Scion xB Engine Problems

  • Supposedly there was a TSB for the computer issue, but I am not sure what the TSB number is. My dealership was very kind in fixing the problem, after the third time and I have not had any issues since. It appears as if there was a problem with a module and very cold weather...

    I have started a class action law suite against Toyota Corp. & Scion Corp. Because all of there cars consume oil, They know about it and when the consumer asks the question they say, "look in your service manual" and there it is in black and white "this car consumes oil' They recommend that you check your oil every time you fill your car up with gas. My car is a 2008 Toyota Scion XB, with 47000 miles on it now and it is consumming about 3 quarts every 5000 miles and the Toyota corp says " it's with in our standards" Which doesn't make any sence in 2010.

    But in your case, please check your oil first! But it could be a simple heat shield or one of the splash shields could be falling off, lord knows how many times those shields have falling off on us. Look under the car see inf there is a shield hanging. I'm a mechanic by trade & Own and opperate my own company. Check out MatthewsRoadService.com
    Keep in touch with us, Oh ya one other thing if you don't know your car is consumming oil , when you have your oil changed ask them to measure the oil that comes out of the engine. The XB takes 4 quarts of oil, 4 quarts go in 4 should come out in a normal running engine. But when the dealer did the last oil change, 1.25 quarts came out, and I put 2 quarts in it a month prior to that change. :(

    Do you check your oil on a regular basis? These cars consume oil on a regular basis, look at your service manual, under oil consumption. I got pretty pissed off when the dealer told me that. So I am collection names, addresses and phone numbers to produce to a lawer to wack toyota with a reality wack! Let me know, Matt

Have you check your oil lately? You should check it every time you fill your car with gas.
    Keep in touch with me, I'll add your complaint to the rest of them. Also check your service manual under engine oil consumption! See what it says, Unfortunatly its not good and its not right. Write your congressman office and complain to them also write a letter to your Attorney Generals office in your state. My letter just went out about two weeks ago. They will responed!

    Contact your local States congressman, all of them! Also write your complaint to your states Attorney General, Lets get the word out about these engine issues, I'll never buy another Toyota or Scion for that matter!
  • I am slightly worried. My 2005 Scion with 160,000 miles on it, didn't start right up as usual today. It coughed sputtered engaged, tried, then died. Started fine on the second crank, however, and ran fine. I just made a quarter mile trip to the store, then back. And yikes, it had heated up badly. Radiator water level fine.

    I'm worried. Any ideas? I'm out of dough. Just had the windshield replaced for $199 cash and the brakes done, badly I might add, at a cheapo shop I shouldnt have used. So I'm out of cash, dead broke and I don't want a dead Scion that's for sure, because I need it to live (get to store, do my job, etc).

    Thoughts on the matter, mechanics out there? I read on the list somewhere, ethanol might be to blame. Well, when they upped the percentage sure did lower my mileage by about two to three mpg. Darn it. But I never have had starting problems ever before. I had it to a shop month and a half ago, to change tran fluid, check everything out. He told me the switch is stuck in the window, the open close the window switch, and he was supposed to order the replacement part but hasn't. Maybe it's draining the battery. But it sounded more like the engine was coughing, not getting enough air or gas, straining, made some wierd little cut short sucking sounds, too. Didn't like hearing that. If I'm driving and hear bad car engine sounds, i turn up the radio, but I hadn't gotten out of the garage yet.
  • I have had that sound periodically too, ever since I got the scion. I have no idea what that's about. I even recorded it once. Doesn't seem to have affected the running of the car, since mine now has 160k miles on it, but it still does it, not that often but usually in reverse. Someone else told me that's normal when the engine isn't warm, or to use lower number engine oil. But, well, I got used to the sound and try to ignore it best I can, when it happens. Nothing bad has happened because of it, in all these years I have driven mine to death. Not that I know of anyhow.

    With 160,000 miles, have you ever changed your thermostat? Don't fool with it, install a new thermostat, Start it in your driveway and carefully watch your temperature gauge. If it gets close to "HOT" cut-off the engine. Aluminum block engines can't stand very much extended temperature. David
  • I agree. Replace the thermostat asap. It's a cheap fix. My 05 has 103k on it with zero issues although my daughter now drives it only 2k a year now. I put 35k/yr on it the 1st 2 years before I found a carpool. One of the best cars I ever owned.

    I know that this is a dead post.. but I could not HELP but correct some inaccuracies!! If you are not correctly informed on what is wrong with your car, then you have no business commenting on it. The 1.5l motor in the early xb's is a variable valve timing motor - like what honda and toyota have been using for many many years. For Toyota is is VVT-i, Honda it is VTEC. Domestic manufacturers are only just now manufacturing 4 cylinders with this technology.

    Basically, the timing is variable, and changes - its dependent on the car's oil pressure. Its ingenious and sounds complicated but works relatively simply. The oil pressure switch communicates the pressure to the variable timing gear (your failed part, in this case) and that gear adjusts the timing for the best performance and/or fuel economy. Its amazing!

    I bought a used 06 scion xb with 40 k miles and had this VVT-i gear fail on me as well. It is a common problem on SOME early - mid 2000 model toyota 4cylinders, and normally fails when the vehicle is within its powertrain warranty coverage. The problem lies when someone ignores their check engine light, or takes it to an inferior mechanic who replaces the wrong parts (like ignition coils? wtf? never had one of those fail on these cars..) and the problem continues, unheeded until it is past warranty coverage. Mine was covered free of charge, on a saturday, by my local 'stealership'.

    Even if you are past your warranty coverage, it is NOT a HUGE job. This car is pretty easy to work on. The VVT-i gear is just one of the timing chain gears. The side cover comes off, you change the gear, (i think it may be on the end of the camshaft?) maintain correct timing, put it back together. voila. Book labor time is 4.8 hours. I have seen much worse cars...

    Every car has a common problem, a slight weakness from factory, and this is the only one I have found on this car so far, It may seem dramatic to some - but trust me, i have seen FAR, FAR worse... I love this car. It is an economy car, sure, but i love, love, LOVE it.. and it has served me very well. It isn't for everyone, though!

    (...I have also personally seen some valve timing issues on the early model honda elements as well...)

    Another note, since I have seen a few other people mentioning coils.. DO YOUR SCHEDULED MAINTENANCE!!!!!!!!! This car needs the spark plugs changed every 30k miles. It is factory equipped with copper resistor plugs and they do not last very long. Do not, by any means, EVER, replace the plugs with platinum or iridium instead. The ignition system is designed to run on a resistor. Your car will run rougher and get less gas mileage with a different composition plug. Also, the stock plug is an NGK v-power copper. I highly recommend!!!

    I am the owner of a 2008 Scion XB.. I am experiencing oil consumption. I took the vehicle to the dealership and they are telling me that because I didn't get oil changes done thru them .. they can't help me with the problem. My vehicle was brand new when I purchased it and I have read thru al the paperwork and there is nothing in the papers that state oil changes have to be done thru the dealership.. They want $5900.00 to replace the short block in car.. How can this fair.. Why doesn't toyota stand behind their vehicles... Maybe a recall since they know this is an issue with these cars... Anyone else have same problem?
  • mrs2010mrs2010 Posts: 7
    It seem like everyone has the same issue of Oil Consumption. I contacted my local Senitor John Kerry, last year. Via by letter, one of his pions called me and said they were going to open up a Federal Investagation on Oil Consumption... Well I guess that never happened is what I found out resently. This is a Federal concern, so I'm going to ask you to call and wright your local senitors and ask them to open up a federal investagation on Oil Consumption! It's not right that we all have to take such serious losses, we took a full loss on our Brand new 2008 Scion XB, biggest piece of crap I have ever bought! Since getting rid of it I have boughten two Chevy van I'm pleased with. I would also contact a local mechanic to do the engine job and buy a used block since they all use oil! That would be the way I would deal with the fix. After the fix get rid of it, trade it sell it what ever! Good luck & please keep me informed, Matthew
  • I have a 2008 XB I am having the same problem with oil consumption …the oil light barley flickered once and luckily I checked the oil and it was 3 quarts low! I can't believe this! I have over 2 years of payments left on this car! This is the worse problem I have had but not the first …last year the air bag harness went bad but was covered under the warranty ..last month the electronic steering went bad but was not and it cost me $750!!! This car truly is a piece of junk and in light of this I will never buy another Toyota product again. This was my second toyota my first was a corolla which lasted 10 years with zero problems and is probably still running somewhere…I sold it as I wanted a new car …big mistake! Everyone having these problems needs to complain about this so maybe they will be recalled and not a total loss…cause I for one cannot afford to just put a new engine in or buy a new car! Please call your Toyota/Scion headquarters to report these problems 1-866-707-2466
  • Yeah well guess what the xb 08 is recalled right now for what……Ignition coils! Cant believe what a piece of crap this car has turned out to be! But the worst of it is the extreme oil consumption. Shame on Toyota. PLEASE everyone call and complain about these cars if you have issues 1-866-453-6667 something must be done!!!
  • I realize this post was a while ago..wondering what came of your problem…I have the following : I have a 2008 XB I am having the same problem with oil consumption …the oil light barley flickered once and luckily I checked the oil and it was 3 quarts low!

  • I also have a 2008 xB, 80K miles :mad: . My oil light is going on now if I don't check every 1500 miles. It's a nightmare. I'll never buy a Scion again.
  • Please call the number in my previous post to complain..if everyone does hopefully it will make a difference.

    Toyota released a TSB for oil consumption on Nov 11, 2011, but it only covers toyota models.

    Hopefully they do the right thing and include Scions which use the same 4cyl 2AZ-FE motor.

    Here's a summary of the TSB (notice they loosened their acceptable standard for oil usage from 1qt/600miles to 1qt/1200miles; still a lot IMO, but hopefully enough to satisfy the owners of cars with excessive oil consumption):

    T-SB-0094-11 on Nov 11th, 2011:

    --------------------------------------------------------------------------

    "Some 2006 – 2011 model year vehicles equipped with the 2AZ-FE engine may exhibit engine oil consumption. The piston assembly has been changed to minimize oil consumption. Use the following repair procedure to address this condition."

    YEAR(S) MODEL(S) ADDITIONAL INFORMATION
    2007 – 2011 Camry HV, Engine(s): 2AZ, VDS(s): BB3EK, BB46K
    2007 – 2009 Camry, Engine(s): 2AZ, VDS(s): BE46K
    2009 Corolla, Engine(s): 2AZ, VDS(s): BE40E
    2009 Matrix, Engine(s): 2AZ, VDS(s): GE40E, KE40E, LE40E
    2006 – 2008 RAV4, Engine(s): 2AZ, VDS(s): BD31V, BD32V, BD33V, BD34V, BD35V, ZD31V, ZD32V, ZD33V, ZD34V, ZD35V
    2007 – 2008 Solara, Engine(s): 2AZ, VDS(s): CE30P

    Inspection Procedure

    NOTE
    In some cases, a P030# (cylinder # misfire detected) DTC may also be set as a result of oil consumption.
    Perform an oil consumption test to determine the consumption rate.
    1. Confirm the engine oil level is full.
    2. Mark the oil dipstick to indicate the current level.
    3. Replace the oil dipstick.
    4. Mark the oil dipstick, oil drain plug, and oil fill cap to prevent/indicate tampering during the test.
    HINT
    Use tape, sealer, cable ties, or equivalent to mark the oil dipstick, oil drain plug, and oil fill cap.
    5. Advise the customer to drive the vehicle normally for 1,200 miles and return for inspection.
    6. Determine the quantity of oil that was consumed in 1,200 miles.
    Was the oil level more than 1 quart low after 1,200 miles of normal driving?

    YES — Go to the Repair Procedure.

    NO — This TSB does NOT apply. Warranty guideline for acceptable oil consumption is 1 quart per 1,200 miles of operation. No warranty claim should be filed.

    I will call the numbers listed above, but won't hold my breath.

    My 2008 xB uses about 1 qt. every 2500 miles and it has been getting worse! If Toyota won't fix this problem owners of the cars affected will take a large hit when trying to sell.

    Stay away from the cars listed in the above TSB and all Scion xb's second generation 2.4 engine.

    Still haven't received my RECALL letter about the bad ignition coils!
  • My XB was in the shop at Toyota when they were trying to make sure it was not leaking oil....when they found that it was not leaking obviously burning it....they told me to call Scion headquarters. I called to tell them of all my problems with this car which started with an airbag problem (was under warranty at time) but would have cost $1,200), then the electronic steering went ($750) , then oil light went on and had next to no oil in it 1,000 miles before next oil change was due! While I was on the phone with Scion they told me of the ignition coil recall so Toyota service department fixed it while my car was still there...that was 3 weeks ago...but I did finally receive that recall letter yesterday 12-14-11. Guess I was one of the first to have that fixed. But that is peanut's next to this oil burning issue.....Toyota made me drive 1,000 miles then measured my oil ...they said it was burning half a quart about every 1,000 miles but said to call scion back to see if they would fix it under this good will thing the repair is 2,700 and basically includes rebuilding the engine! But guess what scion said it is not considered excessive!!! And they will not fix it! I am mortified! How can they sell these cars with out warning people that they will be burning oil at a certain point...it is completely preposterous!!! This is 2011 and it is not normal for new cars to burn oil! So we are now stuck checking oil every week and adding about 2 and a half quarts every 5,000 miles! Give me a freaken break! I cannot believe this and this means war to me! Toyota used to be a great company and make a great car but ...but NO more! I have over 2 years worth of payments on this car! Please call them and voice your complains for as long as it takes if everyone comes forward maybe something will be done! You can also call your local congressmens office , the attorney general, and consumer affairs.....we really need to fight this! I am not rich and cant afford to just run out and buy another car! Shame on Toyota...I will never but another one!
  • 1 quart of oil per 1,200 miles is insane and not normal!!!!!!!!!! This is 2011 for god sakes...how the hell can they get away with this utter [non-permissible content removed]! Shame on Toyota they have went totally down hill...I will never buy another one! My dad still has his 1979 Ford van with 400,000 miles on it and it does not burn that much oil ! Everyone with this problem needs to come forward and complain...make some calls....they cant ignore all of us. Its only a matter of time before someone forgets to add the oil every 1,200and blows their engine ! rrrrrrrrrrrrrrr
  • So what happened with the law suite ??....I am having this problem now and would like to battle Toyota! Cars should not burn oil in this day and age ! Toyota is on CRACK! I am furious!

    I researched the oil consumption on the Internet further and found that Scion did release a TSB at the same time as Toyota. Scion TSB #SB002411 follows exactly word for word as the Toyota TSB (a few posts back) except it list the following Scion models: 07-09 TC and 08-09 xB.

    If you Google "Toyota 2az oil consumption" you'll find several forums (some with 100's of posts) that discuss this issue. Unfortunately, from what I've gleaned from reading through all the posts, Toyota/Scion is sticking to their standard of 1quart burned/1200 miles within their 5yr/60k mile warranty period. Very few will hit this rate below 60k; it seems as though a majority of the higher oil burning engines are over 80k. Maybe if Toyota/Scion gets more pressure it will extend the coverage of this TSB to 7yr/100k (this sounds more fair to me).

    I have about 8 months left until my warranty expires, so I'll be keeping a close eye on my dipstick. My current rate of oil consumption is 1qt/2000mi.

    Hope this helps someone out there. Post any add'l info if found. Thanks

    My 2008 scion XB has 80k and I first noticed the problem around 70k. My solution has been to get my oil changed every 3,000 so I don't have to worry too much about it although I do check the oil every 300 miles another solution I was thinking of was to switch to a heavier oil instead of the recommended 0-20/5-20 I was thinking of switching to 5-30 at my next oil change and to see if that makes a difference. I still say Toyota should do something about this and as you say as more people get higher in miles and come out with this problem....maybe they will be forced to do something! My car also does not get as good gas mileage as it is supposed to. Shame on Toyota this will be my last! Switching to Hyundai they have much better warranties.

    ck'd oil in 08 xb (only 21,000 mi) after seeing this, smelled like gas...had it changed and next day had gas smell again! called service mgr, said its normal...just wondering, if anybody else is ckg theirs, if you touch oil on dipstick does it have gas smell? gotta admit, first time I've ever done it so I really don't know what it's suppose to smell like...and don't really trust Toyota now. TIA. (I change mine/3 mo)
  • isiso11isiso11 Posts: 17
    That is funny about the gas smell because i thought the same thing.....I mentioned it to Toyota during one of my oil changes...they said they did not notice it! I did ask a friend though who knows cars and he said the oil smelled normal so maybe that is how it is supposed to smell or maybe we are on to something here! Gas in the oil would indicate a major engine problem....could it be that all these engines in all of the cars with the same motor are defective!
