Mitsubishi Montero Sudden Acceleration Accidents [MERGED]

[zap.FREEDOM]

Finally got to drive the new Montero Sport.

All I can say is: what a load of crock these Sudden Acceleration incidents are.

First off... this car is powerful. Really powerful. And the turbo kicks in like a mule when it comes on boost. I can believe that an incautious driver could be caught off guard by the sudden rush of torque and maybe have an accident if they were driving the rear-wheel drive variant in the rain.

But there are a few problems with the idea of sudden acceleration occuring with the Montero.

1. The torque builds up slowly. In stock tune, the 4D56T makes almost no power off-idle. Run it from idle to redline in gear and it feels sluggish until you hit about 2,500 rpm... at which point it FINALLY starts to build up boost.

2. The throttle lag is pretty... laggy. If you're in "Park" when you start the vehicle, then shift it into drive with your foot flat on the floor on the pedal, there's a noticeable wait before the rpms start climbing. As long as 2-3 seconds, actually.

3. Yes, Virginia, if you step on both pedals at once, the brakes will overpower the engine. Tried it. They do.

-----

For sudden acceleration to happen on this vehicle, several things have to occur.

1. The brakes have to lose all hydraulic pressure. All of it. And there should be no trace of the failure afterwards.

1.a. One of the only ways to do that without a leak is for the brake fluid to boil while the vehicle is parked. Possibility: Pretty Unlikely For fluid to boil when parked, the vehicle will have to have been thrashed to within an inch of its life before being parked, with the driver riding the brakes over a dozen or so 100-0 km/h stops. This leaves no evidence of leaks or master cylinder problems, but the brakes will show signs of premature wear due to reckless driving.

1.b. A loss of assist due to poor vacuum will result in a very hard pedal. Not the pedal going to the floor. While this is actually more likely to happen, testimony of the drivers seem to counter this possibility.

-

2. The speed governor will have to go completely out of control, possibly a mechanical failure or a sensor issue. Possibility: Possible, but very unlikely

2.a. No forensic evidence exists for pedal sensor failure or wire-crossing.

2.b. Specific governor failures are a big unknown, but I think they're possible.

2.c. Floor mat fouling is still a big possibility.

^agree on this, nag-email few months ago ang citimotors(mitsubishi dealer) to my cousin, tinatanong kung may naeexperience ngang kakaiba dun sa montero na nabili niya, kung may sudden accelaration na kamilagruhan daw na nagaganap, then few weeks ago naman, nag-email ulit sa kanya informing about dun sa investigation na ginawa ng mga specialist ng mitsubishi from Japan related dun sa case ng montero, they conclusion is it is on the driver's error.

This is what is good about mitsubishi, they care for their customers, di sila yung tipong basta nabili mo na yung product nila e bahala ka na.

may no. 4 pa:

owner gets into accident due to his own fault.

wants to claim full value of the vehicle

guilty over negligence and might be laughed at

uses sudden acceleration as an excuse

It's never the owner, usually it's the driver who will never admit he panicked. Or the Septuagenarian father who's been driving for 5 decades and has never been in an accident. Or the brother who's driven a hundred automatic transmission vehicles including a tricycle.

Share ko lang sa inyo yung nangyari sa neighbour ko bali yung sister nya bumili ng brand new Montero GLX wala pang 1 week pinag praktisan nilang magkapatid kasama asawa ng sister to make the story short after yung sister nya nag drive sya naman ang nag drive inasist sya ng sister nakaka ilang ikot na sila sa village scary part of the story bali may mga tao nasa tabi ng isang sasakyan sa right side dahil first time nya mag drive kinabahan sya sa nakaparadang sasakyan at mga tao na mga sales agent ng camella homes instead na brake ang maapakan nya ay yung gas pedal kaya nangyari na the so called sudden accellaration at kinabig nya yung manubela kaya tumawid sila sa island tapos sa opposite lane hanggang maalala nya hindi pala brake inapakan nya kaya nilipat nya paa nya sa brake na halos isang dangkal nalang layo nya sa puno the sad news na trauma sa montero at kararating lang ngayon ng brand new Isuzu bondock pero atleast inamin nya kasalanan nya ang nangyari kaya lang ayaw na nya ng montero kasi naalala daw nya ang nangyari sa kanya at babae din kasi sya at naka eye glasses at first time nya nakahawak ng manubela. Kung minsan buti pa yung mga baguhan ina amin ang pagkakamali nila hindi gaya ng beterano hindi nila kayang amin ang pagkakamali nila at i blame sa sasakyan dahil narin siguro ayaw mapahiya.

im not sure if there is a connection, pero ung mga unang labas ng estrada ay may tendency na mag-"wild" bigla siya magrerev ng napakataas, na hindi mo makontrol (kaya nga wild hehe ). Minsan, bigla nagwild iyong sasakyan habang pababa kaya nahulog sa d naman kataasan na bangin kaya no loss of life resulted. Since then i have been asking the experience ng estrada owners of that model, wala pa ganitong forum then. I was able to confirm na talagang defect nga ng estrada un sa dami ng nagconfirm na they experienced the same at least once. What made me sure na hindi driver error eh dahil may nakaexperience na nagwild ung sasakyan habang naka-idle at nakapark at walang tao sa manibela dahil lumabas iyong driver, it was revving wildly with no apparent reason until it went back by itself to its normal idling state.

so ano ang similarity nung old estrada sa montero? they have a 2.5 4D56 turbo incooler engine, siyempre mas bago montero but is it possible that they are based on the same platform, and if the old problem was not determined then there is that possibility that it was carried over to the engine of the montero.

i know nothing about the montero because im not the owner of one although im interested in one kaya ko hinanap forum na ito when i read in the papers about the issue of sudden acceleration.

Meron pa mga owners ng old estrada, if you know one try asking them...

just want to share...

manual transmission po pala iyong mga old estrada na tinotokoy ko (wala pa yata automatic that time), sa mga nababasa ko ay sa mga automatic transmission nagkakaroon problema iyong sudden acceleration ng montero. my guess... the problem is in the engine, it can happen regardless of what kind of transmission

mitsu007: saan mo ba nakuha mga information and confirmation about Strada? Lumabas ang current generation strada late 2006. 2007 nabuo ang Strada Club of the Philippines. Many Strada owners I know of, haven't experienced this. I for one owned a Strada. Im not ruling out that its a made up story about sudden acceleration, but as most have posted here in this thread, it's probably driver error and don't want to admit it.

I'd like to quote you "I was able to confirm na talagang defect nga ng estrada un sa dami ng nagconfirm na they experienced the same at least once." how did you get these confirmation from Strada owners? If you check the Strada thread or The Strada Club of the Philippines thread, I haven't read of this so called wild acceleration. SCV replacement, that I have heard. I'm really trying to think if I have experienced this uncontrollable acceleration (although I have manual transmission), if ever i have, just pressing the clutch will dissengage the engine from the transmission.

Lastly sir its Strada not estrada.

^ Parang SCV lang na nabara ah. Manual nag-wild? Stuck up cable lang yan! Palitan niyo lang hehehehe :hysterical:

Want to see an interesting statistic in terms of "Sudden Acceleration"?



See that huge spike? That's the months after the "Toyota Sudden Acceleration" incident scare came out, from the policeman who was killed because he couldn't stop his Toyota. (By the way, investigation later showed it was the floormat that held the pedal down)

That's mass hysteria. After the federal investigation was over and hysteria died down, the complaints went back to normal as the ambulance chasers and lawyers lost interest.

From the same article:

SUA complaints per brand, USA, Year-to-Date, August 2011

Brand YTD Share
Ford 3,303 15.9%
Chevrolet 2,820 14.0%
Toyota 2,092 11.2%
Honda 1,157 8.4%
Nissan 1,484 7.3%
Dodge 1,757 5.4%
Hyundai 788 5.0%
Jeep 1,547 3.1%
Volkswagen 581 2.4%
Chrysler 842 1.6%

See a trend? Toyota's complaints trend pretty well with their market share... but ALL manufacturers receive "SUA" complaints.

-

So... is the Montero Sport any more prone to "Sudden Acceleration" than any other vehicle? Not bloody likely. It's just that people now have the term "Sudden Unintended Acceleration" in their vocabulary, and use it to explain incidents like these... whereas before, driver error was recorded as driver error... in the cases of the Everests flipping over or running into Starbucks entrances... or women driving into people while parked.

-

So to change your Montero buying decisions based on a handful of the hundreds of thousands of unintended acceleration complaints recorded every year is a bit silly.

[OTEP]

I'd still buy a Montero if I had the money or wanted to get one. Unintended acceleration allegations have always been a part of the industry. It nearly killed Audi in the 80's. And Kia had it's share in the 90's about a Kia Rio being 'possessed' or something.

Just so happens that Mitsu's market share is really growing. Hence, it will be more sensationalized.

But I never believed in these sudden acceleration thingies.

Check your floor mats. Filipinos really like to pile floor mats on top of one another (natural Filipino trait?). And some add those huge metal pedals that tend to depress the gas pedal even if you intend to step on the brakes.
