Recently purchased a 2014 CX-5 GT AWD and opted for the new fancy electronic rust protection thingy that attaches under the hood and repels positive / negative ions (however that works, I have no idea). Anyways, from the research I've since done over the internet suggests that this method of rust control is less than proven (or desired). So, I'm contemplating bringing my vehicle to Krown to have them spray it...which I will also do every year or two afterwards as it's not that expensive.

Some folks have told me that Mazda had some very serious issues with rust in recent years. Has this been resolved?? Is anyone having issues with rust on their mazdas using this new electronic gizmo?? Am I going overboard by opting to have it sprayed as well?? The sales guy told me that places that spray (Krown, etc) can't get to all the spots needed..and that they would drill holes into the metal thereby negating any warranty given out by the electronic gizmo company (is this true??).

Has Mazda addressed their rust issues with recent models (like the CX-5)??

Asking for your viewpoints and opinions here.

The electronic rust thing doesn't work, period!
It works on bridges, using current. If it worked on your car, your battery would be dead everyday (maybe this is the issue with the CX-5 battery problem!). Just another scam that sucks your battery dead.
They used to be mounted with screws, but the screws would rust, so they use velcro now!
Spraying is best, make sure they get in behind the wheel wheels really good. You must tell them when you bring your vehicle in, just before the actual spray application-----if you tell them 1 week in advance it will not happen. All the way around the wheel wells, from in front of the tire all the way around top and to back behind the tire.

They will have to access the wheel wells from inside the vehicle to spray behind it!

 

Yeah ive also been worried about the rusting on my mazda and was wondering if anyone knew the difference between Krown and other products?

 

It took 17 Minnesota winters to finally eat up my '91 B-2600i with no rust protection. Didn't get really bad until year 14 or so.

 

Krown is the best but I have to ask first because I have never had a car with all that protective undercarriage moulding. How do they even spray? Do they have to remove panels? Take a look under and you will see what I am talking about.
