Selected complaints filed with NHTSA by 2006 Ford Mustang owners, lightly cleaned up (personal details are redacted by NHTSA).
I came to a stop, looked to my left. Saw no car , and proceeded to leave to make a left. Car struck me on the left fender. Heard a long sound with white smoke all in the car that came from air bag, my face was struck so hard by the air bag that it made a large bump on forehead and eyes black in blue swollen with a headache that I've had for some days now. I've had to miss work all week, it also made me neck n side hurt.
1. Trunk too high; back windows slope blind driver from street light reflection. 2. Hood and windshield designed deny driver from seeing the curves coming on side angles. (causing vehicle ending up on curve) 3. ABS auto activate when vehicle going over pothole, causing slipping and driver cannot control the braking distance. 4. Ac/heat fan auto activate without consent even when sitting on off. I have a v6, 2006 Mustang. The safety issue that I have is the fact that the design of the vehicle that jeopardizing the children under 3 feet tall.: their trunk are too high and the slanted mirror block visibility. At night time backing out is very hard and there are many blind spots. I have backed up into another car already due to the poor visibility and light reflection: back window design with an angle that blind drivers when night light hits. The owner and I settled in cash. …
Tl* the contact owns a 2006 Ford Mustang. While the vehicle was stationary, water leaked into the vehicle from the passenger side and traveled to the back seat area. The contact stated that all of the windows were rolled up when the failure occurred. The contact stated that the water May have entered into the cabin from the seam where the hood met the front windshield. Willard's service center (4311 main street, grasonville, maryland 21638, [phone]) was made aware of the failure and replaced the heater coil on the front passenger side underneath the dashboard, but the failure recurred. The manufacturer was not made aware of the failure. The failure mileage was approximately 60,000.
My son-in-law bought a used Mustang convertible for his son. I had the car inspected and fluids changed as soon as I could and during the time on the rack, it was noticed that the frame stiffeners on both side showed severe rust to the point one was rusted completely through. The stiffener has an opening in the front that accumulates water, salt and road slop over time, but no method to let this member flush itself or be cleaned on the inside. The shop installed two new stiffeners with the same problem, but they closed the front opening entrance to the stiffener with a sealant and gave the bare metal exterior two coats of corrosion resistant paint.
The "well" underneath the windshield became clogged with debris, causing water to back up through the A/C vents into the car, damaging the electrical equipment. There are no instructions in the manual related to servicing this part of the car. Additionally, the door handles can become "stuck" in the open position without the driver noticing because the door still closes; however, the doors May come back open when the vehicle is operated.
There is bubbling in the paint in the tip of the hood which I have been told is corrosion on the exterior and interior. Ford will not take care of it saying it is out of warranty. This is a manufacturer's problem as there are many complaints and class action lawsuit pending.
Driving 40mph kn the right lane of a 4 lane highway with a cement median separating the east and westbound lanes. I hit some black ice, spun 90 degrees across the left lane and hit the median almost head on. Airbag did not deploy.
Rug on front passenger side is very wet. Just forward of the seat, just inside of the door sill. Appears to be water, not coolant. Unknown source. Door rubber seals are fine, as are window channels, door drain slots are clear.
Stress fractures on forward face of rear spoiler attach struts (both mounts). Vehicle less then a month old with less then 600 miles. 2006 Ford Mustang gt. No apparent reason for cracks in composite spoiler. Cracks are not surface cracks (very deep) and do affect spoiler mount integrity. Fractures are located on the forward face / bottom of the struts, centered and starting at forward mount bolts and extending upward. Suspect spoiler attach nuts on studs, over torqued during factory installation. Multiple fissures extend over two inches on each strut and May result in spoiler detaching from trunk deck lid. Ford declined warranty repair, stating cracks were caused from "an outside source." from personal experience in composites, as an aircraft mechanic, suspect stress fractures from mounting error, exposed via airflow over spoiler, creating a down force and over loading strut mounts. …
2006 Ford Mustang is leaking excessive amounts of water onto front floor board area, beneath dash. Water is saturating electrical components, including fuse boxes and other electrical components, causing what I believe to be a serious hazard. An internet search of "Mustang leak" will produce multiple hits of many other owners experiencing the identical problem. Ford has released TSB 08-26-7 detailing the problem for model years 2005 - 2009. Considering so many year models involved, this is obviously a design flaw in the manufacturing of the vehicle. Ford has yet to recall this issue and according to the local dealer, Ford does not consider this problem related to safety, which explains the lack of recall. Excessive amounts of water pouring onto the interior electrical components should be investigated as a possible safety concern. There were no events leading up to this incident. …
