2019 Hyundai Sonata Complaints

  • Electrical System, engine, fuel/propulsion System 04/14/2026

    On April 14, 2026, my 2019 Hyundai Sonata was parked at a retail store parking lot. Returning from the store, I attempted to start the car, and it did not start. I attempted to start it again, and I saw smoke coming out from under the hood. I immediately exited the vehicle and opened the hood. I saw open flames coming out of the engine area, about 4” high. I called 911 and waited about 10 minutes for the fire department to arrive. During this time, the flames engulfed the entire engine compartment and extended vertically above the hood height. The hood eventually melted and fell back onto the engine area. The fire department came and put out the fire. The car is totaled. There were no injuries, thank God!

    My 2019 Hyundai Sonata has been experiencing excessive oil consumption since I purchased it. The vehicle requires oil to be added approximately every two weeks, which indicates a serious internal engine issue. Recently, the check engine light turned on, and I took the vehicle to a dealership for inspection. I was told that the engine is “operating normally,” despite the ongoing oil consumption problem. I was also informed that the engine would only be replaced under warranty if it fails completely, such as through connecting rod bearing damage. This means I am expected to continue driving a vehicle that may suddenly fail without warning. I drive daily with my children, and I am concerned about the risk of sudden engine failure, loss of power, or engine seizure while driving, which could lead to a serious accident. I believe this is a known issue with these engines, and it represents a significant safety hazard that should be addressed before a catastrophic failure occurs.

    I was driving on the interstate when my engine started shutting down on me and I’m glad I had moved to the right lane because someone would’ve hit me from the back because I never had this problem and now the mechanic telling me it jumped timing.

    My oil pan cracked. I’ve never had any issues with oil pans until this one. Hyundai will not replace this under warranty.

    I respectfully submit the following additional information.In connection with this matter, the dealer in question asserted in writing that I "should have refused to participate" in the manufacturer-authorized "Z05 Service Campaign"—a measure designed to prevent potential damage—and characterized the program as nothing more than "free paint work." Service campaigns administered by manufacturers are conducted within the framework of federal safety regulations pursuant to Title 49, Chapter 301 of the U.S. Code; they are neither optional nor merely cosmetic in nature. Rather, they constitute systematic procedures intended to preserve vehicle integrity and support public safety. Statements suggesting that consumers should decline participation in such campaigns—or that they may bear financial responsibility for damage incurred during their execution—raise concerns regarding how these federally supervised programs are communicated and implemented and may discourage participation and undermin...
