Hybrid system on other Sonata years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024.
What this problem usually is
These reports come from hybrid, plug-in and electric vehicle owners whose car put up a system warning and lost power, sometimes dropping into a reduced-power mode on the road. Others describe a car that won't charge, a high-voltage battery or inverter replacement, or a problem that turned out to be the ordinary 12-volt battery all along.
What got replaced
Owners who name the part that was replaced mention the charger or port (4 reports) and the drive unit (4 reports).
Recalls and investigations
3 recalls on the electrical system cover the 2014 model year. A recall on the same system isn't always the same failure, so read the defect text.
The high pressure fuel pipe that connects to the fuel pump outlet may have been damaged, misaligned, or improperly torqued during the engine replacement procedure, allowing fuel to leak from the pipe.
Machining errors during the engine manufacturing process may cause premature bearing wear within the engine.
In the affected vehicles, the transmission shift cable may detach from from the shift lever pin.

Should you keep driving it?
This page can't tell you that. 0 of 26 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
