The contact owns a 2007 Toyota Avalon. The contact stated that while driving at approximately 25 mph, there was an abnormal odor coming from the engine. The contact then discovered that there was oil leaking from the engine. The vehicle was towed to an independent mechanic where it was diagnosed that the oil line hose had fractured. The vehicle was repaired. The manufacturer was notified of the failure. The approximate failure mileage was 101,000.

When driving North on I-95, my car began to slow down even though I had not released pressure on the gas peddle, so I accelerated. As soon as I accelerated, the car then began to run extremely rough, the RPM monitor fluctuated back and forth, and the began to slow down even more. I looked in the rear view mirror to check traffic as I prepared to pull off the interstate and saw smoke coming from the rear of the car. When I stopped and exited the car, smoke was then bellowing profusely from the front right side of the hood and upper right tire rim, so much so that I thought the engine was about to explode. It should also be noted that the check engine light never came on. A tow truck was called and now I'm waiting for my local Toyota dealership to open so that I can find out what is wrong with my car. A similar energy surge and rough driving occurred approximately one year ago and my car was towed in, but no problem could be detected. The problem stopped as mysteriously as it appeared, with no serious reoccurrences until yesterday, 9/7/15. In 2014, the mechanic chalked the problem up to possibly bad or cheap gas.

Collision with another vehicle while making a left turn. Driver's upper and lower (knee) airbags deployed. Driver incurred severe cuts to both legs below the knee approximately half way down to ankle. Cause of injuries has not been determined but inspection of vehicle disclosed that the knee airbag containment compartment in the low part of the dash has a flap/door that opens in deployment, is very extremely sharp and may have been the source of the injuries.

The radio station started to fade in and out. Then the dashboard console started to shut down and displayed the letter F (for fail). Then the engine shut down while I was driving on a divided four-lane highway in the lane closest to the median. There was no time to move into the right-hand lane. There was never any battery warning light or other indication that the battery did not have enough charge to run the engine or even to power the emergency flashers. The problem was that the alternator failed. The battery didn't need replacing. Only the alternator needed replacing. I had the Toyota service department test the battery warning light and was told that the sensor was working properly. I have had no trouble with the car since the alternator was replaced. I was told that the alternator has three diodes and the failure of one or two diodes can still provide sufficient charge. Evidently eventually all three diodes failed. I wasn't told how many failed. My complaint is that I had insufficient warning that the alternator had failed. As far as I knew, the problem was in the console which I thought would not require immediate exit from the four lane highway. The lack of a proper warning means to me that I could have been stranded on an interstate expressway without a means for getting out of a high speed lane. That is a very dangerous situation and warrants an investigation into why Toyota provides no warning for an alternator failure.

The variable valve timing oil feedline was a recall for Toyota a little short time ago in, 2015 the same problem reoccurs and I was just told by Toyota that this is not their problem it's my problem I felt to understand how a factory defect would be the consumers problem

Upon traveling through nash, tx on November 5, 2013, the oil light on my 2007 Toyota Avalon came on. The leaking line over the right front wheel busted. I pulled into robbins Toyota. I spoke with service consultant [xxx]. he asked me what the problem was and I stated my oil light came on and I was experiencing an oil leak. He said he knew what is was and got my information and how I was going to pay. I told him cash, credit, or check. Then he asked where I was from. I told him Georgia. He said he had the part to fix it and I asked [xxx] how much it would cost me? he replied $400. I said that sounds like a lot for a 6 inch hose. He stated I could have it fixed somewhere else but they had the part in stock. I said you know I cant drive this car like this so go ahead and fix it. They fixed it but only charged me $339. I was there for two hours and they charged me with two and a half hours. According to Toyota it should take less than an hour. I received a letter from Toyota on November 29, 2014 that this part on my 2007 year model Toyota had been recalled. The letter stated if the part had not been replaced make an appointment to have it replaced by December 31, 2021. I sent all the information the letter stated and was sent a letter back saying I was declined for not sending everything that was asked. On January 8, 2015, I contacted my local dealership and he sent over all the information again and explained to them that I traded the car in June 2014. My case number is 1412170721. We never heard back on my case as of March 24, 2015. The letters received were from Toyota motor sales, U.S.a., Inc. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Leaking timing cover. Service manager at jay wolfe Toyota, mo., say that 20% of Avalons have this leak and will cost me $2,464 to repair. I mentioned that I worked for Ford Motor Co and sat in on the weekly safety office recall meetings. He replied, 'it's not a safety issue', I said that if 20% vehicles have a failure rate after 7 years, NHTSA would like to be made aware of problem.

My 2007 Avalon never had an oil problem. Last Thursday I noticed oil in the driveway as a shoveled snow. I checked the oil level and the vehicle was 1 1/2 quarts down. I put the 1 1/2 quarts into the car and drove it to my mechanic 5 miles away. The mechanic said that the vehicle was totally out of oil and that I was very lucky that the engine didn't catch on fire because the oil was spraying all over the engine. The mechanic diagnosed the problem as an oil leak from the vvt-I oil hose. I went on line and discovered this limited service campaign for vvt-I oil line. I contacted the dealership where I purchased the vehicle. They stated that they would get back to me. They never did. I contacted Toyota.com and spoke to the representative. They stated that the lsc was for 07 Toyota Avalon's but my VIN wasn't include in the lsc, even though it was the same problem all the 07 Avalons were having. This problem is going to cause major damage to the Avalons. It is also very dangerous the way the oil leaks all over the engine. There is going to be a large number of engine fires. Toyota basically told me to bad and good luck. I hope something will be done before someone gets badly hurt. Obviously all 07 Avalons are effected not just a certain few vins the lsc can be obtained by goggling vvt-I oil leak, 2007 avolonshere is the lsc.

I was driving my 2007 Toyota Avalon on 3/23/13 when the check engine light, traction control light, and stability control light all came on. I immediately went to a local Napa store and discussed the error/S (found on my vehicle dash) with one of the sales assistants.. the sales assistant then went out to my car and interfaced his "black box" with my automobile computer and an error code P 2197 showed up. As it turns out this error code is a faulty oxygen sensor in bank two of my right exhaust manifold. The Napa store did not have the oxygen sensor in stock however, as a favor to me they reset the computer and I regained use of my traction control, stability control, and elimination of the check engine light. After further research and verification from an independent garage it appears that Toyota has a technical service bulletin on this issue. The technical bulletin is T-sb-0114-08. It applies to 2005-2007 Avalon's and 2007-2008 Camry's. the tsb states that the corrective action should include replacing both exhaust manifold oxygen sensors as well as the right exhaust manifold and gaskets to the tune of approximately $1,800. This is quite evidently an emission issue impacting the safety (no traction control and no stability control) of passengers in the aforementioned vehicles. It is also quite evident that this defective design puts the repair cost right on the back of the consumer. Who has ever heard of replacing an exhaust manifold.

Avalon 6-cyl

I was parking my car in reverse at a speed of less than 5 miles in a designated spot adjacent to my daughter's house in quebec, Canada. The engine accelerated and hit a wooden fence behind my car. I applied the brake and put it into drive to go forward and to get out of the car to see what happened. Then, the car sped at about 100 miles an hour and crashed into a metal fence of a kindergarten school across the street and hit a tree inside the kindergarten. Then again, the vehicle crashed into the brick wall of my daughter's house in reverse. A 2X2 concrete block from the brick wall that my car encountered hit my rear windshield and landed inches away from my head inside my car. I called 911 and police showed up and they towed the car and I realized it was 9:41 pm as confirmed by the time on my cellphone and luckily no children were there to get killed.
