- 2019 Regal GS
I just got a call back from Buick and I got an appt. to get this looked at and hopefully they will find and can resolve the problem on Monday.I have a 2019 regal AWD bought in January 2020, and im at almost 22K KM and started having vibrations, it only happens on the 7th gear between 50-70 KM/H, when im on the others gears at this speed there's no vibrations, i just changed from my summer to my winter tires/mags this weekend and still the same outcome with two different types and brands of tires/mags and since the winter tires/mags were previously installed last january so i think it's safe to assume it's not a problem with the tires/wheels, now im waiting for a call back from service to confirm an appointment to get this resolved ASAP.
What's going through your head as far as possible causes?Well, it looks like I'm renewing my membership in the Rear Diff. Club for '21. Noticed last month mine was seeping again, had it replaced last Aug. Have appt. next week to take it in again. The first replacement lasted about 3500 miles. Now have 12K on the car.
Well, there are only four choices, bad seal, bad installation, bad machining on the diff. or something from the first replacement needs retorquing. Still under warranty so not too worried. I'll post update after I get the car back. Take it in Tuesday, Jan. 12th.What's going through your head as far as possible causes?
I have to imagine it's only a bad seal, a poor installation, or something else forward of the diff causing the issue to reoccur. Having two diffs go out/leak in such a short service life is odd.
