    mesquite57, we are on the same wavelength.

    it's even possible toyota doesn't know the extent of the "intellegence" as the firmware may be supplied by a vendor to toyota specification, and the visibiliy to that software may be restricted to a few individuals. it also spans potentially a few subsystems.

    such is life with higher levels of complex systems integration.

    knowing there is an issue and even locating it, it may take them a good deal of time and effort to develop and roll out a fix for it, and then the fix, like that for the hesitation issue may only mitigate, not resolve the issue.

    i suspect, they'd have to do some serious regression testing if they even touch the sequencing because of the number of vehicles already out there. it has to be well behaved.

    they've probably got some significant review scheduled with the programming team.

    but, my inclination, like the hesitation issue affecting a sampling of the Lexus ES line, the Sienna, the Camry, the Avalon and ? Lexus/ToyotaDBW models (population size unknown), while there's plenty of room for a ECU/TCM firmware issue contributing to the root cause for the RPM spike, it may be ultimately based in a Hardware / part issue.

    as i alluded to, they may try to mitigate this with a firmware / software update.

    i suspect, but don't know this for certain, is that this is a tact they tried with the hesitation issue (apparently non-linearity / compliance / slop on the low-end of accel based on driver foot forces at an angle during application of the pedal).

    in that case, it is apparent, a new flash (firmware load) did not appreciably help the situation. getting people to change how their foot rested on the pedal seems to bring the best results reported thus far.

    a smart engineer in my domain once pronounced: you don't throw software at essentially a hardware problem. you fix the hardware.

    exception might be a mars rover or other deep-space exploration vehicle designed specifically with that flexibility since you can't recall the craft back to mother earth once sent on it's journey to another world. ;)

    Just purchased a 2007 Toyota Camry, literally 2 weeks ago, and noticed that my carpeting was soaking wet -- dealer told me there was a cobweb in the air conditioning line. Carpet still soaked - keeping an eye on the problem. Anyone heard of this problem???
  • kiawahkiawah Posts: 3,666
    Get it back to the dealer with another opportunity to fix it, before the carpet is stained/ruined.

    For the life of me, I can't understand how a cobweb "in the air conditioning line" could result in your car's carpet becoming soaking wet.

    You didn't state whether or not the dealer removed the offending cobweb or what their solution to the problem was. I'm curious. Thanks.

    Sounds like someone is "spinning a web" of BS to me :) And if that IS true (cobwebs in the A/C line causing wet carpet), what's preventing the rest of us from having the same problem. Sounds like a poor design if that is really what happened.

    Stop for a minute!!
    If you have any knowledge of how A/C systems work you might not be so quick to point blame at the automaker.
    Any A/C system has evaporation and condensing units which work to (a)cool the interior of the car (evaporation), (b) exhaust the interior heat outside the car (condensation).
    Refrigerant, when cooled (evaporation) will cause moisture to condense on the car's interior heat exchanger--lots of moisture if ambient temp and humidity in your area are high.
    Normally this condensed moisture is released thru a drain to the exterior of the car. That's why when you look under a stopped but air conditioned car you will see water dripping on the pavement.
    If for some reason that drain becomes plugged (spider web??), condensed moisture can overflow into the car's interior.
    It's not BS, and there's no design flaw, friend.
    "Shoot first and ask questions later"---wrong!!
  • user777user777 Posts: 3,341
    agreed. an ac compressor / evaporator system is a closed system, so the faux pas is to say there is a cobweb in the a/c line.

    i believe in this context, it would be much more accurate to indicate there is blockage of the evaporator pan drain line.

    yes to the original poster, there is a tray that sits below the evaporator which will take condensate from those coils to the outside of the firewall and discharge it to the ground. foreign matter (leaf debris entering in the outside vent, or an insect like a spider could clog this drain line). sw.r.t. the latter, it's more than likely it was a crimped or a disconnected line from the pan.

    the spider story is plausible... but probable? i think unlikely, but you never know.
  • My service manager's tech told me that the new 6 speed auto transmission actually has it's own computer. It sits atop the transmission and is "allegedly" programed to the specific car that it's in. These spiking problems, IMHO are a result of bad programming somewhere.
  • mesquite57mesquite57 Posts: 59
    Concur,

    I had a real problem with the wording of the issue "a/c line had cobweb in it". I can understand blockage of the condenser drain line.
  • mesquite57mesquite57 Posts: 59
    jjthenovice,

    Or it could be a defective Electronic Controlled Transmission computer hardware or firmware or the transmission itself. Mine has been re-programmed and the transaxle compensation code (which is supposed to match the transmission to the engine) was also re-programmed to no avail. I'm still having the transmission slippage problem between 3rd and 4th gears.
  • kbondarkbondar Posts: 17
    The spider story is quite plausable, in fact. An example occurred here just last week--slightly different problem (and different spider)!!
    Spider got into the 220V contactor in our outside condensing unit (a home A/C unit). Caused a short, and fried the contactor. OAT was 95 F. and RH 90% at the time--not a good time for an A/C failure!!
    Bugs (the insect kind, that is) can and do a lot more damage than you give them credit for, sir.
    You can contribute it, and all the other "woes" you talk about to another subversive Toyota plot as much as you wish, but in this case you're dead wrong.
    The only "error" in this instance could be not describing the problem as "a blocked condensate drain line". That said, most people probably wouldn't understand what the tech was talking about. As well, why didn't this owner ask for more info if he/she was doubtful about the explanation given? Why wait until a computer was available to gripe about it in a cartalk forum??
  • user777user777 Posts: 3,341
    bugs and little animals can do lot's of damage to vehicles and electricals. :sick: i'm with you 100%. i bet that was an expensive home A/C repair.

    i apologize if my response seemed critical or that i was seemingly trying to correct anyone.

    btw: my son informs me spiders are not insects. :D

    Does your car have a sunroof? My past car had a sunroof and the drain got clogged, so any water would drain into the cabin of the car.
  • gillesmtlgillesmtl Posts: 55
    I agree a manufacturing defect is more likely the cause. Remember, the Camry has an air filter in the air inlet, so the only two ways for an insect to crawl into the air conditionning system would be to find that small drain line under the car and crawl into it, or to enter the system through the recirculation opening from the cabin.
  • user777user777 Posts: 3,341
    right thanks, i was implying that it was probably an interesting story. happens. then again, it could be legit.

    otherwise, the root cause could be a clogged sunroof drain, window or door seal, etc. so, if the pan drain has been serviced, and the floor gets wet again... there's something else to look at.

    i'm not a paranoid / conspiracy theorist-bent engineer, but i do try to understand enough about my vehicle to make an assessment of whether a service manager or tech is dealing straight with me or not (specially when I have to pay for the repair).

    but, even if I don't have to pay, since my wife couldn't care less, it's my responsibility to have knowlege of what's been done to the car and what might be a problem later.

    i don't need to be an expert in all things, just better informed of what's really going on.

    we've all heard "tall tales" from owners where what was said by the service rep couldn't possibly be true.

    I Have 10,000 miles on my 2007 Camry Se model and I hate the car. I am battling it out with Toyota about my Camry. I feel like I dont have any rights and I am stuck with this car.The car is just weird, I have hesitation some days and not other just really those days you need the power and it really hesitates on me, almost a saftey problem. And also the cruise control sucks, the car is always shifty gears never stays in 5th gear and even on some super hot days the car has a problem keeping up with 70mph. Well next week a Toyota rep is suppose to meet with me about my car that is if he can find the problem, But i was just wondering anybody out there in Camry land knows what i am talking about and how I feel about the whole thing? Thanks
  • damon34damon34 Posts: 124
    Plus I probley get 2 to 3 people a week asking me about my car and how I like it and I just started telling everybody I hate the car and I wouldnt ever buy another one. They are nice cars but they have serious issues with the drive train or just the computer I guess.

    "...my son informs me spiders are not insects."

    Arachnids, not insects. Insects have six legs. Arachnids have eight. Be real nice to the kid. He's so smart he'll probably eventually be filthy rich. It'd be nice to be on his good side.
  • damon34damon34 Posts: 124
    I was just wondering if the hesitation or your camry has gotten better or worse. Thanks
  • gene22gene22 Posts: 34
    I have really avoided saying anything, but all I hear over and over is "This is not fair" (my wording).

    Just because Toyota did something for another customer, they should not be obligated to do it for you. They made a choice in that situation. They are now at liberty to make a different choice in another situation. Agreed, they may not be making the right choice, but it should NOT be tied to what they did for others.

    Would you feel better if they went back to those "other folks" and changed the deal so it matched yours?

    What Toyota did with them has little to do with you.

    Still, YOU have the choice to not do business with them, though it is sad to see the basis for the decision on Toyota not treating you the same as some other guy. Still, you can make your own choice.
  • soooooo , 92 camry , 2.2 . out of oil and driven two blocks . ( not mine ) got the car back home and it will turn over but will not run . i have spark , nothing squeals or clanks . any ideas ?
  • gillesmtlgillesmtl Posts: 55
    I stand corrected.

    I should have known it was easier to crawl into a drain tube only 3/8 of an inch in diameter with at least 8 legs.
  • kdhspyderkdhspyder Posts: 7,160
    The hesitation question is being hashed out here and elsewhere. Regarding the cruise control - that's a new one AFAIK - it's the same system that has been in millions of other Toyota's for 10+ yrs so you might have to explain that more.

    Keeping up at 70 mph? That's also a new one. Both the 4c and the V6 are plenty powerful enough ( over-powered for many users ) at cruising speed so a little more explanation might be in order here also.
  • damon34damon34 Posts: 124
    I guess what I mean by cruise control for the car to keep it at a set speed it is always shifting from 3th 4th and 5th gear it is always shifting gears to keep it at the speed and it doesnt take much of a incline for it to shift.The car is hardly ever in 5th gear. Sometimes it is hard for the car to keep at 70mph it is almost like i am hauling a trailer or something. You can keep it going but it takes alot of gas and the tranny shifting alot up and down. The car didnt always do this. LIke i said i have 10,000miles on it. I was just wondering what toyota is doing about this because the dealerships dont know what to do
  • njeraldnjerald Posts: 688
    My '07 XLE 4 cyl. with 3,500 miles has no cruise control, hesitation or power problems.

    I did 150 highway miles this afternoon at 75-77 mph with A/C on. 95% of the time in 5th gear but shifted down to 4th going up hills. 73 degrees outside. With 2 adults and golf clubs, 32.1 mpg indicated on the trip.

    I have this same cruise control situation, with our 2007 4 cyl LE.

    I've just recently started putting some serious highway miles on the car every weekend, and have experienced this issue of significant shifting between 5,4,3rd......even on relatively flat rolling interstates.

    At first I thought the car was either underpowered (and/or overgeared) and didn't have enough HP (at the wheels) to overcome the 70mph wind resistance with the relatively slow RPM. But then I drove without the cruise, and if I drive gingerly on the accelerator, it will pretty much stay in 5th gear.....varying a couple mph. That leads me to suspect that the problem is that the cruise control is just too demanding for the available 4cyl HP. If it senses the speed is slowing, it applies continual additional throttle to catch up......forcing the car to downshift because of the throttle position. This keeps the car right at the speed selected, but at the cost of significant transmission shifting.

    I did a short stint(not enough to be conclusive)cruising at 80mph, which obviously had a higher engine RPM, and it had less shifting. My guess is it's higher up the power/torque curve and the engine could deliver the needed power at the wheels.

    I haven't tried cruising at 55 yet, it could be better because of less wind resistance, but could also be worse because of slower yet RPM (lower torque).

    Also wanted to test it without the a/c on, to see how much of a difference that would make.

    you realize, they made their choice, entered into a contract with a company by doing business with them, and now have a defective product to show for it.

    by choice you mean they can sell their brand new vehicle at a loss and move on?
  • user777user777 Posts: 3,341
    if some people have no problem there while others do, sounds like a defective cruise control unit - plain and simple or ECU or TCM. don't know the level of integration there.

    it would seem doubtful that your speed or the number of passengers in the vehicle should result in torque convertor lockup/unlock and shifting on flat-level roadways, be it at 55, 70 or 80.

    that is a very odd observation.

    while a manufacturer or service rep may claim situational hesitation and RPM flairing during up-shift is "normal" or by design (?), cruise control with erratic shifting is a very overt problem.

    get the service manager in the car and take him/her on the highway for a good "cruise".

    Guess I'll pick up where I left off the last time.

    I was bringing my car in for the manual computer/pressure test on the transmission, which by the way was done....the car was adjusted, cleared and reprogrammed. (Reprogrammed for the second time I might add) The car worked wonderfully for about 30 minutes, then back to the same, slipping...spiking, whatever.

    I brought the car back the next morning. Apparently Toyota told my dealership they had several tests they needed them to conduct which would take 4 days, but told my dealership they would not pay for me a rental, nice customer service, huh?) Anyway, the dealership paid for the rental, and ended up with the car for a week and a half. They ended up replacing the valve body. I picked it up yesterday, and as soon as I was pulling out of the parking lot, same thing - slipping/spiking...whatever. I called the dealership, they are going to call Toyota.

    I'm about as stressed out as a person can get, and I've had just about enough, so I will be sending all of my paperwork to the Texas Motor Vehicle Division this week to file a Lemon Law Complaint.

    To those of you who haven't had any problems, I envy you. I love this car (except for the defect it has of course), and actually since it's loaded out, it's the nicest car I've ever owned, but I've had about all I can take. The dealership has had this car in their service department for almost the same amount of time I've owned it, which for anything you purchase is ridiculous.

    :lemon:

    It's apparent that the new Camry is having some problems, but this is somewhat expected with a new model. Personally, I would never buy a new model year vehicle - period. Even with the substantial amount of testing done by the manufacturer, owners always end up being the Beta testers for the car.

    Historically, Toyota has always backed up their products very well. What I find interesting on this board is the apparent "head in the sand" attitude of salespersons and dealers. Saying it's "normal operation" just doesn't cut it for someone who just spent $20K+ on a vehicle, as there are other vehicles out there for equal to or less money that don't exhibit such behavior.

    Adaptive automatic transmissions with fuzzy logic have been in use for over a decade without any major issues. Why Toyota is having this problem is a mystery, especially given their engineering expertise.
