What Do You All Think? Dealer Service Results

In the states the scheduled inverter coolant change IS later. Read the fine print in the warrant/maintenance booklet.

Also, there may be a sticker on side of inverter coolant reservoir, that confirms a later mileage variable. Our Canadian 2010 has this sticker, I believe it says 160K miles??

Someone should be along to look up those codes.

There's a service every 5K, for one thing or another, not necessarily oil changes. Look up in aforementioned booklet.

 

Your auto service manager will eat well this week, my friend. And next week, too.

Clearing the codes are ok, in my opinion. The misfire may be caused by water in the cylinders or fuel system due to the cold weather. If the codes don't return, and you don't experience missing or knocking in the future, I wouldn't worry too much.

It's a bit of a crap shoot on the type of oil the dealer supplied -- without a test you cannot tell the composition or weight. Yeah, you asked for a specific type/weight. But the dealer may value the margin over keeping a promise. Also, there is no way to check and see if the oil filter was changed. These two issues on the oil change are why I do my own in less time than it takes to drive to any shop in my town.

 

Googling the codes, they indicate cylinder misfire.

To jump from a 5000 service interval sticker, to they've used the wrong oil, is illogical, as Spock would say. They said they used 0W20, take them at their word. Every 5K there's something, if only just a tire rotation.

 

The transaxle fluid needs changing, the container in the engine bay is the inverter coolant fluid, different beasts, time for new brake fluid.
If it was a Toyota dealer they used the correct fluid.
Call and ask how much to change the engine fluid, that was most of your bill.

 

Yeah, they did some diagnostics, and oil and filter change, and an engine coolant change (which requires cracking 2 gallon bottles of the Toyota Coolant): $229 all in is not unreasonable.

What's worrisome is the misfire codes. And wait-and-see is probably as good a course as any. Try to avoid running the engine just for a few seconds when cold, instead let it run long enough to shut itself down. That is one apparent trigger for shaking at subsequent start-up.

 

Have a look at this too:

Like others have said and given background on, the codes are linked to cylinder misfires.

This is a cold start issue, and one you will continue to experience .

One way to eliminate this is to install an oil catch can. Here is a thread about it:

Oil Catch Can, Eliminate that knock!

While a long read, there is useful information .

Seems like you are not the DIY type, but the install does not take much skill, just time and effort. I’m sure some shop could do it for a small fee.

Hope that helps.

 

Great minds type and think alike.

T-SB-0010-12 and others were written to address the knocking on cold start up...much discussed here.

 

When I need to move our (stone-cold) car a few feet, I do it in 10 second spurts, as many as needed, to avoid a start up.

You have somewhere between 12~15 seconds grace after making the car "ready", before the engine starts. I've found you've got basically no chance of EV Mode, with a cold-soaked engine, so I just go straight to the 10 second spurts.

I just wish Toyota had made it 60 seconds.

 

Never got a new manifold for either of mine because they never threw a code...but it didn't fix things anyway. Learned from another member years ago that depressing the accelerator as I'm releasing the start button helps. I think there is an EGR T-SB related to your codes. I'm sure someone will correct or confirm this though. Haven't messed with a catch can personally and probably won't with both my 2010 or 2015...but that's me.

 

If you've had the intake manifold in your hands you get an idea what's going on. The EGR passages can get royally clogged, and the PCV without an oil catch can leaves you with a permanent "swimming pool" directly below the throttle body.

 

Realize you're addressing Engine823, but my experience with TDIs made me very knowledgeable about these two systems and there "problems". My solutions there were less that "legal" though.

 

An easy way to know it they done tire rotation is mark either the front 2 or back 2 tires. I typically write FL and FR with a big sharpie on the designated location of each front tires.

Also take a lot of photos of exterior of the car before taking it in for service. You have to prove that they dinged the car, if that situation ever comes up.

If your beyond crazy, dash cam it and tell them not to touch the device or power source unless you authorized them to do that.

 

I'm paranoid about dealerships and quick oil change places not doing things correctly. Check with you local Prius meetup to get help. They've got the brains of car mechanics and the hearts of teachers.

 

Dealerships won't let you in their shops anymore because of liability. It would be nice to be able to watch them.
I have always done my own maintenance except warranty work but some day I may have to end up trusting them.
Quick change oil places are the worst. I don't use them very often and when I do they usually disappoint me.
I had one oil change done on my 2008 Prius and told them just change the oil. You don't talk to the guy who is actually doing the work so they yank your air filter out and doing all the other stuff they do. I asked to have the oil changed only, they don't communicate and don't get it.
