Replying to: wwest (Dec 06, 2008 6:09 pm) If I fail to secure my mats (Lexus already provides a very secure clip for the drivers mat), that's my fault and I don't see a need for this to be programmed into the car. There's already too much meddling on part of car manufacturers protecting themselves from liability when they should be concentrating on building safer, more efficient and durable cars that are fun to drive and easy to live with using inherently safe designs. I'm all for the proven benefits of a well-behaved stability control and ABS system, but sometimes it's taken a bit overboard, and preventing simultaneous throttle and brake control would be one of those times. I don't see a significant safety benefit for the benefit you are proposing. I don't want to release any more control of my throttle to an electronic lawyer than I have to for optimal functioning. |

Replying to: la4mead (Dec 06, 2008 8:23 pm) But, also obviously, "this model" could be subject to the problem as well. "For too little benefit.." Tell that to someone who has actually driven into a busy intersection, or worse, due to a carpet mat, luckily I'm not one of those. And it isn't necessarily the OEM floor mat/carpet that results in the problem, it may very well be, moreso, the aftermarket "weather" mat. "they should be concentrating on building safer.." And if "this" isn't about safety then how would you classify it...?? And tell me, just when might you be noticing that the gas pedal doesn't respond when the brakes are applied...?? Totally, TOTALLY, non-obtrusive...FAILSAFE....!! "I'm all for the proven benefits of a well-behaved stability control and ABS system,...." PROVEN BENEFITS........ WELL-BEHAVED..... Really...??!!

Replying to: wwest (Dec 07, 2008 9:33 am) I sort of wondered if you meant to park this in the Lexus RX area. We could move it to Automotive News or Maintenance & Repair. That way you'd attract the Audi crowd too.  Ditto your ABS discussion. |

Replying to: wwest (Dec 07, 2008 9:33 am) I'd need to see hard data on how much this could help provide a safer environment for everyone it affects. Your argument does not convince me that deleting simultaneous brake and accelerator control would be totally unobtrusive. Perhaps the title should be "slipping aftermarket mat safety" and it would help more accurately describe the problem of the discussion. I'm more concerned about the soda can under the brake. But I don't drink soda, and not proposing to outlaw beverage containers in cars.

Replying to: la4mead (Dec 07, 2008 10:12 am) Locking out the gas feed with brake application might put an end to those also. I'm pretty sure the incident in teh Mazda minivan involved the OEM mats, I don't remember what the resolution was other than discovering the problem and moving the mats back and notifying the owner. "I need to see hard data...." Why, do you have doubts that the problem exists...?? Or have doubts that it is potentially life threatening..?? Perhaps you could tell us under what/which circumstances you think/feel it might be obtrusive..?? Most vehicles that have the brake/park lock also have a manual bypass method, maybe that would please you in this case..?? |

Replying to: wwest (Dec 06, 2008 6:09 pm) I bought my 2005 Tacoma about 2 months ago. I have experienced this problem three times now. The last time being tonight after picking up my daughter at work. The truck was accelerating and I was literally standing on the brake and the engine was racing and would not stop. I through it into Neutral and it sounded like it was going to explode! I have no rugs in my vehicle, it did not come with any, and I was going to get the all weather mats, but have not bought them yet. The cruise control was not engaged. I do consider myself to be a fairly experienced driver, I use to race a 70 Chevelle in the 1/4 mile (This was many years ago.), if I did not have such experience I am sure I would have ran the car up a tree or something. I am scared, I have beat cancer twice and Ill be damned if I am going to let a faulty Tacoma take me out! The issue is real! does anyone know a way to fix the issue? Is there a mod that locks out the gas feed with brake application, if not can this be done? I can make my car duplicate this issue yet nothing is getting done! What steps should I take next anyone? Thank you!

Replying to: tidester (Apr 01, 2009 10:29 am) It doesn't have an aftermarket cruise, alarm, obstruction (carpet, plastic panel, loose bolt, cable, clamp, misplaced heater duct, tire iron, water bottle) or anything like that? I know it sounds extremely silly to look for the obvious, but it could be anything. If there's anything else like a throttle cable or cruise servo, or even the engine cover or throttle itself... It could be anything from the pedal to the EFI. I'd be determined to find it right away, rather than in fear of it being unsafe. Maybe a search on the Tacoma forum might reveal if other owners of that model had a problem, and their solution. What if it is inherint in an electronic drive-by-wire? That surely would come up by now, unless you're the first person it's happened to. I hope you find your culprit. I'm pretty sure you will now that you have the incentive of a possible runaway truck. But it's most likely to be something obvious. But I feel for you. My mom had two Mavericks!  They both had differing "runaway" car problems. The '70 250CID I6 and a '72 "GRABBER" 302 V8. A combination of a weak auto shift linkage and hand brake that couldn't hold the car on level ground no matter how hard you pulled, and a very determined idle. My mom didn't learn with the first one, and got another that was worse because it had the torque to pin you in after it fell in "Drive" or "Reverse" as you were getting in or out of an idling car. One time, I heard my mom screaming, and there were 4 big guys from her apartment building picking up the rear of the car. It was off the ground running in gear. When they dropped it back on the ground, it ran into the apartment building. They were busy little cars. Ford's fix came in the mail, unsolicited. It was an ugly sticker you're supposed to stick on the dash. It said something like "Do not leave any car idling in Park". Then there's my dad's '70 Hornet SST. I was a 15 year old with a learner's permit when the Hornet's throttle cable broke. The pedal fell under my foot, and I pried my foot under it. But it was loose and so was the engine. The throttle opens all the way when the cable breaks on many old models. The car lept forward, chirped in "first" and right through a red light in a busy section of the San Fernando Valley. It screamed at redline 1-2, then into 3rd. I was going 75 before I got the ignition to cut. I couldn't believe they could make cars that way, even as a youngster. And it didn't have "power" brakes, either. Those were the days.  Not trying to belittle the concern for safety. I wouldn't want to put up with it, either. I'm curious to hear about it.
