Mitsubishi Montero Sudden Acceleration Accidents [MERGED]

[dr. d]

For some people that's not a scientific explanation. Remember, they have the right to know what is going on. They have the right to know if they are in danger, they have the right to know if driving this vehicle incurs liabilities.

Guess a lot of people don't want those rights since they keep on buying Montero Sports. Maybe nobody informed.

Welcome, it's more fun in the Philippines.

in my opinion, there's nothing going on. there is no conspiracy. it's just a case of confused-feet syndrome. the brain doesn't know what is going on, because it's a spinal reflex that doesn't go up to the brain.

I asked my wife's say about this issue. Not a pro but only with her experience driving 3 automatics of different stick styles. A sedan, SUV, and a pick-up. She said, it won't happen unless the driver will make a mistake. A driver's instinct is to hit the brake when the car moves.

This IS exactly the point.

Stepping on the brake and punching the accelerator only shows that you're testing the brake system. That's intellectually defunct as a testing methodology and designed more for PR damage control as opposed to seeking an explanation to things.

The method is to show that if a car's engine is revving hard, the brakes should be able to stop it. And it does.

This is a valid test for the claim that the problem is linked to the electronic accelerator pedal. If the engine is revving because the ECU thinks you're stepping on the pedal... then the brakes will stop the engine.

If the problem is because of some other physical factor, then we don't know.

Forensically, you need to find a factor that will cause both the engine to rev hard and the the brakes to fail.

What can cause brakes to lose power is possibly hydraulic issues (nothing to do with electronics or the engine) or vacuum issues... which can be affected physically by the engine. Now if it's a vacuum issue, you look at all the things that can affect the vacuum system... and those things, if they fail or are on the brink of failure, will show signs of it, or can be made to fail again.

An independent testing body would be a good idea... and if the DTI doesn't do it, who will? The way to move forward with such a case is to lobby for said independent investigation.

Actually, come to think of it... one method might be to try to cause SUA. I can think of one or two ways to do that... and looking on overseas forums, I think some of the symptoms can be replicated.

All mechanical. And it may have something to do with dirty diesel, EGR and SCV. All issues that should leave a physical trace if nobody goes through there and cleans it up after the accident.

-

Of course, the on-off nature of the MS power delivery doesn't help... but it's likely not the main culprit.

-

Again, we won't know until one of the affected consents to sending their car to an independent shop for verification.

Did you ask Hyundai what caused the wild revving of your Sta Fe?

Hyundai marcos diagnosed it as faulty sensor or somthing....may nilinis daw. Mind you its barely 15tkms.

Btt, I agree with niky, no issue with wether the brakes can stop the SUA.

I think issue here is occurrences of sua in montero.

We also had a montero 3.2. Didnt experience that but scary to hear these issue.

Bottomline diesels tend to go wild. Our 4jg2 trooper did, good thing it was my dad driving. The rig has 100tkms on the odo. The monteros im assuming are fairly new...

Another round of Sad Unconvincing Arguments against the MS.

Gusto ata nila ibenta o huwag nang bumili ng MS.

Not really...just saying sh!t happens to modern diesels. Its just a matter of which rig is more sensitive.

Ive seen monteros eatin 180tkms and no problems...the 4m40 that is...

Diesels tend to go wild? I would beg to differ.

Diesels are pretty reliable, durable and economical which is why they're used for public transport and logistics. The earliest diesel car we had was a land cruiser 40 and a W126 and they lasted a long time with minimum issues. I drive a diesel as a daily driver in Manila. I don't think the engine being a diesel is the culprit.

Apologies, I meant modern diesels as we personally experienced it. Trooper crdi, strada 4d56 crdi, and recently our sta fe crdi. I think one of the best ways to prevent this is to ocassionally run it hardon the freeway. Speaking based on experience bro didnt mean to rebut your belief. My 2 cents

Also had a very reliable L200 98 4d56.

Actually they can BUT you have to be a complete ignoramus re maintenance to get there.

Google "diesel runaway". When a turbo oil seal splits it sends oil into the intake. The engine is now using the engine oil as fuel instead of diesel.


If the brakes can hold the car at full throttle then IMO that blows the "nakaapak ako sa preno pero umandar pa rin" SOP reason out of the water.
