GM recalling 686k Lambda-platform models for hatch repair

General Motors is recalling 686,287 units of its Lambda platform crossovers. On models equipped with a power rear hatch the system can potentially fail. This campaign includes the 2008-2012 Buick Enclave, 2009-2012 Chevrolet Traverse, 2007-2012 GMC Acadia, and 2007-2010 Saturn Outlook. According to GM's documents to the National Highway Traffic Safety Administration (as a PDF), dirt can get into a portion of the strut that holds up the hatch and cause the part to prematurely fail. There's a redundancy in place called the Prop Rod Recovery system that's designed to shut the liftgate if there's a malfunction. However, if the breakdown happens too quickly after the hatch is opened the prop rod might not work the way it's supposed to. If someone were in the way of the falling liftgate, they could be hurt. For the repair, dealers will update the software for the power liftgate actuator motor control unit to prevent the hatch from closing so quickly. They'll also check the operation of the system afterward.

The affected vehicles, equipped with the power liftgate option, have gas struts that hold the power liftgate up when open. These struts may prematurely wear and the open liftgate may suddenly fall. CONSEQUENCE: If the open liftgate unexpectedly falls, it may strike a person, increasing their risk of injury. REMEDY: GM will notify owners, and dealers will update the software for the power liftgate actuator motor control unit so that the motor will prevent the rapid closing of the lift gate, free of charge. The manufacturer has not yet provided a notification schedule.

2020 GMC Acadia AT4 Review | A soft-roader in steel-toed boots

For carmakers today, the perfect lineup would be focused almost entirely on trucks and crossovers, favoring profitability at the expense of diversity. Just look at FCA’s Ram and Jeep showrooms. In the General Motors portfolio, that brand is GMC, with not a car to be found in its lineup and several body-on-frame offerings meant to take a serious beating. It should be a license to print money. But a lineup of trucks and SUVs isnÂ’t enough. Some folks want the rough-and-tumble edge of an off-road vehicle, albeit one that can still credibly serve duty in the school pickup line. Enter the AT4 trim level, an off-road package that spans the gap between the GMC's upscale professional image and the off-road oriented buyer. The 2020 GMC Acadia AT4 is the latest member of the family AT4 slots in between the mid-grade SLT and the range-topping Denali, but simply saying itÂ’s the second-most expensive Acadia variant isnÂ’t really doing it justice. If the SLT trim is understated, and the Denali trim opulent, the AT4 trim promises ruggedness and adventure – even if it canÂ’t deliver it.  The Acadia is definitely a soft-roader and AT4 doesnÂ’t do much to change that – itÂ’s effectively an appearance package. It adds a unique grille, 17-inch wheels and AT4 badges — all blacked out — plus a set of Continental TerrainContact A/T tires engineered to offer a comfortable ride while still enabling some off-pavement excursions. There are several unique interior treatments as well, including “AT4” embroidery on the seats, regardless of whether you go with the base upholstery or the upgraded perforated leather ($1,000) that was added to our test vehicle. Note that we didnÂ’t mention anything beyond the small wheels and meaty tires that would actually make the AT4 any better off pavement. ThereÂ’s no extra ground clearance (it remains a meager 7.2 inches), low range 4x4 system or suspension enhancement to be found here. This would be a departure from other GMC AT4 models, including the Sierra 1500 and upcoming 2021 Yukon, which get extra ground clearance, underbody protection and a rugged suspension, but it won't be an outlier. The similarly soft-roading Terrain AT4 has already been announced.  Yet, off-road models tend to get hammered with on-road handling and ride quality criticism and here's where the Acadia AT4 being more of an appearance package pays off.

GM recalls 3.8 million vehicles in North America due to braking issue

WASHINGTON — General Motors Co said Wednesday it was recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and that has been linked to 113 accidents and 13 injuries. The recall covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles. In late June, GM recalled 310,000 vehicles in Canada for the same issue. GM did not immediately explain why the Canadian recall occurred more than two months before it called back the vehicles in the United States. The recall was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted on Wednesday. The NHTSA opened a preliminary investigation into the issue last November, and said it had reports of nine related crashes and two injuries. It provided GM in July with additional field reports that prompted the automaker to open an investigation. GM said it could affect braking in "rare circumstances." The NHTSA said in a statement the "vehicles may experience brake boost failure, which would require increased brake pedal effort, leading to a hard brake pedal feel, and potentially increased stopping distance." GM said dealers will reprogram the electronic brake control module to improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Separately, GM said on Wednesday it is recalling 270,000 additional U.S. vehicles in three smaller recalls, including 177,000 2018 Chevrolet Malibu cars with 1.5L turbo engines because an error in the engine control module software may result in the fuel injectors being disabled.
