I was driving again and the engine died again. This time it will not start again. It sounds like the starter engages for a split second and then no sound. To me it sounds like the starter cannot spin the flywheel which to me indicates the internals of the engine no longer turn either.

There was no warning really. I did feel a pop in the pedal when it did it. No knocking or noises otherwise. The check engine light never blinked like Hyundai claims it will with the new ECM cluster update.

Has anyone else had this happen? If so, was the engine replacement process difficult? I work tomorrow, my car is 105 miles away at a dealer with no appointment. I just didn’t want to tow it all the way back here at 350 dollars.

Did you try a jump start?

Dead battery caused by dead alternator or seized engine. With Hyundai's engine rep, hope you're under warranty

It has power. The starter engages and I can hear it start to spin but then it can’t spin. I’m sure the dealer will try to jump it just in case that’s the issue, but I’m thinking the engine seized. :/

High probability the engine has seized - has to be a big pain for you happening where it occurred. If so might want to consider going to the NHTSA (if you are in the USA) are report that the wonderous product improvement update failed to do what it Hyundai claims it is supposed to do and that your engine seized without warning. I would.

Have You tried starting it in Neutral.? checked Battery terminalls for corrosion?
or taken them off for a cleaning.
battery terminals look good. My brother who is a mechanic looked at them.
Did not try to start in neutral. Tried from park. It’s 105 miles away at a dealership now. They can try that if they wish to lol

One Quick way of finding out if engine is in fact seized is to put a wrench on the end of the Crankshaft Pulley and see if You can turn the engine by hand, if You cant its seized. hopefully its not Your engine but a bad starter or wire connector of sort. Good Luck on the find keep us posted on the outcome.

Yeah I didn't think of that at the time. I was kind of pissed sitting in the parking lot lol. I can't imagine a bad starter would stall the car out though. Possibly electrical though. The way the car sounded when I tried to start it again makes me think it is seized though. Just a clang noise rather than the normal engine spinning and trying to run noise.

Same symptoms with my 2014 sonata. I checked my vin numbers and my engine was not listed on the recall when i checked on 2016. July 2019. Engine shut off while coasting to a red light. No start. Tried jumpstarting. No go.

Had car towed to Hyundai dealership. Diagnosis. Seized engine.

I have the 10/100000 warranty. Car had 45600 miles on the ODO. They honored the warranty. Gave me a free rental car.

Engine replacement took about 3 weeks. From paperwork to job completion. They replaced with a refurbished engine. Brand new internals. New intake manifold. They reuse the high pressure fuel pump.

Sometimes an accessory item pulley can seize and prevent the engine from cranking properly
Hey, just a thought.
Maybe check to see if the alternator or power steering is seized
This might help prevent spending a lot of money on something not needed?

The starter will burn a belt to turn an engine over...a huge amount of torque there. I haven't seen what you're suggesting in my limited experience.

I have seen a seized alternator prevent an engine from starting
And making it very difficult to turn over
And as far as seeing a belt burn, I have seen that too.
But, I am suggesting to check it.
What does it cost compared to buying and installing another engine??
Just take off the accessory belt and crank engine
If it cranks or not will tell you right away.
