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

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.

GM reworking mandatory OnStar plans for some 2024 models

For the 2023 model year, GM added its OnStar and Connected Services plan as standard equipment to a large number of Buick, GMC, and Chevrolet vehicles. Folding the $1,500 retail price into the MSRPs of models like the GMC Acadia and Buick Encore plumped up prices beyond the usual year-on-year bumps. Looks like there's a reversal in play for 2024, GM Authority reporting that many of the models fitted with OnStar and Connected Services — now called OnStar Premium — will step down to three years of OnStar Remote Access standard.   OnStar Remote Access comes with these features: Remote key fob, vehicle locate, and remote personalization through mobile and in-vehicle apps. Three additional features can be added to the plan: OnStar Guardian, in-vehicle hotspot, and Super Cruise. Owners can also upgrade to OnStar Premium if they choose.  Higher trims like Buick's Avenir and GMC's Denali, plus the GMC Hummer and the Cadillac Escalade will retain OnStar Premium as standard equipment. That suite starts with Remote Access and adds: Automatic crash response, stolen vehicle assistance and recovery, OnStar Guardian, in-vehicle app access, unlimited streaming, three years of Super Cruise on vehicles with the hardware, and six months of SiriusXM radio. The Escalade puts a cherry on top with three years Sirius XM instead of six months. The Remote Access plan normally charges $14.99 per month. We're not sure yet if GM will subtract the cost of OnStar Premium from the MSRP and add the $540 for OnStar Remote Access, or if the trial period comes free of charge. Even if that's what happens, the change could take nearly $1,000 off the MSRP of a car like the GMC Acadia before any 2024 increases. We'll know more as the 2024MY models roll out and prices are announced. Related Video 2022 Buick Enclave Avenir revealed
