A couple times in the last month or two, my park assist comes on for apparently no reason. I am stopped at a light, with no one in front of me, and it starts beeping rapidly as if someone were almost touching the front of the car.

Last night I noticed it again, this time it was snowing somewhat. Anyone else have this problem?

 

Also, this is a 2010 GX bought in May. Around 5000 miles. I don't know if it's related or not but my brakes have started to squeak. Is that normal already?

 

Yes, I do have the same issue, when it snows a get it more frequently. Sometimes on the highway it has come up, once or twice.

 

Yes, it happens because the sensors are a bit too sensitive. There was a time when the alarm went off non-stop, and sure enough the whole front bumper was covered with snow. As with the squeaky brakes, it just means they're dirty.

 

how many miles?
squeaky brakes could be worn pads (i doubt this early), or not enough grease in shims and along caliper where it meets pad.

 

I don't have the squeaky brakes, but have had the park assist come on when it's snowing. It also happens on my LS 460. You can disable it if it bothers you...

 

The trick is to keep the sensors clear of snow- I know that is sometimes a bit tricky in a snowstorm. I have an RX with the sensors and I pass the snow brush over the sensors prior to driving off and then there is no more issues unless there is a heavy build up while driving!

just turn the sensors off during bad weather. It takes 2 sec and no beeping problem

 

That's what I do and put that in an earlier post...

 

i usually dont ask such a dumb question, but i cant find answer on lexus website and i could of sworn that the side view mirrors point down when going in reverse. My mirrors arent pointing down in reverse, are they not supposed to this? I just replaced the blind spot mirrors and noticed this today

 

Not a dumb questioned I figured it out by accident. You have to choose either left or right on the mirror adjust button for some reason it can't be in the middle then mirrors will point down in reverse

 

ah thank you, i will try that. the button is in the middle!

 

Silly question for the team that popped into my head after I jumped into my buddy's LS460 the other day . . . His IPA is a stand-alone button on the dash that he has constantly engaged and a little green light is lit on the button (good); for the GX (as you know), when the IPA is on, we have an indicator in the instrument cluster (bad).

The question that occurred to me, is how many of you (like my buddy), leaves the IPA on all the time?

At first, I didn't like the idea because I didn't like the P" indicator constantly on (distracting), but since it is green like the "ECO" indicator, I guess it doesn't really bug me that much. On my past car, when I shifted to reverse, the sensors turned on automatically (which I liked) and the reality is, since I have to turn the IPA on manually now in the GX, I never turn it on. Haven't really needed anyway . . .

Should I just leave it on all the time? What do you do? Thanks! KH

 

I leave it on all the time except when the sensors are covered in snow, then I turn it off. The little green light doesn't bother me.

 

leave it on all the time. the one time you need it you will back into something and then cry about it. happened to someone on the 4runner site.
