Hi, folks. Finally a Mazda owner after recommending them to others for years.
just bought a 2022 CX-5 turbo, Signature edition. And I noticed twice that after it’s shut off there’s a weird fan-like (or something) coming from the engine compartment. It seems to go away when the headlights shut off. Any ideas?

also, I ran the codes and got these notices:
c2011-87 4x “tire pressure wheel module: missing message

0077-00 low tire pressure: no sub type information

HUD code: u3003-16 Battery voltage: circuit voltage below threshold

park brake module code: c2006-07. Left actuator: mechanical failure

are any of all of these serious enothat I should head for the dealership?

thanks in advance! I look forward to hanging out with you guys!
cheers,
Jim

remote keyless entry code:b13d3-16. PATS transmitter circuit below threshold

 

Could be the headlights themselves. From the 2022 model and onwards they had lot of issues with the headlight fans and moving headlight parts breaking. It's covered under the 3 year/36k mile warranty.

 

Thanks! I didn’t know there were fans on the headlights. Never heard of such a thing!
ill Check into it.
cheers!

 

Sometimes these wiring noises are various component motors shutting down. Servicing many cars I do notice some have (to me) unusual shutdown noises that are obviously meant to happen.

 

If you are concern, then I recommend taking it to a service shop and have a qualified Auto Tech listen and tell you what the noise is. All of us guessing may end up with something that should be of concern to be dismissed.

Ditto. Definitely better to get it checked out than guessing.

 

Thanks for your replies! I’ll have it checked out.

 

Should be under warranty so yes get them to tell you what it is. Don't listen to a sales person get a tech to listen and please post back the outcome.

 

Often misunderstood or people not understanding an auto manufacture warranty . I recommend read and get clarity of the exact warranty coverage.Or contact Mazda corp direct. Mazda as well most platforms are specific for the systems like an example brakes or chassis parts not universally the same set miles or years over as a comparison example transmissions, tires or batteries.

This is also a question to ask the service department service manager or service writer at the dealer ship before your Mazda is signed in otherwise as most service contract you could be responsible for a service charge charged if the findings are not found to be covered under the warranty.

As an independent warranty authorized service Tech and shop I always make sure before I even perform a pre service inspection or work that it is a covered warranty so I get paid and I don’t have to charge the customer

 

Thanks!
