2020 Chevy Silverado, GMC Sierra recalled due to faulty brake component

General Motors is recalling 2020 Chevrolet Silverado 1500 and GMC Sierra 1500 pickups to fix a defect in the trucks' brake system. Certain Silverado and Sierra pickups were produced with brake-caliper bolts that were not heat-treated. Without heat-treating, the bolts are weaker than they should be, and there is a risk that they could fail, which would affect the trucks' braking performance, possibly leading to a crash. In total, 20,352 vehicles are affected. Owners of affected trucks will be contacted by GM. Dealers will inspect the bolts and replace those that are defective. Related Video:      

2016 Chevy Volt powertrain technical details

The last time General Motors launched a Chevy Volt, it was operating without really knowing how people would use the plug-in hybrid. Sure, it had experience with the EV1, but the Volt was a new kind of car, and you can see in the archives just how much time GM spent explaining this fresh, new powertrain to potential customers. Then, once the vehicle was released, the company collected voluntary data from a large number of owners to learn about their driving and charging habits. The company also asked them what they wanted most in the new version. There's got to be an algorithm buried somewhere in GM headquarters that was used to take all of the numbers GM collected and spat out the headline figures for the 2016 Volt: 50 miles of EV range and 41 miles per gallon. Another important number – price – is something GM isn't talking about yet (expect it in April or May), but the company is sharing some powertrain details about the upcoming car. At a preview lunch in Detroit last week for the SAE 2015 Hybrid & Electric Vehicles Technologies Symposium that's happening now in California, GM engineers Peter Savagian (who is presenting a paper on the new inverter used in the updated Volt) and Tim Grewe (talking about the entire second-generation powertrain) sat down with AutoblogGreen to tell us about the Volt's all-new propulsion system: The overall gist is that the new Voltec 5ET50 drive unit is lighter, smaller and more powerful thanks to a redesigned two-motor traction drive. As previously reported, the new engine is a 1.5-liter DOHC four-cylinder that offers 101-horsepower (at 5,600 RPM). Grewe said it's "great for range extension." The electric motor side of the powertrain offers 149 motoring horsepower from a two-motor, continuously variable transaxle. Initially, the new engine will be made in Mexico. GM will move production to Flint, MI during the first year it makes the 2016 Volt. The battery is slightly bigger in the new Volt – 18.4 kWh compared to 16.5 in the current-gen – and will have less range variation in the cold. GM is also using more of the overall capacity in the pack in the 2016 Volt than in previous versions, but is not saying how much more. GM is not ready to publish acceleration times just yet, but the 2016 Volt has improved numbers, especially when going from 30-60 miles per hour. Most everything on the new powertrain has become more efficient compared to the first-gen Volt.

Chevy Tahoe-to-K5 Blazer conversion shop renders Jimmy option

Back in 2019 we told you about a truck that looked like a K5 Chevy Blazer, but was actually a modern late-model Tahoe underneath. It was the product of Arkansas shop Flat Out Autos, which reskinned modern GM full-size SUVs to look like their predecessors. Now, the same shop is planning to release a GMC version, converting Yukons to Jimmys. We were impressed by Flat Out's workmanship, beautifully blending the lines of the Blazer into those of the Tahoe. The result was a cohesive design, not just a panel swap. It clearly required a lot of work, which helped justify the $69,000 price tag, not including the cost of the donor Tahoe. FlatOut Autos GMC Blazer Tahoe reskin 01 View 11 Photos At least one new owner was so impressed that they recently purchased four identical Blazer conversions at once. The quadruplets were all finished in blue with a white roof and all based on brand-new 2020 Tahoes. Obviously, with such demand it was only natural for Flat Out to explore other options. On Facebook the company said it was working on a 1972 version with an eggcrate grille. Now, they've also released a rendering paying homage to the K5 GMC Jimmy. The Jimmy conversion uses the original's quad-headlight face, crosshair grille and GMC badging. Like the Blazer conversion, it adds chrome bumpers and milled door handles while adapting the original's 2-door design to the new truck's 4-door body. The rendering only shows the front three-quarter view, but presumably a new carbon fiber rear door would have to be created as the Blazer's says "Chevrolet" across the back. Flat Out says that all the modern conveniences found on the donor Tahoe will work on the conversion, including parking, blind spot and lane keeping sensors. If you have the coin, it's a great way to have retro style without giving up modern safety and performance. The new Blazer has been disappointing to many fans that had hoped for a Bronco-like SUV. Instead, GM gave us a crossover. The Flat Out conversions might be a good compromise, and expanding it to the GMC brand only makes sense. Obviously there's no requirement to use a GMC Yukon as the donor vehicle for the Jimmy, as it's functionally identical to a Tahoe, but wouldn't you want to keep it in the family? Related Video:
