Strange steering pull when accelerating

[1MeanZ]

As was stated above, check your rear wheel bearings first. This happened to me, was rear wheel bearing.

Could also be a bad motor mount.

Long time lurker and very occasional poster here.... I have a 2021 GT/PP with no mods and OEM Pzero tires. Over the past couple of days the car has developed a significant pull to the left when accelerating - both from a slow roll and highway speeds. Also, it feels like the back end is shifting slightly to the right when this happens.

It has never done this before, so it obviously seems very strange. Tire pressures are ok and i dont see anything visable during a very basic look around.

Any thoughts/ideas on when might be going on?

Thanks

If your car is stock, the subframe can move throwing everything out of alignment. This is why there are so many goodies we can put on our cars. Like centering kit, bush support kit, brace's.

Welp...turns out that the left rear tire had less than 10 lbs of pressure, and the TPMS didn't pick it up. I went to pull the wheel off to check the hub and noticed the tire looked low. Filled it back up and the pulling problem is now gone. Time to get rid of the P Zeros now...

Thanks for all the help!

the TPMS didn't pick it up

Happy to read it was an easy fix.

The TPMS batteries last for like five years or so. If you haven't changed them before, I'd install new stems and sensors when replacing the tires. I'm using a set from Ford Performance with aftermarket rims; they sync'd by themselves almost immediately and have been working very well.

I noticed your car is a 2015. The TPMS batteries last for like five years or so. When replacing the tires, I'd install new stems and sensors. I'm using a set from Ford Performance with aftermarket rims; they sync'd by themselves almost immediately and have been working very well.

I need to update my profile - I have a 2021 now. I also have a problem with the TPMS and get a TPMS fault message/light daily. I tried relearning all 4 wheels and that didnt work, so maybe it is the batteries in one of them as you suggest.

I thought about the warranty, but even if in-effect, they'd pro-rate it out.

I haven't used them myself, but they do make scanners to detect which rims are talking. As part of an overall purchase, a shop might locate which three are working, for free.

At three years, maybe more, might be a good idea just to go for the throat and replace all four now.

One thing I can recommend not doing: using any electronic item off eBay. You might have noticed before, but we've had a few threads of value TPMS sensors, almost all of which were causing problems for the owners..

But ya, glad you got things sorted.

My '12 Edge had an odd TPMS issue. For short drives it was fine but at about 100 miles of driving it would set off the TPMS light. I'd check tire pressure but all were good. That era Edge didn't display tire pressure on the dash so I couldn't narrow it down to an individual tire. Anyway, Costco installed 4 new sensors (not Ford sensors) for about $120. No problems since.
