2023 Hyundai Sonata

Reported this previously, but more information was gathered, thanks to collision mechanic who guessed immediately when he heard 2023 hybrid Sonata - he said "they're notorious for it." Was at a stand still in a parking space/lot I know well. Cautious driver, watch my speed, very aware of other drivers, quick reaction time. Incident mid day, no pedestrians, distractions, no moving traffic. Vehicle doors shut, seat belt on. Not on incline. Pulled into parking spot I use weekly, spot has parking curb. Was at a full stop. Realized I had not pulled into the spot quite far enough, and attempted to inch vehicle forward. (Do not recall any warning lights, but this car usually alerts at literally anything - even shadows.) Very lightly applied gas to inch forward, slowly. Felt slight "scrape" of undercarriage on the parking curb. Put car in reverse, lightly applied gas to inch back. Car did not rev, no screeching tires, it was at a standstill previously. Was in Eco mode. All seemed normal, until vehicle suddenly launched UP the parking curb, full force, and into a building pillar directly ahead. The car never moves with that much force, I'm not a pedal-to-the metal driver. Eco mode on. No airbag deployment, injuries, etc. Sheriff took report for the building, simple incident. I couldn't make sense of it. I know how overly cautious I am while parking, what I do, and don't do. Took responsibility, but was still analyzing a week later, and explained what I remembered to the mechanic. He guessed right away. Said Sonatas were notorious for it. He said they're known for randomly applying the ebrake unexpectedly - and also randomly releasing the ebrake - and aggressively (and silently) switching from electric to gas when met with resistance, aka the parking curb. Insurance totalled the car. 2.5 years old, 17k miles. This was my 3rd Hyundai in 20 years, others were great. Discovered 40,000 Elantra hybrids, same year as my Sonata, were recalled due to "unintended acceleration."

Car was parked, full stop, doors shut, seatbelt on. Foot on brake. Car then seemed to lurch forward by itself forward hitting parking cement block. Put in reverse to back away and car stayed still...then I tapped the gas again to back up and insted vehicle plowed forward.instead.of reverse ...went over the parking block and hit concrete beam in front, when the car should have backed up in reverse. I'm a person who drives speeed limits, and ulta careful when i drive, and parked at this place/spot for years. This has never happened not sure why it did. No injuries or other people involved thank god, but scared the heck out of me. Wracking my brain, my recalls and software and service appts are up ro date.Nothing out of ordinary that day. I'm confused and shaken, why the first lurch forward and why did going in reverse move it forward? ugh. It drove home fine. Commute to work daily for years, no issues. All I can guess is gear didn't click to reverse and was somehow in drive? Ive been going over the possibilities in my head for human error but they dont make sense - again I've been driving for 40 years. If it happens to other models, would love to know! Car will go to repair tomorrow as "my fault" via insurance, hoping they can see more if any error codes, to at least say if Reverse didn't engage or something else happened. May have been human error but it's so out of the ordinary for me. Thanks!

Forward Collision Warning appeared, vehicle lost power and would not accelerate. Vehicle kept loosing power. Multiple codes appeared. I am an ASE certified mechanic, so I went to my own business to get my scanner and there was a list of codes. Vehicle is currently at dealership and they are tracking down issues. Currently blaming an ECM but unsure. This is the second vehicle I have had this exact issue with. I have video that it won't allow me to upload of all the codes. I have a video of a previous issue, with a different vehicle. It's a 2023 Hyundai Santa Fe
