2017 Hyundai Sonata Plug-In Hybrid Other or unknown Problems

“The shark fin antenna cover came off the vehicle. When I parked the car, after driving on the highway, I noticed that it was gone. This definitely can pose a driving hazard if it comes off the vehicle while driving on the highway. I noticed that what was left of the base mounts appeared to be cracked which resulted in the fin breaking free. This definitely appears to be a manufacturing defect. It's approximately a $500 cost at the dealer to repair. This shouldn't happen after two years of car ownership. It will get very costly to replace this at the dealer every two years. …”

If anyone gets in, they cannot get out, especially with the Hybrids which do not have fold down back seats. Federal mandate states the trunk must have an operational emergency release, but with the trunk latch issue, the emergency release does NOT work.”

“Occurrence: This has been a recurring issue for over a year (over a year, might be closer to two years now) for our PHEV Sonata. It has happened approximately 10 times. Problem: Total engine shutdown when driving the car. Shut down engine type error message pops up and cannot accelerate. Steering still works, but it can be hard to pull over due to lack of engine power. The car can be restarted after shutting down, but must first come to a complete stop and into Park.
