Acura TSX alarm sounds randomly, windshield wipers activate, left turn blinker stays on, and washer fluid sprays by itself on Acura TSX

Some Acura TSX owners report experiencing issues with their alarm system, including random alarm sounds, unexpected windshield wiper activation, a left turn blinker that stays on, and washer fluid spraying by itself. These problems may stem from a sensor issue where the alarm receives panic signals from the key fob without any buttons being pressed. Additionally, some owners have found that the windshield wipers activate unexpectedly due to electrical issues caused by water entering the vehicle through poor roof welds or inferior sealant. The malfunctioning left turn blinker may be linked to a faulty door pin switch or other electrical components. Moreover, spontaneous washer fluid spraying could indicate electrical malfunctions from water intrusion. To resolve these issues, it is advisable for owners to check the key fob for damage, ensure all doors are securely closed, and have a dealership conduct a thorough scan for internal faults. If water intrusion is suspected, professional inspection and repair of any leaks are recommended to prevent further electrical complications.
