ENGINE

I have experienced two engine failures in my 2005 Ford Mustang due to timing chain issues, specifically the failure of the timing chain cassette, guides, and tensioners in the 4.0L SOHC V6 engine. The first failure happened suddenly with no warning, resulting in severe bottom-end damage, including rod knock. The timing chain cassette ends tend to snap off, sending debris through the engine and damaging lifters, camshafts, and other critical components. The second failure was preceded by an audible “death rattle,” a known symptom of timing chain guide and tensioner failure. Despite this, my vehicle never displayed a check engine light or oil pressure warning before either failure. Unlike later Mustangs with an oil pressure gauge, mine only has a warning light, which never activated.This issue poses a major safety risk, especially at highway speeds. My first engine failure occurred with no prior symptoms, which could have led to an accident had I been merging or overtaking. A failing timing chain can cause misfires, loss of power, or sudden engine shutdown, endangering the driver and others on the road. Independent mechanics have confirmed this issue, and Ford service centers recognize it as a common problem with the 4.0L SOHC V6 engine. Ford has quoted $3,000–$4,000 for timing chain service, making repairs nearly as expensive as engine replacement. These engines rely on multiple chains and hydraulic tensioners that wear out over time, causing slack in the timing chain, jumped timing, and catastrophic damage, typically after 100,000 miles. Despite this, there are no clear warning systems to alert drivers before failure occurs. While timing chains are considered serviceable components, the high failure rate of the timing chain guides and tensioners in these engines, combined with excessive repair costs, indicates a design flaw. I have spent around $4,500 addressing this issue, yet the risk of recurrence remains.

POWER TRAIN

Ford did issue a recall for several issues for my car, including but not limited to, problems when filling gas tank with evaporative purge system as well as cavitation of the fuel pump in high heat conditions, the doors not closing all the way or handles remaining open( not flush with rest of door) when door is shut, driver's side door trim/bezel around power window switch making buzzing sounds when stereo is in use, as well as ticking sounds coming from motor during operation and various creaks and sounds from front suspension when cornering and going over uneven terrain, and the transmission, the 5r55s, has the known hard shift into gear caused by bad servo. I have reached out to the dealers in my area regarding these issues and even though my car is the correct model and year for the service recall bulletins and has the exact issues described there in, I am told that the vin on my car is not covered even though it is clearly suffering from equipment that exhibits all the same problems listed in the recall. I feel the responsibility to perform and pay for these repairs should fall on the manufacturer, not i, the customer.

I purchased this car from Trent Family Auto on May 2, 2024. On September 11, 2024 the engine failed. While working on replacing the engine I found an open recall. This is safety related and was never mentioned to me by the dealership. So aside from selling me a bad "as is" they sold me an unsafe vehicle. A vehicle my family has ridden in several times since the purchase. In regard to the recall when I reached out to them about the engine replacement cost they stated recalls can only be taken care of by manufacturing dealerships. Shouldn't they have some ownership to inform customer buying an unsafe vehicle there is an open recall? Thank your for checking into this matter.

AIR BAGS

Took the 2005 Mustang GT in several years ago to have one airbag replaced. Dealer (Autonation Torrance, California) stated parts were not available for the other side. One of the airbags has never been replaced. I now read there is a "Do Not Drive" recall for vehicles of this year and model in "Zone A".

Body control module. It gets wet when it rains because of an engineering mess up. It shorts out my lights. Sometimes it can't get out of car because it messes with the locks and windows. Can't use my electric mirrors anymore. Instead of being a much needed recall they decided to not even make replacement bcm. It is a problem everything it gets wet that should have been recalled and fixed. At least a thousand other incidents of this happening to others.

ELECTRICAL SYSTEM

I've own a 2005 Mustang GT since the year 2012. Throughout the years I've encountered problems where the cooling fan would abruptly shut off and cause the engine to overheat. The first time this happened I had to pull over to the side of the road countless of times just to let my car get cool enough to get back home. I brought the Mustang GT in to a mechanic who suggested to replace the radiator fan. After replacing it, the fan would work for a few weeks only for it to randomly shut off, but turn back on. Just recently I found oil in my spark plugs and found the following OBD II error codes: P0480 Fan 1 Control Circuit & P0481 Fan 2 Control Circuit. I am convinced the valve seals and maybe the piston rings were worn out due to excessive heat caused by the Mustang's electrical issues with the radiator fan. After searching online, I found countless amounts of threads and videos of other Mustang owners experiencing the same issue. Most of them are caused by a faulty relay connection inside the Mustang's fuse box that is causing the radiator fan to fail. The faulty relay would get burnt and cause a short thus not providing power to the radiator fan which left many owners stranded on the road and caused over thousands of dollars in damages to their engine. The part that gets burnt is not easily available and would require owners to pay an additional thousands of dollars to reconnect the relays. Some owners had no choice but to create a makeshift wired connection from their radiator fan to the dashboard so that their vehicle's engine can remain under normal operating temperatures while driving. I've attached a video of someone explaining this issue at the 8:00 Minute mark. https://www.youtube.com/watch?v=WAs6uf3VV68

AIR BAGS

I have done all my airbag recalls and the light came on a few months ago and is steady flashing. Called Cresent Ford in High Pint and they looked up my VIN and my car replacement history. They told me it had been replaced but it was still under warranty and to make an appointment to have it looked at. Made an appointment, which I may add I had to take the day off and drive 40 mins one way, I was told by [XXX] that I had to pay for a diagnostic test because it may not be the airbag and they refused to look at the car until I paid for a diagnostic test. I continue to receive airbag notices and if I was told on the phone this was under warranty. If there are problems in the past with airbags and in the future, we have problems why should this not be covered and looked at by Ford at cost to them to run a diagnostic test. This is absurd. Had this happened to me 3 months ago I NEVER would not have purchased a 2010 Mustang if this is how you do your customers for your defective parts. Also went to pull the parking brake up, which was passed inspection SEVERAL times, and the brake does not work. This is a BIG safety hazard.

FUEL/PROPULSION SYSTEM

while driving home just as I was switching lanes, the car sputtered badly and a wrench light appeared on dash. Since then, the car did not exceed 20 miles per hour. as I conducted research, a lot of mustangs have this issue and it is theorized to be the throttle body.
