Ford uses to issue Technical Service Bulletins whenever a problem or defect is found at a car. The main aim of this tipe of warnings is to correct the problem, but this time the car maker has released the latest TSB for a different problem.
Ford said it “addresses the fact that“ some 2011 F-150 and 2011-2012 Mustangs equipped with the 5.0L engine may have unauthorized modifications to the power train hardware, which may result in exceeding component limits.Such modifications could cause damage to the powertrain and/or void the factory powertrain warranty. Attempting to increase the engine output via recalibrating the PCM may result in poor drivability or component failures.
A Ford representative stated:“customization is a big part of the Mustang ownership experience. This [TSB] is designed to alert people to the possible damage and warranty ‘voiding’ one can incur if they modify their vehicles beyond factory specifications.”
The owners of 2011+Mustangs will be affected because Ford can not automatically void your warranty due to the aftermarket modifications. The fact has backup in the Magnuson-Moss Warranty Act of 1975 which states that it must be proven that an aftermarket part directly caused a failure to original equipment parts to void a warranty.
MustangDaily.com affirms that increasing horsepower and torque can be done safely, although it can be done in a harmful way that will damage the engine internal components. Aftermarket products designed and produced correctly will increase your Mustang’s performance and will not void your warranty.
