While travelling at highway speed, attempted to accelerate to pass slow traffic. Rather than accelerating, the car hunted for a gear, and wouldn't shift properly. The car downshifted but engine would not go beyond 4000 RPM and speed remained the same. This has happened multiple times. By unexpectedly not accelerating, this created a risky situation by not allowing car to pass slower traffic…
2023 Hyundai Santa Fe powertrain problems
severe 38 complaints filed with NHTSA · avg repair $2,500 · see powertrain across all vehicles →
Owners have filed 38 powertrain complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Powertrain accounts for 19% of all owner complaints filed against this vehicle, across 10 categories tracked.
The failure pattern owners describe
Buyer takeaway: The 2023 Santa Fe powertrain has a documented pattern of unexpected stalls, transmission failures, and acceleration loss affecting multiple owners within the first year of ownership. Dealerships cannot reliably diagnose these issues, repeated visits often yield no repairs, and the problems recur—creating real highway safety risk.
The 2023 Santa Fe powertrain cluster centers on sudden loss of ability to move or accelerate. Multiple owners report complete engine stalls while driving at highway or city speeds, forcing emergency pullover. After shutdown and restart, the vehicle operates normally until the next incident—sometimes weeks later, sometimes months. No warning lights precede many of these events. Dealerships typically cannot reproduce the issue and tell owners no problem exists; in one case, a dealership claimed a repair at month five, but the stall recurred within months.
Transmission malfunctions are reported repeatedly: unexpected shift to Neutral while in Drive (engine running but no propulsion), inability to shift out of Park, and refusal to downshift when acceleration is needed. Some owners describe being stuck in eighth gear on the highway or first gear in city driving, forcing manual paddle-shifter operation on an automatic transmission. One transmission was replaced in 2023 but the same fault code returned in late 2025.
Acceleration hesitation is widespread—a 1–5 second delay between foot-on-pedal and actual movement, or the engine revving without the car speeding up. This happens sporadically, some owners report monthly occurrences. Dealers cannot duplicate the problem or find codes. The vehicle may limp at 20–40 mph until restart.
Secondary issues include park-shift failures (car rolling when placed in Park), emergency brake slamming on unexpectedly, brake squealing and warped rotors at low mileage, alarm triggering randomly, and heating/cooling system malfunctions. Most events occur within the first 15,000 miles on brand-new vehicles purchased in 2023. Dealerships consistently state no codes exist or refuse further diagnostic work.

Failure modes owners describe
Unexpected stalling / loss of propulsion while driving
Engine stalls completely while vehicle is in motion, causing sudden loss of power and ability to move. Vehicle requires restart to resume normal operation. No warning lights or fault codes present in many cases. Occurs on highways and city streets at various speeds (25-75 mph). After restart, vehicle operates normally until next incident.
When: Incidents reported from 3,000 to 68,000 miles; multiple cases from 1,700 to 12,506 miles on newer vehicles within first few months of ownership
Symptoms owners cite: Complete engine stall while driving; All electrical systems shut down (alarms, check lights, dashboard); Loss of forward propulsion on highway or city road; Vehicle requires shutdown and restart to recover; Dashboard warning lights flash intermittently during event; Vehicle reverts to normal operation after restart
Codes mentioned: P2118, P2101, P065312, P1C2D03, P284001, P0112, P0114
Repairs/costs cited: Dealerships unable to reproduce issue in majority of cases despite multiple service visits. One owner reports dealership claimed to have fixed part after fifth incident (November 2024) but problem recurred within months. Another owner waited three weeks with no resolution and was told issue could not be duplicated. Throttle body replacement attempted in at least one case without permanent resolution.
Recalls/TSBs owners mention: Hyundai case numbers opened for some owners; lemon law request denied in one case with suggestion to sell vehicle. Dealership throttle assembly replacement and front camera replacement attempted. Manufacturer has been notified in multiple cases but no recalls issued for 2023 model year despite owner references to recall 236 on earlier model years.
Transmission stuck in neutral or unable to shift out of park / loss of gear engagement
Transmission unexpectedly shifts into neutral while vehicle is in drive or fails to shift into desired gear. Transmission indicator on dash may remain in Drive while vehicle is actually in Neutral, causing loss of propulsion with engine still running. Vehicle may be unable to shift out of Park. Occurs without driver input. Self-corrects after vehicle is shut down, waited a few seconds, and restarted.
When: Reported from 6,273 miles to 55,817 miles; many incidents within first few thousand miles of ownership
Symptoms owners cite: Transmission shifts into Neutral involuntarily while in Drive; Transmission indicator shows Drive but vehicle won't move; Engine revs but no forward propulsion; Unable to shift out of Park despite driver input; Vehicle loses motive power without warning; Issue self-resolves after shutdown and restart; No warning messages or indicators before event in most cases
Codes mentioned: P1C2D03, P284001
Repairs/costs cited: Dealership unable to diagnose errors even with GDS (Hyundai diagnostic software) in multiple cases. One owner reports transmission was replaced in 2023 but same code reappeared in December 2025. Another received warning 'Transmission error. Check transmission fluid immediately!' but dealership could not replicate error after three weeks. No transmission fluid check confirmed by owner.
Recalls/TSBs owners mention: Manufacturer notified in multiple cases with case numbers opened. No recalls issued for 2023 model year. Owner notes this is similar to Safety Recall 236 for earlier model years (through 2022) and requests recall for 2023 models.
Delayed or sluggish acceleration / limp mode / unable to exceed 20-40 mph
Vehicle fails to accelerate normally when pedal is depressed. Engine RPM increases but power is not transferred to wheels or transmission does not downshift appropriately. Vehicle enters limp mode, capping speed at 20-40 mph. Can occur from complete stop or while already moving. Self-resolves after vehicle is shut down and restarted. Occurs sporadically, sometimes once per month; delay lag can last 1-5 seconds.
When: Reported from 3,000 to 15,000 miles; most incidents early in vehicle ownership
Symptoms owners cite: Engine RPM increases but vehicle does not accelerate proportionally; Vehicle enters limp mode, limiting speed to 20-40 mph; Transmission hunts for gear or refuses to downshift; Hesitation or delay between pressing accelerator and vehicle acceleration (1-5 second lag); Vehicle feels like transmission is slipping; Engine revs to 4000 rpm without speed increase; Problem worse in certain driving modes but occurs in all modes; Intermittent; happens sporadically, sometimes once monthly
Codes mentioned: P2118, P2101, P065312
Repairs/costs cited: Dealerships unable to reproduce issue in multiple visits. Throttle assembly and camera replacement attempted without permanent resolution. No repairs completed in majority of cases. One dealer refused further service without $200 diagnostic charge. Software update performed in one case with no improvement.
Recalls/TSBs owners mention: Manufacturer case numbers opened in some instances. No recalls issued. Software update attempted in at least one case without resolution.
Unintended Park or Neutral engagement / vehicle rolls when parked
Vehicle shifts into Neutral or Park unexpectedly while parked or moving. Vehicle rolls forward when placed in Park despite no driver input. Safety feature (driver door opens = car shifts to Park) failed in one case, allowing vehicle to roll while operator was exiting. Vehicle may fail to engage Park when Park button is pressed while vehicle is in motion, with vehicle taking off instead.
When: Incidents reported from under 1,000 miles to 15,000 miles; early in ownership in multiple cases
Symptoms owners cite: Vehicle rolls forward immediately after being placed in Park; Unintended shift into Neutral or Park without driver action; Driver door open safety feature fails to engage Park; Vehicle accelerates instead of going into Park when Park button pressed; Vehicle in motion fails to respond to Park input; No warning lights or messages before events
Repairs/costs cited: Dealership inspected in one case and claimed no error codes found. No repairs completed. One owner's vehicle crashed through garage door and into garage with no repairs offered.
Transmission downshift issues / improper gear selection for vehicle speed
Transmission fails to downshift when acceleration is required or downshifts abruptly without driver input. Vehicle may remain stuck in higher gear (8th) or lower gear (1st or 3rd) unable to increase speed appropriately. Engine downshifts but RPM does not increase beyond 4000, preventing vehicle acceleration. Transmission gear selection does not match driving speed, causing safety hazard.
When: Reported from 11,000 miles onward; incidents at various mileages
Symptoms owners cite: Transmission stuck in high gear (8th) unable to gain speed; Transmission stuck in low gear (1st or 3rd) at highway speeds; Abrupt unexpected downshift without driver input; Engine downshifts but RPM capped at 4000; Vehicle unable to maintain posted speed (70 mph unable to exceed 35 mph); Manual transmission behavior required despite automatic transmission; Paddle shifter required to manually shift gears
Repairs/costs cited: At least one owner required to use paddle shifters to manually shift transmission at 11,000 miles. No transmission repairs completed in cases reviewed despite diagnoses indicating transmission failure. One owner at 68,000 miles reports transmission failure with reference to earlier recall 236 on oil pump failure.
Electronic throttle control malfunction (codes P2118 / P2101)
Electronic throttle actuator or throttle control motor malfunctions, causing loss of throttle response or reduced engine power in limp mode. Check engine light illuminates and remains on. Fault codes P2118 and P2101 displayed in Hyundai Bluelink app. Issue is confirmed but not yet repaired due to delayed service availability.
When: Warning light first appeared late January 2026; ongoing issue
Symptoms owners cite: Check engine light illuminated and remains on; Loss of throttle response or reduced engine power; Vehicle enters limp mode; Risk of stalling while driving; Fault codes P2118 and P2101 displayed in Bluelink app
Codes mentioned: P2118, P2101
Repairs/costs cited: Vehicle not yet inspected by dealership due to delayed service availability. Owner considers vehicle unsafe to drive due to active fault.
Shifter system malfunction / shifter will not respond
Dashboard displays 'Shifter System Malfunction - Service Immediately' warning. Vehicle fails to shift into Park or Reverse when driver attempts to do so. Vehicle may put itself into Neutral involuntarily. Shifter becomes unresponsive to driver input.
When: Reported at 18,192 miles and early in vehicle ownership (under 4,000 miles in one case)
Symptoms owners cite: Dashboard warning message 'Shifter System Malfunction - Service Immediately'; Unable to shift into Park when attempting to do so; Unable to shift into Reverse; Vehicle puts itself into Neutral; Shifter unresponsive to driver input
Repairs/costs cited: Vehicle towed to dealer but not diagnosed or repaired in reported cases.
Recalls/TSBs owners mention: Manufacturer not notified in one case. One owner reports EMS module replacement performed by dealership for this and related issues.
Transmission shuddering / transmission slip during acceleration
Vehicle shudders or feels like transmission is slipping during acceleration or take-off. Vehicle makes significant noise and may refuse to shift out of gear. Transmission slip feels like clutch slipping in manual transmission vehicle. Progressive shuddering reported during take-off, acceleration, slowing down, and braking, especially uphill.
When: Reported from 1,000 miles onward; some cases within months of ownership
Symptoms owners cite: Transmission shuddering during take-off; Transmission slip sensation during acceleration; Significant noise from transmission; Vehicle shaking immensely; Progressive shuddering during acceleration, deceleration, and braking; Feels like driving manual transmission when operating automatic
Repairs/costs cited: One owner reports at 11,000 miles transmission stuck in first gear with tachometer redlining at 6000 rpm, requiring paddle shifters for manual control.
Brake issues / failed emergency brake engagement and disengagement
Emergency brake engages unexpectedly when driver attempts to accelerate or fails to engage / disengage properly when parked on hills or flat surfaces. Emergency brake light on dash blinks intermittently, making it unclear if brake is actually engaged. Vehicle may slam emergency brake on when accelerating from stopped position. Brakes squeal and may fail to stop vehicle properly.
When: Reported within first months of ownership; escalating issues over 1.5 years of ownership in one case
Symptoms owners cite: Emergency brake engages unexpectedly when accelerating from stop; Emergency brake fails to engage properly when parked; Emergency brake fails to disengage when attempting to drive; Brake light blinks on dash intermittently; Unclear whether emergency brake is engaged or not; Brake squealing; Warped rotors at 3,000 miles causing brake failure and shaking
Repairs/costs cited: Dealership replaced EMS module, brakes, and rotors in one case. Brake pads sanded and cleaned in another case but squealing continued. Front rotors and pads replacement needed. One owner reports dealership won't drive car until rotors replaced due to safety concerns.

Automobile approached and stopped at stop sign. When accelerator pressed to continue, car remained in place, shuddering (as if transmission were slipping),and making significant noise. Car would not shift out of gear, nor move. Operator shut off car and then restarted car. Car started normally and was in park without shuddering. Expectations at busy intersection was that it was my turn to…
This same scenario has happened 3 times since I purchased this vehicle - first event at mileage of 6273, 2nd event @ 7586 miles, and 3rd event @ 12,506 miles. All events were the same - while driving, dash board light start to flash and the vehicle looses all ability to accelerate. For each event, we have been able to coast out of traffic, turn the car off & restart. Once the car is…
The vehicle cannot pick up speed, and it is displaying the DTC- P1C2D03. This is similar to the issues that led to "Safety Recall 236 to repair a condition involving the 8-Speed Dual-Clutch Transmission (DCT) system" in earlier model years (till 2022) for certain Hyundai and Kia vehicles. NHTSA should issue a recall for 2023 model years also as Hyundai has not addressed this issue to the fullest…
Shuddering Issue with Current Vehicle: - Problem: Progressive shuddering during take-off, accelerating, slowing down, and braking uphill.
First- it has been reported to dealer at least twice when car was in for other service. They said they could not reproduce. When speeding back up from a stop on near stop, especially in a right turn, the engine will not accelerate. After a second or two it finally takes off. During this time, I fear getting hit by another vehicle, either from behind or to the side. It is very scary and puts me…
