2021 Hyundai Palisade · Trailer wiring
Tow-hitch wiring harness short and fire risk
Moisture or debris in certain genuine Hyundai tow-hitch harness modules can cause a short and a fire while driving or parked.
What the reviewed source says
Start with the documented condition, not a parts guess.
Hyundai recall 235 covers certain 2020 to 2022 Palisade vehicles that may have a genuine Hyundai accessory tow hitch and wiring harness. The module can short after moisture or debris contamination and create a fire risk even with the ignition off. The current repair adds a protective extension and lower-rated fuse after inspection; a failed harness is replaced.

What the official procedure directs
Hyundai tells dealers to inspect the genuine accessory harness and take the prescribed electrical measurement. The result determines whether to install the extension repair or replace the harness assembly.
Recall 22V-633 is based on tow-harness fitment and vehicle production records, not mileage.

Complete Hyundai recall 235

Identify the tow connector from outside
Without opening the module or touching wiring, note whether a tow connector and genuine Hyundai hitch are fitted and photograph them for the dealer. Check the VIN under recall 235.
Do not handle wiring that is warm, melted or giving off an odor.

Read the method beside the problem
These guides explain the safety and evidence checks that apply to this problem file.
Check recalls by VIN
A VIN search checks the displayed NHTSA records for an unrepaired safety recall associated with one vehicle. A model search shows only the wider campaign population.
Read guide ↗When a car is unsafe
A warning light does not always mean the same thing, but weak brakes or smoke leave little room for experimentation. Damaged tires and certain recall instructions can do the same.

“It makes a weird noise” is useful human language. Diagnosis begins when that language is tied to the exact vehicle and its operating conditions.
