Issue with starting at the morning but not the battery. 
Solved
Hyundai Sonata 2017 68000 miles
Hello, I have a starting issue. I have a Sonata 2017, 2.4 GDI, automatic gearbox and automatic button start stop. At the morning, and more specially when it's colder, the car doesn't want to start immédiately. Battery has been changed, and oil also because it was time. The problem is still there. I'm thinking about the starter but not sure.
The central interface shows no issues, all instruments lights are blinking correctly. When I'm pushing on start (with my foot on brake pedal for sure) the car is trying to start (making the process but without any noise) and holding this process for 10 se… Read complete
CommentNo Power to OBD 2 Port
Hyundai Sonata 2015 SE 98300 miles
After lots and lots of diagnostic tests via a multimeter, visual inspection, changing any blown fuse (20A fuse underneath the dash for the PWR/CIG relay), which is known to also power the OBD port itself, there was still no power.
I finally opened up the panel to take the OBD-2 Port out for inspection and saw the wire for pin 16 was torn out. I have no idea if this is fixable without getting an entirely new port/harness to be installed ($$$)!!
So, any idea on the cheapest/easiest/most sensible route to take to get this fixed and power back to the OBD-2 Port so I can use my scan tools? (3 dif… Read complete

Going to take out the port and attached harness, attempt to take out the designated pins and install in the new OBD2 port (4-wired) replacement. I have the necessary tools for removal of the pins and wires, still self diagnosing without the most knowledge on this specific issue. We shall see, wish me luck lol!!

It’s a JDI system. You are most likely noticing it at lower speeds in those gears just refresh your transmission oil and motor oil.

When I drive the car, it suddenly stops working, then I return the gearbox to N and start the engine, and it starts working again.

Over Heating and ignition
Hyundai Sonata 2013 sedan 120000 miles
So, the car overheats. I changed the thermostat because I realised the old one was stuck and did not work properly. The overheating stopped happening, but it started again after some days. The coolant temperature sensor, when pulled off as an emergency measure during overheating, sometimes does not activate the fan immediately. I suspect an issue with the wiring or the fuse, but I'm not certain. The engine is an LPI engine, 2.0

Hyundai Sonata 2010 2.0L 160000 miles
OBD2 reader report: Replace Torque Converter Clutch Solenoid Circuit Performance Or Stuck Off. I replaced the automatic transmission fluid, but the solenoid(s) may need replacement. What is the easiest way to do this? Do I really have to remove the entire engine to access the transmission?
