The 2021FORDMUSTANG carries 59 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 6 crashes, 0 fires, 4 injuries, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall Not Rated/5 rating, with Not Rated/5 front crash, Not Rated/5 side crash, and 5/5 rollover scores derived from standardized barrier and dynamic tests.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2021 MUSTANG is power train with 8 filings, followed by engine (7) and fuel system, gasoline (7). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 6 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle, the full NHTSA campaign numbers are listed below.
NHTSA currently has 3 investigation files overlapping the 2021 MUSTANG, and 1 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page, a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

I RECENTLY PURCHASED THIS CAR. THE REAR BACK-UP CAMERA WAS IN A FLIP FLOPPED STATE. MEANING, WHAT WAS DISPLAYED ON THE CABIN SCREEN ON THE LEFT, WAS ACTUALLY ON THE RIGHT PLUS THE GUIDING LINES ON THE SCREEN WERE MISSING. I PURCHASED AND INSTALLED A NEW CAMERA FROM FORD. THIS FIXED THE FLIP FLOPPED IMMAGE , BUT, NOT THE MISSING LINES ON THE SCREEN. SECURING THE WIRES I NOTICED THE WIRING HARNESS AT THE BEND AT THE DECK AND LID WAS FULLY EXPOSED TO BEING FRAYED BY THE METAL DECK LID. I DID NOT SEE ANY COPPER WIRE SHOWING. BUT, I WONDER HOW LONG IT WILL TAKE TO FRAY TO RAW WIRE? I ALSO OWN A 2015 MUSTANG GT THAT WAS RECALLED FOR THE EXACT SAME CONDITION. THAT WIRING HARNESS WAS REPLACED BY MY LOCAL FORD DEALERSHIP IN 2024.

Rear camara is inconsistent but lately works 25% of the time.
While entering an on-ramp and just before merging onto the freeway the vehicle failed to accelerate and I lost complete power from the engine. The vehicle was still powered on, but produced no combustion from the engine. The check engine light illuminated and a message appeared on the dash stating to shift the vehicle into neutral. I pulled off on the shoulder and shifted the vehicle into park. I shut the vehicle off and started it back up. After doing so I had full power once again. This is the sixth time this has happened.

My 2021 Ford Mustang EcoBoost is currently experiencing an ongoing issue with the EVAP purge valve, a critical emissions component. The vehicle suffers from stuttering, rough idle, and a check engine light, especially immediately after refueling, where the engine has stalled multiple timesâposing a serious safety risk during traffic re-entry and acceleration.The purge valve has not been replaced, and the issue remains unresolved. I contacted Ford Customer Relations and three separate Ford dealerships, all of which refused to service the vehicle under warranty, despite the fact that it is still covered under the federal emissions warranty (8 years/80,000 miles) and the powertrain warranty.This refusal contradicts federal warranty guidelines, as the purge valve is clearly part of the evaporative emissions control system. The failure disrupts vapor flow and fuel trim stability, leading to erratic engine behavior and emissions system malfunction.I previously owned another Ford Mustang Ec

While driving my 10R80 automatic transmission shifted into neutral even though the shifter was positioned in drive.

I then started the vehicle back up and began driving. The transmission continuously shifted rough while driving my destination.
