general problems of the 2005 Ford Mustang - part 1

The contact owns a 2005 Ford Mustang. The contact stated while driving 65 mph on a rainy night, the headlights started flickering. The contact stated that upon exiting the freeway, while driving 30 mph, the headlights completely turned off and the hazard lights were inoperable. The contact drove to the nearest gas station and turned off the vehicle. The contact stated that upon attempting to restart the vehicle, the vehicle failed to restart. The vehicle was towed to the residence. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 170,000.

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.

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. . Read more...

The contact owns a 2005 Ford Mustang. The contact stated that during inclement weather, water was entering the cabin of the vehicle through the passenger’s side glove box. The contact stated that due to the failure, mold had developed throughout the vehicle on the carpet, doors, and interior seats. The contact's husband also discovered that water had entered the computer module after inspecting the vehicle and the module was removed. The contact stated that the vehicle was inoperable after several repairs and several battery replacements. The vehicle was not repaired. The contact called the dealer and was referred to the manufacturer for assistance. The manufacturer was notified of the failure but offered no assistance. The failure mileage was 87,000.

Just got it don't know what's wrong with it.

I'm having the same issue everyone else is with their speedometer, tach, fuel gage. It was working fine, the weather warmed up and it would work sometimes. Then it just stopped working completely. I'm afraid to drive the car because I have no way of telling how fast I'm going. I could understand this happening if I had 100,000 miles on it, but as of yesterday, 4/26/2021 it just hit 39,034. With everyone having this same issue, how is not a safety recall. I had to replace the instrument cluster at cost of $875. This is a known issue and a dangerous one.

There is an apparent design flaw in 2005 Mustangs as I have read hundreds of similar complaints as to what I am experiencing. Due to this design flaw after a recent day of heavy rain 1 headlight and 1 signal light will not turn off once the car has been shut off. I researched and apparently the Smart junction box (sjb) got wet and the electrical unit is now malfunctioning. There was also a strong burning smell when I got home that night as well. Spoke with an online mechanic technician and he confirmed that the sjb needs to be replaced. There has been a long history of the car leaking on the passenger side whenever it rains due to the design flaw. Also my gas gauge never reads properly, inside lights are also dim/off and the check engine light has been going on and off for nearly a year and my mechanic could not diagnose why the reviews online said when they spoke to Ford that admitted that it was a known problem but because there has been no recall that they will not repair this for free. Estimates I read put the cost around $1000 to get this fixed and do not want to pay that kind of money especially when Ford admits to knowing there is a problem. I am hopeful that we can get Ford to do the right thing and issue a recall for this. It is a serious problem since the electrical system can cause a fire from reports I have read. This happened to meet on 12/21/18. I was driving home from work and parked the car and shut it off. As I locked the car I noticed that the drivers side headlight and passenger side signal light stayed on and I had to disconnect the battery to make them shut off. Also there was a strong burning odor when I lifted the hood.

The 2005 to 2009 Mustangs (all of them) have a water intrusion problem presented as a design flaw in the engine firewall that leaks water onto the Smart junction block causing random electrical systems failure including the loss of engine ignition, loss of all systems, etc. In my case, the intrusion of water caused a sudden and complete loss of all systems. Discovered a day after heavy rain. There are thousands of reports of this on the web and the dealer admits it is a design flaw and known problem.

My instrument cluster does not work and Ford needs to have a recall with all the complaints with all the 05 Mustang owners.

Ever since I got my Mustang the fuel gauge was acting up and would sometimes give me a correct reading but most of the time it just sits at empty even after refueling. Then just recently I started driving into work when I noticed that my speedometer said I was doing about 100 mph on city streets and confirmed it was inaccurate when I came to a stoplight and came to a complete stop but the speedometer read 50 mph. When I got to work I stopped the engine and started it back up and I had to repeat this process 7-8 times to get it to reset back to 0 mph this was the first time that occurred since I got it.

I purchased my 2005 Ford Mustang v6 automatic transmission in July of 2016. At the time of purchase everything seemed to be working fine but about a month later I noticed the fuel gauge was sitting at e so I attempted to fill it thinking I had an empty tank which meant I should have been able to put 14-16 gallons in and as I was refueling I noticed it kept shutting off even though I had just started the pump eventually I got it filled and only put in about 6 gallons which I thought was odd but I went with it and got back in my car started it up and noticed that the gauge was still sitting at e at that point I knew something was wrong but I figured it could wait since I knew how far I could potentially go on a full tank but then after I left and headed for home I noticed that my speedometer said I was going 60 but everyone was blowing past me at least 10mph faster when the speed limit was 60. So I pulled over and noticed that at a stop the speedometer came to rest at 35mph I was able to fix it but it kept happening I was lucky enough that I didnt get pulled over because I had no idea how fast I was going. Then for a while that stopped happening but every now and then and at an increasing rate the engine keeps stalling like its not getting enough fuel when I stop at an intersection or stop sign even though I had just filled the fuel tank the day before and hadn't driven more than 50 miles. The mileage at the time of the incidents beginnings was ~24,000 miles the current mileage is 34,000 as of 5/15/17.

This 2005 Mustang was bought used about a year and a half ago. Within a few months we noticed the messenger side floor would be wet when it rained. Soon after the speedometer quit working. The extended warranty did not cover the repair. A few months later the heat and air control unit went out. These two repairs cost over a thousand dollars to fix. On October 102015 while at the drive up teller at a bank the car would not come out of park. Tried shutting it off but would not restart. Seemed to have complete electrical failure. No lights gauges or anything electrical would work. It was raining. After jumping the car several times we were able to get it home. We inspected the ecu and found green and white corrosion indicating water had been getting inside the box. When I called Ford they took a report but said they would not fix the problem unless there was a recall. There is a technical service bulletin issued TSB 07-14-6.

Entire instrument cluster stopped working except for digital readout. The interior floods with water when it rains.

Speedometer not functioning. While driving 30mph will register as 50mph or while driving 60pmh will register as 120mph. Emissions trouble light will periodically go on.

Exiting the highway I 93 and entering I 95 s, there is a relative sharp corner to turn. Both my speedometer and tachometer showed incorrect speed and rpm and made me believe I was slowing down to a safe speed of 30 mph. However these gages were not working and I was struggling to make the corner. I have had issues with the fuel, oil pressure and water temp gages not working, but with tachometer and speedometer not working reliable I believe that it is not safe to operate the vehicle. As a precaution, I am using my nevigation system to know what actual speed I am going. Looking at the internet, I am finding lots of people complaining about the dial stepper motors not working correctly. It is a costly exchange of approximately $ 600 + labor and with Ford knowing of the malfunctioning gages and not warning consumers is really unacceptable to me. These clusters should be replaced at Ford's expense and not at the consumer's. These gages were designed to ensure safe and proper operation of the vehicle.

. I got in my car an started the engine. I then noticed my fuel gauge and speedometer were not working at all. I have always taken care of my Mustang an I think Ford should recall the cluster. There's been plenty of 2005 models with very same issue. Please recall the gauge cluster it's the right thing to do for a big name company like Ford. Original owner.

The speedometer were not working at all. I read in very forum that 2005 models with very same issue. Think Ford should recall the cluster. I read this in other complain and my opinion is the same. "please recall the gauge cluster it's the right thing to do for a big name company like Ford. Original owner".

Gauges don't work properly. Can't tell how fast you are going, what your oil pressure is, how much fuel you have etc it's a safety issue.

They get stuck especially in cooler weather. The tach is now stuck hanging in the down position. The odometer can go anywhere from 20 to 40 mph faster than I am going. When stoppef it will be in that position.

Tl-the contact owns a 2005 Ford Mustang gt. The contact stated that while the vehicle being serviced at a dealer, the technician discovered that the a/c emitted a harmful gas into the cabin. As a result, the contact sustained sensations of lightheadedness, severe headaches and heart palpitations that there required medical attention. The dealer advised the contact not to activate the a/c to avoid further health issues. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 38,200. Djr.

The speedometer on my Ford saleen Mustang 2005 recently has stopped working properly, the needle on the speedometer sits on 10 mph when idling, when I accelerate the needle is off by 10 mph, this is a safety issue, not knowing how fast you are traveling. I have looked up if there are any recalls available through the web and have only found similar issues on forums.

Instrument cluster (panel) - speedometer, tachometer, fuel gauge all not working. Can't tell how fast I am going or how much gas I have ect all 6 gauges do not register at all.

Speedometer and tachometer needle does not function correctly. Speedometer does not move half the time from resting position and the tachometer will rotate all the way around and stay where it is when the car is turned off. The battery, oil, and temp needles do not move from off position half the time. Transmission does not shift smoothly and shifts harder going from second to third.

Since about a year ago, November 2013, this vehicle has shown multiple issues. To start, it is an automatic 05 Mustang which, the more I read online, the more that I seem to find that many have these exact same or very similar issues. Initially the dash cluster (everything besides the tachometer) was not functioning properly. The speedometer would get stuck at 20 mph but still move acting as though the 20 mph was the 0 mph mark (so 35 mph = 15 mph). More recently the gas gauge has stopped working, it sits at empty even after plenty of gas has been put into it. The temperature gauge also gets stuck often, still moving as the speedometer does. Not too long after these issues started occurring, when I went to fill up the gas tank it wouldn't take the gas as it normally would. Sometimes only a couple dollars worth would be in before it clicked off. After paying closer attention I have also noticed sometimes gas actually splashes out when filling it up even though it is definitely not full. Much more recently the vehicle has has worrying issues. At one point while driving on the freeway at 70 mph the vehicle suddenly started to decelerate on its own, even while I was pressing on the gas pedal. I pulled it off to the side, shut it off completely, started it up and it was as though nothing happened. Ever since that incident though it has been running a bit louder and now it seems a possible misfire is happening with one of the cylinders occasionally. The vehicle has a delayed and very hard shift from third to fourth gear. It is not as though the vehicle has not been taken care of, and for a 2005 the mileage is pretty low still. At least one or two of these issues seem to be a safety concern, and it is very obvious after researching online that these issues are prevalent in tons of these exact same vehicles.

After the leaving the car turned off for approximately 1. 5 hours my two teenage daughters, age 17 and 15, got in the car to drive home and noticed that the car smelled a little smoky. They drove down the road for about 5 minutes when the electrical panel went dead, then the power locks began to go up and down continuously and the smell of smoke became more prominent. At this point, they became very concerned that they were going to be locked in the car with smoke pouring out and not be able to get out of the car. So they pulled into a parking lot, immediately exited the car and called 911. As soon as they got out of the car, smoke began billowing out of both doors which were left open. 5 minutes after exiting the car, flames which reached two feet high, began coming out from under the glove compartment. A passerby obtained a fire extinguisher and tried to put out the flames, then the fire department arrived and proceeded to put out the fire completely. The fire department indicated that it was an electrical fire but were not able to determine the source. They indicated that they thought the vehicle was totaled, which was in fact the case. Clearly, this was a very upsetting situation for our entire family. We feel blessed that the girls were able to get out in time, but also upset at the thought of what could have happened had they not acted immediately or were not in a position to do so.

2005 roush Mustang gt sport. Manual transmission. Only 24,000 miles. Collector condition. Instrument cluster issue. Tachometer stopped working. Fuel gauge intermittent. Temperature gauge intermittent. Speedometer still working.

While travelling, the speedometer indicated speed changed from 60 mph to 125 mph. It now reads 65 mph when stopped, even while off, and seems to always indicate actual speed plus 65. There is no way to determine actual speed.

Since the car has had around 45000 miles on it I began having intermittent electrical issues. Speedometer, wipers, instrument cluster, break lights, head lights, and blinkers all stop working while driving. I am forced to shut the ignition off while driving and recycle the key just to get the blinker work and then shut it off again to turn it off! doors will no longer lock or unlock and cannot pop the trunk using fob. The electrical panel on the floor of the passenger side is clicking and I have read hundreds of complaints on the internet about this water leakage issue. How many people need to die before someone holds this manufacturer responsible? this has been a known issue for over 8 years and nothing has been done. Does someone need to be killed when my brake lights fail to illuminate before you take action?.

My fuel gauge, car temperature, and speedometer, all of a sudden started reading all over the place. The fuel gauge goes way past the full mark. The temperature gauge goes way past the hot mark. The speedometer always reads 110 mph.

Water got to fuse box made headlights go off and flooded passenger side of car.

The contact owns a 2005 Ford Mustang. The contact stated while driving 50 mph, the speedometer stop working without any warnings. The contact mentioned that the speedometer was reading 0 mph when the driver was traveling approximately 25 mph. The vehicle was not taken to the dealer for diagnostic testing. The manufacturer was made aware of the failure. The vehicle was not repaired. The failure and current mileage was 26,865.

Dash board gauge stepper motors are faulty resulting in no speed registered. . . No coolant temp registered. . Improper/no fuel level reading. . . Incorrect/no r. P. M. Readings. . . Upon start up, the gauges go ,for lack of better word, crazy. . Or dont operate at all lots of Ford Mustang owners are expweriencing this issue>>>> dangerous to not know the speed rpm fuel level and coolant temp. . . . Could result in accident, vehicle damage. . . Or worse!! Ford needs to be advised to recall and fix this issue. . . .

The instrument cluster on my 2005 Mustang is failing. The rpm (tach) does not work at all. My temperature gauge does not work at all. My speedometer is starting to fail. I have researched and found this is a common problem w/ the 2005 Mustangs, yet there is no recall. If my car overheats, I will never know it. When my speedometer finally fails, I will not know how fast I am going.

Drove not knowing how fast I was going except my gps thank god, airbag said malfuntion popped me in the face, lights were dim couldn't see and drove into a pole. Third huge issue and Ford won'r fix b/c warranty I could have killed or been killed.

I curretly own a 2005 Mustang gt. I have several issues with my guage cluster on my car. Speedometer is stuck at 40 mph, fuel guage doesnt work, temp guage works when it wants to, oil guage isnt reading correctly low fuel light comes on when I dont need fuel. I contacted Ford about the issue and they were no help. This is a safety concern. I dont know how fast im going. I dont know the temp of my motor. I dont know how much fuel I have. I have googled this issue and it seems that over a hundred other 2005 and 2006 Mustang owners are having this same issue and Ford isnt helping anyone. Ford should step up and help us Mustang owners with these issues.
