Serious Engine Knock less than 4000 miles brand new, done with Toyota

And can you imagine him driving on the big, bad beltway in that overgrown golf cart? Yikes.

 

Take a deep breath and calm down bro.

Your car will need a warranty repair no cost to you and Toyota will stand behind you 100%. I know that. They replaced a $1000 door panel I cracked by my own mistakes, no questions asked.

Just go to your dealership and let them repair the car.

I went through a bad cylinder head on a brand new 2006 Suzuki GSX-R600 motorcycle with like 100 miles total - leaking cylinder head, bad casting. Took 5 weeks to get repaired, most of that with bike in my garage, waiting parts. Got through it and rode on.

 

I don't know what yours sounds like, but there shouldn't be any knocking when using correct gasoline.

If you are not satisfied with the advisors answer, next step is to present the case to the manager. If not satisfied, next step is to start a case with Corporate at 800- 331-4331. They will contact the dealer to help resolve the issue.

Good luck.

 

What? Conventional ICE cars do not idle at 4k rpm when first starting up. More like about 1k rpm or so.

So your thinking the motor/generator is the unit knocking? Hmmm.

 

Oh no, I should have read all the posts leading up.

You guys thought I was bad in complaining about this car, shame on you!

 

This is rubbish. The Prius has two motor-generators, not a generator or alternator in the normal automotive sense. MG1 is the smaller one, and can turn at speeds up to 10,000 RPM. MG2 is attached to the drive line, and its speed is proportional to the speed of the wheels. It does nothing when the car is standing still.

Furthermore, the MGs will never knock. There isn't anything in them to knock. They may whine, but not knock.

I don't know where this 700 RPM nonsense came from, but if it really came from the dealer you need to find a better dealer.

1-2 cylinders misfiring due to lean mixture on cold engine?

 

This entire thread has become seriously kooky and funny. I needed my daily laugh

 

How can you say this? You've demonstrated you know very little about automobiles, so this is a tall claim.

They don't. More like 1200 rpm or less.

If the car is still doing it use your video camera next time to start it. I think it's safe to assume that with your neighbors all starting up BMWs, audis, and benzes you probably have the money for a video camera. Post it on youtube and we can see what's what!

LMAO, you have to be the worst Prius owner ever.

I'm back to thinking you are just a troll, to be honest. That's easier to believe than that you're this hopeless.

 

Any why use Premium fuel? Indeed, the 2004-2009 Prius was warned from using Premium as it would cause STARTING PROBLEMS!

Oy

 

Owner's manual says to use 87 octane (regular) gas. Older manuals said to use 88, but that was a misprint. Not to say that using premium is causing your "problem", but why not try a few tankfuls of regular and let us know if the issue persists. At the least, you'll save a couple of nickels...

P.S. - The owner's manual has lots of other good information in it.

 

First of all you should not use premium fuel. The vehicle is designed to run on regular. Remember the link I posted for you to read? One of the possible causes was "Incorrect octane rating of fuel". Well guess what? You are using fuel with an incorrect octane rating. The higher octane could potentially cause an improper firing pattern.

Best case scenario...you're wasting money, so stop using premium fuel.

The idea that the highest octane is the best fuel is an old wives tale. Why don't you put jet fuel in the car? REAL high octane. Wanna see it knock then? Yikes.

I agree with Skoorbmax, you definitely don't have anywhere near the knowledge or experience to make a claim like that. If you don't know what a lean fuel mixture is, your assessments of vehicle problems are about as valuable as your assessments on brain chemistry. Knocking can sound scary, but usually will not cause damage, especially an isolated incident like this.

I would start using the correct fuel for the vehicle, and see if it happens again. If it does, take it to another dealer. If not, and I suspect it never will...just get on with your life and chock it up to a little hiccup in the fuel system or using the wrong fuel.

Of course they don't, nor does the car sound like a "Thomas Edison Generator", You had an isolated incident of knocking that has gone away. Let us know if it comes back.

For the record, if you wanted a vehicle that was as smooth and refined as your neighbors expensive German luxury cars...you should have bought an expensive German luxury car, not an economy car that cost less than half as much...

If your neighbors put the wrong octane fuel in their Audis, BMWs & Benzes you should hear how they would knock at startup.

Don't be so dramatic.

 

My Prius hasn't made that sound yet but I wouldn't be embarassed if it did, I know I'll be getting 20 or 30MPG better than they will.

 

You do not need premium, 91 pump octane fuel in any Prius, they run fine on 87. Higher octane fuel is simply to prevent pre-ignition or knocking in higher compression engines and turbocharged cars.

Prius' is most certainly not a high performance engine FE's a 10 though

Ok, 2 bars, you had plenty of fuel in the car.

What dealer did you take your car to for repairs? Where are they?

 

I've noticed that on each Friday, when my front right (passenger) tire goes over a pothole, there is a "thump", and the car shudders slightly (not the braking issue discussed her so often). It seems repeatable - but doesn't occur on general commutes on freeways.

Haven't tried it other days of the week - but guess I can give it a whirl in the interest of science...

Edit: Forgot to add - if I keep going straight, the thump seems to happen again - just after the first one

 

Not your typical economy car though. Quite an upscale one.
