Do I need to update the firmware?

[maxley88]

Hi.

I bought a 2022 Mg4 SE Long Range last month, and I've checked the firmware today, and it ends with R13.

I've read on here that there are a few later versions, however I've also heard horror stories about the LKA and Collision Assist being dangerous.

At the moment, I've done about 800 miles, and not had any problems with either. I'm worried if I get the system updated with my next service, it will potentially lead to these issues.

If I refuse the update, will it void the warranty or anything?

Thanks!

Welcome to the forum.
There were a couple of updates so you may be on one of the better ones.
If it ain't broke...

Don’t forget that the R number only indicates what firmware your infotainment is on, it doesn’t indicate much about all the other modules on the car. Although one could argue if your infotainment hasn’t been updated in ages it’s unlikely the other modules are up to date.

The LKA was tamed by SC077 which won’t change your R number. If you want to make sure your car has received this update I would suggest contacting your MG dealer to see what they have on record.

Finally, updates are not a regular part of servicing and tend to incur a fee, so if you’re happy with your software it is unlikely your dealership would update without telling you, unless it’s an safety issue or they’re trying to fix something you’ve indicated (like lost Bluetooth connections).
