Unintended acceleration reports for Prius, ES 350

08/15/2007, 9:02 AM

By Drew Johnson

As of late, the Toyota Prius has been generating complaints of unintended acceleration. First reported a year ago, several Prius owners have complained that the car will accelerate or lunge forward with no input from the driver. Toyota service technicians have dismissed the claim as a flaw in vehicle’s computer system, electronic controls or software program and put the blame on driver error or a floor mat jamming the accelerator.

But it looks as though Toyota’s unexpected acceleration problem extends beyond just the Prius model. According to the Detroit Free Press, federal regulators have stepped up an investigation into 98,454 Lexus ES 350 sedans after receiving 40 reports of unintentional acceleration, including 8 accidents, 12 injuries and several cases in which cars only stopped after an accident. Just like with the Prius accidents, Toyota told officials that the incidents were caused by loose floor mats and contends that it dealt with the flaw through a mailing to customers earlier this year.

Despite Toyota’s claims, the National Highway Traffic Safety Administration verified several of the complaints. In one such case, a man’s car accelerated to over 100 mph on a 6-mile stretch of highway. However, the NHTSA did find that the majority of the cars in the investigation had optional all-season floor mats. When improperly installed, it is possible for these rubber mats to slide under the accelerator, causing the pedal to jam.

The NHTSA also found that many of the ES 350s had the optional push button start instead of a traditional key. Some drivers tried to shut off the car during the unintended acceleration but were unable. Toyota said that the button must be held down for 3 seconds in order to shut off the engine. The investigation remains ongoing.

As Toyota tries to become the only carmaker in the world thru volume, they will experience the rude facts of rushing vehicles to market without fully testing the vehicle. 2007…record recalls and botched launches for Toyota. Heads will roll!

Remember when Audis used to do this in the 80’s? They even applied the acronym Accelerates Under Demonic Influence.

BTW, the floor mat would have to go OVER the pedal, not under. Idiots.

How long does it take a Prius to reach 100 mph?
You would have plenty of time to come up with all kinds of MacGyver solutions.

What happened if the Prius had a combo of unintentional acceleration and a failure of the Swedish Moose test? You’d have these silent, but deadly cars seeking and destroying anything with antlers.

What’s really sad though is the Toyota dealerships blaming it on floormats and leadfoots. I’m sure the possibility of floormats doing this is plausible, but avoiding any other possibilities and using the floormats as a scapegoat is ignorance.

And I didn’t even know the Prius was capable of 100 mile plus travel in a 6 mile distance. I’ve seen them speeding pretty fast on highways, but I’ve only seen them top around… 85 miles per hour? I’m presuming less than 90.

These cars must have 1000 HP or something, if the brake couldn’t overpower the engine.

Im sorry but a floor mat does not have the capability, nor the will to force a gas pedal to be depressed enough to cause an accident. Its simply impossible. It doesnt have the weight!. Put the entire floor mat so it lies on the pedal, and realize NOTHING happens. BS I tell ya. Its electrical.

my idiot boss rear ended someone in his clk230 when his floormat was over his gas pedal, every time he hit the brake the car lunged he hit the same guy twice at the same light. the moron had the car towed to fletcher jones in newport beach just to be told it was his floormat.
is the prius drive by wire?

I accelerated from a stop in a Ford Explorer and when I let off, the floormat held the acclerator halfway down. Then I applied some brake and reached down to pull the mat away.

wow….that is xxxxing scary!! I could only imagine what the Toyonda-philes would say if this were a domestic maker. No one cuts GM/Ford any slack when it comes to bad press, but we could see an article that says lexus uses the skin of baby cheetahs for leather and people would still applaud and say how much better Toyota is than GM. Come on people lets be fair!!

NOW I WANT TO SEE WHAT THE TOYOTA LOVERS ON THE FORUM HAVE TO SAY ABOUT THIS?!?!?

CarLord:
I agree that the floor mat cannot force the gas pedal down with enough force to cause an accident. It can however hold the pedal stuck if it gets wedged between the side of the gas pedal and the wheel well – it has happened to me before, and sure enough, it was a set of rubber all-season mats that caused it… wasn’t a Toyota though.
You’d have to have snail like reflexes for this to cause an accident though… the brakes on almost any car can stop it even if the accelerator is floored. Also, stomping on the pedal once or twice should free the offending pedal… worked for me.

Audi and I believe Jeep had the same problem. Haha does anyone remember the 60 minutes report on the Unintended Acceleration of the Audis, the president was blaming the customer! THEY ARE FINE CARS!! THE DRIVERS ARE STUPID!! I believe its even in some textbooks of a perfect example of what not to do in a situation like that. After that buying an Audi was almost unheard of.

Will I imagine it’s possible that this is a mechanical failure, maybe there are some drivers who hit the gas when they want the brake.

toyota is going to get some people killed.

That would scare me quite a bit…a 100 MPH and I can’t even shut the car off.

Ford_sucks – yea…I can’t even imagine what the GM haters would say. Fortunately, GM and Ford seem to be smarter than to blame the floor mats so I guess we won’t have to worry about that.

im tired of the many suckers on this site who whine and bitch and cry about how ‘when this **** happens to domestic makes noones cuts them ANY slack, but when it happens to toyota everyone sympathizes’. WAKE THE **** UP. look at these comments, tons of people are criticizing, most aren’t cutting any slack, stop ****ing complaining.

and Sabon, you’re right, noone with a Prius has posted this being an issue. My mom drives a 2005 Prius and it has NEVER been an problem. but you’d all rather whine.

No the Prius drivers are all out committing vandalism by beating every H2 or H3 with toxic spray paint and setting them on fire! LOL

Wow, that sucks for the people involved. I agree that a mat can cause a gas pedal to stick, but 40 similar complaints? And who knows how many unreported incidents?

To the people complaining about using simple reflexes to deal with the situation, need i remind you of the primary clientele for the two cars mentioned? Not exactly driving enthusiasts. To many of them, driving is uneasy work. To most of us (as car enthusiasts) it would seem common sense to put the vehicle in neutral or apply all the brakes if it won’t turn off.

In any event, I think it sucked on Toyota’s part to not at least be a little more diplomatic in an already unpleasant situation. It comes across as them seeing their image (or profit) as being more valuable than these people and potentially more. Besides, I thought they were nose deep in profits?

The new Jeep Wranglers don’t accelerate, they do the opposite – they just shut down on the highway when you’re already going 100 mph, therefore losing access to the power component of the brakes and steering. Equally interesting though….

I’m sure Congress is working on a solution: ban the use of all floor mats! Floor mats are very evil and they kill people.

The thing about the Japanese companies is that they will acknowledge the problem and fix it bc they give a damn about their rep
Ford on the other hand will give you a hard time if you bought a brand new Focus and your tranny and master cylinder go in the first 4 months
I would rather take an over accelerating ES 350 over any domestic offering any day

It is not the damn floor mats and it affects more than just the models mentioned here. My father in law bought a new Avalon and had intermittant problems with unintended acceleration. Toyota was terrible in their dealing with him forcing him to loose thousands of dollars trading in for a different car. They refused to consider that the car had a problem. I hope they get to the bottom of the problem instead of just blaming it on floor mats or some other unrelated problem. There is a serious flaw in the throttle somewhere that is affecting Toyota across the board.

I hope this knocks some of the arrogance out of Toyota and makes the company suffer a little bit.

Toyota is not dealing with this problem and it has been going on for a couple of years. Toyota maybe used to care about their reputation, but now it is all about selling more cars and have gotten too big to see the big picture.

If you would take a severely flawed car that could have dangerous unintended accelleration that might hurt innocent bystanders then Toyota management are not the only ones with their heads up their asses.
