A D V E R T I S E M E N T S

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.

My Mustang has been doing this more frequently now, where I'm driving highway speeds and the transmission suddenly downshift to low gear from high gear. This afternoon it almost caused me to crash on my way home from work on the freeway. This is completely unacceptable and life threatening. I went on google, to look up if others are having this same issues and I came across a lot of Mustangs of this year have the same exact issue. Matter of fact, Ford is aware of this issue but why hasn't a recall been put out to fix this transmission problem. A lot of lives are at danger and accidents to occur due to this problem.

Transmission gear selector indicator is faulty. It does not indicate the correct gear when driving. For example, the gear is in reverse but the indicator is showing parking. It creates confusion whether you are in right gear or not. Especially I thought you are at P when you are in R.

After putting the vehicle in drive and application of the gas pedal, the transmission would fail to engage first gear. This occurred intermittently and occasionally while driving. The transmission would also downshift to first while driving at 35mph. Brought to Ford and they identified the lead frame and connector as faulty parts. Ford has a recall 16S19 that covers my Mustang's build date and location but said my VIN wasn't included despite the exact same symptoms and exact same parts identified by a Ford technician that needed to be replaced. Ford the customer service refused to cover the repairs to a dangerous condition.

Over the past couple of weeks, the automatic transmission has had a mind of its own. It has downshifted into first gear on its own from different gears, it has stayed locked in gear on several gears and it has stayed in a high gear while stopped, so it is very slow leaving a light. This happens intermittently, but it has happened approximately 6 times over the past couple of weeks. No trouble codes or lights (mil or wrench) have been thrown or lit up during the incidents. The car seems to right itself after a few minutes. Happens mostly when the car has been sitting for a long period and is cold. Took the car to glenn Ford in nicholasville, ky and explained what the vehicle was doing and if it was related to the recall that they performed (16N02/16S19) on the car back in Feb 2017. They brushed it off and said it would be $110 to look at the car. We said fine. They have held the car for 6 days and said they drove it at least 36 miles and "nothing happened". they said there are no dtc/fault codes, so the car is perfectly fine. They said they will not perform the molded leadframe repair of the recall because there are no fault codes. I called Ford customer service complaining of the situation because the info on the notice says either a fault code shows up or the customer "reports an intermittent unintended downshift into first gear". well, that is exactly what we reported before we even realized anything about the leadframe part of the recall. Both the dealership and Ford have refused to fix the vehicle unless there is a default code/dtc showing. They want us to drive the car until a fault code shows (thus possibly endangering our lives) and then they will look at it again. Doesn't mean fix it, just look at it again for another $110. This is completely out of line. Ford won't even fix it under their own recall instructions!!!! and the car qualifies!

Shift solenoid D : veh is part of recall 16S19 and recall 16N02. The vehicle is shifting still at without warning at various speeds. This device was not included in the original recall, and Ford is refusing to cover this defect although it is clearly a part of the same problem. Ford had ordered these transmissions from a manufacturer in china, and they've been nothing but trouble from day one. This occurs while the vehicle is in motion and there is no warning when the malfunction occurs. The car was sold to me this way in February of 2013, and at the time the dealership had told me that this was an open ECM issue and was nothing to be concerned with. I took them at their word and am paying the price for it. I have checked my car fax, and there is absolutely no mention of this as a problem. Now, I am getting a code P0769 read more: Https://www.engine-codes.com/P0769.html this is a safety issue and Ford is saying they do not and are not going to cover this under the recall notification. As a former paramedic, with experience with countless motor vehicle accidents over the years, it is my professional opinion that this is a potential hazard to life, limb and property and a recall should be ordered.

At wide open throttle the transmission will not allow a gear change from first to second if the RPM is grater than 6000 RPM. The clutch peddle releases at the floor. After the engine has slowed the clutch returns to normal and the car can now be shifted into second. It may be caused by trough out bearing or spring tension on the clutch its self. I have had this problem since I bought the car 3 months ago. The car only has 46000 miles on it. I have read other people have had the same common problem.

Front hood has paint peeling issue within 2 years of purchase. Auto trans doesn't shift properly in at least 1 of the first 3 gears. It bucks when cold in winter weather until car warms for at least 30 minutes.. Ford has had the car on 3 occasions without fixing the issue. They replaced the first 3 solenoids in trans without success. Purchased new. These 2 issues remain a big problem. On another note, interior cabin flooded due to rain entering the cowl from a design flaw. Dealership detached a hose.

Since I've bought this vehicle brand new I have had random issues with the car. First I've experienced a huge issue with the transmission, it makes a vibrating/shaking problem while driving on any street any speed. I have operated manual transmissions before and have never ran across this. No matter what gear or what condition it consistently does this. Ford dealer was to no help at all. At times while driving the vehicle will start to uncontrollably swerve and the traction control light starts blinking, this issue is unknown to me why this happens and has almost put me in an accident. Secondly, the entire ignition tumbler just popped out. I can pull the ignition out of the steering column.
