2022 HYUNDAI SANTA FE Complaints

My passenger's front door side vent window glass shattered unexplainably while I was making a left hand turn at 15 mph. This occurred at 7:25am in the morning after pulling my car out of my garage and driving about 1/3 mile before the unexplained glass explosion/shattering. The sound made was a loud bang/pop. Air temperature was around 68 degrees, no air conditioning was being used at the time. No other cars or pedestrians were around when it occurred. I inspected the glass and it does not appear as if there was any possibility it was caused by a rock or a projectile such as a bullet or bb gun. As mentioned the component that failed was a fixed vent window that does not open. Fortunately no passengers were in the car when the glass shattered. It has not been inspected since insurance will not cover the cost of the glass replacement. (Safelite glass to replace for $346.00 (my insurance deductible exceeds that amount). No warning signs before it occurred. (Possible manufacturing defect -impurities in glass? I don't think it was body flex or vibration which may have caused the explosion as I was driving only 15mph. I don't believe it is attributable to thermal stress either -due to no variation between internal and external air temperature)

Vehicle: 2022 Hyundai Santa Fe | Current Mileage: 140,000 Description of Safety Defect: While operating a 2022 Hyundai Santa Fe at speed, the vehicle suffered a sudden, complete, and catastrophic loss of motive power in the middle of a live, active roadway without any prior warning or dashboard indicator lights. The transmission abruptly dropped out of gear and the engine shut down entirely, trapping the driver and three young children in active traffic and creating an immediate, life-threatening highway safety hazard. The vehicle was towed to Sport Durst Hyundai in Durham, NC, where technicians confirmed a total internal transmission failure where the gears fail to engage. This exact mechanical failure mechanism directly mirrors the severe engineering defect detailed in NHTSA Campaign Number 22V746000 (Hyundai Safety Recall 236) for electric oil pump failures causing a sudden loss of drive power. Hyundai Motor America Corporate Case Management has issued a flat denial of all safety and goodwill repair coverage based strictly on the vehicle's 140,000 miles, claiming that mileage absolves them of product liability for a catastrophic drivetrain safety defect that endangered three young children. Furthermore, the franchise dealership is actively withholding the GDS diagnostic failure scan codes from the consumer, calling them "internal documents" to actively suppress federal evidence of this safety failure. Further, the authorized Hyundai dealership engaged in deceptive practices by refusing to put anything in writing, and refusing my request for any diagnostic information, including any report indicating diagnostic error codes, technician summary, etc.

Beginning on 04/17/2026, my vehicle began displaying multiple safety-related dashboard warnings simultaneously, accompanied by audible alerts. The warnings included the Forward Collision Safety System, Blind-Spot Monitoring, Electronic Parking Brake (EPB), Stability and Traction Control, Lane Keep Assist, and AUTO HOLD — all activating at the same time. These warnings reappeared on several occasions and were photographed with date and location data embedded in each image. My vehicle was brought to Burlington Hyundai dealership, where a repair order was opened and a loaner was provided. The car was returned without the issue being fixed. Within days, the same warnings reappeared and the situation worsened. On multiple occasions, the engine shut off completely and the transmission shifted into neutral on its own while my vehicle was being driven at approximately 20 to 40 mph. On at least one occasion, the parking brake engaged automatically without any input from the driver. A dashboard photo clearly documents the message "Engine Off! Shift to N, then start engine." These failures are a serious danger to everyone on the road. When the engine shuts off while driving, normal steering and braking ability is lost. When the parking brake engaged on its own, the car stopped abruptly with no warning. Any one of these incidents could have caused a serious accident or injury. My vehicle was returned to the dealership for a second repair visit and a second loaner was provided. The dealership confirmed via text that the car was still in the shop but never followed up with a diagnosis or timeline. When the dealership was called directly, no update was provided. As of 06/04/2026, my vehicle has been at the dealership for at least 30 days across two visits — 11 days for the first and at least 19 days for the second — with no confirmed root cause, no completed repair, and no clear communication.

The contact owns a 2022 Hyundai Santa Fe. The contact stated that while in reverse (R) on several occasions the rearview camera went completely white and the camera did not come on at all. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 92,500.

I PUT MY VEHICLE IN PARK AND VEHICLE CONTINUED TO MOVE, IT MOVED OVER A CURB AND INTO A WALL. I BROUGHT VEHICLE TO DEALERSHIP NEXT DAY AND THEY STATED IT WAS A GEAR CONTROL ISSUE AND NEEDED TO BE REPLACED. I BROUGHT THE VEHICLE TO GET AN ESTIMATE FOR REPAIRS AND ESTIMATE IS NEAR $7000. DEALERSHIP SAID THE PART IS NOT UNDER WARRANTY AND NO RECALLS. THIS IS A SAFETY CONCERN. VEHICLE HAS NOT BEEN CHECKED BY MANUFACTURE, POLICE OR INSURANCE AS OF YET NO WARNING LAMPS OR MESSAGES WARNED ME OF A POSSIBLE GEAR FAILURE. I HAVE READ ONLINE OF OTHER PEOPLE HAVING THIS SAME ISSUE WITH HYUNDAI SANTA FE

Engine light for car read codes PO 304 303 420 prior to sale of car per code read out taken when engine light went off shortly after my purchase. Not addressed prior to sale. Codes read and called to dealership. Car taken for service. Reported fuel smell, exceleration issues, short stallings. Same codes. Stated car was " fine." Drivable. Asked for brakes/ rotors to be checked. No documented brake service given. Stated they were "fine." Taken to local brake place next day that confirmed brake rotors needed repair. Car returned after began sputtering. Reported as fuel injector failure. A known issue with this makr and model that shown codes point to that were given to, and read at service center by mechanic at dealership twice. They did not mention replacing catalytic converter, that is damaged from injectors and an emissions issue at time of call regarding repair report. No brake report or inspection requested multiple times to be checked. Did not follow correct protocol to ensure engine was clear of fuel sprayed by injectors into pistons, intake valves, ect. They placed my self at risk for engine fire, sudden car failure. Consistently mislead and failed to do proper reseach and care regarding car issues and hazards it presented. Being a known issue with this make and model it was a failure to inspect for issue. An emissions failure and violation to allow a damaged catalytic converter to be on road. This issue with the car is in class actionable suit. It is not on the recall list. As it damages the whole car systemi including emissions, it should be forced to be on the recall list so dealerships cannot allow potential harm to their customers as well as violating emission laws.

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 suspected failed component is the rear driver-side power window regulator or related window mechanism. Cause is unknown.

This vehicle has experienced: • Multiple roadside breakdowns • Three fuel injector system failures • 2 complete transmission failures and replacements • Loss of propulsion • Fuel and chemical odor safety risks • A cumulative total of over 60 days out of service, currently at dealer since 4-15-26.

when vehicle accelerates from stopping position motor immediately increases rpm's from 700 to about 4,000 and increases and decreases with jerking motion. sometimes much difficulty controlling speed and controlling car when there are approaching vehicles. the transmission does not perform safely there is the same problem when passing other vehicles and travelling uphill , sometimes 50 to 75 mph. the selling dealer informed me this may be this transmission's way of learning how to accelerate.I don't believe this. I am [XXX] old, never a ticket with two safety classes in my first 30 years of driving heavy vehicles for my employer. the selling dealer was unable to completely reproduce problem. I have this problem when vehicle is first activated in the morning as I begin driving also. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Fuel injector failed the entire engine on my 2022 Santa Fe had to be completely replaced. The dealership put in a new engine. Santa Fe is only four years old. That is highly unusual.
