Is this a known problem?
The manufacturer has sent NHTSA 2 service bulletins or notices for the 2020 Hyundai Palisade that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.
If you are servicing an 8-speed vehicle with a âCheck Engineâ light on and one or more of the DTC listed, follow the service procedure and replace the related solenoid and harness.

Should you keep driving it?
This page can't tell you that. 0 of 31 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
