2023 Hyundai Santa Fe

Today, i received an extended warranty for my horn. There is a known issue with water getting into the horn and causing them to fail. Upon researching this, people have reported having their horns changed several times. This is a safety matter that an extended warranty is not fixing. Please enforce a recall so that this matter may be properly resolved. Canada has already issued a recall, I hope we can do the same. Thank you.

During on driving, engine stopped 3 or 4times since Jan/2025 Last time engine stopped yesterday around 6:30pm on 3/30/2026 at [XXX] between [XXX] and [XXX] in Los Angeles INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Oil pan leak.

Driving on sunny day, the fixed roof glass located between the windshield and sunroof exploded across the entire width of the glass insert with a very distracting noise.

Driving to work and a loud noise (pop) was heard and then I realized the sunroof had basically exploded. Glass was all over the car and all over myself. I immediately got off the road and turned on my hazard lights to assess the situation. This could have caused an accident had I not remained calm. Contacted dealership this morning. Waiting to hear back. No prior warning to this happening.

On March 4, 2026, at approximately 7:30 AM EST, while driving my 2023 Hyundai Santa Fe Limited on [XXX] , the vehicle experienced a sudden loss of propulsion while traveling at approximately 70 mph (posted speed limit). The vehicle would not accelerate or maintain speed and would not move forward when placed in drive, indicating a failure within the powertrain/transmission system. The vehicle is currently located at a Hyundai dealership and is available for inspection upon request. This incident created a significant safety risk, as I was traveling at highway speed in active traffic when the vehicle unexpectedly lost the ability to move under its own power. This placed me at risk of being rear-ended and made it difficult to safely maneuver out of traffic. The vehicle was inspected by a Hyundai dealership. Diagnostic trouble code P284001 (Shift Fork “D” Position) was identified, and I was informed the failure is transmission-related. The condition was reproduced by placing the vehicle in drive, at which point the vehicle would not move. The vehicle has been inspected by the dealership. The manufacturer has been notified but has not physically inspected the vehicle. No police or insurance inspection was involved. There were no warning lights, messages, or prior symptoms before the failure. The issue occurred suddenly without any indication of a problem.

While driving on the interstate at 70mph the vehicle’s fuel injectors failed causing the vehicle to lose power suddenly.

I have attached a photo since I couldn’t save it

The front rotors need machining every 10,000 to 15,000 miles. The rotors experience exceeding distortion due heating by the brake pads. When brakes are applied, there are large vibrations in the front suspension which inhibits braking. This is especially true when braking on wet pavement where stopping distances become unsafe.

I am submitting this complaint regarding a safety-related incident involving my 2023 Hyundai Santa Fe on February 14, 2026. While driving, the vehicle suddenly began to overheat, creating an immediate safety hazard. I was close to my home and was able to return there safely, but once parked, I observed coolant leaking from the front of the vehicle. Due to the risk of further overheating or engine failure, the vehicle was not drivable and had to be towed to a local Hyundai dealership. At the time of the incident, the vehicle had fewer than 38,000 miles and was purchased brand new. Despite this, the dealership informed me that the repair would not be covered under warranty, claiming the radiator damage was caused by “road debris.” However, they did not provide any evidence of an impact, puncture, or external damage. The only documentation offered was a video showing coolant spewing from the radiator after a technician inserted an object into the grille. This video does not demonstrate any pre‑existing road damage or confirm that debris caused the failure. I requested proof of actual damage multiple times, including photographs or inspection notes showing an impact point, but none was provided. Without verifiable evidence of external damage, I am concerned that this may represent a premature component failure or a potential safety defect in the cooling system. The sudden overheating while driving, combined with the lack of substantiated cause, raises significant safety concerns for me and potentially for other owners of this model. Thank you for your attention to this matter.

Needed to use horn in an emergency situation and that's when I found out my horn no longer works. 20,000 miles on 2023 Hyundai Santa Fe.

What component or system failed or malfunctioned, and is it available for inspection upon request? Horn How was your safety or the safety of others put at risk? My horn stopped working - cannot use it when driving to warn other drivers - safety issue Has the problem been reproduced or confirmed by a dealer or independent service center? Not reproduced, but dealership has confirmed the horn stopped working on three separate occasions. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Dealership - three times Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No. Hyundai dealership said my fuse blown on three separate occasions causing the horn to stop working. My horn stopped working a few months ago, then about a month ago and again last week - all due to blown fuses to which the dealership has no explanation.

Horn stopped working at 47,474 miles Check Tire Pressure System light is on, poor sensor at 45,650

Component/System Failure: The electronic throttle control system malfunctioned. The vehicle is reporting powertrain diagnostic trouble codes P2118 and P2101 through the Hyundai manufacturer mobile application (Bluelink), indicating an electronic throttle actuator / throttle control motor issue. The vehicle is available for inspection upon request. Safety Risk: This malfunction poses a safety risk because it can cause sudden loss of throttle response, reduced engine power (limp mode), or stalling while driving. Loss of throttle control increases the risk of a crash, especially in traffic or at intersections. Reproduction / Confirmation: The issue is ongoing. The check engine light remains illuminated and the fault codes continue to be displayed in the Hyundai mobile application. The problem has not yet been diagnosed by a dealership due to lack of immediate service availability. Inspections Performed: The vehicle has not yet been inspected by a Hyundai dealership or the manufacturer due to delayed service appointments. No inspections have been performed by police or insurance representatives. Warning Indicators / Symptoms: The check engine light illuminated and remains on. Diagnostic trouble codes P2118 and P2101 are displayed in the Hyundai mobile application. The warning light first appeared in late January 2026. Current Vehicle Condition: The vehicle is considered unsafe to drive due to the active electronic throttle control fault and risk of sudden loss of power.

2023 Hyundai Santa Fe Calligraphy repeated horn failures since purchasing vehicle new. Will be having 5th and 6th horns replaced with no effective remedy as vehicle has less than 11K miles on it and this urgently safety failure needs to be corrected. There is no warning of the horn failure until you need them to prevent an emergency/collision warning.

I stopped to fill the gas on my road trip and the gas panel would not open. As a single women driving alone this is not ideal. It took 45 min of continuous unlocking/locking with pushing to get it to pop open. There needs to be an alternative/emergency handle to pull so this does not happen again. I was standing in 32 degree weather the entire time! NOT SAFE

I have been fighting this issue now for 2 years, vibration while driving interstate speeds, especially right rear seat. I have had tires replaced twice trying to fix balance issue only to find out that one rim will not road force balance correctly, even with tire matched it only reduced road force balance to 20lbs (30lbs with out match). I have had it at discount tire and Gettel Hyundai of Lakewood ranch, FL several times. Hyundai sent a senior tech to look at tires, did not speak to me to get explanation of my concern, did a balance, got same numbers and said was good to go. My other 3 rims have a max road force of 12lbs without even being matched. This causes vibrations when driving, extra wear and force on the tire and is a safety concern. This rim is the issue and Hyundai refuses to fix it.

On 6/7/2023 with the original owner, the vehicle displayed code P1c2D03, according to carfax history the transmission was replaced 7/12/2023. I purchased the vehicle in May, 2025. In December, 2025, while driving to work I experienced intermittent loss of ability to accelerate, followed by the vehicle again displaying code P1C2D03 in the Bluelink app. The dealership performed a software update and told me to come get my car. On Monday, February 16, 2026, I started the vehicle and the dash displayed "Transmission error. Check transmission fluid immediately!", I again had it towed to the dealership where it has remained for the past three weeks. Now I have been called again to pick up the vehicle as the dealership cannot duplicate the error. At this time I am unsure if the service center actually checked the transmission fluid as the warning indicated should be done.

Both horns have failed for the second time since the vehicle was purchased new in November 2023 and is currently showing 25,000 miles. The first set was replaced under warranty at a Hyundai dealership approximately 1 year ago. Not having a functioning vehicle horn is a safety hazard that would fail annual vehicle safety inspection testing in my state.

Horn completely out, yes available. I was unable to warn another driver from entering my lane several times. Warn a pedestrian from stepping out into traffic. Confirmed by the dealer. The horn was Inspected replaced at my own cost on March 2025 by December 2025 the part is no longer operational. I asked the dealer to honor the warranty they declined saying the mileage was passed the warranty terms.
