i have a 2003 tls and well i have noiced that when i have the ac on and am at a stop. the car lunges forward. i am on the brake and just waiting for the light to change and the god damn car goes forward like i took my foot off the pedal for a split second and then hit the brake.

what the **** is this?

andyone eles notice this?

normal?

 

mine too.............and the engine gets a little louder for a second..and the fan spins faster haha

i hate my car

 

why you hate your car?

 

I get that exact same thing. It feels like someone hit me in the back and I always look in my rear view mirror to make sure no one did.

 

It's normal. That's nothing but the A/C compressor kicking in. I used to always think somebody hit me from behind. I'm used to it now though. You'd think a product like Acura would be better than that.

Yeah, it's common for both the Tl and CL. It happens in every HVAC mode. Even when you're in defrost mode with the heat on. Every now and then the A/C compressor kicks in to inject a little cool air in the mix. This somehow reduces the tendancy for foging, or condensation.

When the compressor kicks in, the ECU increases the idle a tad, in order to balance the extra load on the engine.

Most mordern cars do this, but other manufacturers write code into the ECU to smooth this transistion out.

Acura doesn't.

 

The AC kicks in to dehumidify the air, not to inject cool air into the mix.
The common misconception is that the AC is for cooling, not so.
Its basically a dehumidifier, and in the winter, it acts to lower the humidity levels, and in the summer, by removing humidity, it removes heat.

Ever see in winter climates cars with foggy windows? Those are idiots who have turned off the AC or worse, are driving with the recirc on.

 

this is the only acura i've ever driven that has done this. just another little thing about this car that makes me want to get rid of it..

 

I have never noticed this. Perhaps some ecu's balance the compressor better than others?

I also had another idea. What if the coolant level was too low so that the compressor wasn't working as hard as designed. Would it appear the engine was over-compensating? Or does the ecu simply try to maintain a given rpm regardless of load? My guess would be the latter, but if that were the case, peeps shouldn't be feeling a surge.

Maybe the dealer can adjust it.

this is the last acura ill drive =P ...... unless its a nsx

theres a whole bunch of small stuff, other than the tranny, that makes me hate the car..............

when i drive like 80 mph on the highway.......the drivers side door handle rattles from the wind.....i was like wtf...

sunroof rattle

the top of the center console a/c rattles

the blackwood trim near the center glove box is falling off

the black plastic trim on the outside of the door has bubbles

far right passenger side a/c rattles

this jerking

tranny sucks

4th gear sucks

and the brakes suck

 

damn. dont get a eclipse then.

 

my 03 tl does that too..its as if someone hit me when they really didnt

 

Same here. I thought I was being paranoid at first, but it sure is consistent. I can almost count to 10 and feel it give me that little kick.

It does kinda feel like I took my foot off the brake for a split second. I even tried putting it in neutral while at a red light to see if it still gives me that little kick. No kick, and no noticeable rise in RPM's either. Weird...

 

It's Normal. There was a discussion about this last year. It's cause our A/C is soooo powerful.

 

DAMN seeing all the problems he has, I dont think I want to get a 2004 TL After All.. What do you guys think?

 

Same here. I hate it when it happens.

 

I love my car...yeah it does the little lurch when the air conditioner cycles on and off...but so what....all cars have their little quirks and hassles...but all and all....it's still a very nice car for the money. I don't think there is any other car for less than $50,000 that is nicer. If you don't like you're car...why did you buy it? I'd rather have a M5, but just can't afford the $$$$$$. And from the feedback I get from friends that have BMW's, they have a lot of problems that are very expensive to repair. Yes they are nice cars, but you have to have a lot of $$$$ to afford to buy and own one.

 

Uh, no. Cooling air also happens to remove humidity, which is why it's run even with the heat on, but in the summer, the air that comes out of the vents is cooler, because of the heat exchange from the air to the refrigerant.

Do a Google search on "refrigerant cycle" if you'd like to see more.

My car does the lunge, too. They failed (in the code) to properly time the increase in IAC with the engagement of the compressor clutch, hence the little bump forward. Depending on the response of the closed loop idle control algorithm, it may have been the best way to do it. Tough to say, without being there, and knowing if they put any real thought into it, or not.

Same here. I scared the shi$ out of 3 people crossing the street one time.

 

i thought i was the only one.

 

"If you don't like you're car...why did you buy it?"


all this happened since like 25,000 miles.....im at 40,000 now. nothin i can really do about it.

That is why you have a warranty......
Might as well use it.

 

Same here! Isn't there anything they can do for this? Make adjustments or something?

My seat is squeaking again. Different spot....not the lunge. My Ford Sport Trac does it too...I just notice it more in the TL because I drive it more.

I never noticed it in any other Acura I owned but they have always been stick...so this is my first automatic.

 

ok.....ill go to the dealer for every little squeak........i remember there was a rattle near the passenger side......it was inside and when i took it they said "it must be from the suspension work u did" and just brought my car back..........

theyre full of ****
