If they share the same telematics, it should not matter what head unit they have if they run the same software. It’s like Dell runs the same Windows software as HP. Since they share the same telematics, Hyundai/Genesis can make a very small module, like the independent tech companies did, and simply plug it into that OBDII port as all makes and models have to have the same standardized OBDII ports. The OBDII port is the same on all vehicles made after 1995 or 1996, I can’t remember. It’s only the software that is different within the vehicle. Since the basic telematics software is the same on both the Hyundai/Kia/Genesis cars, it would be a simple inexpensive solution to this problem. If you read the link I posted earlier, a few auto manufacturers are offering a plug and play module to plug into the OBDII port and hook up to the LTE/SVLTE systems. I found a few other websites the go further into detail about the solutions each vehicle manufacturer plans to remedy the shutdown.
I started my aviation career as an A&P mechanic. I then enrolled in flight school since you have to have be certified to at least control an aircraft on the ground so why not finish the flying part. I do know a little bit about mobile telemetry, navigation, electronics, software, sensors, instruments, gauges and the like. It is of my opinion the fix to this would be an inexpensive LTE modem module to either plug in to the front end OBDII port or a simple module to be added to the back end of the OBDII more neatly integrated. 100% of all vehicle’s telematics flow through the OBDII port and can modify any parameter of the built in telematics software of any vehicle. I’m not posting to argue can it be done or not. It clearly can be done. I am arguing why Hyundai/Genesis chose not to address this serious issue like other manufacturers did. Especially vehicles that still have an active factory warranty. The federal law requires vehicle manufacturers to fix recall issues at their expense. Cutting off safety alerts is a recall issue. I realize they need to make a profit to operate. I am not against simple capitalism. What I am against is paying $$$ for options that were rendered useless and Hyundai saying, oh well too bad live with it when there is a simple fix. Even if they charge the customer out of warranty but fix for customers under warranty for free. It’s an inexpensive fix and I would happily pay for my upgrade since I am out of warranty. The independent tech companies selling an OBDII module are charging between $250 and $500 for LTE connectivity. Since I am out of warrant, I am exploring those options. But for those that own a vehicle that is under 5 years old, they should get the upgrade for free. Just my .3 cents.
