I am writing with concern to see if the recall on my daughters 2003 toyota air bag issue was truly fixed, she was involved in a traffic accident where according to everyone's opinion the airbags should have went off however they did not. Is there any way to see if the recall work was actually done by the company who states they did the repair ??

P0446- evaporate system vent control circuit I was driving normally like any other day when I noticed the "check engine light" turned on. I went to a mechanic they told me that the vapor canistor had an issue but that, thats completely the car manufactures problem because the part# vc4079 is under lifetime warranty so it shouldn't be damaged.

Takata recall I have submitted papers of numerous accidents and also engine and transmission failures my vehicle has given me. When I first obtained it, it had no struts nor do my air bags deploy when I get into vehicular accidents. I am unable to go to a dealership and get my vehicle checked but because it's non operating at the moment. I do however have open availability for a car inspection at my home if you guys were to send someone to come take a look at it.

I was driving at a track event and my engine started to knock, my oil pressure light came on. I drove it back to my parking spot, loaded it on a friends trailer and got it home. I checked and topped off my oil before leaving but we found out it was due to oil starvation.

Catalytic converter failed and replaced by dealership under service campaign at 69,811 miles has now failed again at 152,000 miles. Toyota notified at they declined to provide repair again at there expense. I had a honda go 250,000 and never have a problem with the converter. There has to be an inherent problem in the one in my toyota corolla !! Also other recall on airbags they do not have parts to fix.

In 9/2007 the transmission and clutch went out on my manual 2003 corolla. Conveniently, it was beyond the warranty period. I spent a significant amount of $ repairing. Again, in march 2015 the transmission and clutch are going out on my manual vehicle. After researching, I found numerous owners experiencing the same problems. There is a serious defect in the 2003 manual corolla that was apparently fixed in the 2004 version. I have contacted toyota several times. They will do nothing. They told me to email...

I experienced a stuck accelerator pedal in my 2003 corolla.I tried to kick the pedal loose and could not.I ended up grabbing the key and shutting the engine down to avoid losing control on the snow covered road and hitting traffic in front of me.I later determined that the throttle linkage had lost normal freedom of movement in the cold weather,even though I had cleaned the inside of the throttle body some months earlier.I believe most people would have had an accident in my situation.The only thing that saved me from an accident was my mechanical knowledge of cars enabling me to make the right decisions to avoid an accident. *Tr

repair company, allstate insurance, and toyota of orange were denied although vehicle was not operating properly. Example brakes never worked, and locked and skidded at 2-5 miles per hour which was extremely dangerous on road. In may, I took vehicle for smog test and was informed vehicle would not pass visual inspection test due to non approved after market parts on vehicle not related to toyota. At this time specifically catalytic converter is not an approved part. Only toyota dealership worked on this vehicle until 2012 when visit to arizona. No one will help me regarding this matter, and I cannot get tags and registration. I am disabled and immediately need my vehicle. Can you please assist me in this matter as not only is vehicle unsafe, but I have no recourse and no place to turn. *Js

This is a very dangerous issue. Car engine randomly shuts off while driving. Check engine light will not go off. I cannot drive car because I cant pass smog either (due to check engine light). I have filed two formal complaints with toyota. Toyota refuses to take responsibility for the manufacturing. Defect. I am expected to pay over $2000 to replace a catalytic converter that they know is defective.

to 2008 model year corolla's and matrixes, equipped with the 1zz-fe engine and two-wheel drive. The recall notices states that an improperly manufactured engine control module (ecm) can develop a crack in its circuitry, potentially causing the "check engine" light to illuminate, harsh shifting, and stalling and/or failure of the engine to start. I have a 2003 matrix xrs with a 2zz-ge engine with a continuous check engine light, harsh shifting, stalling and random failure of the engine to start. I have had multiple diagnostics and repairs done on the vehicle to pass smog inspection over the past 5 or 6 year and have spent thousands of dollars. The light stays off just long enough to pass the smog test and is then returned to me with the light still on. I have paid a toyota dealer $95 to run diagnostic also. They said the ecm is corrupt and can't be flashed and the cat has to be replaced for over 2k! I would like information from you're quality department as to why toyota will not replace the ecm being replaced on the engines stated in your recall notice and not on my type of engine. Which has the exact same problem as detailed in the recall listed on your site. Toyota stated after both complaints that they cannot help me or fix the problem. I must pay for solution myself. Does someone need to die in a crash before this is addressed? *Jb

It's been almost a year since the first time the cil turned on. It stays on for a couple days then stays off for like a month. It has been doing that since 2012. I had my check engine light checked by a tech and he said that he has seen the p0770 code many times for the matrix and corolla. He printed out the tsb (http://www.Matrixowners.Com/tsb/t-eg020-02.Pdf) and advised me to take it to a toyota service center. I took it to carson toyota in ca and they pretty much said the only thing I can do is fix the issue out...

of my pocket which was almost $1500! He said the issue is the r & r engine control module and if that doesn't do the trick that I have to replace r & r speed sensor. I purchased my car used so it didn't qualify for the manufactures warranty. I personally think that this should qualify as a recall. There is so many report about this issue and so many other toyota customers that are very unhappy. Allot of the consumers are saying they have bought these parts and installed them and the cil is still lighting up. I would really like to resolve this issue. I refuse to pay $1500 to replace the ecm and the speed sensor for it to not fix the problem. Now I have to have my car registered with the requirement of a smog check. And of course that is an automatic fail. This is my second toyota and I don't think there will be a third. Very unhappy customer! *Tr

I was driving home from work when the transmission locked up. I pulled over turned the car off and back on. I managed to put the car in first gear and make it back home even though the transmission was making this loud grinding noise. I brought the car for repair and they tell me I need a new transmission. Just 6 weeks ago I had the clutch replaced. After investigating this issue I have learned this is a very common problem. Something must be done about this. *Tr

I was driving the car, a toyota corolla 2003 on july 12 and while driving it turn on the check engine light, next morning while driving the car in a highway the car turn off. I didn't have an accident because it was too early in the morning, after couple attempts the car turned on, I call a toyota place, where I do all maintenance of my cars, and after I called I went there so they can run a test. The result was shift solenoid "e" malfunction. The worker told me that most likely the problem is the computer, that there was a recall but on the corolla 2006 not 2003. Hopefully you can help me with this. He told me to file a complain so I don't know where. *Tr

The agent stated that my gas cap may not be tight enough. I tightened my gas cap and the light when off for about 20 minutes. It never caused any problems in the performance of the car. However, when I went to get it smogged for the first time, it would not pass smog. The mechanic at the toyota dealership stated that it...

needed a catalytic converter and that it would cost around $1,800 to replace. Therefore, I had to go the referee to get a 2 year waiver on my smog. I am a single mom with 2 special needs kids, I cannot go without a car. My car will be going on the next year soon. I would like to know if there is any funding to help with repairs when the problem is due to manufacturing defects. I know that this is a factory issue because I have read many complaints from other toyota customers who have had the same exact problem with the same model year car. *Tr
