The contact stated that while driving at an undisclosed speed, there was an abnormal sound coming from the vehicle. The vehicle was driven to the shoulder of the road, and the contact listened for the abnormal sound. The abnormal sound was persistent. The vehicle was driven to the residence. The contact stated that the check engine warning light was illuminated, and the engine seized. The vehicle was towed to an independent mechanic, where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. In addition, the contact stated that a year prior, an unknown recall notification was received for a special engine warranty program. The vehicle was taken to the dealer, where it was diagnosed with a timing chain failure. The contact was informed that the timing chain needed to be replaced. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 80,000.

Our vehicle had 145,000 miles and all maintenance and repairs performed at Hyundai dealerships. Joseph Airport Hyundai in Vandalia, Ohio replaced the timing chain at a cost of $3500. After replacing the timing chain our vehicle began consuming large amounts of oil (9 quarts over 5000 miles). The dealership has tried several repairs and the vehicle still continues to consume the same amount of oil. We now have 160,000 miles on the vehicle and need to always carry a 5 quart container of oil so it doesn't run low. This never happened until we had the timing chain replaced.

On [XXX], the check engine light came on in my 2019 Hyundai Santa Fe XL. The dealership diagnosed a complete engine failure requiring full replacement. The vehicle has only 54,000 miles. The dealer submitted a warranty claim to Hyundai, but Hyundai denied it because I could not provide receipts for every oil change, despite the fact that the vehicle has been responsibly maintained. An appeal to Hyundai’s goodwill department was also denied. This sudden and premature engine failure poses a serious safety risk. Engines from this generation (Lambda II / GDI family) are known to suffer from rod bearing failure, oil consumption, and sudden seizure. If this failure had occurred at highway speed, it could have led to loss of power, stalling, or an accident. Numerous owners have reported similar engine failures in 2016–2019 Santa Fe models at relatively low mileage, and Hyundai has already issued recalls and warranty extensions for related engines. This indicates a potential widespread defect that may not be adequately addressed. Requested Action: I am asking NHTSA to investigate Hyundai’s engine failures in the 2019 Santa Fe XL, review Hyundai’s denial of warranty coverage for vehicles experiencing these failures, and consider expanding existing recalls/warranty extensions to include this model.

Sun roof exploded. We were driving down the highway and heard a loud crack. The sun roof exploded on us and there was shattered glass from the front to the back of the vehicle. There is no evidence of anything hitting the glass and there was no weather that could have caused the damage. Cloudy skies but 50 degrees Fahrenheit. Absolutely no way to explain the incident. Both my husband and I received small cuts trying to remove the glass. Our dog was in the vehicle and luckily was not harmed in the event.
