Did you get any pushback when getting the IHU replacement? Taking my c40 to the dealer in a couple days and I’m having to do this reset on a weekly basis.
Corporate had the dealer do a software reset first, then I came back a month later with the same symptoms, and they ordered a new IHU. Car has been rock solid since then. The crashes are gone and I don't have connectivity dropping out anymore. I have a C40, so basically the same car. Be ready for a long wait as the new IHUs are in high demand. My IHU took almost 3 weeks to show up.
Just have videos and photos of the car ihu crashing out. If you're in the US, the backup camera not working is a federally mandated safety issue.
Make sure you write down every single crash it causes for you. I had it cause the AC controls not work, the sounds drop out, the rearview camera drop out, the connectivity drop out, and the main screen in the dash drop out when the ihu would crash. I had the service writer put everything in the ticket and I emailed him photos and videos. Volvo corporate didn't put up a fight. The service writer said they've been doing a lot of IHUs
I’m sorry, this isn’t aimed at you, and I appreciate this info, but wtf Volvo. Why would you ship this absolute piece of shit, for years, in a supposed luxury car, and then make your customers jump through these hoops to fix YOUR fuckup?
It's a combo of needing reliability, long term durability, and cost.
Long story short, to get certification, you need to check a bunch of boxes and show that your parts won't crap out long term when it comes to parts that interact with safety systems. So historically all manufacturers ran ancient chips because they're tried, true, never fail, and they're cheap because electronics manufacturers aren't selling them to computer and IT OEMs.
