Battery Management System failed Safety-Could not drive on interstate. Very unsafe. Dealer inspected problem afterwards. Warning lights appeared at time of problem. No warnings before. No signs of problem before it happened. SYNOPSIS: After driving through a torrential thunderstorm on the interstate (06-13-25) and as we were getting ready to slow down for our exit on the interstate, we hit the brakes and our SUV gave us a warning. The warning said, "Battery Management System Discharge". The SUV is a hybrid. At this point the SUV locked into E V mode. Our SUV would only go 10 mph which was very dangerous. It should be able to go up to 35 mph in E V mode and then past that, switch into gas mode. As stated, we could only go about 10 mph. We made it to our exit and found a spot to pull off the ramp. We let the SUV sit for a few moments and turned it off. We let it sit for a minute and then turned the car back on. The SUV when we turned it back on gave us a check engine light and still would not go over 10 mph. Luckily we were stopping for dinner. We were able to proceed to our destination. After dinner around an hour or so, when turned the vehicle back on, the SUV still gave us a check engine light. but was able to drive normally and switch between E V and gas modes. We made it home safely at the end of the weekend on 06-15-25. On 6-16-25 we took the SUV to be looked at by the dealer we purchased it from. Our phone app showed code DTC P0AA600. We gave the code to the staff. The staff inspected the SUV. The report stated, "customer states stopped driving and there code P0AA600 Battery Warning Light NPF Could not duplicate problem. Tech scanned for codes Code P0AA600 was found as a history code. Tech checked live data and everything came back within spec. Followed the flow chart procedure for the code.

I leased a brand new 2025 Hyundai Tucson on March 15, 2025, with fewer than 10 miles on the odometer. Shortly after driving an additional 10 miles, the vehicle-??s screen malfunctioned, displaying burn-in and becoming non-functional. This issue significantly affects safety, as it renders the backup camera unusable during operation. The vehicle was first brought in for service on March 17, 2025, but the issue was not resolved. Subsequent service attempts were made on March 20, April 9, and most recently on April 11, 2025. As of today, the problem remains unresolved. The vehicle has been in the service center for approximately 15 days since the date of purchase. In addition to the defective screen, the vehicle failed to start on one occasion, leaving me stranded alone in a parking lot, stuck in accessory mode with the brake locked. The car has also exhibited alignment issues, consistently pulling to the left while driving, which has required two alignments since the purchase date.
