2023 Hyundai Santa Fe

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.

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.

1. The factory-supplied scissor-type jack that came with my 2023 Hyundai Santa Fe failed. While changing a flat tire on the side of the road, the jack collapsed three times and could not hold the vehicle. Yes, the jack is still available for inspection. I have it in my possession and have provided photographs of the jack, its capacity label, and the incident location as evidence. 2. My safety was put at serious risk. The vehicle fell off the jack three times while I was attempting to change the tire on the road. The car remained on the ground without a tire until roadside assistance arrived. If I or a family member had been under or near the vehicle when it fell, we could have been seriously injured or killed. My wife and three toddlers travel in this vehicle, making this a major safety concern for our family. 3. No. Rosen Hyundai dismissed my concern. Service Manager Jeff Bravieri claimed the jack is rated for 3 tons (6,000 lbs) and blamed user error. But my photo shows the jack's label states 1,200 kg (2,645 lbs). The road was flat. The dealership dismissed my safety concern and refused to replace the jack unless I paid for it. They have not inspected the jack despite my request until the involvement of Hyundai Motor America. 4. Not sure, that vehicle and jack have been inspected by the manufacturer, police, or insurance representatives. However, manager later agreed to inspect it and instead blamed user error. I am reporting this directly to NHTSA because the dealership and Hyundai have not taken this safety defect seriously. 5. No. No warning lights or signs. The jack looked normal. It failed the first time when I used it in an emergency situation. 6. The jack label says 1,200 kg (2,645 lbs). My vehicle weight is 1,724 kg (3,801 lbs) . The jack is under-rated and unsafe. It failed on a flat road. The dealer ignored the evidence. I fear this could happen to others and cause serious injury or death.

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.

Total horn failure, both horns. Took vehicle to the dealership, diagnosed both horns need to be replaced. None in stock. Horns ordered , no dates known by Hyundai when they will be in stock. Hyundai admits it h. Known with many models Driving a car in Buffalo NYwith. Out a horn driving a vehicle,r Nissan , is VERY DANGEROUS and scary. I do not think that Hyundai is taking this issue seriously and they need a recall and plan to fix this problem.

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.
