Filed Feb 1, 2026 · Engine, Fuel system · CA

At about 75k miles my mustang started misfiring at about 2,500 rpm’s and higher. Turns out it was a blown head gasket. This engine model is prone to what happened to it. Ford should have a recall for these engine and a solution as they’re ticking time bombs. I wish I could drive with the peace of mind of not worrying about it. I couldn’t drive my car for months because of the warranty not even wanting to cover it. The warranty from the used car dealership. Got unlucky.

2016 Ford Mustang V6 This is EXTREMELY concerning as it's a SAFETY issue losing power features while the vehicle is in motion. While driving the car provides an error message with a wrench sign/icon stating the transmission is not in Park, then it proceeds to shut down the car leaving us without power steering. The car need stopped, move the transmission to Park, and start the engine. Doing this clears the warning and you are able to drive the car without any problem.

The new purge valve is faulty in my car. It has been replaced once in 2017, and another time in 2022 (possibly 2021), due to a total engine rebuild under powertrain warranty. This valve is a known common issue on online forums. For the model cars 2018 and 2019, this is an open recall. I strongly believe this should be investigated. In the past, this faulty valve caused my car to stall and die on a busy road. Both Ford customer service and the dealer have given me conflicting information whether or not this part is covered under emissions warranty, causing a headache. The dealer stated that if given a sequence of codes, the dealer has been instructed by Ford to replace the part for free. This indicates that Ford is aware of the common hazard that the faulty purge valve is causing. Considering this part is less than 2 years old, it should at least be covered by the 2 year emissions warranty. However, I believe others, like me, have suffered the nuisance and safety risk of this faulty part, and have paid unnecessary expenses due to Ford's negligence to address this known issue.

Periodically when shifting from 2nd to 3rd gear, with manual transmission, I am unable to engage 3rd gear, like I am locked out of 3rd gear. My safety (and vehicles around me) is at risk because I am unable to continue accelerating and have to either go back to 2nd gear or into 4th gear. This problem has not been addressed at service center as it is intermittent. I have had this happen dozens of times. There is no warning when this happens.

In my 2016 ford mustang eco-boost, I started my vehicle and noticed the air was not as cool as it was in the past. I did not pay much attention as I did not have far to drive. The next time I started the vehicle the air conditioning had started to blow warm air, after awhile I noticed a white film on the interior or the cabin. I looked up several forums on what this issue could be and there are multiple mustang owners of this year that are experiencing the same thing and it seems to be the evaporator core. So I took it to a local mechanic and they informed me it would cost $1900 to fix the system due to the labor of taking out the dash. I have been a ford owner all my life and this is ridiculous.
