I had an oil change, rear differential service, air filters changed, and an engine coolant drain/refill performed on Thursday of this week.

I drove for about an hour on the interstate today and a few seconds before reaching my destination, the CEL began to blink and I received a p0305 error code. I also received the following:

- Check VSA System
- Check SH-AWD System
- Check Emission System
- Check Hill Start Assist System

Should I have it towed, is it okay to drive it home (and then to the dealership), etc?

Thanks in advance.

p0305 is a misfire code in cylinder 5 (front-middle cylinder).
If the car seems to be running fine you are probably okay to drive; but that's your call.
This code will sometimes cause the other "check" lights to illuminate.

A multitude of issues could cause this code.
Because of the timing of the code so close to the service preformed, I would troubleshoot the systems that were worked on.
Check to make sure air filter box cover is installed correctly.
A incorrectly installed air filter box cover did cause a misfire code on my Dad's Odyssey once (p0303 rear-driver). Why I don't know, but it did.
Check coolant level. Sometimes is takes several hot-cool run cycles to get all the trapped air out of the system.
