Approximately 31,000 miles but warranty has expired due to lapse of time - he A/C has failed due to what the dealership called a known issue; however, even though mileage would still be under warranty because the car is greater than 3 years old they will not cover this costly repair

While coming to a stop with the clutch pressed in the car will randomly turn off intermittently. This has now just began happening, although it has now happened to me twice in 1 months time. I have also been reading on S550 Mustang forums (years 2015 - present) that I am not the only one experiencing this. It seems like an electrical issue or something as there are people with completely stock cars that are affected by this, and also people with 2018+ newer Mustangs as well.

Evaporator core leak

Ac has stopped working... again! car has been repaired twice under warranty. Now out of warranty because of age. Car has 23K miles 2 times full refrigerant charge has vented to atmosphere, a violation of federal law! thousands, if not tens of thousand Mustangs are affected

This model has known issues with the A/C system. A defect in the evaporator core causes poor A/C performance, for which there is a posted tsb. I believe there is potentially a safety issue here which would warrant a recall. Since the refrigerant leaks into the cabin from the evaporator core, the windscreen forms a residue which obstructs driver visibility, especially when there is glare from the sun. Driver visibility is a factor in the probability of automotive accidents, therefore the commonly defective A/C system directly impacts the safety of this model. To maintain performance of the A/C system, it must be topped off. But visibility suffers and the windscreen must constantly be cleaned. Another safety issue is that refrigerant that is leaked is chronically inhaled by occupants of the vehicle. I'm not sure about the toxicity of R134A, but I can't imagine that it belongs in peoples lungs. If is it dangerous to do so, then I must reiterate, the commonly defective A/C system directly impacts the safety of this model. I sincerely hope that this issue gets more attention and a solution is proposed. Thank you and best regards.

Air conditioning is failing after 60,000 miles. Suspect it is the already well documented evaporator core going bad.

I have a 2016 Mustang convertible eco-boost which is just recently started having a problem with my passenger door opening while going down the highway. The first instance happened a couple of weeks ago and the last one happened last week on July 22, 2020. The sensor system in my car did alert us that the door was open. I have read on the news that the Mustangs are being recalled for this problem but when I checked my VIN I see no recalls on my vehicle. Can you please tell me how I can get theirs repaired under a recall since it is happening to my vehicle. Please contact me if you have any questions. In the first instance we were coming to an intersection and was slowing down for the stop light. The second instance we were going down the interstate at 65 mph. We had to go into the breakdown lane to shut the door. In the first instance we had the top down and in the second instance we had the top up and the windows rolled up.

The ac in my 2016 Ford Mustang has stopped working and I have researched online to find that many 2016 Ford Mustang owners are having similar issues. My car is just out of warranty and only has 20,000 miles on it yet is having this major issue.

The evaporator core on my car has a leak and needs to be replaced, out of warranty and with only 4000 miles on it, for $1800. This is not an isolated incident; forums around the internet are filled with hundreds of pages of consumers with identical stories. Ford has issued a tsb acknowledging the problem (tsb #: tsb18-2166, NHTSA id #: 10143077), but has not issued a recall or buyback program, despite the fact that thousands of cars are leaking R134, a toxic chemical and environmental safety hazard, into the air. This is especially true if consumers don't have the spare nearly $2000 to spend on replacing the core, meaning the old one will continue to leak indefinitely.

Mustang's doors open while driving in motion, on a city street and highway. It seems to have faulty door latches.

The passenger window keeps going up and down without the switch being used. This happens while driving and even when the car is parked and off in my driveway.

Engine cooling not working. Hoses probably defective. Fire risk.

A/C started to blow hot air. The auto repair stated its the evaporator need replace, its a costly job and very common.

Evaporator core was installed incorrectly on the air conditioner

When I have my front right window down about three inches and accelerate, I get car exhaust into cabin. I later found out that the exhaust moves from the exhaust pipe of the moving car into the car trunk and then into the cabin of my car. I first noticed this days after I purchased the car but the dealer could not duplicate it and said it was probably a new car smell. I had it checked again three months after purchase but, again, mechanic had same outcome. I finally got fed up with the smell and asked again 18 months after purchase. Ford spent weeks examining it and had a Ford technician also examine the car. Ford found the smell this time and said another Mustang like mine also had the same smell. Ford claimed the smell was normal for this type of Mustang. I had an expert test the car several hours one afternoon (see part of report attached). He found that carbon monoxide was much higher in the trunk than in the cabin. He found levels as high as 411 ppm in the trunk and 14 ppm in the cabin. He concluded that exhaust moved from exhaust pipe to car trunk to car cabin.

Purchased this car brand new & the air conditioning quit working the first summer I owned it. While under warranty, took car to family Ford and they put freon in it but it leaked out, they replaced the compressor, problem persisted. Next found that the compressor was improperly installed & that was repaired. Now warranty is expired & dealer diagnosed the problem as the compressor & told me to pay out of pocket for the repairs. Car has 16,000 miles, garage kept, and has never had working ac.

My car's A/C broke down while driving early July of this year. It took four visits to the dealership to identify that the evaporator core was the issue. Before this, the schrader valves, condenser and associated parts were replaced.

Just picked my car up from dealership, due to a battery issue that I previously posted about, and my driver side vents are blowing warm air. I googled this issue and just like the battery issue I reported, this is not an isolated incident with the 2016 Ford Mustang. I will now have to bring my car back to the dealership and hope that they can get around to diagnosing it in the next couple of days. I can't understand why there have not been recalls regarding these issues, when Ford is obviously selling defective products. My car has 30,400 miles tomorrow will make the 5th time it has been in the shop over the past year. Investigation into these cars are obviously warranted.

Air conditioning stopped working. Dealer service tech found air conditioner evaporator is leaking. Vehicle mileage 22968. Service tech indicated that this is the second occurrence recently and he is scheduled to replace an evaporator on another Mustang tomorrow. Repair involves removal of the dashboard and cost of the part alone is over $1100. Similar issue listed many times here and many more times on discussion boards and forums.
