Tow Hitch Harness Module Water Intrusion – Engine Compartment Fire Risk
Vehicle catches fire while parked or while driving; smoke or burning smell from engine area; visible fire near rear trailer hitch area
Fire recall + seat belt recall on your Santa Fe PHEV? Two safety campaigns and hybrid failures. California owners may qualify for a buyback. Free review.
You bought the Hyundai Santa Fe Plug-In Hybrid to get a premium family SUV with the fuel efficiency of an electrified drivetrain. What many 2022 and 2023 owners got instead was a vehicle with not one but multiple open safety recalls — including one that told them to stop parking in their own garage. The most serious issue is a tow hitch wiring harness defect that allows water to seep into an electrical module on the trailer connector, causing a short circuit that can ignite the vehicle while it is parked with the ignition completely off. Hyundai confirmed at least one fire and five separate thermal-damage incidents in the United States before it issued Recall 244 (NHTSA campaign 23V181) in March 2023 — covering 2022-2023 Santa Fe PHEVs and tens of thousands of other Hyundai and Kia models in the same family. The interim guidance: park outside, away from any structure. At the same time, those same model years are covered by a second safety recall — Recall 238/011G (NHTSA 22V816) — for a defective front seat belt pretensioner that can explode during a crash and send metal fragments into the occupant compartment. The vehicle's own safety restraint system becomes a potential hazard. California's Song-Beverly Consumer Warranty Act exists precisely for situations like this: when a manufacturer cannot fix a dangerous defect after a reasonable number of attempts. If your Santa Fe PHEV has been to the dealer for any of these recalls — or if you experienced the hybrid system failures, brake shudder, or rearview camera failure that affect this generation — your repair history may already tell the story California law needs to hear.
The issues owners report most, ranked by severity — each one verified against a cited NHTSA source.
Vehicle catches fire while parked or while driving; smoke or burning smell from engine area; visible fire near rear trailer hitch area
In a crash, front seat belt pretensioners deploy abnormally; metal shards or fragments are ejected into the cabin, potentially striking occupants
Dashboard shows 'EV System Failure' or 'Hybrid System Failure' warning; vehicle loses drive power or acceleration; vehicle stuck in or drops out of EV mode unexpectedly; battery charge not holding; power loss on interstate
Fuel smell inside or around vehicle; visible fuel drip from undercarriage; fuel level drops unexpectedly; fire risk if near ignition source
Steering wheel shakes or vibrates when braking from highway speeds (typically above 55 mph); whole vehicle shudders during braking; pulsation felt through brake pedal on hard or downhill stops
Rearview camera does not display image when reversing; black screen or error message on infotainment when in reverse; rear visibility completely lost

Vehicle catches fire while parked or while driving; smoke or burning smell from engine area; visible fire near rear trailer hitch area
Safety-critical fire recall. Vehicles parked near structures posed arson-level risk. Multiple thermal incidents confirmed by Hyundai prior to recall. Park-outside advisory issued — evidence of acute hazard. Strong lemon-law basis if fire or damage occurred pre-remedy or remedy failed.
Install 15A fuse and new wire extension kit per Hyundai Recall 244; dealers remove faulty wiring harness module
In a crash, front seat belt pretensioners deploy abnormally; metal shards or fragments are ejected into the cabin, potentially striking occupants
Safety system failure that makes vehicle non-compliant with safety expectations. Defect is latent until a crash. If client was in a crash where pretensioners were involved and suffered injury or if remedy was unavailable for extended period, strong lemon-law claim.
Dealer installs anti-separation protection cap on driver- and passenger-side front seat belt pretensioners at no charge (Recall 238/011G)
Dashboard shows 'EV System Failure' or 'Hybrid System Failure' warning; vehicle loses drive power or acceleration; vehicle stuck in or drops out of EV mode unexpectedly; battery charge not holding; power loss on interstate
Repeated HV system warnings, loss of power events, and dealer inability to replicate or remedy are classic lemon-law fact patterns. PHEV powertrain is unique and costly to repair; if HV battery or inverter required replacement under warranty, that supports substantial impairment. 62 battery/propulsion complaints in NHTSA ODI for 2022-2023 PHEV generation.
HCU/ECU software update; HV battery module or inverter replacement as needed; inverter cooling system inspection
Fuel smell inside or around vehicle; visible fuel drip from undercarriage; fuel level drops unexpectedly; fire risk if near ignition source
PHEV-specific fuel system defect. Fire risk from fuel leak in a PHEV (where battery/electrical components are in proximity) is heightened. Very small affected population (~326 units) means high chance client's VIN is within scope. Relevant if fuel leak caused drivability issues or dealer multiple repair visits.
Dealer inspects and replaces fuel tank free of charge (Recall 240)
Steering wheel shakes or vibrates when braking from highway speeds (typically above 55 mph); whole vehicle shudders during braking; pulsation felt through brake pedal on hard or downhill stops
Brake judder that returns after dealer resurface or rotor replacement, or requires multiple repair visits, strongly supports lemon-law claim. Regenerative braking in PHEV interacts with friction brakes and may accelerate rotor wear. TSB existence is an admission the original rotors were deficient.
TSB 23-BR-004H: dealer inspects, resurfaces or replaces front rotors and pads with updated part numbers; brake burnishing procedure performed at no charge
Rearview camera does not display image when reversing; black screen or error message on infotainment when in reverse; rear visibility completely lost
FMVSS non-compliance recall. If owner experienced camera failure and dealer could not promptly remedy (parts unavailability, multiple visits), this supports lemon-law claim on a safety system. Relevant where rear camera failure caused near-miss or property damage.
Dealer replaces rearview camera unit free of charge (Recall 271). Owner notification letters mailed January 19, 2025.
open
Damaged printed circuit board in the rearview camera may prevent the camera image from displaying, causing non-compliance with FMVSS 111 Rear Visibility requirements.
open
Water accumulation on the tow hitch harness module printed circuit board (PCB) via the 4-pin connector may cause an electrical short, resulting in a fire while parked or driving.
open
Fuel tank may have been improperly molded at the seam between tank halves due to a supplier manufacturing error, resulting in a fuel leak.
open
Front seat belt pretensioners may deploy abnormally during a crash, causing metal fragments to be ejected into the occupant compartment.
Every item below comes from this vehicle's documented defects. The more you recognize, the more a free case review is worth your time.
California's Song-Beverly Consumer Warranty Act — the state lemon law — gives you specific, enforceable rights when a manufacturer fails to fix a defect within a reasonable number of attempts during the warranty period. For a safety-related defect — such as a fire risk while parked, a seat belt that can injure occupants in a crash, or a sudden loss of drive power — California presumes that two repair attempts may be enough to establish a violation. For non-safety substantial defects, the threshold is typically four attempts or 30 or more cumulative days out of service (they do not have to be consecutive). If your Santa Fe PHEV qualifies, you may be entitled to: a full repurchase of the purchase price (minus a mileage offset), a replacement vehicle of comparable value, or a negotiated cash settlement. Critically, if you prevail, Hyundai is responsible for paying your attorney fees — meaning most California lemon law cases cost the owner nothing out of pocket. The Santa Fe PHEV's simultaneous open recalls for fire risk and seat belt safety, combined with the hybrid system failure pattern and parts availability issues, can all support a claim. This is general information only and is not legal advice; every case depends on its specific facts, dates, and repair history.
“Could not duplicate” doesn't mean the defect isn't real. Here's exactly what to do to protect a potential California lemon-law claim.
Document the moment it happens. Photos, video, and screenshots of any warning lights — with the date and the mileage.
Get a repair order every visit — even “found nothing.” That paperwork is the foundation of a claim.
Check your VIN at nhtsa.gov/recalls. Note any recall that has no available remedy yet.
Track your out-of-service days. California law counts the cumulative days your vehicle spends in the shop.
Keep loaner & rental records. Alternate-transport paperwork during long repairs matters.
Save everything in one place. Symptoms, dates, repair orders, and every repeat visit — the intermittent ones especially.
Dealers frequently close repair orders with 'unable to duplicate' (UTD) or 'no trouble found' (NTF) — especially on intermittent hybrid warning lights and propulsion complaints that reset on their own. Here is what to do if that happens to you: 1. Document everything before the visit. Write down the exact warning message on the cluster, the date, time, mileage, whether you had recently charged, the weather, and how the vehicle was behaving. Take a photo of any active warning on the display. 2. Ask for the Diagnostic Trouble Code (DTC) printout, including stored and pending codes — not just current codes. Hybrid system faults often set DTCs that the car then clears automatically. The stored code tells the real story. 3. Ask whether Technical Service Bulletin 23-BR-004H has been checked if your complaint involves brake shudder. If the dealer resurfaced rotors without applying the updated part numbers from that TSB, the fix will likely not hold. 4. For open safety recalls (23V181 / 22V816 / 24V879), ask the dealer for a written statement of whether the recall remedy has been completed on your specific VIN. If parts are on backorder, get that in writing. Days spent waiting for backordered recall parts count toward the 30-day out-of-service total under California law. 5. Keep every repair order, including UTD ones. Under California's Song-Beverly Act, a dealer visit that ends with no repair found still counts as a repair attempt. 6. Verify your VIN's recall status at nhtsa.gov for the most current open-recall list.
A park-outside advisory on a brand-new plug-in hybrid family SUV is not a minor inconvenience — it is an acknowledgment that the vehicle represents a fire hazard in the place most owners store their cars. Layered on top of that is a seat belt recall that turns a safety system into a shrapnel risk. When a vehicle carries two simultaneous safety recalls from day one and the dealer has open repair orders with no remedy available, the case for California lemon law relief is worth examining carefully. Gather your repair orders, note the days your vehicle was unavailable, and review your situation with a California lemon law attorney.

Has your Santa Fe PHEV been back to the dealer for the tow hitch fire recall, the seat belt recall, hybrid system warnings, or brake shudder? If your vehicle was out of service while waiting for parts, or if any of these issues have returned after a repair, your service history may already support a California lemon law claim. The consultation is free — find out where you stand.
If you own a 2022 or 2023 Santa Fe Plug-In Hybrid, your vehicle is covered by NHTSA Safety Recall 23V181 (Hyundai Recall 244), issued March 2023. The recall addresses water that can enter the tow hitch wiring harness module through the 4-pin trailer connector, causing an electrical short and potential fire — even while the vehicle is parked with the ignition off. Hyundai confirmed at least one vehicle fire and five thermal-damage incidents in the United States before the recall was filed. The interim owner advisory was to park outside and away from structures. The remedy is installation of a 15A fuse and a new wire extension kit at the dealer. You can confirm your vehicle's recall status by entering your VIN at nhtsa.gov.
NHTSA Safety Recall 22V816 (Hyundai Recall 238/011G), issued October 2022, covers 2022 and 2023 Santa Fe Plug-In Hybrids. The defect is in the front driver- and passenger-side seat belt pretensioner buckle assemblies: in a crash, the pretensioner can deploy abnormally and eject metal fragments into the occupant compartment, with the potential to injure the driver or front passenger. The remedy is dealer installation of an anti-separation protection cap on the front seat belt pretensioner buckles at no charge to the owner. Because this defect is latent — it only becomes dangerous during a crash — many owners may not know their vehicle is affected. Check your VIN at nhtsa.gov and schedule the repair if it shows as open.
An 'EV System Failure' or 'Hybrid System Failure' warning on the dashboard indicates that the vehicle's high-voltage battery or hybrid control system has detected a fault. Owners of 2022-2023 Santa Fe PHEVs have reported a range of related symptoms: sudden loss of power or acceleration, the vehicle dropping out of EV mode without warning, charging sessions that do not complete, and the battery charge not holding. NHTSA ODI records show 62 battery and propulsion complaints for this generation, covering hybrid drivetrain failures, electric propulsion losses, and high-voltage battery defects. There is no standalone recall for this issue as of this date, but a pattern of repeated warnings and dealer inability to reproduce or durably fix the fault is a classic lemon-law fact pattern. Document each occurrence — date, mileage, warning text — and save every repair order, including visits that end with 'no trouble found.'
Yes. Hyundai issued Technical Service Bulletin 23-BR-004H in November 2023 specifically to address brake judder — the shaking or shuddering sensation when braking from highway speeds — on 2022-2023 Santa Fe models, including the PHEV. The TSB instructs dealers to inspect front brake rotors for lateral run-out and thickness variation, and to resurface or replace them with updated part numbers at no charge. The issuance of updated part numbers is significant: it means Hyundai conceded the original rotors were underspecified. If a dealer resurfaced your rotors and the judder returned, ask whether the repair was performed under TSB 23-BR-004H with the updated parts. If the problem keeps coming back after multiple repair visits, that pattern may support a lemon-law claim for a recurring brake defect.
It may. California's Song-Beverly Consumer Warranty Act presumes a vehicle is a lemon if, during the warranty period, the manufacturer has made two or more repair attempts for a safety-related defect, or four or more attempts for any other substantial defect, or the vehicle has been out of service for 30 or more cumulative days. For the Santa Fe PHEV, the tow hitch fire recall and the seat belt pretensioner recall are both safety-critical — each requires only two repair attempts to meet the safety-defect threshold. If your vehicle also experienced hybrid system failures or repeated brake issues, those visits add to the count. Days spent waiting for backordered recall parts count toward the 30-day presumption even if the dealer had not yet started the repair. The analysis is fact-specific. Gathering all your repair orders and scheduling a free consultation with a California lemon law attorney is the best first step. If you prevail, Hyundai pays your attorney fees.
First, check your vehicle's recall status at nhtsa.gov by entering your VIN — the Santa Fe PHEV may have up to four open recall campaigns (tow hitch fire, seat belt pretensioner, fuel tank, and rearview camera depending on your model year). Contact your Hyundai dealer to schedule repair appointments for any open campaigns. If the dealer tells you parts are on backorder, request that information in writing and record the date. Under California law, days your vehicle spent waiting for parts or repairs count toward the out-of-service total that can support a lemon-law claim. Keep every piece of paperwork — the recall notice, the dealer repair orders, and any written communications about parts availability. If your vehicle has been in for any of these recalls more than once, or if your hybrid system warnings have not been resolved, those facts are worth discussing with a California lemon law attorney at no cost to you.
