What are the reasons for the Buick Excelle not responding when attempting to start with power?
4 Answers
Buick Excelle not responding when attempting to start with power is caused by reasons such as the ignition switch not being in place or already damaged, severe battery drain, or damage to the starter relay. Below are specific details about the Buick Excelle: 2020 model launch: On September 18, 2019, SAIC General Motors Buick officially launched the 2020 Buick Excelle, with the all-new generation Excelle making its debut, comprehensively upgraded in design, power, fuel efficiency, safety, and connectivity. Positioning: The Buick Excelle is positioned as an entry-level family car, featuring a dynamic exterior, high-quality interior, a new drivetrain system, smooth and fuel-efficient performance.
Last time I drove a Buick Excelle, I also encountered a no-start situation where the battery had power but the engine just wouldn't crank. That day I spent the whole afternoon troubleshooting - first checked the fuse box and indeed found the starter circuit fuse had blown. Replacing it fixed the issue. If the fuse is good, the problem might be with the starter motor. These tend to fail over time - worn copper contacts inside or seized bearings can cause weak cranking. Also don't overlook the ignition switch - poor contacts or aged circuit boards are common culprits, especially in older models like the Excelle. I'd also recommend checking for loose or corroded battery terminals - just cleaning them might help. If all else fails, you'll need a professional scanner to read trouble codes - the anti-theft system might have falsely locked. Most importantly, don't mess around too long yourself - safety first. Remember to turn on hazard lights if stalled roadside. It's good to keep basic tools handy for simple fixes, but leave complex issues to the repair shop for peace of mind.
This situation is quite common with the Buick Excelle, and I think the key is to check a few points. A worn-out starter motor is the most likely culprit—problems with the gears or coils inside can cause a complete lack of response, often sounding like a clicking noise. Then, you need to inspect the starter relay; that little box is prone to burning out or poor contact, which can prevent current from reaching the motor. If the battery voltage is normal but there's no response when turning the key, it might be an internal short in the ignition switch, especially in older cars. Also, don’t forget to check the wiring connections—if the positive or negative terminals are dirty or loose, the current won’t flow properly. I’ve dealt with this before and fixed it by replacing the relay in time. Ignoring it for too long can lead to bigger issues, like a drained battery or even damage to the ECU. It’s a good habit to have the technician test the starting system during regular maintenance to avoid getting stranded in the middle of the night.
It's indeed frustrating when the Buick Excelle doesn't respond when trying to start. First, confirm the battery has sufficient charge - use a voltmeter to check for at least 12 volts. If you don't have a voltmeter, the dashboard lights coming on is a good sign. Next, inspect the starter-related fuses located in the fuse box, labeled 'start' or 'ignition'. Replace any blown fuses. If the fuses are intact, the starter motor might be faulty - common issues include seized bearings or worn brushes. Don't overlook potential relay failure either - this small component controls current flow and its malfunction prevents the motor from receiving start signals. I've fixed similar issues myself - sometimes simply cleaning corroded connections solves the problem. For safety, avoid repeated starting attempts to prevent component damage.
