2025 Hyundai Santa Fe problems

Filed Oct 30, 2026 · Acceleration, Driver assistance · CA

On three occasions while Highway Driving Assist / Smart Cruise Control was engaged, my 2025 Hyundai Santa Fe Hybrid did not slow down for the vehicle ahead and continued at its set speed. I had to brake manually to avoid a collision. Dates and conditions: UNKNOWN exact dates. All three occurred within the past several weeks. Warning lamps or messages: UNKNOWN. I did not notice a warning before the system failed to slow down. Inspection: The vehicle has not yet been inspected for this problem. I have reported it to Westlake Hyundai in Thousand Oaks, CA, and it has a service appointment scheduled. It has not been inspected by the manufacturer, police, or insurance. The vehicle also has other ongoing issues, including the brake pedal sticking at startup, two no-start events requiring roadside assistance, and intermittent electrical problems. I am concerned this is a safety defect that could cause a rear-end collision.

2025 Hyundai Santa Fe - The sound for the blinkers, rear-view camera alerts, and radio sounds has gone out 2 times, once in XXX and then on XXX. This is a safety issue. I have had issues with an electrical battery drain with the key fob antenna being one of issues draining the battery and replaced in XXX. After the sound went out on XXX, I did not drive the vehicle for 1 day, then went to get into the vehicle on Wednesday, XXX and the vehicle was dead. No lights were on, it would not unlock. I missed the scheduled service appointment I had on the XXX due to the dead battery. The car had sat unused for less than 24 hours. I had to call Hyundai roadside assistance for them to jump the car off and tow it to the dealership yesterday afternoon. The battery drain started happening at 700 miles on the car, where I jumped it off myself, and continued to happen every month or two. I kept jumping it off and taking it to the dealership to let them know what was going on. Sometimes, they would investigate it, and sometimes nothing would get done about it. I have had to jump this vehicle off myself at least 6 times since XXX. Yesterday, I just called roadside assistance. There is clearly an electrical drain on the car battery somewhere in this vehicle. XXX, the car was located in [XXX] on a vacation and started having shuttering and engine light came on. This was fixed on XXX by replacing #4 fuel injector prior to 30,000 miles. This is not a reliable vehicle, or safe. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

with not warming the vehicle would not start using the standard FOB. It would not be recognized. Fortunately, we had an alternative Digital Card (which is NOT standard equipment) that allowed us to start and drive the vehicle. Upon calling Hyundai support we were instructed to take the vehicle to the nearest Hyundai dealership for diagnosis. The diagnosis was a failed BDC (Body Domain Controller). This part took a week to arrive at the dealership and subsequent repairs were made. The dealership indicated that they had seen this problem before, but no service advisories from Hyundai were available for this issue. I have asked Hyundai for an explanation and nothing has been forthcoming. My primary issue with this problem is that if I had not acquired a digital card, at an additional cost of approximately $200, we would have been stranded, with no manner in which to start or drive the vehicle. There were no indications of a problem, no alerts in car, and no alerts via the My Hyundai web site via the internal diagnostics. The BDC just failed, with no explanation. Without any type of explanation or diagnostic information, who knows if or when this could occur again, and where.

the ongoing safety defect affecting my leased 2025 Hyundai Santa Fe. This summarizes the facts as discussed, the danger this defect presents, and the urgent need for resolution. Summary of the Defect Since leasing the vehicle, it has intermittently and without warning decelerated to a complete stop (0 MPH) while driving, regardless of the speed at which I am traveling — including at approximately 30 MPH on local roads and at approximately 65 MPH on I-95. The specific facts of this defect are as follows: The vehicle decelerates to a full stop within approximately 5-10 seconds of the malfunction beginning, with no advance warning. After the vehicle stops, attempting to accelerate again takes approximately 30-45 seconds before the vehicle begins to move, and it does so only slowly. When this occurs, the vehicle beeps and a flashing green “OFF LIMITS” light appears. No check engine light or other diagnostic warning is triggered at any point. This has occurred approximately 25 times since I leased the vehicle. On the last three occasions I reported this, Hyundai/dealership personnel drove the vehicle and were unable to duplicate the problem. As I have repeatedly explained, the defect occurs intermittently and unpredictably, so this is not evidence the problem does not exist. The Danger This Defect Presents I want to be direct about the severity of this situation. A vehicle that decelerates to a complete stop without warning — whether on a local road or on a highway at 65 MPH — creates an immediate risk of a rear-end collision, a multi-vehicle accident, or worse. The fact that the vehicle then takes 30-45 seconds to regain even slow movement compounds this danger, particularly in moving traffic. This is not a comfort or inconvenience issue; it is a significant, stressful, and potentially deadly safety defect, both for me and for any passengers in my vehicle, as well as for other drivers on the road.

the federal safety agency Vehicle Safety Complaint My 2025 Hyundai Santa Fe has a recurring problem when starting the vehicle. When I start the vehicle, the engine jumps abnormally. I have taken the vehicle to a Hyundai dealership multiple times specifically because of this problem. The condition continues to occur, but I have repeatedly been told that the dealership cannot find anything wrong and that they have to wait for a diagnostic code to appear before they can determine the cause. The vehicle has now developed an additional symptom. When I turn the vehicle off, it sometimes makes an abnormal prolonged gurgling/squeaking-type noise that continues for approximately 3-4 seconds. This shutdown noise is new and is occurring in addition to the recurring engine jumping during startup. No cause has been identified or repaired despite multiple dealership visits. I am concerned that an unidentified engine/powertrain problem is continuing and appears to be developing additional symptoms while I continue operating the vehicle. The vehicle remains available for inspection. I have also experienced problems with both middle-row seats not properly retracting/folding. I reported the problem to the dealership, but only one side was addressed. A component from the back of one seat has also detached. The detached component and vehicle remain available for inspection. I am reporting these conditions because they have continued despite repeated attempts to obtain diagnosis and repair. I do not know the underlying cause, and the dealership has not identified one. Its becoming worse then before so something is wrong.

Pirelli Scorpion 255/45 R20 I am filing this complaint regarding a serious and unacceptable defect with my Pirelli tires. To date, two of the four tires have proven to be defective. In both instances, the defect was not readily apparent while the tires were mounted on the vehicle. The problem was discovered only when a qualified tire technician attempted to remove the tires from their rims. In both cases, the tire structure collapsed during removal. This is extremely concerning. A tire should not collapse or fail structurally simply because a trained tire technician is removing it from the wheel. The fact that this has now occurred with two out of four tires strongly suggests that this is not an isolated incident. I have also researched complaints filed with the federal safety agency and have found numerous complaints involving Pirelli tires and sidewall failures, including sidewall bulges, blowouts, tread separation, and other structural failures. My research indicates that there are at least 15 complaints specifically involving the sidewall giving way. the federal safety agency states that consumer complaints are used to identify potential safety-defect trends. There are also recent the federal safety agency complaints involving Pirelli tires reporting sidewall bulges and failures, including complaints involving relatively new tires. Given that 50% of my four tires have now exhibited a serious structural failure, I am extremely concerned about the safety and reliability of the remaining two tires. I do not believe I should be expected to continue using tires that may contain the same defect. I am requesting that Pirelli: Immediately investigate all four tires, including the two that have already failed. Provide a written explanation as to why these tires collapsed during professional removal from the rims. Determine whether this represents a manufacturing or structural defect. Replace all four tires at no cost to me, rather than requiring me to wait for additional

ON 3 separate occasions the vehicle has suddenly quit going.twice going through an intersection after taking off. the third time going up hill near my house. the car would only go 10 mph. A message would come up on the dash that reads " transmission system error, Check transmission oil immediately. That was not the problem. The Hyundai dealership performed a recall update on the computer the first time.but that didn't solve the problem as a week later the same thing happened .Again the car was towed to the dealership. this time another transmission service was performed according to a tech line information. after retrieving my car from the dealership I drove it for less than a week and the same thing happened. The car was towed back to the dealership again.Now the dealership says they can't do any repairs as the computer will not store any malfunction codes so they will know what to repair. I have been in contact with Hyundai Motor America and a case file has been established. " 43176412 ". Hyundai will not accept any responsibility for placing a computer in a car that will not retain a MIL code. Hyundai now tells me they have done all they can and for me to get my car from the dealership and drive it. That is ridiculous. Hyundai wants me to put myself in danger of having a wreck because the car loses power in front of traffic behind me. People start slamming on brakes to keep from hitting me and blowing their horns.I'm also afraid of some loose cannon out there having road rage at me because I can't get out of the way. As for the car and Hyundai , no mention of the shortcomings of the computer was mentioned until the 3rd time the car was towed back to the dealership. Also, there is some type of serious problem with the transmission which Hyundai is failing to be concerned with . This is a dangerous situation. do I need to be seriously injured or worse before Hyundai addresses this issue ?
