Buyer takeaway: A 2022 Palisade's electrical system has spawned persistent issues: a recalled tow harness with an incomplete interim fix still waiting for parts, frequent child safety lock failures that leave doors openable while driving, and random speedometer blackouts. The more serious problem is that Hyundai's recall repairs are not being completed, one vehicle caught fire, and owners report the manufacturer downplaying the scope of problems.
The 2022 Palisade electrical complaints break into two camps: system-level failures and a major recall stuck in limbo.
The towing harness fire recall (235/22v-633, issued August 2022) is owners' biggest headache. Hyundai's interim fix simply removes a 40A fuse, which disables trailer brake and signal lights—a setup that's not a repair, it's a work-around. Owners say Hyundai promised a permanent fix (new 15A fuse plus wire harness kit) by May 2023, but dealerships don't stock the parts. One Palisade caught fire in the driveway; the fire department traced it to the driver-side rear wiring, and the dealer had already marked the recall closed. Complaints document owners calling Hyundai and dealerships with no resolution, while repair completion statistics get reported to NHTSA as done.
Child safety locks fail frequently and unpredictably, cycling through rapid clicking with a dashboard "child safety lock failure" warning. The feature disables itself at random, then re-engages. One owner had the lock switch replaced under warranty; it failed again within a week. Multiple owners note the doors become openable while the vehicle is in drive.
Speedometer needle drops to zero while driving, sometimes with the compass pointing wrong and the infotainment system warning of wrong-way travel. One instance self-corrected after a battery disconnect; another dealer couldn't replicate it.
Secondary electrical gremlins include unintended engine restart (one overnight, filling the cabin with carbon monoxide), sudden engine shut-off at 50 mph on a highway exit with brake impairment, and a parking sensor error that disables forward collision warning in reverse.
