NHTSA Complaint #11678563 — 2023 HYUNDAI PALISADE

We purchased this car new around June 2023 from a local Hyundai dealer. The car has been regularly maintained (at the dealer) and only has 20,000 miles approximately. In April of this year, my wife was drive on a very busy highway and suddenly all of the warning lights came on the dashboard and the car shuddered to a very rapid stop. She was lucky to pull off the road or it would have been serious. We got it into the dealer and they called a few days later to say it was fixed. Unfortunately, it was not. It happened again on June 20th this year. We had it towed back to the dealer. It has been there since (today is August 5th). They claim they cannot locate the issue and have been working with Hyundai Motor to troubleshoot. I filed a complaint with Hyundai (and really no assistance offered). Last week, they told us it was repaired and to come get it. My wife barely made it out of the lot before it did the same and came to a sudden stop. Not sure if this is happening to other Hyundai vehicles but this is certainly a dangerous situation... and the fact that they cannot determine the cause or how to fix, we are very concerned.
