Repeatedly this car is doing dangerous, bizarre things, and they're getting worse. There' is apparently a problem with the electrical system: when honking the horn the radio comes blaring on very loud and the AC and blower blast out at full force (startling my daughter); sometimes when braking hard, the radio goes on; often when honking the horn, the AC goes on and the radio goes on; when using turn signals the AC goes on and the heater goes on; when turning on AC the horn honks. This is more than annoying -- it is bordering on causing possible serious distractions and an accident. This is a toyota problem -- why should I have spend big dollars getting it taken care of. Surely other car owners have reported similar issues???

Many very annoying and potentially hazardous electrical glitches (but which are very hard to replicate, and new glitches can appear without warning). Some examples: when I honk horn the radio might turn itself on; honk horn while braking and A/C may decide to blast on full force; use right turn signal and radio may turn itself on; doors two times unexpectedly locked when everyone was out of car for a moment (could be dangerous if car is still running or keys or a strapped-into-a-carseat child is left inside!); also, heater will not maintain constant temperature -- far from it, resulting in constantly jiggering the temp up dramatically, then down dramatically to make the temperature reasonably comfortable. All above, except for when car locked everyone out, happened while car was moving, in city and rural driving. Recently these glitches have gotten much more common and I fear more, perhaps more potentially deadly ones, could happen. Car has only 95k miles on it and has been well maintained.

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.

In june 2008, I bought a new 2007 toyota avalon at a local toyota dealership, harr toyota at 100 gold star blvd, worcester, ma 01606. I had been enjoying driving the car for the past 6 years and have always thought that the next vehicle for my family will be another toyota avalon. I liked it smooth drive, number of features, plenty of space and the most the reliability. All maintenance on the vehicle has been performed as required and I thought that as long as I take good care of it, I could drive it for many more years. Unfortunately, one week ago, when my family and I were traveling on the state highway, I-90, the cars speed dropped from about 67 MPH to 0 in a matter of seconds. The vehicle became unresponsive causing me a tremendous amount of stress. I must have been born under a lucky star? Because I was able to move to the break down lane without causing what could have been a major accident. I am sure that anyone that has had their loved ones at a great risk would understand my feelings. We received help from the state police in terms of towing the car to the nearest toyota dealership, bernardi toyota at 1626 worcester rd, framingham, ma. The problem with a car was identified as failure of the transmission system and the car was repaired at a cost of $5,100. Given the fact that the car has only 57,000 miles on it (minimal mileage when compare to the anticipated longevity and reliability of toyota) and one year past 5-year warranty (2008-2014) makes me extremely disappointed. I would appreciate you to strongly consider reimbursing me for the substantial cost of the repairs that were caused by what deemed a substandard original transmission in my vehicle. I look forward to your reply. Please contact me at the e-mail addresser by phone. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
