Auto Park Brake vs Manual
Any opinion on this - I like the auto brake feature - but does it cause ‘wear and tear’ or do most just use the manual parking brake? - Just curious

It's electronic, so whether you leave it on auto or set it manually, it's all the same... unless you're one of those thousands of drivers out there who think shifting their transmission to P is all they need to do when parked... smh...

Having said that, to the OP's question, if you only engage it while stopped, the wear and tear on the brake pad/rotor hat will be very minimal. The electric actuation mechanism will cycle but I don't think you will wear it out before needing other major maintenance.

Thousands? How about Billions! I only use the parking brake on my stick cars. The rest I test periodically but I don't use regularly. Most, as in 99.99% of people with automatics don't have a clue how to engage their parking brake in newer cars that aren't a hand lever or a foot pedal. I doubt my wife knows where or what the button does in the center of her HR-V console.

I taught both my kids why the parking brake exists and that leaving the trans in P without the brake only puts stress on the transmission, especially when you park on a driveway with an incline. I can't say for sure the added stress on the transmission will cause premature failure, but the logic (in my head at least) tells me that when engaged, the parking brake prevents the car from moving, when left off, the weight of the car rests on the transmission components.

Aw man... c'mon... do you really not use the parking brake on your GS?

Yes, that CAN happen but I'd bet dollars to donuts that was the result of a park slam, the exact opposite of a neutral drop. You can try to make it happen by locking the brakes (if possible on new cars) and shoving it in park and simultaneously releasing the brakes. Preferably at a speed greater than 20 MPH. It will likely flat-spot the tires if it doesn't snap the parking pall or rip the transmission case.
If this were a REAL problem, there would be more PSAs about it than wearing a seat belt and child safety seats combined. Especially in San Fran where a car could really build up some speed and do some damage.

I don't have it but mine is garage-kept. Others have reported that sound on their 350s and it does occur on the17 Civic and 02 Sequoia in the family, especially when kept outdoors. Normal.

108k miles on my GS auto park has always been enabled, never an issue. I agree with Knucklebus, I don't think it will ever truly wear out because it's only engaged when the car is not moving. If you use the brake hold feature all the time then you'll probably have to change the auto park brake shoe eventually.
