2020 Hyundai Santa Fe

I drove my car from for about an hour to my destination. I get to my destination and park and the car starts smoking lightly from under the hood and then increases. I was still sitting in the car when I was told my car was on fire. It went from a little smoke to a full blown fire in a couple of minutes. I got out the car and within minutes the front of the car caught fire and blew up. The car has been inspected by insurance. There were no warnings prior to this happening. I could have been serious injured or possibly killed. I am currently experiencing PTSD from this event. My son was just in my car previously. I am have this happened when I was there alone. I see that there are certain years that have been affected by fire, but the 2020 should be involved.

At approximately 122,000 miles, my 2020 Hyundai Santa Fe experienced a serious engine malfunction while I was driving on the highway. The check engine light suddenly illuminated and the vehicle began thrusting/jerking forward unexpectedly. We immediately took action to exit the highway and were able to get off the highway, but the engine died before we could fully stop the vehicle. This created a serious safety risk because the unexpected jerking and subsequent loss of engine power occurred while traveling at highway speeds and could have resulted in loss of control or a collision. The vehicle was towed to a local independent mechanic. After inspecting it, the mechanic stated that the engine needed to be replaced and recommended taking it to a Hyundai dealership because of the continuing issues associated with the Theta II engine. The vehicle was then towed to the Hyundai dealership. The Hyundai dealership inspected the vehicle and determined that cylinders 2 and 4 were not firing and recommended replacing the valve shaft. We requested a complete engine replacement. Hyundai initially offered a 50/50 split of the repair cost, but after we requested an engine replacement, Hyundai declined and instead offered a 70/30 cost split. There was also a previous documented concern regarding increased oil consumption, as noted in an earlier oil-consumption report. The vehicle has been inspected by both an independent mechanic and a Hyundai dealership. The vehicle and engine components are available for inspection upon request. No police or insurance inspection was performed, to my knowledge.

Hyundai Motor America & Wallace Hyundai of StuartVEHICLE: 2020 Hyundai Santa Fe (2.4L Theta II GDI Engine)VIN: 5NMS23AD5LH181669INCIDENT MILEAGE: 181,000 MiHYUNDAI CASE NUMBER: 42981944SECTION 1: CATASTROPHIC INTERSTATE SAFETY INCIDENTOn July 16, 2026, while navigating heavy, high-speed traffic on Interstate 95 (I-95) at approximately 80 to 85 MPH, my vehicle suffered an un-commanded, catastrophic mechanical engine seizure. The vehicle instantly dropped from highway speeds down to a 21 MPH "limp mode," creating an immediate multi-car pile-up hazard on a major interstate. Physical inspection immediately after the failure proved that the engine oil level was completely full. The internal components catastrophically failed due to a documented, systemic factory defect involving premature rod bearing failure and oil starvation mechanisms, entirely unrelated to consumer maintenance.SECTION 2: PRIOR SAFETY COMPLAINTS & DOCUMENTED TIMELINEHyundai Motor America has intentionally forced me to operate a known, life-threatening safety hazard for 17 months, during which I drove an additional 31,000 miles under extreme duress. I filed formal oil consumption complaints with Hyundai Corporate every three to four months. I was forced to manually replenish the engine oil every 1,000 miles due to excessive oil loss.Specific safety reports detailing hazardous engine behavior were formally logged with Hyundai on November 25, 2025, and again in April 2026. Rather than remediating the vehicle, Hyundai corporate claims adjusters and dealership supervisors ignored these warning tracks, effectively throwing a consumer out into active traffic in an unsafe, defective vehicle.SECTION 3: AUTOMATIC SHUTDOWN TRAUMA & ACCIDENT RISKThe manufacturing defects caused an intermittent, un-commanded automatic The manufacturing defects caused an intermittent, un-commanded automatic engine shutdown condition. On 5 to 10 separate occasions while stationary at active traffic lights, the vehicle stalled10times

My car is consuming an immense amount of oil, the manufacturer recommends oil changes every 7,500 miles, I get an oil change less than 3,000 miles and on my last oil change i was told that there are oil shavings in my oil filter. I just got the SC9C2 update and now my engine is knocking. Car drives super rough and has signs of rod bearing failure. My engine is the Theta II 2.4GDI, a class action lawsuit was filed against Hyundai but my car wasn't included. I don't understand how Hyundai can know about this issue with this engine and not cover replacement. A car should at the very least last for the life of the loan, I am going to end up with no car and still making payments.

2020 HYUNDAI SANTA FE SEL WITH 2.4L THETA II ENGINE EXPERIENCES SEVERE OIL CONSUMPTION AND REPEATED ENGINE STALLING DURING NORMAL OPERATION. THE VEHICLE HAS A DOCUMENTED HISTORY OF REPEATED LOW-OIL CONDITIONS DESPITE REGULAR OIL SERVICE. THE PROBLEM PROGRESSED TO THE ENGINE REPEATEDLY STALLING WHEN RETURNING TO IDLE. WHEN BRAKING TO A STOP OR WHILE STOPPED AT A TRAFFIC LIGHT OR STOP SIGN, THE ENGINE MAY STALL UNLESS THE DRIVER MAINTAINS ADDITIONAL THROTTLE. THIS CREATES A SAFETY CONCERN BECAUSE THE ENGINE CAN SHUT OFF DURING NORMAL TRAFFIC OPERATION. THE VEHICLE WAS PRESENTED TO CENTEREACH HYUNDAI FOR DIAGNOSIS. ACCORDING TO THE HYUNDAI SERVICE ADVISOR, THE DEALERSHIP FOUND THE ENGINE WITH VERY LITTLE/NEARLY NO ENGINE OIL DESPITE THE VEHICLE HAVING TRAVELED LESS THAN APPROXIMATELY 500 MILES SINCE ITS MOST RECENT OIL SERVICE/TOP-OFF. THE HYUNDAI TECHNICIAN REPORTEDLY SUSPECTS THAT THE ENGINE TIMING MAY HAVE JUMPED AND THAT THIS CONDITION MAY BE RELATED TO THE LOW-OIL CONDITION AND MAY EXPLAIN THE ENGINE STALLING. HYUNDAI HAS DIRECTED THAT AN OIL-CONSUMPTION TEST BE PERFORMED. THE INITIAL OIL SERVICE/ENGINE-FLUSH PROCEDURE HAS BEEN AUTHORIZED BY THE OWNER AT APPROXIMATELY $400. THE PROCEDURE THEN CONTEMPLATES APPROXIMATELY 1,000 MILES OF ADDITIONAL VEHICLE OPERATION TO MEASURE OIL CONSUMPTION. THIS CREATES AN ADDITIONAL SAFETY CONCERN BECAUSE THE VEHICLE BEING REQUIRED TO ACCUMULATE APPROXIMATELY 1,000 MILES IS THE SAME VEHICLE THAT HAS BEEN REPORTED TO REPEATEDLY STALL AT IDLE AND FOR WHICH THE HYUNDAI TECHNICIAN REPORTEDLY SUSPECTS A TIMING PROBLEM. THE OWNER HAS REQUESTED THAT HYUNDAI DOCUMENT WHETHER THE VEHICLE HAS BEEN EVALUATED FOR THE STALLING CONDITION AND WHETHER HYUNDAI CONSIDERS IT APPROPRIATE TO OPERATE FOR THE REQUIRED MILEAGE-ACCUMULATION TEST. HYUNDAI MOTOR AMERICA CASE NUMBER: 43164946. VIN: 5NMS3CAD4LH173916.

The multifunction/turn signal switch in my Hyundai has failed and causes the left turn signal to operate intermittently. While driving, I am unable to reliably activate the left turn signal when making a left turn or changing lanes. The signal may fail to engage when the turn signal lever is operated, requiring repeated attempts to activate it. College Station Hyundai inspected the vehicle and diagnosed the multifunction switch as the failed component requiring replacement. The replacement component has been identified as Hyundai part number 93400-S1750. I consider this a significant safety concern because the failure prevents me from reliably signaling my intention to turn or change lanes to other motorists. The malfunction occurs during normal operation of the vehicle and creates the risk that surrounding drivers will not know that I intend to turn or change lanes. The vehicle currently has approximately 86,611 miles. I reported the issue to Hyundai Motor America and requested assistance because this is a safety-critical component. Hyundai declined my request because the vehicle is outside the warranty period. I am submitting this complaint because I believe the premature failure of a component necessary for the reliable operation of the vehicle's turn signals may constitute a safety-related defect, and I am requesting that NHTSA document and evaluate this failure.
