Lots of condensation on the inside of windshield

I live in the north east, so some is expected, but never have I had this amount of water on the inside of my windshield without having left windows open.... and this happens a lot.

 

There’s a leak!

 

You have a leak ... or a couple homeless guys are sleeping in there every night

 

Heater core leak maybe??

 

Ugh, I had less issues with my Hyundai Elantra and that car was a trash can on wheels

 

Is that the original windshield?

 

Yes, and the truck is only a year old.

 

Well your maintenance light is on and it appears you have a bad seal. Time to visit service while you are still under warranty.

 

Maintenance light was on just for routine 5k maintenance.. but it is there now and I asked them to look at it... but I bet they say nothing is wrong, this dealership never finds anything.

 

Yep usually a sign of excessive moisture in cab from a possible water leak..

 

Mine has been like that since new so I carry one of these

 

Haha, not a good solution, but a temporary fix.

 

You know you can reset the reminder easily, especially when you decide to skip an interval.

Get the issue into your records then file a complaint with Toyota Corp.

 

Think I should file a complaint to corporate for this issue? I also have a weird vibrating noise under the hood at low RPM's that almost sounds like a muffler leak and they can't seem to fix it.

 

In my case the moisture seems to just “show up” so I assume it happens in high humidity. A little off topic but I wonder if the piston rings are wiping down the cylinder bores and recirculating that same moisture into the oil and causing that foaming some people are experiencing but I could be wrong

 

Hello.
A leak (as stated)... My father in law had this condition (not a taco but...) where his windows had a lot of condensation on the inside, same as your issue. It turns out his sunroof drain passages were clogged with debris and the water was finding it's way inside his vehicle. Possibility?... Good luck.

If you have no confidence in your normal dealer service department, I would try another dealer if there is one reasonably close.

If you aren’t getting these issues solved, you should escalate to corp.

 

Mine was the 3rd brake light. I had a few mornings where the condensation was so bad it was dripping. Only on the windshield though. A month or two later and the back seat was wet. Since the brake light was replaced, I haven’t seen any condensation. That’s been 6 months.

 

Do your windows typically fog up while driving? Make sure fresh air is on and perhaps use your AC is get rid of the moisture. In any case, need to get that fixed ASAP before mold/mildew sets in.

 

As stated above, check your 3rd brake light for leaks. It is a known issue.
