Is anyone experiencing any heating problems with their TLX

 

Got down to 24 degrees here last night, no problems at all! Heater heated up quickly and kept me warm without issue!

 

+1, no problems at 40+ during the day today. Quick and quiet.

 

I will have to wait till winter gets here. It's 82F outside today at this moment. May drop into upper 70s tonight but no heater weather yet.

 

The heat on the TLX seems to start coming out faster than on my 3G TL. I also discovered that the heated windshield (Canadian Elite model) is automatically activated when the outside temperature is around 3-4C and does not appear to turn off automatically. It can be turned off by pressing the switch.

 

The heat comes out fine until it hits the set temperature then it seemed to start blowing out cold air.Even with the temperature set at 28 its still cool in my car.The car has been at acura twice now and they're telling me that is normal for the TLX."no heat" I have owned a 2007 TL Type S & a 2010 TL a spec and they have never had a problem with them. I would set it at 24 and it was comfortable.

 

Try this test and report your findings. Set the system to auto mode, and make note of the exterior temperature and the heating/cooling temperature setting. When the warm air stops coming out what is the outside temperature? Also, manually turn off the a/c, and see if you feel any difference in the temperature of the air flow.

 

I have this EXACT same problem. I keep it on "automatic" with 72F temperature setting. Over the past week, it has been very cold outside. The car will warm up from the floor vents but then cool air will eventually start blowing from the windshield area even with an outside air temperature of 20-35F. As an experiment, I turned the temperature setting as high as it would go (80+F) and warm air did finally start blowing out of the windshield area. It almost seems like the interior thermostat is not working properly and so I have made yet another appointment for TLX service later this week.

 

My car is still at acura I will report there findings when I get it back..This is the second time I have had it in for the same problem a total of 5 days so far.

 

Think I understand Air Con system is set to Auto Mode and believe your problem is due to the way the system thermostat is set up, unless there is a controller or gate opening and closing issue.

Try running the Air Con system in Manual Mode and see if there is any difference. Heat settings will still work as normal even in zero degree temperatures. Personally I have not used Auto Mode for over 20 years, don't like the way they cycle fan speeds and air movement.

 

I have tried with the air conditioning on auto and off it doesn't make a difference. Even with the climate control in manual mode it still doesn't keep the warm.

 

Same here. Mine is going back in for service on Thursday. I hope they can get to the bottom of it.

 

Now that the air has gotten cooler here, I notice the same thing.... Set at Auto 72, car starts to warm up inside but doesn't get to a comfortable 72... increased it to 80 and better, but that should not be the setting... a bit worse on highway as cool air enters, but it seems that the thermostat is not accurate.. Previous TLs, TSXs all comfortable at 70 to 72 (on hiway).

Any reports of fix? It's going to get colder here.

Thanks

 

Same heating inconsitancy with mine, too.

 

acura told me it was normal operation of the TLX I'm kind of hoping somebody else can find the problem but I agree I think its the thermostat

 

I have been wondering about this - I have had a number of cars with fully auto climate control and never a problem. Nor on all the Hondas I test drive at work. But with the very cold temps here the last few weeks, I feel my feet getting cold after a while and wonder why. Been thinking it is just snow melting and soaking through my shoes...so I have been overriding auto recently to crank up the floor heat. Maybe something is amiss...and it's not just me.

 

^^ You aren't the first guy experiencing "cold feet" (lmao)

I hear ya though, that one thing I hate about most cars....it seems that the foot ventilation is never as good as the cabin or windshield vents. When my feet are cold, my entire body is cold.

 

^^ Based on where you live, you should know that a good shot of alcohol get the circulation moving (written as I am sipping one). Heated seats also help.

 

Despite the dealer keeping my car overnight and putting several miles on it to further evaluate my concerns with the heating system, they claim that nothing is wrong. Nevertheless, I continue to have the exact same problem with a very noticeable discrepancy between the set and actual temperature. I let a friend borrow the car for the day and he even noticed it without me saying anything. I don't know what else to do other then bring it to another (further away) dealer although this is quite an inconvenience and should not be necessary. I suppose I could call back Client Relations although they have not been helpful at all with my previous issues with this vehicle. Hopefully, if enough of us call and register our complaints, Acura will finally look into it and address the problem.

 

Here's my 2 day comparison... Yesterday, I drove home in dry, but cool weather (32 degrees) and while in Auto, 72 degrees, on a hiway, the car warmed up, the defrost fan went off and i was most comfortable.. even lowered the set point to 71 degrees. Today in that driving, windy Noreaster rain, though warmer outside (42 degrees), the car warmed up inside a bit, the defroster fan stayed on while on a hiway, but the car felt much cooler even with the setting raised to 76. Tried turning the defroster fan off for a bit but no real change.. Latest guess it's that Auto and the temperature gauge on the dashboard that is creating these issues.

How does that auto work, anyway?

 

Here is how the system should work (my car and previous TL).

Set the temperature and press Auto. The system will take over and turn on the heating or cooling as required, adjust the fan speed as required, and direct the air flow to the appropriate vents. As the temperature in the vehicle reaches the set temperature the fan speed will be reduced and heating or cooling adjusted, and will continue to make minor adjustments as required.

Pressing any of the other controls buttons (Fan Speed, Vent Mode, Windshield Defroster, A/C, or Recirculation) overrides the Auto setting. Pressing Auto again will put the system back into automatic mode. The Windshield Defroster is only automatically activated via remote start.

If the engine was turned off while in automatic mode, it will resume automatic mode when the car is restarted.

 

Thanks Quandry... Exactly what I do, though it seems to be effective some of the time and not others... tonite coming home after the stormy day with outside temp of about 40 degrees, car felt warm.. this AM in the storm at about the same outside temp, with a setting of 76, car felt cool... I've had several Acuras and always did as you said with no complaints.. I'm still experimenting when it is cool and when it is comfortable. But thanks!

 

Mine behaves oddly sometimes, too! First, 70 or 72 in this car feels like 66 or 68 in my past cars. Sometimes (can't pinpoint the exact cold conditions) the defroster will run unprompted. OK it's Auto so it must know what it's doing, right? But it's running nearly full fan and won't seem to back off even after the engine is full temp. So I went manual and switch the airflow to the floor but with the fan still on Auto, thinking it needed to blow at high speed, air was still pushing out of the defrost vent (only louder because the vent was "closed") and the air was not warm! I then set fan to manual, then everything back to Auto and it behaved sensibly for the rest of the drive. Even if there's nothing ""wrong"" with this car, it's so quirky I don't like it.

 

With my car I will hardly hear the fan under these conditions:
- car has been sitting for 4 hours with outside temperature of 2C
- inside temperature set at 24C
- fan and controls set at Auto
Shortly after starting when the engine warms up, it blows warm to the footwells, and none through the side vents. I have not noticed any cool air to the windshield defrost vent, but have not specifically checked.

Assuming that your situation is repeatable, particularly with high fan speed and air from the defrost vent even if the system is set to Auto, then that is not normal. Take in for repair.

 

My TLX is back in shop today for replacement of a trim piece that was damaged during replacement of the defective headliner. At a previous visit, they assured me that my heating system was working fine but this is obviously not the case. This morning, it was 36 degrees while driving to the dealer, and COOL air was blowing from the windshield vents! I had been driving for a good 20-25 minutes and so engine was warm. The car was set to 72 degrees (which feels more like 65 degrees in my previous two Acura TSX vehicles) and AUTO light was on as usual. I left the car running and had the service advisor come in and take note of it so my concern won't simply be dismissed as before. I'll update everyone when I pick it up tonight.

 

I picked up the car and the service advisor finally confirmed that there IS a problem with the heating system. They measured an 8 degree (cooler) difference in the car as compared to the set temperature on Automatic setting. They think it has to do with the software and spoke to Acura corporate about it but there is NO known fix at this time.

I don't know what happened to Acura quality but I have really lost confidence in the brand after taking delivery of this "Friday car," as they put it. I'm already looking forward to the day when I will be in a neutral equity situation and this car is only 3 months old.

 

My TLX Advance has the same issue. I think its endemic.

My I4 8DCT with Tech Package has the same exact problem too!

 

If you have not yet contacted Acura Client Relations, please do so as it may help to expedite a solution.

 

Fyi, I'm not really noticing anything on mine, I4 Tech, 71 feels about right and like my '13 Lexus at the same setting, but when it satisfies the temp it does switch to more upper vents, and that air feels somewhat cooler. I've had that on other cars, where they send the cooler air up at face level to keep you "refreshed", as the manual put it. It is odd that if the setting is off 8 degrees, it's not a simple fix. My home t-stat will let me do that!

Any chance the "GPS-linked" climate control could be doing something odd because of sun angles? Is it better in manual mode?
From the website:

When the climate control is in automatic mode and direct sunlight is warming one side of the cabin, the system will automatically adjust to compensate for the heat gain. The system will track the sun’s position to continually maintain the set zone temperatures, as needed.

The automatic climate control system uses the Acura Navigation System’s10 GPS receiver to continually track the vehicle’s position relative to the sun.
A solar sensor measures the sun’s intensity to determine its impact on interior temperature.

The GPS-link is completely automatic.

 

Interesting thought JIM256, but my issues were 1) on a cool, rainy day (no sun) and 20 I have the base 4cyl. model without GPS navigation.

Guess we'll keep watching this Forum for more examples and see how much of a problem emerges as the weather continues to cool. Hopefully, Acura will work on a fix, as it seems already that it is not an isolated issue.

 

Same for me. The issue occurs regardless of weather conditions. For example, while on a road trip through Kentucky, it was 17 degrees with cloudy/overcast skies. With the Auto feature activated and set to 74F, the car initially started to warm until cold air began blowing from the windshield vents. There is no reason for this when the outside air temperature is so cold. Even in manual mode, the car does not heat anywhere close to the set temperature. Hopefully, this is a priority item for Acura. I really expect better from a "luxury" brand. Heck, I have had rental Kia vehicles with better climate control.

 

Just a wild thought for those of you who are having troubles - are you driving in Econ mode?

 

Not I... I'm in Normal Mode

 

No, I use Normal mode almost exclusively. Good thought though!

 

WOW. I definitely have this issue! I noticed immediately that I had to set my TLX at a different temperature to keep the cabin warm than my TSX. TSX would be nice and cozy at 72 ... but even at 76 in the TLX, I've got the have the seat on and the air blowing out is definitely cool air. Have an appointment at the dealer on the 26th for another issue, and I'm definitely going to have this checked out. I also have a good rapport with Acura Client Relations so I'll make sure I dial them up so they are aware.

 

Thanks, Crown,

Keep us posted on any acknowledgements of a problem from the dealer and any "fixes" from Acura. It's too easy for some dealers to deny any problem, even as this forum identifies multiple occurrences. I still hope Acura realizes it and devises a fix.

I'm still sorting out what it does on it's own, what it is I want it to do differently and how do I get it to do what I want?


Most of my "problems" have been the learning curve on this car.
I find the climate and audio system controls are not intuitive at all and even after you learn to access and manipulate the menu's and options, they are still quirky at best.


I have the same cold air on the face issue several have described above. It's most noticeable during highway driving when the cabin warms to the set temperature then suddenly you feel a draft of 25 degree outside air blowing into your face from windshield defrost vents...that's very annoying.


Another issue I'm trying to sort out is with what the auto climate system does or can be made to do when I use the remote start? When I get in the car after remote start, it seems that everything is blowing full blast fresh air, then when I push the start button it resumes Auto setting. 30 seconds later when driving away all the moisture from the fresh air fogs up the rear window. Plus, I haven't found a way to have my seat heater come on automatically when I use the remote start.


Any solutions would be greatly appreciated. Thanks

 

All models do not have the same controls and it is possible that some operate differently. It would be helpful if you specify your model and trim in your tag line.

The audio and climate control seem logical and intuitive to me. All my climate and seat controls are set to Auto and there has not been any warm air then cold air with fogging situations. I may have an opportunity to test the remote start function this week and will see how it operates.

 

I just spent two hours with a dealer service rep' and then with Acura Client Relations. They are aware of the cold air from the defrost vents once the "auto" set temperature is achieved....But, they say it's designed to do that, which is my mind is a major design flaw. Acura's response was, once the desired "auto" temperature is achieved, manually change the system from "auto" to one of the other vent settings and the outside air will no longer come up the windshield...and of course that means resetting the system to "auto" again before you turn the car off unless you want to have to restart the car after using the remote start feature before you can use the heated seats.
Acura needs to fix this....I highly encourage each of you to call Acura and demand a fix. Thanks
