2023 HYUNDAI SANTA FE HYBRID

FUEL/PROPULSION SYSTEM

I am reporting a serious and recurring safety defect with my 2023 Hyundai Santa Fe Hybrid, purchased new in January 2024. The vehicle has suffered from over 30–40 sudden hybrid system failures, including loss of acceleration, “Stop Vehicle” warnings, and check engine lights. These incidents happen without warning, including while driving at legal speeds (40–70 mph), on residential streets and highways. Most recently, the car failed twice in two days, while my teenage son was driving within all road laws, including once with a friend in the car. The vehicle simply stopped accelerating in the middle of traffic, endangering them and everyone around them. These failures have happened at legal speeds ranging from 40–70 mph, on both residential roads and highways. There is no advance warning, just abrupt loss of power and sudden warning messages. We’ve taken the vehicle to the South Charlotte Hyundai dealership multiple times. Each time, they either reset the check engine light or replaced indicators: but never addressed the root hybrid system failure. We filed a lemon law case, and Hyundai responded with only a $2,000 offer including legal fees, requiring us to keep the dangerous vehicle. We rejected the offer. These failures have occurred with children and passengers in the car. We have documented as many incidents as we could, including photos, service records, and communication with Hyundai. The vehicle is available for inspection upon request. I no longer feel safe driving or allowing my family to drive this car. This is a critical hybrid system failure that continues to place lives at risk. I believe this may be part of a wider pattern affecting Hyundai hybrid vehicles, and I am pleading with the NHTSA to open an investigation before someone is seriously injured or worse.

I am reporting an URGENT REQUEST IMMEDIATE ACTION REGARDING A SERIOUS UNRESOLVED, RECURRING PUBLIC SAFETY ISSUE WITH MY VEHICLE. IT IS POTENTIALLY THE FAULT OF ALEXANDRIA HYUNDAI'S SERVICE DEPARTMENT (in Alexandria, VA) WHO HAD JUST SERVICED MY VEHICLE FOR WHAT SHOULD HAVE BEEN A ROUTINE SERVICING (on May 7). My car had a catastrophic and complete failure on a high speed highway (the car quickly decelerated) which represented an incredibly danger situation for myself and other drivers on the road. My car was purchased in 2023 and has 15,241 miles. It has been perfectly maintained. On [XXX], I was returning to my home in Virginia from Maryland on an 8 lane highway with a 55mph speed limit when I had a very dangerous complete failure of my car. Simultaneously, the car started bucking back, the speed was decelerating regardless of my pressing the accelerator to keep my speed the same as traffic, and I received a flashing large red message that said "CHECK HYBRID SYSTEM - STOP SAFELY." Fortunately I was in the far right lane and was able to veer it over to a narrow shoulder. It was 8pm and getting dark. After a short while, the car lost all power so I was on a narrow shoulder with no lights flashing anymore. I was in this dark car with a lot of traffic speeding my with my 2 dogs. I became incredibly stressed about how we were going to get home. I contacted AAA, a police officer and Uber Pet who worked together in this unsafe situation on the side of the highway to get myself and my dogs home into the Uber vehicle with only the front door opening (no power). It was over 2 hours before I was home safely It was incredibly stressful situation. The car was towed to Alexandria Hyundai and they dismissed the issue and fixed nothing. I contacted Hyundai customer service and asked for escalation and they have done nothing. I am restricted in my driving because of the severe safety risk but had to drive again on [XXX] and it occurred again on a highway INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U

I purchased a 2023 Hyundai Santa Fe Hybrid in November of 2023. Within a couple of months of purchase I had 2 incidents where without warning the car lost power and made a noise sounding like some sort of fan. One of the incidents was on [XXX] in Massachusetts, the heavy traffic cleared, I was in the fast lane, and the car would barely move. It was a safety issue as there was no place to go on the left side of the highway and traffic to my right had already picked up speed. After a minute or so the power again became available. This has happened to me several times but Hyundai has told me there is NO RECORD of this happening with my car model. On occasion I have my grandkids in the car and I am very concerned that Hyundai will not acknowledge this problem. By the way, it happened again this morning as I was pulling away from a Starbucks drive-up window. Can something be done about this? Hyundai should have records of my complaints as I visited the dealership where I bought the care and conversed via email with one of their service representatives that I do have a record of.
