Thank you for this! I provided the VIN and the site says there is no recall or service campaigns for this vehicle. Bummed!
When I enter my VIN it doesn't say there are any available recalls or anything either. I drive a scion tC and I just had the warranty work performed after a failed oil consumption test, I would say keep trying.

I have my 2008 Scion XB fixed for the Oil Consumption issue, and like Marsha, the first day I drove the car out from the dealer it sounds like it has muffler noise from the engine area. It sounds like I have a racing header installed. I continue to drive the car for about 3000 miles now and the noise indeed is getting lower, but not completely gone yet. Anyone else has this same "muffler" like noise after the Oil Consumption fix?
I am having the same experience with what I believe is the same noise. I had to return the car after 5 miles leaving the dealership because of loose bolts that were making a rattling sound. My engine however does sound different. It sounds a little more aggressive and sometimes there is a faint whining sound or high pitched buzz(its pretty annoying). I followed the correct "break-in" procedure, I am at around 1000-2000 miles, the sound has reduced a little bit, but it doesn't sound the way it did before the fix. Does anyone know if this is normal?[/

You can also ask your Dealer. the next time you are in for service, to print this out for you. Their records may be more up to date than that website.

I am eligible for the rav 4 excessive oil use warranty enhancement (failed the combustion test). When the part is available, what else should i replace during the engine fix?

Have you taken it back to the Dealer and had it checked?
I did and they said nothing wrong with the car (no check engine) and they could not hear what I claim to be louder. I am going back to the dealer this Sat morning. The issue here is I don't know if louder than usual after the oil consumption fix is the new normal? Where do I have to check if any leak, loose bolt, etc?

Mine was the same when I drove off from the dealer lot after the fix .. I was like "oh my .. did they replace my engine with a V8 block?" .. I didn't get a chance to take it back to dealer right away and now is about 3000 miles (after the fix) and the engine is less louder, but it's annoying like having an extra muffler at the front of the car (noticeable around 2500 - 3000 rpm).

That is a great question. The person you should really ask (work with) is the technician working on your vehicle. All you have to do is stop in and ask to speak with him/her. They will love you for that. Just for basics I would have the head sent out and reworked with valves stem seals put in and the valves shimmed. New plugs, drive belt, water pump, thermostat, fuel injectors and air filter if needed, all these items will be at cost of the part only as they have to put either the old or new ones back on anyway. These are just a few of the things off the top of my head. The rest of the items like new seals will be taken care of during the rebuild.

I don't think I can talk with the mechanic directly (they are at the back & usually don't interact with the customer). So usually I only talk to the service advisors (the front desk type of person who write our repair order) and the mechanic will be assigned later base on their availability. Anyhow, the service advisor offered me to meet with the master mechanic this Sat (tomorrow morning). I hope he can hear what I am talking about and he will call it as not the new normal.

Hi everyone,

I recently got a 2007 Camry with less than 70k on it. I have the habit to open the hood every week end and check the levels. I noticed that the engine oil keeps going down regularly to the point I had to add oil to it. I took it to the deal (Toyota team PA). They offered to run the test. I was told that I can check the oil level during test. So they did the oil change. The following week end as usual I check the oil level and I was surprised!! They filled up 1/3 of an inch over the maximum level! I immediately took it back to them. They were not happy and told me that the oil level is where it should be and informed me that I’m not allowed to check the oil until the test is over. When almost 1300miles are over, I took it back to them. I waited a little bit then the customer service guy came to me to tell me that my car doesn’t consume any oil and it’s very clean…! Really! He said that I can do another test. Once at home, I found out that they added oil to it to much the maximum marking. Now, there are two explanations to this one of should be correct. The first one, it’s a bad dealer with no ethics. Or Toyota wants it to be this way to save the repair cost. I’m very disappointed by this experience. Toyota is known to be one of the best brands but I don’t think so anymore. I was thinking about buying a 2015 Camry. But it will not happen after this. I will run the second test and will keep you posted.

Yes, yes they do and yes you can. All you should have to do is ask. I have seen this done for a test drove many times.
I hope he can hear what I am talking about and he will call it as not the new normal.
Simply ask to take a test drive with the Master Tech to show them what your concern is. They "usually" don't bite. :eek:

This is not true and why temper proof stickers are put of the oil cap, dipstick, drain plug and oil filter. That way we get a true, unaltered measurement of how much oil the engine is burning. Here is what they look like...

informed me that I’m not allowed to check the oil until the test is over.
Yes, this is correct. You are not allowed to tamper with the test.

Now, there are two explanations to this one of should be correct. The first one, it’s a bad dealer with no ethics. Or Toyota wants it to be this way to save the repair cost.
The third and fourth explanation I can think of is that you added oil just to confront the Dealer or you're lying about this whole ordeal. Now I know you want to get right behind the computer keyboard and show me what's what but just take a step back and think about this.
If someone told you that you can check the oil level while the test is being conducted, what sense does that make? If the oil consumption test is not a sealed test then anyone can add or subtract oil from the engine rendering the test invalid. There is a procedure that must be followed and a check sheet that gets filled out and signed by the technician conducting the test.

You will have to wait 6 months or 5,000 miles to have another test performed. When they perform it this time, simply ask to be there when they add the correct amount of oil and then watch them seal the engine. It's your car and I cant see why anyone would object to this. It does give a feeling of distrust but whatever, it's your car.

I will run the second test and will keep you posted.
Please do. I look forward to seeing the test performed properly.

So I got the chance to sit down with the Master Tech and he heard the extra muffler sound. He told me that he triple check all the nuts and bolt on my car to make sure everything is good. For now, he suggested for me to drive it until the next oil change and see if the sound is still there (since it seems to get less from the time I drove off after the fix).

The Primary Coverage offers warranty enhancement until October 31, 2016 regardless of mileage.

The Secondary Coverage is applicable for 10 years from the (DOFU) Date Of First Use or 150,000 miles, whichever occurs first.
First - I'd like to say a really big thanks to all of you for what you are doing with this message board. It is a really great resource because of you, and I really appreciate it! Now, on to the messy stuff.

So am I the only one who wants to know the difference between Primary Coverage and Secondary Coverage?

I've had my 2009 Camry in for it's first oil consumption test, and it burned "only" about 3/4 qt in 1200 miles. The letter I got says I have primary coverage through October 31, 2016. I bought the car new on Dec 31, 2008, and it only has 66k miles, so at my current rate of use, the second test if done before the end of the primary coverage, still probably won't show the required 1 qt in 1200 miles.

The letter says to contact the local Toyota dealer for additional details, but they couldn't really give me any information.

So what's the secondary coverage? Anybody got a clue?

My 2008 Camry(135K) failed the oil consumption test. I'm taking my car in to the dealership in a couple days.
What other maintenance repairs should I have done while the engine is being repaired. I'm assuming the plugs and the belts should be replaced with new. Since the labor is free, what else should I have done. When I get the call from the service advisor what else do they typically recommend?

This is done so that initially EVERY vehicle gets coverage. Please keep in mind that vehicles covered date back to 2007 model year and this program started 2015-ish. :rolleyes: So many if these covered vehicles are 8-9 years old and have way more than 150,000 miles. This Primary coverage will allow everyone to take advantage of this program.

The Secondary Coverage is applicable for 10 years from the (DOFU) Date Of First Use or 150,000 miles, whichever occurs first.

The Secondary coverage is to cover everyone else who didn't need to come in right away due to age or mileage limitations and gives them time. That way if their vehicle hasn't been driven enough to exhibit oil consumption issues then they have more time and miles to see if the concern does arise. It also doesn't leave Toyota open ended to repair vehicles with 20-30 years and 500,000 miles on them.

I think right now the highest mileage I've seen repaired is 300,000 miles.

Hey guys - Thanks for the forum! This forum got me started on my case with Toyota which has finally concluded after 4 months. As frustrating as it was throughout the process (they make it as difficult as possible so you want to give up) they finally made things right and I received full reimbursement for the replacement engine that I had to put in (overheating engine failure) in addition to receiving a new engine block (to replace the one I had put in because it also had the oil problem...) to fix the oil consumption.

Helpful tips I will share.

1) To receive reimbursement for prior engine work as a result of the excessive oil consumption, you need to have all your documents. This includes proof you have been maintaining your vehicle (oil changes), work done (misc repairs), receipt of transaction (oil related problem), quote for that work, and most IMPORTANTLY - the CCR statement. This statement discloses the problem, root cause, and solution. You might need to go back and ask your mechanic for this writeup on the work (I had to do this). It is imperative that low oil/excessive oil consumption is the root cause that set off a chain of events and failures. To receive reimbursement, the problem has to be related to the oil and it has to be clearly stated.

2) Save your oil receipts!!! You will be reimbursed. I had not been keeping them, but I was able to provide them an estimate of how much oil I burned using my proven oil consumption rate by Toyota and yearly miles to calculate an approximate quart total. They accepted this.

3) Fail the oil consumption test. Don't waste your time unless you burn more than a quart of oil per thousand miles. My oil consumption test was 200 miles per quart... I could not even come close to making it to the 1k miles as stated by the test or another engine would have been destroyed. One thing that always bothers me with Toyota personnel is how they always downplay everything and make it sound like no big deal. The service rep told me I burned a little over a quart in 300 miles. A little over? It was a quart and a half...

4) After all of that, be patient, be polite, and most importantly be persistent. There is a huge back log of cars waiting to get fixed. How Toyota could have designed an engine this poorly is beyond me. I thought that's what testing on the DYNO's was for...

Whatever you do, don't give up. If you are missing documents, find those. If they say they can't do the work to your engine because it's not the original (had to be replaced due to failure), move it up the ladder.

+Someone mentioned that whiney engine sound - My Rav4 also makes that sound pre fix and post fix - Don't be alarmed.
+Muffler sound could possibly signify something is up with the CAT. Burnt oil and poor combustion is bad for CATS.
+My Rav has significant more power due to the compression issue being fixed. So nice to not always see it hit 3k rpm for basic acceleration. AND finally not burned at every intersection.

I will conclude by saying thanks Toyota for following through and thanks to those of you in this forum.

Best of Luck.

Hi, newbie here
I have a 2006 rav4. 9/2014 my oil light went off so I went and had my oil done right away. The tech said there wasn't much oil in the engine but made it seem like it was no big deal.

In between there I had a few oil changes and no one ever mentioned the oil being low.

About a month ago when I was turning a corner, my oil light went off. When I checked it, nothing showed up on the dipstick. This totally freaked me out. I added oil and kept and eye on things.

I got the notice for the extended warranty and needed an oil change so I went to the dealership and they are running the test.

My questions are: 1. Why was the oil so low when the oil light went off? And that was only when I turned a corner. It wasn't on during normal driving. Shouldn't the oil light go off before that?

2. I don't know much about cars. During this test, will there be any signs that my oil is too low since I can't check it? And since the oil light doesn't go on until it's too late?I don't want to ruin my engine.

3. If my car passes, and I go in for a recheck in six months, should I watch them do the test? Just to see how much oil they put in and how much is left when I bring it back in? I'm normally a pretty trusting person but this test is a big deal as far as $$$ and I want to make sure it's done fairly.

4. Are you required to have an oil change when the test is started?

Thank you

The oil light coming on is only based on oil pressure. When the oil pressure gets low, then the light comes on. yes, this could be because the oil level is low but that not the only cause of why the light can come on.

2. I don't know much about cars. During this test, will there be any signs that my oil is too low since I can't check it? And since the oil light doesn't go on until it's too late?I don't want to ruin my engine.
No, the only indication will be the oil light and if you see it come on, return to the dealer immediately. Don't wait for the mileage of the test to finish.

3. If my car passes, and I go in for a recheck in six months, should I watch them do the test? Just to see how much oil they put in and how much is left when I bring it back in? I'm normally a pretty trusting person but this test is a big deal as far as $$$ and I want to make sure it's done fairly.
You can watch them perform the test and all you have to do is ask. After all, it is your car. Don't worry about trust or what they might think of you. Most Toyota Dealer Service departments are very accommodating to customer requests like this.

4. Are you required to have an oil change when the test is started?
No.
