Shelby GT350 5.2L V8: Engine oil filter spins loose, causing catastrophic loss of oil. Street use only, no track days. Car dealer serviced only. Dealer denied fault, said oil filter coming loose was "normal" for this model.

Vehicle shut down 2 times, once in traffic, did restart, seemingly because of low system voltage caused by a parasitic draw on the battery which has been present since new. Multiple dtc's in history which I can supply, Ford of course knows nothing, but I have seen many complaints on web pages about S550 battery draw.

Started my car this morning and as I was backing out, I noticed it was idling roughly, causing the car to shake. When stopped, the car felt like it might die and the RPM was inconsistent while accelerating and the car was moving. Very rough riding. Also, engine light came on and begin blinking.

Driving on the dallas, tx highway 35- rlthornton headed sound in the peak of traffic in the fast lane (far left hand lane) going about 35miles and car stops. My feet was pressed on the acceleration but the car would not move. No engine warming or lights came on. The cars behind be began to swerve and brake to keep from hitting me. The abrupt engine shut off could have caused accidents or even worse fatalities. (my life) because the car was unmovable and failed to start, 911 had to be called for assistance with getting me out of arms way of other drivers and on the right side of the highway. I called the dealership, to inform them of the matter. Had the car towed at the expense of $120 dollars. 2 days have passed and my car hasn't been looked it. I was told that they might get to my car by Friday, 8/31 and that no rentals were available. My biggest concerned is the safety of my life and others. After researching around it appears that others have also experienced this problem. The Mustang is Ford biggest seller but consumers have the right to know of any issues such as this being reported. Why, because lives matter.

The power went out while the engine was running, while moving steering wheel froze, ,took to have fixed and power train was damaged from repairs but told it was fixed, but the dash screen keeps going out. Now 3 recalls 2 for seatbelts, front and back, and the cooling system is being recalled for a hose or system malfunction that could cause a fire. Already had the air assembly fixed, now this latest recall. All around this is an unsafe car to drive, it only has 11,000 miles on it and it has had major defects and sever things go wrong. It's a lemon

On 4/28, 2018 while driving on Florida's turnpike at 65 mph without warning the car decelerated and lost power, going into limp mode. Luckily no accident happened, but clearly a serious safety issue.

Rear differential traction control clutch pack failure

- Claremore, OK, USA

Car in motion; on 10/09/2017 - I was driving 80 mph (which is the legal speed limit), on major Texas highway 130 toll road, engine stalled, car hard to control, difficult to pull off the road to safety. Attempted to restart car several times, after 7 or 8 times it finally started. It had a rough idle, and continued to stall out 6 more times for the remaining 30 miles until I reached my home. There are no stores, or safe places to pull off of the road on this toll road, and it is a very long stretch of highway to be left stranded on. I've contacted Ford service and they said there is nothing they can do, my car is a 2016 Mustang which I bought brand new...

The contact owns a 2016 Ford Mustang. The contact stated that while driving at various speeds, carbon monoxide entered the vehicle through the air conditioning vents, which caused the contact to have headaches and nausea. Medical attention was not required. The vehicle was taken to the friendly Ford of crosby dealer located at 2425 us-90, crosby, tx 77532; (800) 568-9561 where the gas kit was refilled. The contact stated that the dealer was unable to diagnose the failure. The contact stated that the odor was getting worse every day. The vehicle was not diagnosed or repaired. The manufacturer was contacted at 800-568-9561 and was made aware of the failure. The manufacturer informed the contact to take the vehicle to the dealer and a case number 12966085 was provided. The approximate failure mileage was 22,835.

- Crosby, TX, USA

Purchase date 4-16. Eight documented visits to dealer/repair. Other visits where service adviser said to return when system failures were happening, as problem would resolve before I arrived at service. Re water inside, driver door issues, sync, camera/stereo electrical issues include doors will not unlock at times, takes multiple attempts to be granted access into car, thus causing safety concern. Sync goes out fairly regularly including phone function, back up camera, stereo. Currently in shop again since 7-3-17 @ 9 am.(16 consecutive days this trip). Safety concern of most importance to me is the fact that car has lost power multiple times on highway and thankfully has not yet been in a major accident. Quick reflexes of drivers behind me are only reasons that accidents have been avoided thus far. I am told by dealer that this is a throttle body malfunction. Throttle body has been reprogrammed after a near rear end accident ( highway/ intersection/turn). Throttle body went out with no warning car instantly decelerated with no acceleration capability. One week later throttle body fails again causing a near accident that would have been fatal in nature due to the speed of traffic on highway. My 7 yea old was in rear seat. My children are no longer for any reason allowed in the vehicle since October 2016. Throttle body has yet again been replaced June 2017. Third attempt to repair this car with no indication that this is a repair, it seems to be merely a repair attempt as this process of attempted repairs has caused 3 near rear accidents. This car has proven itself to be a danger on the road and a major safety hazard for anyone inside or outside of this vehicle while it is in motion. Low mileage is indicator of how untrustworthy vehicle is to me. It is only driven by me, no passengers allowed. Only driven if another car can not be borrowed. Unresolved issues.

Takata recall. The issue with my car is that the engine is shutting off while coming to a stop. Whether the clutch is engaged all the way or if it's just in neutral. Suddenly the RPM's just drop to zero and I would have to restart the car again by hitting the start engine button. This had happened multiple times in the past few couple of months. Other than that the car still runs smooth and everything else is fine. I have almost 18000 miles on it. I really hope Ford could figure out what the problems is.

Engine oil cooler tube assemblies leak brought the car to the dealer twice problem not fixed, yesterday 4/12/17 brought the car again for the same problem, the service department is saying the coujld not finish the job today and wants to keep the car over the weekend for further repairs. We paid good money for this car, we want to use the car instead of having the car I N the repair shop!

- Mcallen, TX, USA

Rough idle with no throttle control while in drive. Engine died and wouldn't restart. Was taken into Ford for similar problem a few months ago and I reported it here. The first repair was recorded as a defective throttle body. This car is not safe!

- Surprise, AZ, USA

It has a little over 5000 miles on it and it is using oil excessively. It is using a quart of oil every 600-900 miles and is getting worse. I have brought in to Ford twice. Both times they said I would need a new engine. But, I just received a call from them last Friday on 10-21-16 and they said they are not going to be putting a new engine in the car as they fear the new engine will do the same thing. They said they "may have a fix next spring." I called Ford customer service and their regional rep called me back. She only offered me a maintenance plan for free oil changes. This is worthless to me and my current problem as it doesn't need oil changes and does nothing to address the problem. Since they admit they have a problem with the engine and have no repair for it, I asked them to buy the car back. They refused.

I bought a new 2016 Mustang in April. I was driving uphill at 40 mph. All of the sudden the engine cut off. When the engine went off a large wrench came up on the display and it said see manual. I tried pressing the start button but it would not start. I had to come to a complete stop, put the car in park and then was able to restart it. This could easily lead to death! if this would happen on the beltway or I-95 I could get killed. The car didn't overheat and all the gauges showed normal. Now I am afraid to even drive it; I don't want to be killed or kill someone if the engine stops.

The car suddenly lost power and no acceleration was possible. The trouble light came on. Car would only roll at 10mph with engine power. The gas pedal would not control the motor speed. Car would not shift. This happened when I just pulled in to a parking lot. I was able to use the emergency flashers to get the car home using side streets at 10mph. Last year a guy in his 2015 Mustang asked me if I had this problem as he explained the same situation when I also owned a 2015 Mustang. I didn't have that with the 2015, but I just bought it when we talked. I know what he means now. As my 2016 did what his 2015 did with a loss of power.

- Surprise, AZ, USA

During normal driving during 5pm traffic, the car shuddered, a wrench icon came on the screen, the car lost power and would not accelerate. The vehicle was in motion at the time on a 4 lane road with multiple other vehicles in close proximity. After pulling over and shutting the engine off and on 2-3 times, I was able to drive approximately 2 miles to dealership. Service department seems to think it is a defective electronic throttle body.

- Ridgeland, MS, USA
