Toyota Halts Sales of Popular Models - Accelerator Stuck Problem Recall



  • I think you just said that Toyota has an "unintended acceleration" problem that may affect a bunch of their vehicles. They either don't know, or won't tell, what the real problem is, and therefore a lot of folks have legimate concerns about their Toyota vehicles.

    Couldn't have said it better myself!

    What this discussion isn't:
    1. A "dance on the grave of Toyota" topic - if you're only here to revel in the misery of the company or Toyota vehicle owners, you're in the wrong place. Taking delight in the misfortune of others isn't welcome anywhere in our Forums.

    2. A psychiatrist's office - it's not the place to tell others that their fears are irrational. Keep in mind that others may have a different level of risk tolerance than you do, and please respect that difference.

    No. Try reversing the letters "i" and "e" in the word "rivet" and you might get the joke....
    So serious!
  • I called my dealer's (repair dept) on Wednesday 1/27/10 to ask if my car was being recalled. He asked for my VIN number. I didn't know it. He asked for my telephone number. I gave it to him. He supposedly looked it up and said "don' t worry, your car is fine". I told him I was going to Connecticut that afternoon, and he said "your car is new, you will have no problem". On Saturday I checked the website and found that my car had a VIN number that matched the recalls. This man purposely lied to me.
  • I took his word that my car was fine.

    This man purposely lied to me.

    How do you know that for sure? What motivation does he have to purposely lie? You're assuming that your phone number accurately matches up with your VIN number in the database he's checking. Why not call him back with the VIN number and see if it matches what you found on the other website? If he still says no, you've got some other evidence that you can question him about.
  • Apparently if the Camry built in Kentucky has a VIN beginning with 4T1 it may have a Denso pedal.

    At least my 2010 SE does.

    A few, a very few, people have reported a problem.

    I am driving a 2006 Avalon XLS with a CTS pedal and it has 46,000 miles on it. I tried stacking floor mats and I was not able to make the mats reach anywhere near the bottom of the gas pedal.

    I have noticed no change at all in the gas pedal function since early 2006. I figure the odds on my car having a problem with the pedal are about one in millions and millions of Toyotas sold since 2006. It's a car and a mechanical object that can break at any time, so I have to be prepared when I'm behind the wheel.

    Be prepared. The Boy Scouts have a good motto don't you know.

    And I just had the oil hose replaced under the recall, so that's good to go for at least another 46,000 miles I figure. The old oil hose seemed to be just fine - no cracks, bulges, nothing, but if they want to give me something free I'm all for it.

    Oh well, some people expect perfection. They will always be disappointed, at least in this life.

  • isellhondasisellhondas Issaquah WashingtonPosts: 19,603
    Thank you for that. Well said!
  • I checked my pedal this morning and found I have the CTS.

    I also noticed that the side of the pedal slightly brushes against the carpet that is on the side of the center console. I don't know why they designed it to be that close to the carpet. Looks like it could stick if something got between the carpet and the pedal.

    Has anyone else noticed this?

    Lawyers Ask Court To Stop Toyota From Fixing Cars

    Their complaint “asks the Court to enjoin Toyota from implementing any fixes in the accelerator pedals of the subject vehicles without approval from the NHTSA.” To those who are not familiar with a strange language called Legalese, “enjoin” means “issue an injunction,” or, in even plainer English, “order someone to stop doing something.”

    I am just passing theses videos along for individuals to review and help explain in basic/nonprofessional language how pedal in question is assembled, functions, etc. Video is quite informative, especially if you have even a small degree of knowledge/experience about computer technology and the little bugs that can occur and can be difficult to pinpoint/and/or correct. Yes, multiple computer technology systems are undeniably a part of the sequencial steps of process in pressing gas pedal to ultimately the actual engine acceleration.

    This below video is great - done by Consumer Reports Auto Engineer on auto comparison between a Toyota and VW - HOW TO STOP YOUR TOYOTA. I did like the VW demonstration that has brake override system so vehicle can always be stopped. I do not personally like VW autos, but did like how brake override system works, and how it appears to be great safety device for any possible problems with unexplained accleration problems. AS MEDICAL PROFESSIONAL I FEEL THIS IS MUST WATCH FOR ALL OF US. ring-sudden-acceleration/17188412001/48234862001/

    Toyota is not the only auto manufacturer that has higher complaints than other manufacturers. But their complaints do seem higher than other auto manufacturers per government statistics. Since I own a 2006 RAV4, I am very interested about the issues and my own safety. My vehicle is not among the recalls, but have had intermittant minor unexplained increases of aceleration incidents - all could be controlled though. I am not sure my vehicle issues are related, but feel I must stay informed and be knowledgeable for my own safety. Presently I have no intention of trading my vehicle in. But I can not honestly say my position will not change if problems increase and/or cannot be taken care of.

    Good luck to everyone.

    I just posted message with two videos and inadvertantly sent same video twice. Please find other video below. This video is great and helps demonstrate most of sequencial steps involved for acceleration.

    CTS, while seemingly admitting to their gas pedal sticking or binding, is denying responsibility for these WOT run-a-way engine episodes. So Toyota continues, must continue, to look elsewhere for the primary causative factor.

    Until that time comes any vehicle of asian manufacture that uses the same parts and firmware design source (NipponDenso/Denso US) as Toyota/etc will remain "suspect".

    The way Denso has been known to operate in the past not even Toyota may ever know what the problem was/is, nor the FIX. I would imagine the fix will come as a "reflash" with a public announcement that the "reflash" will be to facilitate a failsafe. Failsafe will be to drive the throttle plate to idle when the brake is used but also "buried" in the reflash will be a true fix for the firmware problem that is the root cause of these current episodes.

    Does Boeing get to look at, certify, the firmware source code from a parts vendor..?? Possibly....

    But I rather doubt that Toyota/etc has access to NipponDenso/Denso US firmware source code, and less likely certification ability. Toyota/etc probably doesn't even have the talent required for firmware source code validation/certification even given access.

    Then there remains the question of anomalous behavior, as yet undiscovered anomalous behavior, possibly, of the microprocessor, computing engine, and surrounding/supporting hardware. Anomalous behavior just random enough to be almost, if not altogether, untraceable.

    The video posted shows the CTS pedal. The Truth About Cars shows both pedals disassembled side-by-side in this video. Interesting, to me at least, is that the earlier CTS video didn't determine if there were a backup spring inside; this video shows that both suppliers have a backup spring in case one spring fails. l-assemblies-denso-unit-looks-cheaper-rumored-to-be-recalled-too/

    Obviously you have never seen an "errata" sheet for, for instance, one of the X86 processors. Over the past 30 years my software development team has independently found/discovered not just 1 or 2 of these hardware "bugs" and provided the appropriate documentation to the manufacturer so they could added to the errata sheet.

    And I'm quite sure we are no alone in this matter.

    To the point that there may be something wrong in the computer(s) that control the acceleration, I offer the computer in my washing machine. It lost its mind a week or so ago when the wash cycle was cancelled. It would not unlock the glass top on the washer. No picking new cycles and starting them would work any miracle and reboot the computer. Pushing buttons to initial new cycle or cancel would do anything.

    So I unplugged it for 10-15 minutes. Apparently on a complete restart it bootstrapped the right program into place and the Whirlpool Cabrio operates just fine--until the next time it decides to get lost when a wash cycle is cancelled.

    The parallel is that computers are programmed by someone. Despite all the best checks, hopes, prayers over the binary coding, things go wrong. A PC can be rebooted. A washing machine computer required unplugging to drain the memory (little humor there, "drain"). But a car's computer may have a quirk that only occurs on a certain input at a certain conditions within the processor and motherboard. Those are hard to find.

    When car computers have a quirk, it is a major danger. A consistent comment in the many reports in various places is that when the car was turned off, everything was back to normal on restart. To me that says not mats in all cases, that says not sticking gas pedal in all cases, but says there's another problem in some cases--scientfic method at work. So various hypotheses can be posited and tested carefully with only one variable changed to allow a conclusion.

  • I suspect the Toyota problem is more than a floor mat or mechanical accelerator pedal malfunction.

    I own an '07 Prius. For about the first 15-20,000 miles the car always shut down immediately upon depressing the power button. Since then, the engine frequently does not shut down on the first push, and my car will move forward if I take my foot off the brake. I have to push the power button a second time to stop the engine.

    The dealer could find nothing wrong and told me the problem was I should be pushing the "Park" button before pushing the Power button to turn the car off. (It says nothing about doing that in the manual.)

    I wrote to Toyota, and to my dealer, explaining I was concerned that a computer software or hardware malfunction was the cause of the problem with my Prius. They reassured me there was no danger.

    My wife and I continue to drive our car, and I'm careful to be sure the engine has actually stopped before I take my foot off the brake. However, I'm now concerned that the minor problem I'm experiencing could progress into something much more dangerous.

    I sure would like to know why my car refuses to turn off with one push of the power button, as it did when I first bought it.

    Someone asked earlier whether car companies have access to supplier component software/firmware. While I've never worked for a component supplier, I had worked for a technology supplier that sold products to the automotive industry (Toyota being just one of our customers). They do indeed have access to software/firmware. Matter of fact, they demand the access. Moreover, the majority of the time, the auto companies insist on either customizing the firmware/software themselves, or having the supplier do it under the car manufacturer's supervision or review. Further, the software/firmware is unique from car company to car company....sometimes just a little, sometimes quite a bit.

    imid...the more I hear about the accelerator "shim" fix, the less I'm convinced that it will solve the issue. While I hope it does. I'm not confident that it actually will.

    I also wonder if the safety laws and review procedures in Japan are less stringent than they are in the U.S.? Perhaps that explains why the recall doesn't affect Japan, but does affect other parts of the world where these vehicles are sold.

    Found that the Sienna also has had reports and issues due to acceleration of high speeds ! Its not been recalled but has the same scary issues as the other Toyotas, go to and check out the boards..lots of scary stories going back to 07 and cars even early years..I have an 09 and am very concerned for the saftey of my family ! Always wanted a Toyota and now have one and dont want it anymore !
  • sharonklsharonkl Posts: 660
    I am so sorry. Another WHOOPS found. Toyota did announce they were going to install Brake Override systems in new vehicles possibly 2010-2011. Have also seen reports Toyota may flash system into some of recalled medels as well, but I have not been able to confirm this statement.

    I am not sure of why this feature was not already a standard feature for Toyota and some of the other auto manufacturers. I do see some manufacturers already have this feature and personally assume those manufacturers have it for safety reasons, PR for decreasing complaint issues, etc. My personal assumption for not having would be system development, capatibility issues, issue of patent?, etc. Just not sure, and am only guessing. The actual computer flashing to install this computer brake override system doesn't take long, and once setup would be minimal cost/possibly no cost since Toyota owns the computer flashes already. But maybe Toyota charges each individual dealer for these flashes? Difficult to understand this possible cost, as Toyota would not be selling to nonaffiliated outside repair service center. .

    Please note my personal main concern about these possible unexplained acceleration complaints involve safety issues. I am medical professional so this will always be my major concern. Incidents could cause minor to serious accidents that could/possibly cause injury/possible minor to severe bodily harm/injury and possibly even death. And then you look at possible vehicle damage, and driving record implications, auto insurance implications, etc.. It appears to me this complaint carries much high risk for people safety risks than some other lodged complaints

    Incident complants do seem small when compared to number of vehicles sold, but government statistics do reveal complaints continue to be lodged over the years. These statistics do not include complaints lodged with the dealership though. Then you must also consider the number of people that do not lodge complaints. How many were valid? Etc.

    Again I apologize I did not include this additional information also. Since Toyota has had good reliability reputation I hope they will now have this isssue addressed. I still would have liked to have seen them be more proactive in the PR department addressing this negtive publicity. But seems maybe they are now.

    Personally I would like to see pro-brake override system, or equivalent on all autos/trucks/etc. Alos personally my nonprofessional opinion seems to lead me to possible multifaceted cause/s. Could pedal be improved? Maybe/sure, as most designs can always be improved, but I do have difficulty placing full blame on pedal. Scope of complaints lodged with governemnt safety agency over the years has many incidents that pedal/floor mats do not appear to be the cause/or be a sole factor. Our automobiles are now loaded with computerized systems and with that we must/should have fail safe systems installed, if for safety reasons alone. Intermittant bugs, glitzes, in computer software are difficult to find. Many/some malfunctions are not recorded in memory, and/or depends upon the actual program memory functions and retention of that information. Brake override systems, or equivalent would sure help overcome these intermittant bus/glitzes.

    Yeah, Toytoa will now have brake override systems in future! Guess those of you with recall models must check if you will get these flashes into your vehicle. Good luck, and hope all of your issues/questions will be taken care of at your dealerships to your satisfaction. Sadly for me, I do not have one of the recall models, Sure wish I did. But still am happy for those of you that do.

    Yes, pedal appears to have two springs. I accidentally sent earlier video. Later video has popup apologizing to Toyota, and this gentleman had also apologized in first video if pedal did contain two.

    I liked this demonstration. I am not sure who this gentleman was, but I thought he seemed to be fair, and not derogatory towards Toyta.

    Many thanks for sending this information along to me.

    Sorry I sent wrong bookmarked video.

    Okay, so we're about the same age and have computer backgrounds.

    Anecdotal tales do not replace evidence.

    There are more anecdotal tales of drivers pushing the gas when they thought they were pushing on the brake pedal. That's not evidence either if we're talking about hard facts and science..

    If the cars are faulty, why haven't there been more problems? Millions and millions of cars - Toyotas - and only a few documented cases. The buggiest thing out there are human beings. Right? The nut behind the wheel. Sort of like computer problems, isn't it? The end user is often the problem.

    I wonder whatever happened to my Leading Edge Model D with the ram upgraded to 640k, 2 x 5.25" floppies and no hard drive? Those were the days. Or the old CPM machines? Or my first wife. BWAAAHAHAHA.

  • wwestwwest Posts: 10,706
    "..the actual computer flashing to install this computer brake override system.."

    A true WOT/brake bypass FAILSAFE would, of design necessaty, not use the existing control computer. A simple relay circuit to open the EFI circuit would be a more proper failsafe. Or go ahead and use the "reflash" technique but provide a separate backup failsafe that only kicks in if the engine doesn't drop to idle RPM with a few hundred milliseconds of brake application.
  • I have an idea for dealing with an accelerator pedal that might stick. Tie a piece of stout cord (blind or curtain cord, for example) to the accelerator pedal. Make sure to tie it so it won't slip off, maybe both in front of and behind the rod that goes down into the floor. Tie the other end to something on the dashboard or steering column within your reach (_not_ the steering wheel). Leave some slack, but not a droopy amount. Make sure the cord can't get tangled in something important that could make it unsafe. Make sure it can't for instance be snared by your footwear. If the pedal doesn't want to come up, and you're headed into danger, yank firmly on the cord to dislodge it. This should work even if the pedal has to lift up the floor mat. Then pull over safely and call for a tow. Preferably to a dealer, who should be only too happy to rush a real repair job. CAUTION: test this sitting in your garage in neutral, don't find out whether or not it works while you're doing a hundred on the freeway in rush hour! DISCLOSURE: I'm no expert, just a driver and not even of a Toyota. This is all just a suggestion, and it's up to you and at your own risk if you do anything with it.

    the best thing an auto-manufacturer could do to ensure they don't have a run-away vehilce, is to install a mechanical override. No electronics, sensors, or software to complicate the issue and make it susceptible to "bugs". I'm not sure if the Brake-override being mentioned contains those.

    The override should physically close off the fuel-line via a valve, or physically disconnects the battery. No fuel, no spark, no go.

    whatever happened to my Leading Edge Model D

    Gone just like my $10,000 TRS 80 with five 8" floppy drives. And my $4500 HP with 292k of ram and separate floppy drive. Long before I could afford a 10 mgbyte hard drive. I have also spent hours loading old computers with paper tape code or one instruction at a time with toggle switches. Novatel and DEC all names from the past. Ferrite magnetic donut memory was my favorite to trouble shoot. Kids today have no idea.

    "..they do indeed have access to software/firmware.."

    My company has number of customer companies that have a complete design package in escrow. The escrow package connot be opened except under certain specific situations.

    In your case, even if the customer has full and complete access to your company's source code, what are the chances that they have the talent onboard to understand the sources to the level necessary fro modification and recompiling..?

    And operational firmware trouble-shooting, in the case at hand..??

    Not possible.

    I have very little doubt that Toyota/etc are relying, FULLY relying, on NipponDenso/Denso US, for that task.
