2023 HYUNDAI SANTA FE Complaints

Every time it rains, one of the dual tone horns will fail. I have had the horn replaced 2 times. I am beginning to have a problem with the horn again after this last rain. It is a matter of time before it fails completely after a rain and becomes unusable. I feel this is a significant warning feature that MUST be reliable.

>>>>What component or system failed or malfunctioned, and is it available for inspection upon request? According to the Hyundai Bluelink app, the problem is caused by the battery management system, producing error code P0AA600. The result is that the vehicle does not get power to the wheels for a few seconds after giving it gas. It looks like the car is not moving, then it very slowly gains speed, followed by sudden acceleration. It is available for inspection upon request. >>>>How was your safety or the safety of others put at risk? It is a safety issue because other vehicles on the road may not be able to stop in time when the car pauses unexpectedly. Also the driver cannot predict when the car will surge forward. Merging or crossing traffic is very dangerous. >>>>Has the problem been reproduced or confirmed by a dealer or independent service center? The vehicle has been to the dealership two times to be inspected for this problem. They state that they cannot duplicate the issue but of course they can see the error code in the vehicle history. It is an issue that occurs at random; not every time the car is driven. It has occurred a total of 9 times during the 2,872 miles we have driven since we purchased it. >>>>Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Only the dealer has inspected the vehicle. Police, insurance, or others have not been involved. >>>>Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There is no warning that the error is going to occur. There is a warning when it is occurring, and the check engine light comes on. We purchased the car as new when it had 6,934 miles on it. It had been used as a demonstration car for the dealership. The error first occurred at about 7500 miles.

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.

Horn will not work. This occured on [XXX]. Appointment made with dealer. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Took vehicle to the dealership on Jan 3, 2025 for the 15k mile oil change. They informed me they completed the multi-point inspection, with no issues discovered. Jan 10, 2025 I attempted to us the horn and discovered it didn't work, so I immediately went back to the dealership and scheduled a service, to troubleshoot the horn. Jan 20, 2025 dealership discovered both horns were defective and replaced both. Very strange for both horns to die so early. ??

In January, 2024, my vehicle (2023 Hyundai Santa Fe) started shuddering when brakes were applied at high speed, on quick or hard stops, in stop and go traffic, and especially going downhill. I had only been driving the vehicle for about 5 months. I took the vehicle to an independent mechanic, who explained that my front rotors had burn spots. He recommended that I have them resurfaced. I did not want to pay for the problem to be fixed when I believed it was a factory defect and should be covered by warranty. I asked the Mission Hills Hyundai dealership Service Department to investigate and correct the problem, because I felt that my family's safety was jeopardized by faulty brakes. They showed me the burn spots on the front rotors and recommended resurfacing. They said I could wait for the pads to wear down and do the resurfacing at the same time as the pad replacement. Their estimate for resurfacing was higher than the one from my mechanic. I found a Hyundai Technical Service Bulletin, Number 23-BR-004H, which described the exact defects of my vehicle. I returned to the dealership with the TSB in February, 2024. They replaced the two defective front rotors and front disc pads at no charge. The shuddering was no longer evident, and I thought the problem was resolved. However, 10 months later in December, 2024, I once again experienced the shuddering while braking on the freeway while going downhill and when slowing for stops from high speed. Since I had been told that the new rotors and pads were covered by warranty for 5 years or 60,000 miles, I returned to the dealership on 1/16/25 and asked them to evaluate the brakes again. They said that the front rotors again had burn spots. They once again recommended resurfacing at a cost of $249. I reminded them that there was a warranty on the new parts, they claimed that the only warranty was for the original parts that had been replaced. They agreed to resurface no charge. Please investigate and respond to my complaint.

The sunroof glass violently shattered/exploded while driving the vehicle. The manufacturer claims the window meets current standards and is not defective. The curtain or fabric cover was extended covering the glass panel otherwise the driver would have been covered with broken glass.
