This has happened to my 2007 Lincoln mkz. What did they charge to fix it at the dealer?Hopefully I've had the warped dash problem resolved at the dealers...I wanted it glued and screwed, but they did not want to glue it. They flattened it back to its original state, installed (5) screws and the new defroster cover. The screws are color matched and everything looks great. How long will it last ? They seem to think it will be ok. I have my doubts, but well worth a try. (Anyone wanting to try this, be forewarned... they said there was a chance of breaking the windshield in the process.)
Yea, this is my car now. Started with one break in the vent and now it's pulled the entire damn thing offYou were lucky ! You should see the dash on my 2008 MKZ -- the covering has rose up enough so that the plastic defroster vent has broken in THREE pieces ! Ford/Lincoln should be real proud !
what size screws did thay useHopefully I've had the warped dash problem resolved at the dealers...I wanted it glued and screwed, but they did not want to glue it.

No,I don't have photos, they put a total of (6) screws along the edge of the plastic vent piece (the edge that faces you as you sit in the car). They were small dark screws that had washers that seem to catch the edge of the plastic vent. They said there's a danger of breaking the windshield in the process, so be careful if you try it. Be sure you do it and keep the car in a warm environment...they told me that the screws would hold things down and give things time to re-mold. So far so good, but the weather here has been cool lately. I also bought the gas pressure hose described above in case what has started to lift on the outside edges. GOOD LUCK !
*Update*
I am having success with Loctite 410. I moved my defroster grid/panel towards the front of the windshield without disconnecting the sensor. Make sure to use vinyl gloves and apply the loctite to your index finger. Reach in and back towards where you are sitting and I suggest doing one side at a time since this sets up very quickly. Just apply it side to side on the underside of the rubber side that has come up. Replace the defroster grid and grab a thick heavy book like a encyclopedia britanica. Remember those? Wedge it under the glass and make sure it pushes down on the dash. Let it sit over night or at least a few hours to make sure you applied enough. Repeat for the other side and sit in the other seat lol. Don't rush it but like I said it does setup fast. So far, my drivers side is flat like new. I did buy loctite super glue for the defroster grid when I am done as I am saving that for last. It appears mine has a couple broken tabs. I will post pics when it's done.
Do you recall the charge for this? Thanks.Hopefully I've had the warped dash problem resolved at the dealers...I wanted it glued and screwed, but they did not want to glue it.

Did that last?A Dealer who purchased 2008 MKZ with a warped dash. The dash had at least 12 to 14 inches come loose at def vent and looked like a seagull taking off. Purchased on the internet a small bottle of loctite 410 instant adhesive. This stuff is expensive about $34.00 for small bottle but worth its weight in gold. It is a black glue the bottle has a long applicator tip. I was able to turn bottle side ways insert tip under the raised dash Be very careful as it sets up immediately. Took a pop cycile stick to spread it out push dash forward layed some books on it and you would not believe the results All hell could not pull it apart now looks as good as factory Wish I had some before and after pictures Be careful not to get on you or other part of the dash Did leave books on overnight. Put the new grill on and was flabbergasted at the great results Try it you will like it
Curious if anyone has come up with what they feel is a good fix? I see the LOCTITE fix and think that is the way to go but was looking for additional feedback. I see everyone mentioning sun/heat as the contributing factor. Not sure that is 100% accurate. The 2007 I am having this problem with was bought new by my elderly mom and always garaged. Car only has 42k miles on it.Did that last?
