Problems with 2005 Ford Mustang ELECTRICAL SYSTEM

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 ...

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.

I purchased my car new march 1, 2005. i have done all of the suggested maintenance through the dealer. in 2011 - water pouring in under dash front passenger floor. i took the car to the dealer and they couldn't find the leak. i started to wet vacuuming the water out. then the car started to smell like mold. i finally called my nephew who works for ford in another city. he cleaned out the drain in front of the passenger side and dried out the car. why didn't the mechanic at landmark know about the drain? around this time the car started to lock and unlock itself while parked in the driveway. called dealer no help. called nephew he said wiring issue. the locking and unlocking stopped. since then the locks try to relock anytime i accelerated from a full stop. i have found my windows rolled down. i never leave my windows down. i am a big stickler when it comes to locking my car up and i don't leave my windows down. it happened again this last week. next came the trunk. it ...

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. *tr

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 ...

Had the airbag replaced/ weeks later had the "faulty seal" problem followed by the "sjm " box (smart junction box) destroyed by the water damage due to faulty seal. now the sjm is on backorder until aug. 2016. seal already replaced in march/2016 when order placed for sjb. researching the problem there are thousands of complaints regaurding 05-07 mustang models. due to make design. unfortunately, resulting in window motor failure, battery drain, headlights stuck on high beams, turn signals stuck on, insturment cluster malfunction and dash lights fail. i have searched for any recall information and civil suite/ class action. the dangers and the numbers are clear, ford needs to be investigated on this matter. the ford customers deserve to be compensated for their losses and damages. especially in the case of individuals whom are waiting for the sjm box to be manufactured due to shortage of materials.

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

Defect in under cowl drainage leads to rainwater leaking into passenger compartment. water drains down wiring harness into the smart junction box casing electrical shorts that at first caused the right headlamp to shutdown after 15 seconds. recycling the headlight switch brings the headlight back on for another 15 seconds. this condition renders the vehicle unsafe to operate from sunset to sunrise. now the drivers side headlamp has begun the same problem. i checked online and it is apparent that this is a significant safety issue for which the vehicle manufacturer has no part available to fix. they initially informed me that the smj would be available to purchase last september. that has now been pushed back to february of 2016. they want over $400 for the part plus additional labor to program and install a component that should have been recalled years ago. this problem is already covered under a tsb and the defect can cause a multitude of malfunctions that could easily result in life threatening situations. i just recently checked and found over 286 reports on file with nhtsa, yet no apparent investigations appear to have been ...

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 stopped it will be in that position. *tr
