Toyota Yaris Interior and Passenger Comfort Concerns



  • girlcarbuildergirlcarbuilder Baton Rouge, LAPosts: 218
    Hello everyone. Thanks for the heads up on the leaf/mold problem. Been looking at the Yaris as a replacement for higher mileage fleet units. Does not matter what you buy, there are times you have to go back and redesign something. We plan to rent one for a week before buying the first one, but we count on feedback from those who have already bought.

    Mold is clearly getting in from rotting stuff. Keeping leaves cleaned out from the outside vent system is the answer. If we buy, it will go to our shop immediately for screens to be made and installed. Not uncommon for those vent openings to be under sheet metal or plastic cowl vents. I have even seen them inside fender wells!

    As a note, cabin air filters did not come out until recently. If you can install one, do. It is easier to replace one than to have to rip out a clogged evap core and pay someone like me a ton of money to do so!

    I do have the same issue with my 07 Yaris I took for the car to Northridge Toyota The third time on June 5th 2009 They want to charge me because my car is over 52,000 my warranty is up and they told would charge me to diagnostic fee for the same issue on the car has been repaired under the warranty twice.I declined,and
    I escalated to Toyota Motors They get in the same position as the dealers saying the following : The dealership determined that the failure was not a factory defect rather it is a customer related problem. Mr XX is leaving his car in a unprotected area. The drain hoses for the a/c on his Yaris are being plugged by foriegn debris causing the water to back up in the evaporator and is causing the leak into his vehicle. He was told on both occassions that this is not a warrantable issue outside influences are not covered by Toyota. On his two previous appointments the debris was cleaned out of his vehicle as a Goodwill gesture from Northridge Toyota and the Factory. He has complained to Toyota Motor Sales and Toyota has turned him down for any Warranty assistance. Mr XX Yaris is now out of the Factory Warranty.
    Knowing that I went to different Dealership : Thanks to service Advisor and his mechanic explained me the issue why it get debris inside the a/c box I understood clearly is a manufacturer issue because if you put anything in your glove compartment when you have the A/C button in circulation mode the A/C Box sucks air inside of the box causing with the time the drain plug be clogged and the fluid will leak inside the passenger side under the carpet.In order the A/C drain plug don't get clogged you can't put anything inside the glove compartment.
    This is Lemon issue affecting most of the Toyota Yaris Hatchback 07-up
    If you guys get the same issue as my self hit me up for legal referal against Toyota Motors.

    Hmmm, mold and mildew can be real problems here in the south.

    Our sale is currently in a suspense mode, ink has not hit the paper yet. We did advise parts we want the complete service manual set for our shop: not that I want to do their warranty work on my car!

    Hopefully they have resolved this issue for 09: I think I will inquire a lot more carefully for we close this deal.

    Thanks for the heads up.

    Okay, I had some time recently to look at the new Yaris on the lot to see what I could see about this issue.

    Comparing the cowl vent right below the windshield, I noticed the Yaris does not have a screen under it like the other models do. Talking to parts department, the exploded view does not indicate that it has a screen at all. That makes this car very prone to getting leaf and other trash into the a/c vent system. Also, many cars have been made this way in the past! I recall old Volkswagens to be that way.

    After seeing this, I would do the following. Remove the cowl plastic vent and glue a piece of nylon screen material inside it. I suspect silicone will work as a glue. Clothes pins make nice clamps for little projects like this. Test the silicone first on the inside to make sure it will stick to the plastic. Allow it to set up for 24 hours then replace. Total repair time will be about 48 hours. 24 hours to allow testing of your glue material.

    With or without that screen, I have seen many people allow trash to build up around that vent. This causes nothing but problems long term. Keep that screen/vent cleaned out. Avoid parking under shedding trees. That is tough for those of us who love trees. Otherwise, cover that vent up, install a screen whatever.

    They tell me that the 09 has an optional cabin air filter available: I recommend you get one to keep junk out of the evap core that comes from the cabin area.

    We all already know about the sprays that "make it smell better." But the best action here is prevention. Oh, it also pays run outside air at times to dry that evap box out.

    My 2007 Yaris hatchback comes with a slot for the cabin air filter. It is located behind the glove box. I have two on order. Paid about $20 for both of them from an Ebay store. I got the second one for my daughter's 2008 Yaris Sedan.
  • girlcarbuildergirlcarbuilder Baton Rouge, LAPosts: 218
    Just remember that most of this problem is coming from the outside vent that does not have a screen.

    Our new car is being bought 400 miles away from here. that dealer will be running the down payment shortly on plastic. As soon as the fun is done and it gets home, about the 20th, I will be looking into getting an outside screen set up for it. Will post how it comes out.

    Thanks for the info on the filter price. Far cry from $24 a piece at the dealer.
  • I had the same problem with my Ford Escort wagon. I learned to clean out the cabin air intake tunnel with a vacuum hose.

    I was annoyed to learn that Toyota did not install the cabin air filter in the US version of the Toyota Yaris. I learned that the filter was missing when Lube Stop tried to check the air filter at 12,000 miles. But the Toyota Yaris air filter is not a HEPA filter. Mold spores will pass through a new Toyota Yaris air filter.

    The Toyota Yaris has a better designed cabin air intake than my 1994 Ford Escort. My Ford Escort has a cabin air intake tunnel that clogged with leaves. I had to use a vacuum cleaner hose to get out the leaves. The Ford dealer had the nerve to suggest that I buy a vehicle cover to prevent leaves from getting in the cabin air intake.

    The main sections of both of my 2007 Toyota Yaris 3 door liftback are covered with nylon screening. I did not notice there is secondary air intake that cannot be seen without opening the hood. That secondary air intake is without a screen. Thanks for the warning. It is a good idea to clean the area in front of the air intake of leaves that build up. It sounds like a good idea to glue a piece of nylon screening on the outside of the secondary air intake.

    Since there has been zero mention of the main cabin air intake having a nylon screen, I wonder if there is a difference between those vehicles that have the Optional Winter Package in how the cabin air intake is protected? My guess is that the uncovered air intake is a back up in-case the main cabin air intake is covered with snow or ice.

    Update since purchase of our 09 Yaris. Yup, sure enough the mold problem began to show its ugly head when we first started to have several days of heavy rain here. Turns out it is not climate control issue after all.

    Figured it out immediately. The problem is the floor mats are carpet! What they have for carpet is not carpet, but rather cheap fuzz. Get it wet, it grows molds! We added rubber floor mats on top of the other floor mats from Wal-Mart. They are the stiff ones with deep grooves to keep water from getting into the carpet/floor. You must take extra care to cut the mats to clear all pedals, the mat must also stay under the pedals and be very sure that each time you get in, the mat is pulled back in place to prevent it from jamming any pedals like the gas pedal. I also left the tab on top of the mat where it was stapled there so it would hit the bottom of the steering column and prevent the mat from folding up under the pedals any.

    If the mat gets to a point it folds up, replace it immediately for it has become a safety hazard. Also to this point, do not use flimsy thin mats that fold up easily. If it folds at all, it can jam a gas pedal giving you a run away car. Never allow the mat to be on top of the pedals either. Use common sense on this.

    There has been one fatal accident already in California with a Lexus this year with aftermarket mats. Toyota currently does not make an all season floor mat for the Yaris.

    who are wondering about Toyota's ECU operations. Whether it's an electronic failure of some kind going on regarding the out-of-control acceleration issue.

    I would guess that it's not electronic, though Toyota needs to really slam that issue head on at it's design centers and find out if anything might be going on.

    I think it's simply a bad floor matt design issue that caused this problem. That CHP Officer didn't know about the 3-second push in required on the stop-start button that would've turned off his loaner Lexus' motor. So sad. He could've also put the car's tranny in neutral.

    What is being discussed is that he apparently only tried to jam the brake pedal down and couldn't get up enough leg strength to stop the out-of-control car.

    Car manufacters have been cutting costs for years wherever they can. Older people can recall the plush loop carpet with rubber floor mats that had hooks on the backside to hold them down. What is being made now a days is no where close to that. So how do they expect a " cheap fuzz" carpet to hold down a floor mat? They put in one big hook to hold it in place. Fine for OEM, but when someone changes that floor mat out for an aftermarket for what ever the reason, problems occur. So we can not totally blame the change, yet we demand cars not to go up in price....ooooppps I am guilty as well!

    Even years ago, with the good carpet and mats, you still had to look down and shift that mat back at times. Want proof of poor maintenance habits to back this up? Walk a junk yard sometime. The number one reason for a car to be junked before its time is poor maintenance aka I don't have time to relocate the floor mat or check the tires behavior. Tire Pressure Monitors are now mandatory because of that. Guess if we have too many incidents of this, we will soon have floor mat sensors as well. We watch our lights, tires, seatbelts and mats all of the time. Simple sounding, but can get you in big trouble everytime. Does not matter who the car belongs to, you should always check it out before you drive it! Basic drivers ed from years ago.

    So any way, the main thing that surprised me was the officer never thought to turn the key off! Something we were taught years ago in drivers ed. Seems the newer generation is not being taught this....but when it comes to a high strung V6 in a Japanese product being floor boarded, you have little time to think this out. Screw saving the tranny or the engine at this point, it is your life you need to save. Hit the switch and hang on to the steering wheel for power steering will be gone. Before someone asks, yes I have been there and done that! Mechanics have seen it all....most! Uncle Murphy even has a few for us! Pray as well!

    some simple 1-2-3 mechanics steps of stopping an out-of-control car. Push the on-off start button in for at least 3 seconds will turn it off...put the automatic gearshift in neutral and you can brke the car to a stop in no time......turn the key off, if your car is operated by a key start system, otherwise just push the on-off start button in for 3 seconds, as has already been mentioned on this post...go over these in your mind several might think you're prepared but once your car is accelerating you might think otherwise. Go over the procedures to stop your car a few times, it might save your life if you're so unfortunate that one of these incidents should happen to you!

    To all 2007 Yaris owners......if your car is less than 3 years old and 36000
    miles this is a covered problem with Toyota . Go to and
    ask for help in getting a copy of the Toyota Technical Service Bulletin (TSB)
    that covers this problem....Take it to the dealer and COMPLAIN....COMPLAIN
    and when they tell you that it is not covered, whop out the TSB and complain
    It seems that they will at first try to shine you on but stand your ground
    with your TSB INHAND. Also check TSB #EG048-07 if it applies to your
    car SPEND the miniscule amount to replace part #77248-52060 and #
    77219-21010...... $25 worth of parts can avoid a $1200 failure.....its called

    Okay, I looked at your message which is about the evap system not the a/c odor.

    First, if I am not mistaken air pollution control is federally mandated to work for a certain period of time....50K miles. It may be more now. It would take a phone call to my attorney to know for sure.

    Second, back to the a/c system. As I stated before in a previous post and which may not apply to your year, we found that Toyota did not supply the air filter in the a/c system. Strike one. Second strike is there is no screen in the outside air intake system. Strike two. The source we discover for the mold smell turned out to be the carpet not the a/c which is picking up the smell from the carpet. This became very apparent after the first bad rain storm. The cause is the carpet is no longer coated with a plastic backing and neither is the floor mat! Strike three!

    Our answer was to carefully cut some heavy duty Wal-Mart floor mats and install. The mats are deep grooved to catch water. Good bye mold smell. But wait along comes a floor mat recall on other Toyota models! We paid attention for sure. The new carpet does not have much fiber for floor mats to hook into and stay in place. So they slip around. You need to be watchful and keep the mat pulled back. We have a standard tranny so when it gets too far forward, the clutch switch does not engage. Our signal to pull the mat back. We also have the mat cut so to hit the steering column and it was already shaped as to not interfere with the acceraltor.

    A lot of common sense and careful looking at things goes a long way. Thanks on the water problem. I may start running a bit of alcohol once or twice a year since we do store ours at times. It is a 2009 3 dr hatchback. Cars are not as carefree driving as most people want them to be. That is how mechanics make their money, driver not watching under the hood!

    I want to answer you as far I know on your statment:

    Second, back to the a/c system. As I stated before in a previous post and which may not apply to your year, we found that Toyota did not supply the air filter in the a/c system. Strike one. Second strike is there is no screen in the outside air intake system. Strike two.

    I'm agree with with 2 strikes but not with the third one.
    The mold Odor came from the vents as matter fact I went to the dealer and they showed me how to clean it.After the odor went away .But later come back,as far goes with the carpet we washed and cleaned no issues with it.
    If is any further information you need let me know
  • girlcarbuildergirlcarbuilder Baton Rouge, LAPosts: 218
    We live in a rainy LA area. I am very sensitive to mold. Waiting to wash carpet to resolve a mold smell is not an option for me. I would have to replace it. Source in this case of water was from feet and umbrellas, so mold smell was clearly the carpet. Exactly what my nose said! It happen after a few days of rain.

    I read your previous posts again, just now. Trash in the a/c system will do it also. Yup, now you have a third thing to watch in addition to what you already know! I also noted the other Toyota models had cowl vent screens, but not the Yaris prior to our purchase. This kind of info is invaluable to buyers who look first on Edmunds.

    Keep me posted on how yours does long term. Just flipped 15K miles. It was your original post that put me on alert about this problem before we even bought the car! Hence we avoid parking under trees. We also keep the vents clear and have a filter in the a/c. Watch your wet umbrellas and feet.

    I'm fairly sure that Toyota made a mistake calculating the cargo space of the Yaris. Since I'm trying to decide which car to buy, this is an issue. My brother has a Yaris hatch and he sent me the measurements.

    The published cargo space is 25.7 for the Yaris and 41.9 for the Fit, but it doesn't add up. Just going on the max dimensions (which has some fallacies, but at least is roughly comparable), the two are nearly identical. Did Toyota make a mistake and no one (all the car review sites) has bothered to check?

    52.21 inches * 51.61 inches * 35.85 inches = 55.9 cu ft


    100 cm * 146 cm * 103 cm = 53 cu ft

  • bamacarbamacar Posts: 749
    I assume you are comparing Hatch to Hatch and not sedan. The clear difference comes behind the rear seats. One look and it is obvious. Actually Toyota claims 9.3 cubic feet behind the rear seats. Honda claims 20.6 cubic feet behind the rear seat.

    If you are looking at Cargo space with the rear seats down then the Yaris and Fit are similar in the back seat area, but the clear difference is behind the rear seats. The Fit looks cavernous behind the rear seat and the Yaris looks tiny. The Fit is 11 inches longer overall than the Yaris Hatch and basically all of it is located in the cargo area.
  • twl8ntwl8n Posts: 2
    Yep, comparing hatch to hatch, rear seats down.

    My question: since the L x W x H are so similar, how did Toyota come up with a cargo space that is 1/2 of the (theoretical) volume? I don't understand how Toyota got 25.7 cu ft from what is more like 50 cu ft.

    Apparently Honda and Toyota use a different formula, and it makes the Yaris cargo space seem much smaller than it really is.

    Has anyone checked the published 25.7 cu ft for the Yaris?

    Does the Fit really have 11 inches more cargo space? An image on the Honda web site for the fit gives these numbers:

    I got these from a Honda web site:

    100 cm * 146 cm * 103 cm
    39.4 in x 57.5 in x 40.5 in

    It must be wrong. I guess the 146 number should be more like 176.

    This page in the Edmund's Fit forum (scroll about 1/2 way down):

    says the long dimension is 1720 mm or 67 inches which makes the Fit quite a bit larger.
