My 2015 Hyundai Sonata has demonstrated multiple instances of unintended acceleration and braking failure: April 20, 2024 - While idling in a drive-thru line, the vehicle suddenly lurched forward without any attempt to accelerate and crashed into the vehicle in front of me. I was unable to stop it. This resulted in the other car being totaled. I took it to a Hyundai dealership afterward, but they found no definitive cause. April 4, 2025 - My daughter was driving and attempted to stop at a red light. Despite applying the brakes, the car did not stop and continued through the intersection, striking the door of another vehicle. May 12, 2025 - Today, while using cruise control set to 55 mph, the car began accelerating beyond the set speed without input. It appears the cruise control system is malfunctioning and not disengaging as expected. …
The car has had multiple issues with the hybrid system. I've taken it to the dealership about 4-5 times. They "fix" the issue but a little while later I'm having more hybrid warming issues. This last time I took it to a different dealership, paid for a diagnostic test, and was told my hybrid system was bad but because it was repaired too many times instead of replacing it, it's no longer covered under warranty. The issue from the last diagnostic test showed the master brake cylinder was faulty, I replaced it but I'm still having the same issue. The mechanic I took it to did their own diagnostic test and it showed there is an issue with the hydraulic booster, high pressure accumulator short term charge. When I searched the issue, I've found that many people are having the same issue with the same car/year as mine. …

I would like to write about my experience with New Port Richey Hyundai. I have owned a Hyundai Sonata Hybrid Limited since 2015. I take immaculate care of my car and it only has 65,000 miles. All maintenance has been done regularly and on time. For the last six months I have had a warning light and alarm going off for a few seconds once in a while, which shuts off my cruise control. I took the car in, in the spring of 2023 to have the codes read and no problems were found. Finally, In July of 2023, while my wife was in traffic it started again and totally shut off the car. Unfortunately, the brakes did not work as well. She was going up a slight incline and was able to come to a stop. The brake pedal went completely to the floor. The warning was about a Hybrid System Failure. It was very upsetting to her that her brakes failed when the Hybrid system had a problem. …
