What are the reasons for the failure to open the electric tailgate of a Cadillac SRX?

Simply replacing the electric right-side strut can restore normal operation. Additional information: Precautions for replacing the right-side strut: 1. After replacing the strut, the tailgate will resume normal function, but the newly replaced strut will typically last only about a year. 2. For long-term considerations, it is best to replace the tailgate struts in pairs to maintain consistent internal pressure in both struts! Replacing only one side will accelerate wear and tear on the new strut. About electric tailgates: The electric tailgate of a car, also known as an electric trunk, refers to a trunk that can be opened or closed using electric power or remote control. To open the trunk, simply press the button inside the car or on the remote key, and the trunk will open automatically. To close the trunk, press the close button inside the trunk, the close button inside the car, or the remote key, and the trunk will close by itself.
I also encountered the issue of the power tailgate not opening when I drove the SRX before, and I've summarized a few common causes. A dead battery is key—after driving the car for several years, the battery ages and causes insufficient voltage, making the tailgate motor unable to operate. You should measure the voltage to see if it needs replacement. A blown fuse is the most common issue; take some time to check the fuse box in the trunk and replace it to fix the problem. Another reason could be a stuck sensor—if there’s dirt or debris blocking the area under the tailgate, the sensor may mistakenly detect an obstacle and prevent opening. Just clean it thoroughly. If mechanical parts like the motor or hinges are rusted, apply more lubricant for maintenance. If the problem occurs frequently, the control module might be faulty, and you’ll need to visit a 4S shop for diagnostics. Make it a habit to regularly clean the area around the tailgate and check electrical connections to avoid last-minute hassles.
From a maintenance perspective, SRX power tailgate failures are mostly electrical or mechanical issues. First, check for blown fuses located in the fuse box on the left side of the trunk - replacing with a new fuse often solves the problem. Wiring issues commonly involve aging breaks or short circuits, especially in vehicles with frequent door operation; inspect for loose wire connectors. Motor failure is another major cause, typically due to burnout from prolonged heavy use - simply replace with new parts. Control module malfunctions are also relatively common and require diagnostic tools to read error codes. It's recommended to avoid parking in high-humidity areas to minimize rust damage to components. When the tailgate won't open, use the manual emergency release cord (instructions are in the owner's manual).
I once encountered a situation where the SRX power tailgate suddenly wouldn't open, and it took me quite a while to figure out the reason. At first, I thought the remote control was out of battery, and replacing the battery solved the problem. Later, it malfunctioned again, and after checking, I found out it was a blown fuse, which I replaced myself. Sometimes, the tailgate sensor gets blocked by debris, and cleaning it restores normal function. I remember that time when the motor made a squeaking noise but didn't move, and it turned out to be worn-out parts after sending it for repair. From these experiences, most issues are minor, like battery or fuse problems. With regular maintenance and care, such problems occur less frequently.
