My 2023 Hyundai Santa Cruz, which I bought new, has gone into limp mode twice in 8 months, losing power while I was driving and letting me go no faster than 25 MPH. The first time, in April 2024, I was on [XXX] in Hartford CT. I called 911 because I was certain I would be hit by a car. There was no warning lights to indicate a problem. I was able to get off the highway and had it towed to Meriden Hyundai in Meriden CT. They said they could find nothing wrong. On [XXX], my vehicle went into limp mode again. I was able to drive it to the same dealer since I work nearby. Again, they say they can't find the cause. I have been without a vehicle since then. The car is a danger to drive, and Hyundai has not resolved the matter, though I've been in contact with corporate representatives. Limp mode has caused many crashed across the country. It is designed to protect a car from a mechanical problem - but the system itself puts drivers at great risk. My hope is the NTSB will investigate my case and this national problem before more people are injured or killed.

Driving through my neighborhood. Went to enter a Hwy and tried to accelerate. Could only go about 25 mph. with engine speed fluctuating. Checked to see if I had hit paddles by mistake. That is what it felt like. Pulled over put in park. checked for dash notifications none. Got up to about 45, speed fluctuations again. Pulled over turned off ignition. That fixed the problem. Safety concern if traffic was heavier, I would have been rear ended easily. Was no place to pull over right away.

The Highway Drive Assist (HDA) designed to auto change cruise speed according to posted speed limit signs - at 80mph limit will auto change to 83mph and 85mph limit will auto change to 95mph. Hyundai has said this is not available to inspect.

The most major problem that occurred on 2-3 different occasions is that the emergency braking system activated for no reason on one occasion, almost causing a Rear end collision with a person behind me. No one to my sides, and in front of me on all of the occasions. Headlights on the automatic, setting on a bright sunny day, will turn off and on no change in lighting which annoys other drivers because they think I-??m flashing them. After starting the car in Drive the first time I break and then go to accelerate there-??s a delay in the acceleration. as well as other times while driving. Today, the back up camera didn-??t shut off when shifting into drive like it normally does it didn-??t go off until I went into parking pushed the radio button. I-??m pretty sure it-??s a computer issue
