Hyundai service campaign LA1, LA1A
Hyundai filed this with NHTSA as a service campaign dated Nov 13, 2025, received Nov 18, 2025, about the seats — 1 document under this number: LA1/LA1A DCS. It names 3 model years (2024–2026). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationCertain Santa Fe (MX5A) and Santa Fe Hybrid (MX5A HEV) vehicles may experience battery drain and inoperative heated seat capacitive touch buttons due to incorrect ECU logic for the Seat Heater Unit – Front (SHU_FRT). Technical Service Bulletins (TSBs) 25-01-025H-1 and 25-01-028H-1 provides instructions to perform a software update for the Seat Heater Unit – Front to correct the logic. Over-the-Air (OTA): This update can also be conducted via OTA. The customer can complete on his/her own if he/she has an active subscription to Hyundai Bluelink. A visit to the dealership is not required. Deployment of the OTA to Bluelink customers is planned to start the week of 11/11/25.
