Vehicle has less than one year since it broke down last and now I have another problem. The secondary timing chain tensioner has failed and lead to secondary timing chain failure broken rocker arm and maybe damage to the piston it has been problem after problem this car is a lemon and this needs to be addressed I was driving through and intersection and my car stalled luckily it started once more just long enough to get it off the busy road. There was bolts on the valve cover that's weren't even drilled through the plastic valve cover. There is no reason a fairly new motor should have malfunctioned like this.

2011 ford mustang 3.7l v6 convertible, premium, automatic transmission throttle body failure (part # at4z-9e926-b) while driving, the car suddenly decelerates, the dashboard 'wrench light' comes on, the front end of the car rumbles and shakes, and the car will not accelerate, forcing me to pull off the road. This happens at moderate speed on local roads and at highway speed. If I pull off the road, turn the car off, wait a few minutes, and then restart, it usually runs normally. On one occasion, it did not. It decelerated and then stalled completely in the middle of a four way intersection while I was on the way home from the dealership after being told there 'was no code,' so they weren't able to do anything about the problem. I coasted through the intersection, pulled over, turned the car off and then restarted it, after which it ran for about a minute, shook violently, and then stalled. Every indicator on the dashboard was illuminated. It seemed as if the car was choking. I repeated this over and over, creeping down the shoulder, back to the dealership. In my case, this part has been replaced three times in the last five years, most recently on oct 29, 2019. According to my service records, part # at4z-9e926-b was used for each replacement. Apparently, ford replaces a defective part with another defective part. This part should be recalled and replaced with a different or improved part that will fix the problem once and for all. 2015: code p2135, replaced throttle body assembly 2016: sent away from dealership, no fault codes, unable to verify 2016: returned to dealership shortly after I was sent away; code p0315, replaced throttle body assembly 2016: customer satisfaction program 16b23, reimbursed for throttle body replacement 2019: no fault code noted on service paperwork, replaced throttle body assembly

Engine stalled while driving several times (once on a city street and twice on the highway). On other occasions the car would hesitate to respond to the accelerator. Mechanic scanned the computer and found code p2111 throttle actuator control system stuck open, and determined the cause of the problem to be the throttle body.

Driving in city @ 35mph, went to accelerate and nothing happened. Thought engine stalled but still had ps & pb,s. Called local shop, said to turn off & restart. Did and throttle returned. Two days later, happened again, on county highway @ about 60 MPH. Pulled over, turned off, restarted, went to local shop. No check engine light or wrench ?? Light came on. Computer test all negative,but probably a bad electronic throttle body needed @ $ 500. + . Took car and got on line, not going to spend $ until sure of exact issue. Found the federal safety agency csp 13n03 , addressing my identical issue for 2011 fusions & escapes with v6 engines, but haven't found for 2011 mustang. This extends warranty to 150,000, and 10 years. I have 109,879 miles now, and issue happened twice today on interstate @ 75 MPH. Popped to nuetral, killed key, restarted on roll both times.after parking car for short while and restarting, check eng ine lite on. Went back to shop & re-tested, this time, throttle body and associated issues dignosed. Since this is obviously a safety issue that is well documented on other models, I need to have my issue treated equally. What can you do to help?? Humbly, melody & kenneth pitts

My 2011 v6 ford mustang has now stalled several times going down the road. Has happened at both high and slower speeds. After pulling over and waiting a few minutes, car starts and runs okay until the next unexpected stall. Repair shop revealed no codes. Very dangerous problem!

11/14/2014 - vehicle engine appeared to stall or shutdown (no power) with "wrench" displayed while exiting highway. Coasted to shoulder and restarted vehicle mileage approx 32,100. Re-occurred on 12/9/2014 while traveling on highway at 70 MPH - was able to coast to shoulder and restart. Ford dealer ran complete diagnostics next day but could not identify a problem. Vehicle mileage less than 33,000. Occurred again on 1/27 on highway while traveling on highway at 65 MPH - coasted to shoulder and plugged in obd-ii diagnostic tool I have been carrying which displayed p2111 throttle actuator control system stuck open. Restarted care - occurred again 2 miles later this time - same code reading - and now check engine light also on. Vehicle mileage 34,650. Dealer replaced throttle actuator control on 1/28/15 at my expense (not under warranty / no manufacturer recall). This is a significant safety hazard - unexpected vehicle shutdown occurring at highway speed.

This began as of last thursday. I have a 2011 ford mustang that I bought just last august. As I was driving on the freeway, a wrench light came on and my car seemed to have stalled on me. I thought maybe it was because it was pouring down raining so I was able to pull over into a parking lot since I was exiting the freeway. I turned off the car after it seemed to vibrate a bit, waited a few moments, turned it back on and it seemed fine. I was able to get home and park it only a few miles from where it happened. I had a doc appointment later that day and was able to get there. It was when I was on my way home that it happened again, on the freeway! It occurred again the next day (friday) as I was leaving from work. I was on the freeway again in busy traffic and it happened twice except the second time, my engine light came on. My dad took it to a mechanic, it was hooked up to the computer and no code came back. Coolant was put in it and the engine light went off. The throttle body was cleaned. Everything was fine afterwards. Today, I'm driving to work and it goes into limp mode twice on the freeway while drivers are swerving around me! This is not safe at all! I have extended warranty on my car so this is going to have to be fixed asap. To anyone else having this problem, please be careful. Once it goes into limp mode, your speed will drastically decrease and you will not be able to accelerate. It is scary because not all parts of the freeway have a shoulder to pull over...this needs to be a recall before someone is seriously hurt. I've read up on other owner's issues and saw that there have been quite a few wrecks behind this.
