Regarding takata recall : hi, I am in need of some help! My 2007 toyota scion has been burning oil often where I am adding oil before oill changes also oil light never turns on even at no oil. My car has been burning over a quart of oil in 1,200 mile from driving it. Now my engine light pops up! Its scary to drive because I feel that at any day if I don't check my oil and it's low, my car will blow up! Toyota needs to fix the problem with the scion cars. I am hoping I can get this fix , I don't have the money to pay for this recall prob that toyota has on this car. Looking for some help and answers. Thanks

My scion tc burns excessive engine oil. Toyota recommend oil change every 5k miles and at about 3-4k miles after an oil change, the oil is burnt so much to the point that when I check engine oil level it's well below the length of the dipstick and red oil low warning light on the dash comes on. This is extremely dangerous, if a car stalls in the middle of the highway due to engine failure with no oil, lives can be lost due to this type of accident. There is already a class action law suite against toyota on this. Instead of a mandatory recall, toyota says you have to do a test first before they're willing to repair for free. I went to dealership for the test and my car burns 0.6qt/1000miles. For the 5000mile oil change interval, my car would have burnt 3qts and keep in mind this engine is designed to hold only 4.5qts. The oil level would be too low to be shown on dipstick. Yet toyota refuse to do the repair claiming that within 1qt/1000mile is normal. Seriously? That would mean by 5k oil change is due the engine would have burnt all oil and bone dry. The federal safety agency, please make toyota pay for this. They are risking people's life just to save money on repair cost. Need help from government in this matter.

For over a year I have noticed that my car has been consuming large amounts of oil. I noticed it when I still had 1,000 miles until my next oil change. My check engine light came on and I immediately went to advance auto parts to check the oil. I needed to put 3 and a half liters in because it was almost completely out. Scion tc's only hold 4 liters of oil. So my car burned up almost all of the oil and I had only driven 2,000 miles since my last oil change!! This is absurd, I bought my car brand new and have kept it serviced regularly and just paid it off! I should not be having this problem, but I've done my research and know that this is not an error on my part for not taking proper care of my car, it is a defect in the engine. I have a friend who services cars at toyota and he said that the engine was built backward and that's why the oil consumption is very large. The only way to fix this is to rebuild the engine. I really am upset by this because like I said earlier I bought this brand new and have it paid off. I should not be having this issue, and since there is a defect in the way the engine was built I would hope that toyota would recall this because it is not up to quality standard plus they need to take ownership of their mistake, and this is a big one that I shouldn't have to go into financial debt over.

On 08/28/2012 I was driving on the freeway on my way home from work when I noticed the radio went out. I exited the freeway. I made it about 2 blocks and was at a stop light when suddenly my car wouldn't advance. A police officer a few cars behind was able to push my car to the side of the road. I had my car towed for service to an independent non-toyota mechanic. I was told I needed a new alternator. Given this was a necessary repair I went ahead and had the repair done. The car was running pretty well until 01/01/2013. On 01/01/2013 I was driving home when I noticed the heater stopped working. Thinking nothing of it, I kept driving. On 01/04/2013 (about 75,000 miles on the vehicle) I was returning from an errand (driving about 35 MPH) when I noticed the check engine light had turned on. I pulled over at a gas station to fill up and called an independent non-toyota mechanic to see if I could bring my car in. I was instructed to bring my car in on 01/05/2013. After I pulled out of the gas station and drove a few blocks I noticed the needle for the thermostat was at the hottest level possible. The next morning I took my car in, it overheated in the 5 minutes it to me to arrive to the shop. I was informed the engine had stripped head bolts and I would need a new engine . I called toyota/scion and they didn't acknowledge either the alternator or stripped head bolts being an issue. The representative, [xxx] said they would open up a case and I was given the following case # 1301070610. I however came across various scion/toyota owners online who have had this issue. A simple google search for "scion stripped head bolts" will show just how many people have this problem. I was told by [xxx] that if in the future scion/toyota recognizes the issue(s) I may receive a reimbursement but there is no guarantee. This is an expensive fix that I just can't afford.

I took a 2006 scion tc in for a mechanic to investigate the cause of a "check engine" warning light. During his test drive, the vehicle reportedly unexpectedly accelerated and raced almost out of control. Per the mechanic, feedback from toyota suggested the incidence was caused by a defective throttle body/sensor. According to the mechanic, the replacement part now offered by toyota reflects significant modifications when compared to the original equipment.
