2023 HYUNDAI SANTA FE Complaints

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

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.

Own a 2023 Hyundai Santa Fe Hybrid and have experienced the following issues over the past year and a half. Beginning after maybe 40,000 miles we pulled out onto a roadway and the engine immediately lost power and started flashing a glaring red warning that the hybrid system was failing and to pull over. We luckily were able to and turned the car off and waited. I tried to turn it on and it came back to life as if there was never an issue? We drove off. it left no warning code or did not update my Bluelink App. I took it to the dealership and they could not find any issues. Fast forward another 5 or 6 months and it happens again. Take it to the dealer and they keep it a week to go over it but still nothing. Within a week of getting it back it happens again and this time I am videoing it happening to me. Back to the dealer and provide the video because again the car did not log the event nor did it update my app. They hold it again for a week and try different things. They still cannot figure it out and I get it back.... it happens again.... This time the dealership was able to come up with an answer and that the oil level was too high. I got the car back and it seemed to work. Probably now 6 months go by and then this week I drive over to Jacksonville (5 hr drive) and visit. Again the car scares us on the highway and I have to pull over. Havea friend meet us with tools and we jack up the car and let out enough engine oil to insure we can read between the two marks on the dipstick. We drive off but the engine keeps hestitating and we almost make it back before it completly shuts down. We tow it to the Dealer in Jacksonville. They call the next morning like they can't find anything wrong! I explain everything and remind I don't tow cars for fun - something is wrong with the car and it is leaving us vulnerable and worst is it is not leaving any codes. Not sure but I have lost faith in Hyundai

While on the highway my car lost power, gradually slowing down to a stall. I was able to safely park on the side of the road. I got the car to a nearby dealership that kept it for 10 days. The dealership said that the problem was code P2118 (Throttle Actuator Control Motor Current Range/Performance) that the air "flap" was frozen stuck shut and the engine was disabled on the freeway in order to prevent damage. The resolution was "waited for it to thaw and cleared the code". The dealer has a service bulletin and a software update but it did not resolve the safety issue. I've noticed hesitation when accelerating the car from a dead stop as well, which started last year.

The horn stops working which is a safety hazard in case someone is backing into you, etc. This horn has stop working 4 times and had to be replaced.

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.

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.

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.
