I do this when i can too, most of the time in the summer. Has to be good for the hoses and belts also.

I don't have any bubbles.

 

I was amazed when I would pull the stang in the garage and could see the heat coming from the hood extracors on my '13.

When I had the Boss I would pop the hood when I was done driving it for the day.

I don't think the underhood head caused the paint bubbling issues that are being seen. My sisters '12 had the issue from the day she bought it.

 

Hello everyone,

Please make an appointment with your dealer to have the bubbling looked at and diagnosed. Also, PM me with your VIN, dealer, mileage, full name, and best daytime phone number so I can escalate this concern for you.

He may have mentioned this to see if you are in the 3 year/36,000 mile warranty coverage.

Have a good one, folks!
Andrea

 

my 09 has 4 miles on the clock. car has never been licensed, just sits there except bi-weekly startup/move around to keep tires semi round...was flatbedded from michigan to my garage where it sits covered- its had small blisters since first time I checked a couple yrs ago- after finding my 06 hood was shot.

my wifes 07 has blistering also, but keeping a eye on it...she dont drive hers in the rain, but has almost 20k on it now.

my 06's hood had what I'd thought were just seam sealer bumps, but over a 6 month period went to huge patches, and up over the top. put a Fang shaker hood on a couple yrs ago, the old hood is up in the rafters, so far it doesnt seem to have spread...lends me to believe it only spreads with water exposure. the 06 sits out all summer long, zero weathering top or bottom except for the old hood and the wiper arm paint fading...has never been in salt.

still think ford not prepping the sharp edges before crimp, and this is what causes paint film failure at the underside and eventual corrosion creep. the 'iron contamination' story dont sit well with me- if that edge had been deburred before crimp/ecoat that paint would be intact. thats my opinion, and im sticking to it

before the 09 gets washed again, will be finding a suitable caulking that wont attack paint, and running a bead around the underside edges(save front corner drain holes- which are too tiny IMO) to minimize moisure exposure to the underside sharp lip. I wouldnt have it looked at under warranty, as touching it woulda just insured its return worse, heard a several guys getting theirs fixed to see it return in a yr or two(gets it out of warranty though).
might do the same caulking to the wifes 07, but shes the 'dont touch my car' type...my 06 I tore apart the first week I had it dec 05, she came out saw the fenders/hood/doors off and freaked...lots of seam sealer/rollon bedliner/paint/hours sealing all but lowermost drains, not a single hint of rust except the driveshaft/axle housing(still bare). her 07 has telltale hints of corrosion at seams in front control arms, other places like that...i also wipe down my undercarriage at oilchange time with oily rags.

love these cars, but ford needs to get a handle on crimping aluminum panels and sealing hems. look at a door hems on a hyndai- hate foreign crap, but they are crimped and sealed beautifully, with nice drains. ford (gm worse) looks like the panel edge was hacked out with a axe and crimped by hitting with a rock in comparison...OK, thats a stretch, but look at a hyundai/others out there- some oems obviously put a lot of effort into sealing 'unseen' areas that ford does not.

This has been a hot topic since I bought my 2007 GT/CS. At the time I traded a 2005 Chrysler Crossfire. This car line had serious rusting problems along the bottom of the doors, although I never experienced them. The answer, was a DIY fix. Clean the area, and apply POR-15. This stops the rust. No heavy sanding and it comes in several colors, although using touch up will make it look factory. Of course this will only work on the underside of the hood, unless you plan a repaint of the hood. I have been lucky and never had a problem, with the Mustangs and my current one has over 25000 miles. But, I do dry and wax the area on a regular basis. As others have mentioned, I also pop the hood when temps are up.

Forgive me, Andrea, but what good will any of that do? You and I just discussed a few days ago that Ford is no longer fixing paint-bubbling under warranty unless the corrosion has eaten through the metal?

Did I misinterpret something?

 

I also have bubbling on the front edge of my 11' Kona, so this is sad news that Ford will not honor their warranty on something like this. Not trying to disrespect Andrea or Ford for that matter, I plan on buying many more in my lifetime, it would just sadden me to not have a paint defect covered in the bumper to bumper warranty unless it has escalated to the point that it is eating through the metal. But it sounds like that's why she included "let them diagnose it" to see if it has gotten into the metal and will in fact be covered by warranty.

 

Can a moderator please clean this thread up so that the Ford representatives will actually read it and help us out?

 

Done

 

Except this type of corrosion won't eat through the metal. They're aluminum hoods.

 

Whoops...your move Andrea :-)

 

Hi Rjaniz,

I confirmed that your dealer was correct in their explanation of the warranty coverage for your specific year and mileage. Please see the explanation below to clarify your confusion.

If you still have questions or want me to escalate your concerns, feel free to send me a DM.

Hello Loyal 'Stang Fans,

The issue that you all are discussing may or may not be covered under warranty. It depends on several variables. That's why I recommend talking to your Service Manager and having it diagnosed as soon as possible.

Ford Motor Company will repair, replace or adjust covered parts found to be defective in factory-supplied materials or workmanship. Depending on the repair needed, there may be different time and mileage coverage periods. Warranty expiration is based on time or mileage, whichever occurs first.

• Bumper-to-Bumper Warranty - 3 years or 36,000 miles
• Powertrain Warranty - (For vehicles 2007 and newer - 5 years or 60,000 miles
  
• Powerstroke Diesel Engine Coverage - 5 years or 100,000 miles
• Corrosion Perforation Warranty - 5 Years
• Safety Restraint Warranty - 5 years or 60,000 miles for vehicles 2007 and newer. 5 years or 50,000 miles for vehicles 2006 and older.
• Emissions Warranty - Coverage varies depending upon vehicle.
  

For specific warranty information such as the time, distance, and limitations of warranty coverage for your vehicle, please refer to your warranty guide. I can find the latest printing for each of you. Just send over a request with your 'Stangs' model and year in the subject.

Even if you are out of warranty coverage range, I can still document your concerns. I'll need your VIN, mileage, full name, dealer, and best contact number to escalate.

Let me know if I can assist further,
Andrea

 

So if I'm reading that right...
If you're under 3yr/36K - Hood (specifically) paint bubbling is covered.
If you're over 3yr/36K - Only sheet metal (such as fenders, trunk lids, doors, etc) is covered once the rust eats through the metal. (because, again, aluminum oxidation doesn't eat through the metal, but it will still bubble the paint)

If that's the case, I kinda have mixed feelings about this. I mean, I know Ford can't be expected to hold my hand through the life of the car and I wouldn't expect them too...but this still is a factory defect that reared it's head only a couple years into ownership. And considering I seem to be in the minority of owners to have this issue (given our very scientific poll above :P), I'd like to think it wouldn't hurt Ford's bottom line too much to include ALL paint bubbling in that 5 year corrosion protection. I'm sure it'd certainly foster some extra brand loyalty.

Meh, my commentary aside, thanks for the clarification!!
