#2846 of 2924 2010 Mustang Faulty Trunk Latch Mechanism
Nov 19, 2009 (10:58 am)
I got my 2010 Mustang GT some time in September of 09, and pretty much from day one, there seemed to be an intermittent issue with the trunk latch mechanism.
About one out of five times, while opening the trunk using key button, I get a weird somewhat loud vibration sound (coming from the trunk latch/solenoid mechanism) instead of a typical single thunk that usually happens when it works correctly. After that vibration happens, the trunk may or may not be still locked. I think there's a 50% chance a second press of the truck release button is required to unlock the trunk. It always works after the second request. Furthermore, about one out of 20 times, after I get the above issue, the trunk wont close since the latch toggle hook mechanism is flipped. This is solved by manually resetting the hook and pressing the trunk release button again and then closing..or something along that procedure.
I decided that I'd bring it up on my first maintenance service which I did yesterday at 5300 miles. The service rep said that the mechanic/technicion found the trunk to be misaligned with the latch. The trunk was "recentered", and he said the problem was solved. Looking at the trunk, I could see that it was now shifted about an 1/8th to a 1/4 of an inch to the right. Off center. I was a bit annoyed, but if it solved the latch problem, I was fine with it. Next day, (this morning), I got the same latch/solenoid vibration and trunk didn't open on first request.
I want my rear trunk lid recentered and I want that latch mechanism replaced. It's obviously faulty. Actually, I was told two weeks earlier by someone from Ford that this latch/solenoid mechanism is known to be faulty and has been replaced in later production cars (after the month mine was manufactured). He even scheduled to have the part sent to a local dealer and have it ready for me to pick up. It was my fault for forgetting the name of that dealership. I should have mentioned yesterday to my service rep about this but I didn't because I didn't want to seem pushy. I hoped they would know about the problem or figure it out themselves and order the part on their own. Just goes to show you, the repair you get at a dealership does not guarantee a propper fix.
I'm annoyed but not upset because service was prompt and they are very polite which I value so much! I don't fault them too much since their solution was kind-of a reasonable fix, given that they probably didn't know about the issue. I was told by someone from Ford that the faulty latch only appears in 2010 Mustangs produced in the first several months. It's been replaced with a redesigned one after that.
Now, I expect and hope for prompt correction of the issue. I'm reasonably confident I'll be satisfied with their response and I will post what happens as usual.
By the way, I love the car overall. Especially the engine note and rear wheel spinning torque delivery. Reminds me that 1968 movie "Bullitt".

When using your remote you need to press the trunk release button twice. It won't open if you press the button once. It must be some sort of safety mechanism. It's on page 99 of your Mustang Owner's Guide. I looked it up when my trunk failed to open when only pressed once. Hope this helps. I also have a 2010 GT and love it!

considering the recent news of the 2011 powertrains. The V6 is finally going to get some competitive HP and a noteworthy engine for 2011 and the 5.0 is finally coming back to the GT. Nobody cares?

cares?? I'm pissed and excited at the same time! I just got my 2010 GT and have invested about $2200 in handling mods. Regardless; if the 5.0 comes out, I don't think I'd be able to resist trading my car in for long. By the way, the next generation 3 series will be comming out shortly after the 5.0. For me, these will be really fun comparing (and test driving ). And Yes, I do think the current Mustang is comparable to a 3 series in many important respects.
I don't know how Ford will pull off bringing back a 5.0 in such politicaly charged times regarding the environment. 5L sounds like a whole lot even if only 0.4L more than the current engine. It will be a challenge to their engineering and marketing teams to avoid a negative backlash. I hope they succeed since the 5.0 is a legend.
I'll be blasting my 4.6L GT in the mean time.

Easy - the 5.0L will get better fuel mileage than the old 4.6L.

Hmmm, 8.5% more fuel but still better fuel mileage. That sounds like a tough cookie to pull unless they bump up to 6-gears. I hope not. I think 5 is plenny. Heck, I'm driving around in 4th all day, and I've got a 3.73 rear gear ratio.

It will be 6 speeds for both manual and auto. It's nothing more than giving engineering a common goal (fuel economy) and getting out of their way. The V6 will get 30 mpg highway and a significant bump in city (at least 2 mpg I think) while going from 210 hp to 305 and from ~240 to 263 in torque (approximately). More efficient engines can give you both - power and FE.

I was on the cusp of adding a 2010 GT to my garage since I miss my '05 GT so much. I'm glad I waited. I was actually wanting to hold out for an IRS, but a 5L V8 w/ 400HP (or more) will suffice. Wonder how long before aftermarket powertrain/drivetrain parts will be available.

good timming! I had to buy when I bought, knowing full well of the likely hood of a 2011 5.0! Too bad Ford doesn't lease, at least not Mustangs. I may have to take a hit and trade up provided the economy doesn't degrade further next year.
One cool thing about the prospects of 6 gears is that it enables Ford to safely offer a significantly higher rear gear ratio. Imagine a factory 4.75+ option? That sounds enticing.
