Two problems related to alternator/generator/regulator have been reported for the 2003 Toyota Camry. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2003 Toyota Camry based on all problems reported for the 2003 Camry.
While driving the car, the engine and electrical components suddenly shut off. The first few times this happened, I was able to simply re-start the car with everything working again. I then brought the car to 3 different mechanics who could not find anything wrong with the battery or alternator (or anything else). The problem was erratic so it never occurred with the mechanics. Now the problem occurs occasionally when I turn the headlights or brights of the car on. The last time it happened (10/11/14) was while I was driving about 60 mph. The engine shut out, the dash lights went off (as well as all the other electrical things: gps, ac, radio, etc). Even the flashers would not turn on. Then, in a matter of moments, everything turned on again. The car's engine did not even need to be restarted. I was able to keep driving without incident for 20+ miles. This incident has happened a total of about 3-4 times in the past, however, it was not triggered in the past by turning the lights on. There was no apparent trigger at all. The problem is erratic and does not happen all the time.
Consumer states battery dose not produce enough power to run a/c and radio at same time. Dealer has been contacted,and replaced alternator.
