I have a used 2015 Hyundai Sonata that I purchased from a Hyundai dealership in December 2021 (due to the chip shortage, I had to purchase used). A few months later In June 2022 I was driving on the freeway and my car felt like it was losing acceleration. I was already planning to exit the next exit to go to my destination and as I was exiting and came to stop at the red light before I could then turn right .. my car started to violently shake. Ultimately, after going to my own car place the following day and them determining that the fuel injectors and the computer were not talking, I had it towed to Hyundai where after another 4 days they also determined it was that problem and they replaced the computer under warranty. Well today I was again on the toll road / freeway and I was in the fast lane, I suddenly felt a strong jolt and my malfunction light came on and it was blinking on the dash, I knew not to drive it based on the light and as I steered to the right shoulder to slow / stop and call AAA I could feel my car just lightly shaking again. My car is now at the same Hyundai dealership where I purchased it and I’m waiting for diagnostics on the problem. Before this all happened, the first time in 2022 I was having sporadic issues with pressing the start button and there was a bit of a delayed start at times, even after the computer was replaced I’ve still had hiccups with the start button at times but it’s been very sporadic and it has never been a starter issue (had my car place already check that). So I’m now waiting to hear if the computer indeed failed for a second time. They cannot assess my car until Monday or Tuesday at the dealership (today was a Friday, my car was towed there at about 11am today). If the computer did fail again, it lasted about 14,000 miles before it just died again. Quite frustrated at the moment. I already contacted Hyundai corporate and opened a second case today regarding all of this.

I own a 2015 Hyundai Sonata and have an issue with dash pad, the passenger side air bag has split at the airbag seam and has traveled to the drivers side. If the passenger airbag deploys, I could see some severe injury to the passenger side occupant when the airbag deploys after the cover detaches from the rest of the dash pad. The lifespan of any safety system component is 15yrs according to NHTSA

My driver side seat belt when taken off does not retract back to normal position. Also my color urban Sunset is starting to fade on the back spoiler and truck Area. Thank you Any help would be appreciated

In September 2022, we noticed a noise coming from under the car hood. Sounded like a thump as we accelerated. We took it to the Hyundai’s service department and was told that they couldn’t hear anything or find a problem. They changed my oil. We continued to hear a noise but thought it wasn’t a concern. In February, a fairly new tire went flat and we returned to the Hyundai service department. I received a call later and was told that they could hear a noise and they checked, and my oil was extremely low. They topped it off and told me to return in a thousand miles to see if it was still burning oil. If it was burning significant oil at that point, they would seal it and begin the Hyundai oil consumption test. At about 600 miles, I could smell a strong plastic burning odor and we checked the dip stick and the oil was barely detectable. We called Hyundai and was told there was nothing they could do and we have to go the full thousand miles to determine if we qualify for the test. We are concerned are engine is going to stall, burn up or catch fire in our garage. They told us, we couldn’t get are car in to be looked at until the end of March. After doing some research, I am aware that there is a current class action lawsuit against Hyundai for this issue.

Ports internal to valve cover were blocked. Oil blowing out of valve cover jacket, filling spark plug wells and causing misfiring. Concerned about fire hazard for all leaks.

2015 HYUNDAI SONATA. CONSUMER STATED THAT THIER VEHICLE WAS BUILT WITHOUT AN IGNITION IMMOBILIZER.

A Aknocking noise from the engine that increases in frequency as the engine rpm increases. A Reduced power and/or hesitation and vibration. A Illumination of the "check engine" light in the instrument cluster.

Sensors lights would indicate an issue and would disappear sometimes without any reason (mainly Check Engine and Tire Pressure Sensors). Indicators would trigger the opposite direction (indicate right and the left indicator would turn on). Burning more fuel than expected. Primary fuel pump stopped working resulting in car stopping in the middle of the road.
