The go pedal used to occasionally wedge underneath the OEM floor mat in my 2001 (AE112) Corolla. Instead of lawyers-at-ten-paces I decided that I'd probably kicked it forward a bit. I recall the floor had a metal locating hook sticking up out of it that poked through a corresponding hole in the mat, presumably to stop the mat sliding forward, but this wasn't enough, and it still moved around just enough to be troublesome. Eventually just got rid of the mat and didn't look back.
It shouldn't have happened at all, though, and in my case it was fortunate that my car had that pesky third pedal (and that I knew what it was for!). I never drove a two-pedal version of that car, so NFI if they had the same issues. I expect they did.
No more floor mats. IMHO cars should have some kind of barrier underneath the driver seat, too, to stop things sliding forward from the rear seat floor.
Some of the more modern Corollas that I've rented from time to time have had an inexplicable large gap in the dash/forward console bit between the front seats, ahead of the transmission lever, and down quite low. It concerned me that anyone truly taking advantage of their rental car might be at risk of things flying from the passenger footwell over into the driver footwell. It never happened to me, but it seemed distinctly possible. And $deity forbid that anyone actually store stuff there...
While I have frequently had mats get 'under my feet' in cars and on occasion even jam the go slightly, it is not full throttle jam as reported. Most cars do not have go pedals hinged from the floor these days. So how the mats jam them I do not know. My Landcruiser and Camry both have top hinged pedals.95 and 2004 models. The Landcruiser factory mats never cause any trouble. Surprisingly I have never had a Camry with them. [New car dealers push the accessories big time at point of sale as sometimes they make more money on them than on the car!]
The clutch pedal however solves all of the problems,,, if you do not panic as many seem too.
But it seems what is causing most accidents is the STUPID push button start. And 3-5 sec STOP delay. For mine EVERY vehicle fitted with this garbage [of all makes] should be recalled and fit an ignition key and lock. And the government regulators world wide who allowed this garbage should be made to count paperclips for the rest of their lifes.
Though the dozens of in traffic fender benders probably caused by this is still a HUGE concern. Late Toyotas are far less popular as used cars because of this. Though I suspect other makes too may have these problems besides the named ones. Too much electronics in an environment very alien to electronics. Dirt, heat, viabration.
That caused problems on a late Hilux belonging to an aquaintance, occasionally when he drove on a rough dirt road it would stop. Then normally start again though sometimes ran strangely. Since this bloke is a farmer it was a major concern. In the end after about 6 visits to the dealer [who did try] they eventually found a crook ECU. Replaced it and so far ok. It may have been the viabration or just the dust in the car. Whatever it should not happen but it is an alien environment for electronics.
Most repairers will tell similar problems, and unless they happen in your care near impossible to find. And worse the so called 'experts' often have no more idea than the average repairer. This is large auto elec shops and genuine dealers. The number of dodgy fixes for some of these dramas is putting a resistor in the loom. Putting the ECU in the fridge overnight! They do work but who knows how long. The above is for a continually rich mixture on a popular make. Something that is rife on many makes and models. That and dodgey transmission changes. Is it the ECU, is it a dirty connection, is it a crook sensor or sender? Or in one case the harness had a crook wire. This after we cleaned the engine it would not start again. They replaced the harness,, a week after and the car ran better than it had before.
Even a dodgey alternator, or battery can cause grief. this a battery that starts the car, or an alternator that still charges.
Cleaning engines can be a drama. Water gets where is should not and causes all sorts of grief. One particular make amazes me they ever run in the rain! As they are a real drama when you clean the engine.Though I have had them running really poorly on a wet day. As a used car dealer I have had to refuse to fix it. It is a manufacturing fault.
