Subject: Formal Dispute: Warranty Breach and Failure to Repair – 2023 Hyundai Santa Fe Timeline & Facts:11/2/25 (~52,000 miles): I officially reported an intermittent loss of power and severe engine revving (up to 7,000 RPM). This created a severe safety hazard when merging and accelerating from an idle stop.3/28/26 (Under 60k miles): After months of diagnostic delays, Hyundai confirmed the Dual-Clutch Transmission (DCT) needed replacement under the 60,000-mile warranty. A Hyundai Case Manager tracked the issue.Service Delay: Hyundai delayed repairs due to a lack of loaner vehicles, which were grounded for recall updates. Commuting pushed my mileage to 60,218. The Case Manager assured me coverage was locked in because the defect was documented before 60,000 miles.4/8/26: Due to corporate protocol, they ordered a valve body installation instead of a new transmission.8/11/26: The valve body failed. Hyundai delaership resubmitted the transmission replacement request. Corporate denied 100% coverage because the odometer was now over 60,000 miles (60,218). They are offering only 80%, leaving me with a $1,000 plus out-of-pocket expense.Legal & Contractual Position:Hyundai is contractually and legally obligated to cover 100% of this replacement. Under federal and state consumer protection laws, any defect reported prior to warranty expiration must be fully repaired by the manufacturer, even if the final repair occurs after the mileage threshold. The current mileage is a direct result of Hyundai’s internal diagnostic and loaner delays.Demanded Resolution:I demand that Hyundai cover 100% of the transmission replacement costs immediately. I am hoping this escalation to the NHTSA will help in bringing this matter to a positive end result, otherwise I have no choice but to pursue formal legal remedies.

This complaint concerns a serious, unresolved powertrain/propulsion safety defect in my 2023 Hyundai Santa Fe. While traveling approximately 70 mph, the vehicle suddenly lost propulsion and would not accelerate normally while surrounded by highway traffic.MOST IMPORTANTLY, THERE WAS NO WARNING OR ADVANCE INDICATION. No warning lights, messages, or symptoms appeared before the loss of propulsion. I had no opportunity to anticipate the failure or prepare to safely exit traffic. This placed me and other motorists at immediate risk of a serious or potentially fatal collision.A Hyundai dealership inspected the vehicle and documented DTC P284001, Shift Fork D Position Fault. Despite this documented fault, the underlying safety issue remains unresolved. Hyundai has not identified a permanent correction or established that the vehicle is safe to operate.There has not been another incident because I will not risk another sudden loss of propulsion by driving the vehicle. The absence of another failure does NOT mean the problem is resolved. The vehicle remains available for inspection.I have repeatedly sought assistance from Hyundai and the dealership without a meaningful resolution. Newer information regarding a possible computer reset/relearn procedure has also been presented, but the dealership refuses to perform it.I reviewed NHTSA complaints for 2023 Santa Fe vehicles and found multiple reports describing similar safety symptoms, including sudden loss of propulsion, inability to accelerate, abnormal transmission shifting, and loss of speed. This raises serious concern that this may not be an isolated failure.A vehicle that can unexpectedly lose propulsion at highway speed WITHOUT ANY WARNING creates an extreme crash risk. I respectfully request that NHTSA review the similar complaints, investigate whether a broader transmission/powertrain safety defect exists, and determine whether corrective action is necessary before this results in serious injury or death.

I was driving, and the SUV all of a sudden lost power. I was trying to press harder on the gas pedal to keep up with the traffic, but the SUV was stalling. The SUV would not move, and as I kept trying to press on the gas pedal, a roaring noise like something was trying to turn but the engine kept trying to move the car. It felt like something in the car was trying to move but something kept slipping. I had to turn the car off in the middle of the street and restart it before it would move. Cars were blowing their horns. This is a safety issue and a dangerous Problem. The SUV just did the same thing a few days ago. I am calling the dealer to see what is wrong. I brought this car new 2023. It is under 12,000 miles
