GM recalling 2013 Buick LaCrosse, Cadillac SRX over transmission software

The National Highway Traffic Safety Administration has issued recalls for the 2013 Buick LaCrosse and 2013 Cadillac SRX due to a problem with the software for the transmission controller. On about 27,000 SRX and LaCrosse models, the transmission could accidentally be shifted to Sport mode, which would reduce the amount of engine braking drivers experience.
NHTSA says this could increase the risk of a crash, but, fortunately, the required fix is simply an update to the software.
While we're on the subject of General Motors vehicle recalls, a small number (48) of compressed natural gas versions of the 2011 Chevrolet Express are also being recalled for a potential risk of fire or explosion. Yikes. Both official recall notices are posted below.

2021 Buick Envision order guide shows $32,995 base price

Based on an early dealer guide Cars Direct got its hands on, the 2021 Buick Envision will bring more to the market than handsome new design inside and out. The 2020 Envision in 1SV and Preferred trims starts at $33,500 plus a $1,195 destination charge, totaling $34,695. The dealer guide shows the 2021 Envision Preferred starting at $32,995 after destination, a $1,700 cut compared to this year's model. The 1SV was also listed in the guide but didn't get a price. A Buick spokesperson confirmed to Cars Direct that the Preferred trim will be the new entry-level, so it appears the 1SV could go away. The two trims are equipped the same as standard, the difference being that Preferred opens up the options menu to features like the Active Package and a powered panoramic moonroof. That pricing puts the 2021 Envision thousands of dollars under of its luxury competitors like the Acura RDX, Audi Q5, Lexus NX, and Lincoln Corsair. The price of the middle Essence trim doesn't change, at $36,995 after destination.   The current Premium trim will be replaced by the Avenir trim. At present, the Premium trim only comes in all-wheel drive, which Buick has changed for the 2021 model year. A 2021 Envision Avenir with front-wheel drive will start at $41,395, which is $500 less than a 2020 Envision Premium with all-wheel drive. Adding power to the rear axle adds $1,800 to the price, the Envision Avenir AWD the most expensive model at $43,195. That's a $1,600 cut compared to the 2020 Envision Premium AWD. The only engine on offer will be a 2.0-liter turbocharged four-cylinder with 230 horsepower and 258 pound-feet of torque, the same engine in the 2021 Envision's E2 platform-mate, the Cadillac XT4. That output falls between the two engines that can be had on the 2020 Envision, either the base 2.5-liter four with 197 hp and 192 lb-ft, or an optional 2.0-liter turbo four with 252 hp and 295 lb-ft.  Related Video:

GM recalls nearly 24,000 Buick Regals for brake issue

Buick is recalling 2018-2020 model year Regals to address a software defect in the braking system that would result in a loss of power assist under certain circumstances, making the brakes difficult to operate and potentially leading to a crash. In total, 23,734 models are covered by the campaign. "In the event of a partial or full loss of vacuum-brake assist, the vehicle’s hydraulic-brake boost is designed to supply supplemental pressure to the vehicleÂ’s brake system. A software error in the electronic brake control module (EBCM) may fail to activate the hydraulic-brake boost under these conditions," GM said in its defect report to NHTSA. "If the vehicleÂ’s vacuum-power brake assist partially or fully fails, braking events may require additional stopping distance, depending on the brake pedal force applied by the driver. Increased stopping distances could increase the risk of a crash." GM says that a warning indicator will illuminate in the dash if the system completely fails, and drivers may notice an increase in brake pedal resistance. Failure will not render the brakes inoperable, but they will require more force to operate. GM has begun notifying dealers of the defect; owners should be notified starting in August.   Related video: Recalls Buick GM Safety Hatchback Wagon Sedan
