We have had already had two issues with our Hyundai Santa Fe that we purchased new from a dealer on 5/21.The first malfunction happened on 7/23. While driving, we had several messages come across the dashboard warning that some sensors were not working properly. We then had the warning light, front collision light, the traction control light, the abs light, the auto hold and the emergency brake all light on the dash. We also lost the blind spot sensor on the side mirrors. Called the dealer and took the car in. Two days later was told it was a wheel sensor and all should be good. Then on 8/31, while merging onto a highway, I pressed the accelerator and although the engine revved, the car did not increase in speed. Luckily the car behind me was able to swing around me and I put on my hazards and pulled to side of the road. I turned the car off, restarted it and pulled out. …
The horns stopped working, and this is a safety item since it's the only way to notify another vehicle or pedestrian if they will be hit by my car. Another day, a car came out of the parking lot and almost hit my car. I was only able to avoid that accident because I reversed quickly. I took my car to the dealership, and it was confirmed that the horns are not working. To fix this issue, I need to replace them. But since my car is out of warranty, I will need to pay for this service. On 07/14/2025, I called Hyundai (Case number 4117-7538) to request the application of an extended warranty that they started to offer for the 2021-2025 model year Elantra (Z03). Since my car is the 2022 model year Santa Fe, they did not accept my request. I noticed that on several websites, Hyundai car owners are complaining about their car horns. …

I did a navigation update as requested by the infotainment system on the Hyundai. After the update, the air conditioner would not turn on when the ac button was depressed . I took the vehicle to my local Hyundai dealer and they found the ac blower and ac button working intermittently. After further inspection, the mechanic found the multi fuses that sit on the PCB bloc had one burnt fuse that did not blow and was still hot and the PCB block had melted around where the fuse connected to it. ( Hyundai stated that they required the damaged PCB fuse, the PCB block and the harness). I'm concerned that the electrical short discovered by the Hyundai mechanic could have progress and burnt my car or my house since I keep my car in the garage. The Mechanic working for the Hyundai dealer found the burnt fuses and PCB block and kept them after replacing them with new parts. …
While driving to work, the rear driver-side window suddenly fell down into the door without warning. The power window/regulator system appears to have failed. The window would not stay up or operate normally afterward. The failed component is available for inspection upon request. This created a safety concern because the vehicle could not be secured, outside air/noise entered the vehicle while driving, and rain/debris could enter the passenger compartment. It also created a distraction while driving because the sudden window drop was unexpected. There were no warning lights, dashboard messages, or prior symptoms before the failure. The issue has not yet been confirmed by a dealer or independent repair shop. The vehicle/component has not yet been inspected by the manufacturer, police, insurance, or others. …
The back doors should unlock when the SUV is put in park or the motor is turned off. However, it does not unlock over 25% of the time. This means the back doors can not be opened from the outside or inside. People in the back cannot get out unless the doors are manually unlocked from the control panel in the front. This is a real safety issue if there was an accident and the people are trapped in the car. This issue has been reported to the dealer for almost two years. They have not been able to fix the issue. I have reported this problem to Hyundai National Consumer Affairs (case # [redacted]) asking for their help. I ask if this falls under the lemon law since it can not be fixed and is safety issue. I was informed they could not help me.
