Why Does My Car Shake When Braking? A Guide for Tri-Cities, WA Drivers

If you have been shopping for a new Buick or GMC vehicle, you have probably noticed the term Super Cruise appearing across multiple models. GM Super Cruise is one of the most advanced hands-free driving systems available on any vehicle today. Here is everything Tri-Cities shoppers need to know about what GM Super Cruise is and how it works at Speck Buick GMC in Pasco. What Is GM Super Cruise? GM Super Cruise is General Motors' hands-free driver assistance technology. It allows compatible vehicles to drive hands-free on pre-mapped highways under the right conditions. Super Cruise is not a self-driving system and it requires the driver to remain attentive at all times. A built-in driver attention camera monitors your eyes and face while Super Cruise is active. If you look away from the road too long, the system will alert you to retake control immediately. How Does GM Super Cruise Work? GMC Super Cruise and Buick Super Cruise use several advanced technologies working together seamlessly: LiDAR Map Data Super Cruise uses a precise LiDAR-based map database of compatible highway roads across North America. Super Cruise only activates on roads included in the pre-mapped database. High-Precision GPS GPS positioning locates your vehicle on the LiDAR map in real time to within centimeters of accuracy. This precise positioning is essential for the system to operate safely and effectively. Driver Attention Camera A small infrared camera monitors your eyes and head position continuously during Super Cruise operation. If you look away too long, the system provides escalating alerts to retake control immediately. Adaptive Cruise and Lane Centering Once activated, Super Cruise manages your vehicle's speed, following distance, and lane centering automatically. The system adjusts your speed based on traffic conditions on compatible roads. Which Buick and GMC Vehicles Have Super Cruise?

If you are shopping for a new GMC Sierra HD in the Tri-Cities, WA, one of the biggest decisions you will face is gas vs diesel. Both engines are capable and well-suited for Eastern Washington driving. However, each one has distinct advantages depending on how you use your truck every day. Here is a complete gas vs diesel comparison and quick recommendations for Tri-Cities GMC Sierra HD buyers. The Engines: GMC Sierra Gas vs Diesel GMC Sierra Gas Engine 6.6L V8 Gas · 401 HP · 464 lb-ft Torque The GMC Sierra gas engine is a proven workhorse that handles the vast majority of heavy-duty tasks with ease. It is available at a lower upfront purchase price than the diesel option. The gas engine also requires less specialized maintenance than a diesel engine over the life of the truck. GMC Sierra Diesel Engine 6.6L Duramax Turbo Diesel · 470 HP · 975 lb-ft Torque The GMC Sierra diesel engine delivers significantly more torque than the gas engine. That massive torque advantage is why so many Eastern Washington farmers, ranchers, and contractors choose diesel over gas. The Duramax diesel also delivers better fuel economy than the gas engine on long highway hauls. Towing and Payload Comparison Spec Gas 6.6L V8 Duramax Diesel Max Towing (2500 HD) 17,340 lbs 22,100 lbs Max Towing (3500 HD SRW) 21,200 lbs 27,000 lbs Max Towing (3500 HD DRW) 23,100 lbs 36,000 lbs Max Payload (3500 HD) 7,234 lbs 7,234 lbs Horsepower 401 HP 470 HP Torque 464 lb-ft 975 lb-ft All figures are for properly equipped configurations. Always verify on the door jamb sticker for your specific truck. Local Driving Scenarios: Which Engine Is Right for You? Scenario 1: Yakima Valley Farmer or Rancher You regularly haul livestock trailers and heavy equipment across Benton County and the Horse Heaven Hills. Your loads frequently approach or exceed 18,000 pounds behind the truck. Recommendation: GMC Sierra Diesel The Duramax diesel's massive torque advantage and superior towing capacity make it the clear choice. The diesel's better fuel economy on long hauls also reduces operating costs significantly over time. Scenario 2: Tri-Cities Contractor You use your GMC Sierra HD for hauling materials and equipment around Kennewick, Richland, and Pasco job sites. Your loads are consistently heavy but rarely exceed 15,000 pounds behind the truck. Recommendation: GMC Sierra Gas The gas engine handles typical contractor loads comfortably and costs less upfront. City driving and short trips do not favor the diesel's fuel economy advantage as much as long highway hauls do. Scenario 3: Weekend Recreational Tower You tow a fifth-wheel camper or large boat on weekends with a typical trailer weight between 14,000 and 18,000 pounds. You regularly travel long distances to campgrounds in the Blue Mountains and Columbia River Gorge. Recommendation: GMC Sierra Diesel The diesel's torque advantage makes towing a heavy fifth-wheel noticeably more relaxed on long highway stretches. Better fuel economy on highway hauls also saves meaningful money over a season of weekend trips. Scenario 4: Light to Moderate Work Truck You need a heavy-duty truck occasionally but most daily use involves lighter loads and everyday driving around the Tri-Cities. Your trailer weights rarely exceed 12,000 pounds. Recommendation: GMC Sierra Gas If your loads stay comfortably within the gas engine's capability, the lower upfront cost and simpler maintenance make more financial sense for your situation. Cost Comparison: Gas vs Diesel Upfront Purchase Price The Duramax diesel option typically adds $10,000 or more to the purchase price over the equivalent gas model. Fuel Costs Diesel fuel is sometimes more expensive than regular gasoline at Tri-Cities fuel stations. However, the diesel's superior fuel economy on long hauls can offset the higher per-gallon cost for high-mileage drivers. Maintenance Costs Diesel engines require more specialized and sometimes more expensive maintenance than gas engines. Diesel oil changes cost more and diesel engines also require regular diesel exhaust fluid (DEF) refilling. Long-Term Value Diesel-equipped GMC Sierra HD trucks typically command a stronger resale value than equivalent gas models at trade-in time. Quick Recommendation Summary Choose the GMC Sierra Diesel if you: Regularly tow more than 15,000 pounds behind your truck Put high annual mileage on your truck through long highway hauls Need maximum towing confidence for fifth-wheel or gooseneck applications Plan to keep your truck long term and want strong resale value Choose the GMC Sierra Gas if you: Tow moderate loads within the gas engine's comfortable capability Do primarily city and short-distance driving around the Tri-Cities Want a lower upfront purchase price and simpler maintenance Use your truck as a daily driver with occasional heavy-duty hauling needs Come See Both Options at Speck Buick GMC Ready to compare gas vs diesel GMC Sierra HD options at Speck Buick GMC in Pasco?
