Five problems related to engine burning oil have been reported for the 2008 Toyota Scion Xb.
1. Incident the driver was driving the 2008 Scion Xb alone on east-bound I-80, approaching carquinez bridge, vallejo, when the vehicle stopped working. The driving speed was about 70 mph. Time of the incident was around 12:45 a. M. On December 25, 2014. He was driving on the 1st lane, and to the best of his knowledge, there was only one compact car passing nearby, when the car stopped all of a sudden . He tried to reach out for a tow truck without success, but later on he remembered he was an associate member of a classic membership card registered in the name of his mother. But he did not have the card on him at that time, but gave his name to aaa to prove he is an associate member. Finally, the aaa tow truck arrived on the scene around 1:45 a. M. He towed it to home, and days later had it towed to a mechanic shop, east bay auto located on north texas street. The mechanic diagnosed the problem and said the engine got broken and the car needed replacement of the engine. 2. Scion side on Feb. 10, 2015, the owner of the vehicle received a letter of warranty enhancement notification from scion. The owner did not take an initiative to call scion before receiving this notification. The next day, the vehicle owner called scion and filed a claim for engine failure due to excessive engine oil consumption. Case #1502112113. The customer service rep at scion arranged for Toyota dealership in vacaville to inspect and diagnose Scion Xb to see if the engine failure was due to excessive engine oil consumption.
My vehicle is consuming an excessive amount of oil. This issue started at roughly 58k. I have never been low on oil at any oil change. I was approximately 3qts low at 58k with no signs, at all of an oil leak. I took my car to Toyota where an oil consumption test was performed. I was then informed that my engine is having the oil consumption problem as listed in a TSB issued by Toyota on August 11, 2011. Because my car is no longer under the power train warranty, Toyota is refusing to cover the costly repairs.
Engine locked. My car was diagnosed with "oil starvation", which was due to scion's "oil consumption" problem. Because I did not have my oil changes done at the dealership, they found a loop hole to avoid paying for a new engine. There has been a TSB issued on this problem and scion refused to take responsibility.
Extremely excessive oil consumption. The vehicle uses over 3 quarts of oil between oil changes (5000 mile oil change interval. ) we are concerned that the engine may seize while driving, due to lack of oil, causing a crash. (Toyota issued a TSB regarding this issue in 2011, due to a design defect. ).
After around 50k miles, I noticed that the engine oil was about a quart low when taking it in for an oil change. At the time I was told pretty much what the owners manual states about oil consumption. I've owned many vehicles in the past, old and new, and never had one that used this much oil. If any of them did use oil, it was a small enough amount that you can't tell from the dipstick. So, with their explanation I moved on. As time went on, it seemed more and more oil was being used by the engine. Now after the warranty would no longer cover such a thing, I was told that I could bring the vehicle in for an oil consumption test, which I did not do since any problem they discover would come out of my pocket. As time progresses, the vehicle is at the point where I have to check the oil every week and add oil. I learned that if I wait for the next oil change @ 3000 miles, there is no oil left in the engine. What's even more disturbing is that there is no indication on the instrument cluster that anything is wrong. I would suspect the oil light would come on at some point, but never have I seen this light, or any other light come on indicating an issue. To sum it up, there are no leaks, the engine will consume all of the oil within 3000 miles if not monitored, and there are no warning lights indicating a problem.
