I think I was built 18/March/2023
Delivered & picked up 31/March/2023

If you asked me yes or do, do I have shuddering brakes... I would say yes.

I rarely notice it. A lot of country roads and working 3x12hr shifts I'm driving to work before everyone else & driving home after everyone else. I never drive in stop/go traffic. Sometimes slowly breaking to a red light or stop the brakes are not smooth... they're dut dut dut dut dut, I don't know how to describe it... grabby.

I noticed it really bad only one time. I had to tow a disabled vehicle (transmission went out) off the road into a parking lot & in tow mode I had one moment the brakes were insanely difficult to operate. It felt very unsafe and dangerous trying to go slow and be careful but when I used the brakes the brakes were slamming on//off and jerked the Maverick. Not a smooth operation.

separate issue from the brakes "locking up" at low speeds.

new TSB speaking to the "shuddering" when the power moves from either electric to gas or vice versa.

There is also a "shuddering" that happens in hybrids when you accelerate strongly and the entire vehicle shakes.

I am not sure if it's different to the 'grabby brakes'. The initial post says: "may exhibit a shudder or vibration when the vehicle is braking at 15 mph (24 km/h) or below"

Sorry. I didn't add anything. I think it's stupid to repost your (or anyone's) entire block of text to know it's in reply to you. @FriscoTXJoe would work better. Nobody is going to reread the post again and nobody needs the entire post on their screen twice. It looks dumb when every reply in a thread contains a massive quote.

It's just personal netiquette of mine. Only quote the relevant parts or the parts I am referring to/replying to. Like quoting a source in a university paper... You only quote the important part not an entire page/paragraph of the source.
