So anyone noticed a build up of condensation on the inside of the windshield? This has been stated on other forums as well. Never had a car do this, usually in the eve after car has ran. Come back and all windows on the interior side are fogged up

Cheers

Have noticed several times. Just adding it to the list.

Acura hasn't issued a service bulletin yet, but after they watch this video I am sure they'll consider it...

I've not experienced this to date.


That's would indicate a pretty high moisture rate inside the car, I would imagine. I have noticed that some people choose to turn off their AC in the Winter, resulting in humid, warm air being introduced into the cabin. This can lead to condensation and fog up when returning to a vehicle.


If not already doing it, make sure your AC is on while heating the car to ensure that warm, dry air is entering the cabin. This is probably the best method of controlling the issue, since you can't often control the relative humidity and dew point. Any time the temperature inside the car (like after you've driven it) is warmer than the outside temperature and you fall below the dew point inside the car, the water will condense on the windshield. Since you can't easily control temperature differences between the parked car and the outside, it's best to try to remove the water vapor from the cabin air to minimize the effect. You might also get more benefit from the vent setting being on recirculate as well. Since this ensures that warm, dry air remains in the car once the moisture has been removed by the AC system.

 

Pressing the Recirculation button might also produce the condensation, or if the vent is stuck in the closed position (a service call).

 

I live in Iowa and use the remote start often. When it's cold and humid (often) and the car was remotely started, the rear glass will fog completely within two minutes of starting to drive.


Another issue I have with the climate system is setting a comfortable cabin temperature and then getting cold air coming off the windshield and hitting me in the face. This is most noticeable, distracting and annoying when driving on the highway.


I keep remembering the salesmen at three different dealers all telling me that the climate control system on the TLX is the most advanced system available....and I keep thinking it's the most complex and annoying system I've ever seen. Pretty unbelievable that any new car can't be set on "auto" and have the seats come on, have the cabin stay at the set temperature and expect it to keep the windows clear. I'm not looking forward to seeing what it will and won't do next summer when it's hot.

 

OP states the windows fogs up after parking his car. Not while driving? Also says that it hasn't happen to any of his previous cars.

So the problem might just be the car.

 

FWIW, I leave my settings on "Auto" and have never experienced any fogging. i drive in a wide range of weather extremes.

 

The car clearly has hvac issues. My last three cars had auto climate control (accord EXL, golf GTI, TSX) and they all worked perfectly. As they do in all the Hondas I sell. In the TLX I am forever having to fiddle with it. No mean task as its touch screen interface is stupid. That and the heated seats. Everything else is lovely. I just do not believe it was properly winter tested. I really don't.

 

Well said. Blunt, but accurate. You are exactly right that the HVAC system has to be constantly "fiddled with" to keep the car fog free and comfortable. The "auto" setting on this car is a cruel joke or an act of
corporate sabatoge. Had anyone informed me about the climate system in this car before I bought it I would have thought they were exaggerating and that there is no way it could be that bad. My bad for not waiting for some objective reviews and buying a first model year from a company that has plagued itself with new model problems in the past.

 

This is strange, but I am not having any of the issues and it handles the cold conditions in a similar way to my 3G TL:
- leave a semi warmed underground parking garage into the cold of -10C, no issues or adjustment of controls
- parked outside for a few hours in -10C and with or without remote start just get in and drive, no issues or adjustment of controls

However, I usually use waterless products to wash my car so there is no potential for water seeping into the inside or residual accumulation in the air vents.

 

The only issue I've seen is the back glass being completely fogged up the other morning after using remote start. I've no idea where that condensation came from.. though we've had a lot of drizzling rain the past few days.

 

I think I started the post you're referring to on the other website. The car was sitting in a parking lot for about 2 hours before I got in. All windows/sunroof were closed and I didn't have any open beverages in the car. Prior to parking it I didn't run the ac or defroster. It was very wet.. I mean a couple of soaked paper towels wet. But it only happened that one time and I haven't seen it happen again.

 

I would urge anyone with this problem to check the carpet under the mats. I've had a both of my TSX's end up with wet carpet in the all the foot wells due to clogged sunroof drains. This may be the source of the moisture inside the car.
