GM recalling 135,000 SUVs with plastic jacks that can break

General Motors is recalling 135,400 compact crossovers because their emergency jack can break under load. The problem occurs when the jack — which is plastic — isn't positioned correctly as detailed in the owner's manual. This can cause the jack to fracture. If the jack breaks and the vehicle collapses, there's a risk of injury or death, according to an NHTSA recall alert. The recall involves the 2020-22 Buick Encore GX and 2021-22 Chevrolet Trailblazer. A GM test driver discovered the problem when he broke a jack during a durability test on a Trailblazer. GM started investigating in April and found 21 claims of jack failures, including one reported injury. "This jack design may not be sufficiently robust against fractures if improperly or incorrectly positioned on the vehicle frame by the user," a NHTSA safety report said. GM will start notifying vehicle owners July 26. It will provide free replacement jacks that are made of metal.   Featured Gallery 2021 Buick Encore GX View 21 Photos Recalls Buick Chevrolet GM

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.

Texas cops pull armed suspect from burning car

A high-speed chase through Fort Worth, Texas ended in dramatic fashion earlier this month when FWPD pulled armed burglary suspects from the burning wreckage of their escape vehicle. According to NBC DFW, Fort Worth police were dispatched to Avington Way on the evening of July 16 to investigate reports of a burglary. The burglary victim told police he had arrived home to find three individuals hauling his property out of his house. When he approached them, one of the suspects pointed a handgun at him and told him to stay back. Then all three suspects climbed into a silver Dodge Avenger and sped away. FWPD officers spotted the Avenger a short time later on Sycamore School Road and, after the car refused to pull over, the chase was on. Police chased the burglary suspects through the city at speeds approaching 100 mph until the Avenger blew a red light and was t-boned by an oncoming pickup at the intersection of California Parkway and James Avenue. As the pursuing officers closed in on the disabled car, it suddenly caught fire. One suspect bailed out and ran for it, but the remaining two were trapped inside with the flames quickly mounting. Despite the spreading fire and the threat of armed suspects in the vehicle, police officers rushed to pull the men from the wreck. The driver was removed easily, but the passenger was unconscious and trapped behind a crushed passenger door. The scene was caught on the officers' body cameras as they pried the door open with their bare hands. Eventually the officers got the semi-conscious man out of the passenger seat just as the car was completely engulfed in flames. "It was pretty dramatic. We recruit people that can think on the fly, think quickly, and perform under pressure," FWPD Sergeant Marc Povero told WFAA. All three suspects are facing charges for burglary, and the driver was charged with evading arrest.
