GarageCalc What the data says
Electrical system accounts for about 36% of this year's Ford Mustang Mach E complaints. This is a share of submitted complaints, not the percentage of vehicles affected. A component category alone cannot establish a defect or its cause.
The 2021 model year contributes 21 complaints (29%). Model-year totals are not adjusted for vehicles on the road, mileage or age. Check the specific vehicle's recall record and complaint narratives before drawing a reliability conclusion.
Complaints are down year over year, 97 to 72 (-26%), while all complaints rose about 2%. This compares reports received in the same date window, not failures per vehicle. Changes in fleet size, vehicle age, reporting behavior and model naming can affect the trend. Without an exposure denominator, a rise cannot establish a higher failure rate.
How to read this
Raw complaint totals track how many Ford Mustang Mach Es are on the road as much as they track quality, so a high count on a best-seller is partly a volume story. Complaints are also self-reported: they capture what owners chose to file, not a controlled survey. Use these numbers to know where to look during a pre-purchase inspection and which recalls to check, not as a verdict on their own.
