Error codes p0100 and p0104 mass air flow?

[Jayy6]

I got an error message saying "drive modes not available, see manual" then when I tried to accelerate it wouldnt accelerate at all I could barely do 5 mph,

Anyone have this issue before, or have any suggestions?

First thing to do is clean the MAF sensor with dedicated MAF cleaner.
If that doesn't help start looking for loose connections/damaged wiring. Or maybe a vacuum leak.

Is this the right cleaner https://www.autozone.com/miscellane...ijNt2BpPxmeGZ325&gclsrc=ds&new_store_set=true

Well, it's literally right in the name so, yeah...
If you're unfamiliar with MAFs I'd suggest watching a couple of videos on the subject. They can be sensitive to how they're handled/treated

I kind of doubt the cleaner will help if the problem just suddenly occurred and the car was fine prior to this failure. A dirty MAF will slowly get worse over time so if this symptom occurred rather quickly, I suggest you check the MAF itself and the connections. Check the voltages at the MAF connector to verify that the supply voltage and ground are both OK, then check the output signal. It's possible your MAF sensor just quit/failed in which case replacing it will solve this issue. However, noting that your car is a 2022, it may still be under warranty if you're within the 3yr/36,000 mile range or if you have an extended warranty on it.

You make a good point. But cleaning is easy and fairly inexpensive for the cleaner. Most people don't really have the experience to do a lot of testing on electronic components nor the equipment.
Aren't the MAF sensors part of the emissions system? If so it may well be covered under the emissions warranty which is, I think 85k miles. So definitely worth checking out.

Soooo, what's done to the car? Any changes to it in the last 2 weeks? New tune?
