2019 Mustang GT Premium Window Controller Thump
I took delivery of a 2019 GT Premium in early July, my second Mustang. So far, so good, although I will confess that I had a great deal of trepidation about purchasing a new Mustang given the myriad of problems I had with my 2012 V-6 convertible.
This afternoon, I lowered the driver's window and as it ran to the bottom it stopped with a relatively noticeable thump. I raised the window and lowered it a second time and experienced the same noise. I then did the same for the passenger window and it ran down smoothly and silently. On the third or fourth run on the driver's window it functioned fine.
I had this problem all throughout the 8 years I owned my 2012 V-6. I complained about the loud clunk when the window hit bottom very early on, while the car was still under warranty. Of course, the dealer responded they could not duplicate the problem. Occasionally, I had the same issue with the passenger window. Shortly before my extended warranty expired I brought my V-6 in and showed the dealer that the passenger window rested approximately 1/4 inch above the door while the passenger window was flush with the door -- clearly, one of the windows was not functioning correctly. The dealer replaced the driver's window controller, but the problem persisted intermittently over the time that I owned the car.
Given the massive amount of work on my 2012 V-6 (lower control arms, bushings, lower control arms again, rear anti-sway bar, front anti-sway bar, rear anti-sway bar again, window controller, water pump, automatic transmission cooler, and a convertible roof bracket replacement all within 74,000 miles) you can understand my wariness about purchasing another Mustang.
The loud clunk on my 2012 V-6 was very annoying. Now, I've experienced a similar issue with my 2019 GT Premium. Is this a problem others have experienced? Is it simply endemic to Ford window controllers? Does this portend potential issues in the future? Once again, I have purchased an extended warranty that takes me to 6 years/60,000 miles so I have time.
