Transmission seems to lose power while driving, the car will barely pull itself but the rpms increase if I accelerate. This has happened several times while driving and occasionally there are dash lights lighting and speedometer/gas gauge doesn’t work but that doesn’t happen every time. When it happens I pull over and shut it down and restart and it runs correctly until it happens again! I do a lot of highway driving and the car just “falling flat” on a multi-lane highway at 70+ mph is definitely a safety issue! I have taken it to my local fastlane shop and the car was driven but didn’t malfunction at that time. He advised me to try to drive it there if it happened again, but I have never been close to the shop at the times it happens or they are closed. There is no advance warning, it happens at various speeds and even on takeoff after stopping for traffic lights. I once was pulling into traffic when it happened and didn’t have enough power to get to my lane before it fell flat! Fortunately I could back up before getting hit by oncoming traffic.

The contact owns a 2013 Ford Mustang. The contact stated that while driving 50 MPH, the transmission downshifted, and the RPM was elevated. The vehicle then shifted into LIMP Mode and drove erratically. The contact stated that several unknown warning lights were illuminated. Additionally, the fuel gauge was indicating that the fuel tank was empty however, but there was fuel in the tank. The contact stated that the speedometer showed the vehicle at 0 MPH while the RPM was elevated. The vehicle was taken to the dealer; however, no failure was found. The manufacturer was made aware of the failure and referred the contact to file a complaint with the federal safety agency Hotline. The failure mileage was approximately 90,000.

Indicator light check engine with fluctuating or inaccurate fuel levels. This could lead to a stall while driving and/or an inability to restart the vehicle, which can increase the risk of a crash.

I bought my 2015 mustang premium edition with 200 miles on it in 2016. During the last few years, there have been numerous times when the engine has shut off while driving, and stalled twice while waiting at a light. It goes into aux mode. But restarts right away I have not had the problem for quite some time but this past saturday, it shut down again, while turning and this time a light came on that said run power active. This is a serious and dangerous condition which happens randomly, but usually while turning. Fuel level was 1/4 this past time. Ford must find the cause and recall asap. It has never happened while parked to date. Only 6600 miles on the car. Similar reports are posted on this site.

I was driving a county back road with nobody in front or behind me. The vehicle is an automatic and it was in overdrive as my speed was approx. 60 MPH. Without warning and without me touching the shifter, the vehicle suddenly downshifted into 1st gear locking the rear wheels until my speed was reduced and they began to roll again. I never lost control of the vehicle but it scared me to death! There was light up wrench symbol error warning. The dash turned red and all speed, fuel level and mileage was blank. I put the vehicle in park and made sure it was engaged. I pulled the emergency brake on and shut the ignition off. Checked the transmission fluid which was fine. My mustang was made in january 2012 at the flat rock assembly plant. As I began my research, I found the ford recall 16s19. Which described exactly what happened in my situation. When the dealership called ford for approval, they said my vehicle was not affected because my VIN was not showing it as an exposed vehicle. It manufacture date, assembly plant, transmission type all match but somehow my VIN was not showing. I paid $950 out of my own pocket for the exact repair this recall called for. Which corrected the issue. How in the heck is my car not covered when I know it had the same transmission molded cover issue... Please help me. I can provide my repair records to show it was exactly the repair procedure the recall recommended.

The speedometer, tachometer, RPM, gas gauge and probably cool/heat gauge aren't working. I see a lot of people complaining of the same issues with the model year online. What can be done to fix them? I just bought the car yesterday and spotted it as I was driving car home

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.
