2002 Buick Rendezvous Electrical Issues
Hey thread,
Is your alarm system factory or aftermarket? It sounds like the alarm system may be at fault! Let us know!

Also, it's not the regular car alarm that goes off --- it's more like the dinging sound that the car makes when you open the door when the car is on, however it's much faster.

Ok, then it sounds like the issue is in the body control module and I would have to recommend a trusted shop or a dealership for repairs as special equipment is required

Suggested Repair
Have the body control module diagnosed at a trusted shop or dealership, since special equipment is required. The heat-related false warnings, chime, lights, and locks after longer drives point to that module rather than an aftermarket alarm.
Conversation Summary
The owner of a 2002 Buick Rendezvous reported lights dimming at night and, after drives longer than about 30 minutes, false parking-brake, door, and hatch warnings, flashing fog lights, cycling locks and dome lights, and a rapid door chime that continued after shutdown until the battery was disconnected. The problem stopped once the vehicle cooled and did not occur on short trips. After confirming the system was factory equipment and the sound was a chime rather than an alarm, the expert attributed the fault to the body control module and recommended a trusted shop or dealership because special diagnostic equipment is required.
