While driving under normal highway conditions, the sunroof detached from the vehicle while still in the closed position. This caused extreme danger to other drivers and property and could have caused a fatality if it would have hit a motorcyclist or other unprotected person. There was a recall for this (Recall Campaign 152: 2015-2016 Sonata Panoramic Sunroof) and the vehicle was delivered to the dealer during the recall period for inspection and presumed fix. There was no warning that anything was wrong previous to the incident.

The contact depressed the accelerator pedal; however, the vehicle failed to respond as needed. The contact stated that the vehicle stalled, and there were several unknown warning lights illuminated. The contact stated that prior to the engine failure, engine oil needed to be added every week. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the engine had seized and needed to be replaced. The dealer informed the contact that the vehicle was not eligible for an engine replacement because an engine software update had not been performed. The vehicle was not repaired.

While traveling on local roads and highways the vehicle transmission randomly down-shifts one or two gears. This has occurred when traveling in any gear from gears 3 through 6. It probably doesn't happen in 2nd gear because that is a transitory gear and not a cruising gear. After quickly moving the shifter from automatic mode into manual mode and then back into automatic mode the transmission returns to the proper gear. However sometimes it has down shifted again in as little as 30 to 60 seconds after resetting the shifter. This has been happening for years. The dealership has been unable to fix it. Because it is random, the issue is not readily reproducible by the repair shop. Sometimes it has happened several times within a 15 minute period. Sometimes it has occured multiple consecutive days. Other times a week or two has passed with no incident.

My pearl white 2015 Hyundai Sonata Sport’s paint is chipping off while im driving causing paint chips to fly which has almost caused me to wreck. This is happening on the trunk roof and passenger front door.

The low pressure fuel line connector to the high pressure fuel pump failed and sprayed fuel over the hot engine. This could have easily cause a vehicle fire and death. This is a KNOW ISSUE and is covered by a safety recall on 2013-2014 Hyundai Sonatas (Hyundai Technical Service Bulletin 20-01-030H). The same issue occurred on this 2015 Sonata that was built in June 2015. A temporary repair had to be made until Hyundai could inspect it. Vehicle was taken to Holler Hyundai in Winter Park, FL and inspected. Results were forwarded to Hyundai Motors America and the repair was declined because the 2015 models were not included in the recall. It is our belief that the same connector was also used on some 2015 Sonata models prior to the issue being discovered.

Hyundai is denying a lifetime warranty claim on my 2015 Hyundai Sonata. Recalls have been completed on my vehicle and even with knock sensor recall completed my engine light is not on and they will not grant me a new engine. If though the Hyundai Dealer agrees that the engine has the bearing issue that would grant me a new engine.
