#654 of 978 Lincoln Aviator Parking Brake Gear Shift Release
Apr 30, 2008 (3:38 pm)
I have a 2003 Aviator Kitty Hawk Edition. No major problems to 80K. However, now I am experiencing a brake gear shift release problem. When in park, sometimes, I cannot move the console gear shift our of park to drive. I do hear the clicking when the brake pedal is depressed but it stays locked. It does seems to try to engage but doesn't catch all the time. The dealer said that it might be the gear release solenoid. So it's a $400.00 gamble. I would hate to be in an emergency situation with this problem. Any advice?

Hey Warren, this is Warren also.I have the same problem with my 04 with 70k.My gear shift moves up and down vertically.Does yours? I think this may be to blame.When I step on the brake, push the button and shift in perfect unison,no problem. Even the slightest hesitation,problem.I have the extended warranty but I opted for the $100 deductible. At that rate every covered repair adds up. I'll be taking it in soon. I don't want to be stranded in an emergency situation.It's odd that they didn't mention the neautral safety switch as a possible cause.I've had two chevys and two fords that have exhibited the same symptoms.I'll keep you posted.

Thanks for your response. My gear shift is in the middle console. I am procrastinating for now since it works 90% of the time. So I am still investigating.

Warren, I have an 03 Aviator, had the same problem with the gear shift. Unfortunately for me, it finally came loose one day at a gas pump. After about 20 mins of freaking out, I took the thing apart and was able to drive it home. If you pull down the leather piece surrounding the base of the gear shift knob, you will expose a small screw about half way down the base, place the knob so that it sits in place and tighten that screw. It should fix the problem of the knob moving up and down vertically. It did for me. Apparently this screw holds the thing down. Itís a spring loaded mess in there once the knob comes loose. Hope this helps.

Note to Warren: Be sure that you hold the knob down when pulling down the leather piece on the shifter as the screw may already be loose. This will save you a good deal of trouble because putting the whole thing back together is not that complicated but can be a bit tricky.
#659 of 978 Check Park Assist message
Jun 12, 2008 (6:41 am)
My 2004 Aviator intermittently displays a 'Check Park Assist' message when I backup. When the message appears on the dashboard the beeping doesn't work. However, on other occasions it works just fine (beeping and no message)! The owners manual mentions that this display message exists, but it doesn't say why it happens, or what to do when it happens. Can anyone provide details?

Just wanted to know if you had any followups on your post. I have a 2005 Aviator and the same thing is happening to me. The "Check park assist" warning comes up quite often. Is it the sensor going bad?

I had an 04 Aviator. I had the check park assist message come on intermittently many, many times. The dealer replaced the sensors several times and it fixed the problem until the next time a sensor went bad. I probably had 10 sensors in total replaced.
That was just the tip of the iceberg concerning the problems I had with that vehicle. I had the trim piece on the tailgate crack also. There is a TSB on that problem.
I had three new transmissions put in before the car had 1700 miles on it.
There was constantly something wrong with it. I am glad my dealer was so understanding and took good care of me.
Thankfully, I traded that car off and I haven't looked back.

The problem is not with the ignition coil; that is just a way for Ford to avoid action by the EPA on the emissions warranty.
A Ford Technical Service Bulletin has been issued that identifies the problem with premature valve wear, primarily on the left head of the engine. It appears that this occurs as early as 50,000 miles, but as late as 115,000 miles (as with my engine). The cost of rebuilding the head is equal to replacing the engine with a new one (about $7,000). This affects all Aviator engines as well as some installed in the Mustang and Navigator.
If you get the warning light, move fast because the next thing that will happen is that you will fail your next smog check (if required in your state). In California, this means that you can't sell the car until it is repaired.
Don't expect any help from Ford unless you are under warranty. They seem to have forgotten that you should be able to get at least 250,000 miles before you have to replace an engine.
It was because of this problem and the defect in the Aviator climate control system that I gave up on owning Fords for forty years and finally bought a foreign car. I now have an Acura MDX; although it took a couple of months to get over not having that "Ford" feeling, I am very happy that I made the change.

The problem you are having is that cylinders 7 and 8 are fouled and you need an engine rebuild. The head/valve cover on this V8 comes in two pieces. It fouls around 50k miles and needs to be rebuilt. Ford should recall the engine and fix it gratis. There is a TSB on it. Ask a Lincoln Mercury Dealer and they know the TSB. All engines of this type, Ford puts in Ford Mustang, Navigator and Maruader fail. Mine failed at 52k miles and they covered part of it but not all of it. My 6th and last Ford btw. The dealer will quote $5500 if beyond warranty. They will pick up part of the tab if you push. Time for a class action??
