My wife recently took her new 2017 mustang in for its 1500KM "piece of mind service".
Picked up the car and immediately noticed it wasn't driving the same - doesn't seem to be accelerating as smoothly, running at about 20 l/100km up from before the service, she also says the exhaust smells more noxious...... (haven't had a chance to check yet)
She has had it back to dealer but they recon nothing has changed ... going back in tomorrow.
Any thoughts ? (Can't help wondering if they accidently changed mapping.....)
Cheers
