Just because you aren’t buying a brand-new vehicle doesn’t mean you should have to compromise security and confidence. If you're looking for a quality pre-owned SUV but want more peace of mind than a handshake can give you, the Buick Certified Pre-Owned benefits program is worth a close look. Whether you're shopping from Mandan, Bismarck, or anywhere in between in North Dakota, understanding what CPO means for Buick can help you make a smarter, more confident buying decision. What Is the Buick Certified Pre-Owned Program? The Buick Certified Pre-Owned benefits program is designed to give buyers the reliability of a new vehicle purchase with the value of a pre-owned price. To qualify, vehicles must meet strict age and mileage requirements. Then they must pass a 172-point inspection covering everything from paint to brakes. Anything not up to standard must be repaired or replaced. This means every Buick CPO vehicle has been carefully reviewed before it ever reaches the lot. You're not just buying a used car—you're buying one that's been held to a higher standard. CarBravo is GM’s Certified Pre-Owned marketplace where you can browse vehicles and learn more about the program. The Buick CPO Warranty One of the biggest draws of a Certified Pre-Owned Buick is the coverage that comes with it. The Buick CPO Bumper-to-Bumper Limited Warranty covers CPO vehicles less than 10 model years old with less than 100,000 miles. You get 12 months or 12,000-mile coverage with no deductible that includes a long list of components. The BravoBudget Powertrain Limited Warranty covers CPO vehicles between 10 and 15 years old with mileage between 100,000 and 150,000 miles. Its added protections like these that reflect the confidence Buick has in their vehicles’ reliability and quality. Additional Buick Certified Pre-Owned Benefits Worth Knowing But wait, there’s more! CPO Buick vehicles include 24/7 roadside assistance, making it easier to handle unexpected situations no matter where you're driving. Every Buick CPO vehicle also comes with a CARFAX® Vehicle History Report, so you can review the vehicle's background before committing. That kind of transparency matters, especially when you're making a significant purchase. Beyond the warranty itself, Buick Certified Pre-Owned benefits extend to the ownership experience. CPO buyers may have access to special financing rates through GM Financial, which can make monthly payments more manageable compared to standard used vehicle financing. Some offers may also include trial periods for OnStar®, Buick's connected services platform, which provides features like emergency response, turn-by-turn navigation, and vehicle diagnostics. The myBuick mobile app is another perk worth mentioning. CPO owners can use it to access vehicle information, schedule service, and stay connected to their Buick from their smartphone. It's the kind of ownership support that typically comes with a new vehicle purchase—extended to the CPO experience as well.

Diesel Truck Winter Maintenance: A September Prep Guide for GMC Duramax® Owners
If you own a Duramax®-powered GMC Sierra, don’t wait until the first freeze to think about your diesel truck’s winter maintenance. September is the ideal window to assess your truck's condition before cold temperatures make every task harder. Drivers in Mandan, North Dakota know how quickly conditions can shift, and getting ahead of the season now means fewer surprises when it matters most. Check Your Fuel System for Cold-Weather Readiness Diesel fuel behaves differently in cold weather than gasoline does. As temperatures drop, diesel can begin to gel, restricting flow through your fuel lines and filters. One of the most important GMC Sierra Duramax® cold weather tips is to switch to a winter-blend diesel fuel or add a quality anti-gel fuel additive before temperatures dip below freezing. You should also replace your fuel filter if it is overdue, since a clogged filter puts extra strain on the system when the engine is working hardest. Inspect Your Batteries and Electrical System Diesel engines rely on strong battery power to fire up in cold weather because they require higher compression to ignite. A battery that functions adequately in summer may struggle to turn over a Duramax® engine on a January morning. Have your battery load-tested in September while conditions are still manageable. Check the terminals for corrosion, inspect the cables for wear, and confirm that your alternator is charging properly. Many Duramax® trucks use dual batteries, so both units need to be evaluated. Review Your Coolant and Glow Plugs Your cooling system plays a critical role in diesel truck winter maintenance. Verify that your coolant mixture provides adequate freeze protection for the low temperatures common in Mandan, ND. A 50/50 mix of coolant and distilled water is a reliable starting point, but North Dakota winters may call for a richer coolant concentration. While you’re at it, have your glow plugs inspected. These components pre-heat the combustion chambers to help the engine start reliably in cold weather, and a failing glow plug can lead to hard starts or misfires. Evaluate Your Oil Viscosity Engine oil thickens in cold temperatures, which slows lubrication at startup—the most wear-intensive moment for any engine. Check your owner's manual for the recommended cold-weather oil viscosity for your specific Duramax® engine. Switching to a lower-viscosity oil for winter months can help ensure that critical components are protected from the moment you start your truck. This is one of the simplest, but most effective cold-weather tips for your GMC Sierra’s Duramax® engine that you can act on right now. Prepare Your Tires and Brakes Traction and stopping power are non-negotiable when snow and ice arrive. Inspect your tire tread depth and sidewalls for any cracking or damage. If you run all-season tires, confirm they’re rated for winter conditions. Examine your brake pads and rotors as well, since cold weather can expose weaknesses that are less noticeable during summer driving. A truck that tows or hauls through winter weather needs a braking system that’s fully up to the task.
