Good morning friends!

I had a very weird issue occur yesterday while waiting for my wife at the store. I parked turned off the engine, (forgot that I l left the key in the on position), the decided to power fold the mirrors bc parking was tight at Costco. While waiting in the car for my wife, I was on the phone with a friend, maybe waited for my wife a total of about 20-25 mins. I saw a better parking space that I wanted and I went to start the car and it was a slow start, hmmm wtf....and I stop cranking and tried to understand why the batteries (I have dual odyssey batts), would be low on power. Then I immediately cranked it again, still slow cranking and the engine turned over, WHEW.

So I left the car running while continuing to wait for my wife. Then we were on our way home. I thought maybe the batts were low bc we don't drive often anymore bc of pandemic, and its been cold outside. But the car started up just fine to go to Costco. So we get home and I'm still trying to understand the root cause, the batteries are only 5 years old, from time to time I will trickle charge them.

So I went about my business and had to blow leaves out of my driveway, as I was picking up the power cord which was near the passenger's side mirror, I bent over and grabbed the cord as I stood up, I heard a buzzing noise, very faint, I'm surprised I heard it with my ear protection on. The buzzing was coming from the side view mirror. It was as if either the mirror was still trying to power fold/unfold itself, and when I pushed on the mirror portion to manually adjust it, the mirror would adjust itself back to the original position. Car has been off for at least 5-10 mins at this point, key was not in the ignition, and the driver's door was opened after I took the key out of the ignition.

So I kind of panicked, lol. I was thinking should I disconnect the batteries? So I hit the power fold switch to fold the mirrors in, and the buzzing stopped. I then folded them in and out exercising them a few times and it hasn't acted up since. This happened yesterday afternoon.

I was just curious if anyone has had this issue. If my wife was alone and she had power folded the mirrors at the store, she wouldve probably needed to get a jump. So this issue has me on edge a bit. I'm thinking the mirror when I folded them in at the store just never got the signal or sent the signal to say "hey I've reached my folded in position, so kill power to me", which is what caused my slow start at the store.

I'm hoping this was just a one off issue, lol. But this car has had many one off issues. Its a 2007 Tahoe LTZ, with about ~295K miles on it.

Thanks in advance!

 

Salt got into my '11 mirrors causing them to bind up. I'd pop the covers off and lube them. Relay for them could be sticking also.
