One problem related to alternator/generator/regulator has been reported for the 1999 Toyota Camry. The most recently reported issues are listed below.
Since 2007 I have noticed some type of engine difficulty with the Toyota. The engine shuts off while running (it is an automatic transmission. ) also, alternator and battery receive too high a charge resulting in computer system overheating. I have replaced both alternator and battery several times, much more than necessary and problem remains with the obd system. This also causes engine to have surges of power while driving affecting cruise control. . . I don't know if this is also a problem relative to current Toyota issues-online someone has a 2002 solara with same problem. My parents have 01 solara-no problems reported. My old Lexus had similar problems my 1989 celica was a great car. Would not own again-would like to sell nut concerned for safety of any future owner(s. ).
