The problem
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2010-2016 4Runner, 2003-2006 Tundra, 2003-2013 Corolla, 2009-2010 Corolla Matrix, 2004-2005 RAV4, 2002-2007 Sequoia, 2011-2013 Sienna, 2008-2012 Scion xB, 2008-2009 Lexus IS-F, 2007-2012 Yaris and Lexus ES350, 2010-2017 Lexus GX460, 2002-2010 Lexus SC430, 2006-2012 Lexus IS250 and IS350 and 2010-2015 Lexus IS250C and IS350C vehicles. These vehicles had their driver or passenger frontal air bag inflators previously replaced under a prior recall using inflators of the same design. The inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, temperature and temperature cycling.
The risk
An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
The fix
Toyota will notify owners. Depending on the vehicle model, dealers will replace the front driver inflator, front passenger airbag inflator, the airbag assembly, or the front passenger airbag sub-assembly and inflator. The recall began November 20, 2019. Owners may contact Toyota customer service at 1-888-270-9371 or Lexus customer service at 1-800-255-3987. Toyota's numbers for this recall are J0A, J0B, and J0C. Lexus' numbers for this recall are JLI, JLJ, and JLK.

Brakes

While driving home one day four warning lights lit up: VSC, VSC OFF, ABS & BRAKE, plus a very loud warning tone. I cautiously drove home thinking at any moment my brakes may not stop the car in time. I arrived at home & parked in the garage. I needed some time to think what I should do. I decided to move the car out of the garage. I started it up and began to back out, I applied the brakes to slow down but it did not. I quickly used the parking brake to stop it. The driveway is steep so I decided the best place for...

the car would be back in the garage. Now it just sits there while we figure out what to do with it. I found many others that have had this problem. I am so lucky I wasn't driving on the freeway when this happened. I am sure I would have crashed or crashed into someone else! The brakes should never just go out completely. A disaster waiting to happen.

2003 Lexus sc430. Consumer writes in regards to vehicle sudden acceleration. *Smd the consumer stated as she proceeded to pull out of a parking space, she then place the vehicle in drive, it then accelerated at a high speed. Finally after hitting a pole, it jumped the curb and ended on a busy street. The dealership sent someone out to expect the vehicle. The consumer was provided a disc that showed the vehicle accelerated at a high speed, but they would not say the true cause of the problem, which may have had something to do with the wheel locking and the brakes not functioning.

Wheels & tires

This is an issue involving the apparent failure of three out of four goodyear asymmetric tires. First issue was a bubble found on the outside sidewall of the right front tire. Approximately 1 week later the left front tire let loose a thin very long ribbon of rubber from the inside edge of the tread. A few months later the left rear inner sidewall blew out in two places like a bursting bubble. These tires have the same date code and were put on the car at the same time approximately a year and a half prior to the...

noticed that the left wheel steering arm and lower suspension was cut off from its stem. The knuckle steering was pulled off from the tie rod. The lf wheel was still attached to the wheel shroud and brakes and the lug nuts were intact but it was out under the vehicle. Impact was at the right ft and right fender but the left wheel was cut off at the stem of the suspension arm and steering arm. I looked at the scene of the accident, I noticed excavated markings before the impact proving that metal was scraping on the asphalt road before the impact. There were signs of brake fluid leakage about 15-20 feet before impact. I have pic and video to prove such claim (such as no signs of dent inside the inner housing of the lft wheel, brackets were intact, suspension were intact, brake shroud were intact, lower suspension and steering arm was cut off at the stem). I called your office on april 9 no verbally report this complaint, but your office referred me to lexus. Lexus has been informed at 1-800-255-3987 (option 4 complaint # peter reonisto) and they have agreed to bring the car from the impound into their van nuys dealer office. They have promised to do so on april 14, 2010 but have not yet acted on this complained. I referred this incident with safety research and strategies together with pic and they have advised that nhtsa should be primary in the investigation. I feel that there is valid investigation done [[redacted]]. Information redacted pursuant to the freedom of information act (foia), 5 u.S.C. 552(B)(6). *Tr

The car failed to start six times in the first five months. It seems they have found the cause of that problem. However, the car continues to make clunking noise whenever it goes over a bump. Lexus tells me that is normal. I say it sounds like a 1973 dodge I owned 30 years ago. The car also pulls to the right at low speeds. Again I'm told this is normal and is a result of the run flat tires. If so, they should use other tires. Parking brake light continues to come on intermittently. I have requested that this car be replaced repeatedly. Lexus has refused.

The car veers violently to the left or to the right when braking on a road that is not completely smooth. Depending upon the unevenness in the road, the car will jerk the steering wheel violently either way. We have had the car actually change lanes when braking. Lexus says that this is normal action for this car. If so, there are a lot of people in danger who are driving this model car. This has happened since the car was new. It now has about 3300 miles on it. *Nlm
