I don't have experience with this specific issue but I'd ask them if the part is an updated part and if it's a known issue? They're addressing something that's wrong, so provided they button it up right you should be good. How long have you had it and how many miles are on it?

 

Bought it in June this year, has about 8000 miles on it now.

 

>replacing the rear motor.

Could be a completely different problem, but it is the closest post I've seen, might be worth a read: Rear Drive Gear problem caused Ioniq 5 to be a lemon, anyone else?

 

I am sure a new one is as good as the original. Inverters are typically reliable but nothing is 100%. It does sit on the motor and it’s basically your “carburetor” equivalent to a gas engine . It allows electricity to get to the motor from the battery at variable levels when you press the accelerator pedal. It also diverts power from the moTor back to the battery when regenerating. Keep us posted on the progress of The new one. Hopefully the part is available and you will be on the road soon.

 

Could be an inverter issue as well as a vehicle or motor sensor issue. Did they replace the inverter, and have you seen any issue since? Also do you have the inverter part number?

 

They told me they replaced the drive motor. The receipt they gave me had zero details and no part number unfortunately.

It was replaced 6 months ago now, it's been about 10,000 miles and 7 months since I first had the issue and it hasn't happened since.

 

The inverter is basically bolted to the top of the motor. I could see reasons why Hyundai would replace just the inverter or do a combined inverter & motor swap. As mentioned the inverter is the power supply & controller for the motor and it handles a lot of current, which is why it's on one of the cooling loops.
