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.

Buick takes top spot in 2022 J.D. Power Initial Quality Study

People, economies, and supply chains weren't the only things continuing to get sick over the past year. The 2022 J.D. Power Initial Quality Study (IQS) is out, showing the average rate of problems per 100 vehicles (PP100) during the first 90 days of ownership increased overall. The average figure for the 32 ranked manufacturers in 2020 was about 166 problems per 100 vehicles. In the 2021 IQS, that dropped to an average of 162. This year, the average jumps to 180 problems. J.D. Power says that figure is a record high over the 36-year history of the study. Buick leapt to the top of the rankings this year with the fewest issues, at 139 problems per 100 vehicles in the first 100 days of ownership. After Dodge became the first American automaker to lead the IQS in 2020, followed by Ram in 2021, this year marks a three-peat for U.S. carmakers. Dodge took second this year at 143 PP100, Chevrolet third with 147 PP100, Genesis the first luxury maker on the chart in fourth with 156 PP100. Between February and May, this year's study gathered responses to 223 questions from more than 84,000 new 2022-model-year car owners and lessees. The questions are designed to zero in on real-world problems new owners encounter with nine categories of vehicle features: Infotainment; features, controls and displays; exterior; driving assistance; interior; powertrain; seats; driving experience; and climate. As has been the case in the past few year, infotainment has proved to be the most problematic bugbear making scores worse. Considering features individually, six of 10 of the worst problem areas dealt with infotainment, causing infotainment's score of 45 PP100 to be 19.5 PP100 worse than the second-placed feature. Consumers ranked getting Android Auto and Apple CarPlay to connect reliably as the most troublesome.  GM didn't just score with Buick, which was one of only nine of the 33 ranked brands to show improvement this year. The conglomerate earned first place with the fewest PP100 among all the automaker groups, and scored the most model-level awards with nine, ahead of BMW with eight and Hyundai Group with three.  This year's study again showed a gap between luxury and mass-market makers, thought to be down to the amount of tech in luxury vehicles that consumers aren't properly informed about or that doesn't act as expected — that latter issue exacerbated by the chip shortage.

Cadillac CT6 production ceases January 2020 as part of D-Ham layoffs

General Motors filed paperwork under the Worker Adjustment and Retraining Notification Act with Michigan's Department of Labor and Economic Opportunity this week, detailing events to come at the automaker's Detroit-Hamtramck Assembly Plant. Starting February 28, 814 salaried and hourly workers at D-Ham, as its called, will be laid off. The 753 workers represented by the UAW will begin receiving offers in January to relocate to facilities in Michigan and Ohio, or buyout offers. As the 4-million-square-foot plant winds down through April 3 to a skeleton crew, the Cadillac CT6 ceases production in January 2020, and the last Chevrolet Impala comes off the line on February 28. The loss of the CT6 represents the end of Cadillac's latest brief, and highly regarded, adventure into flagship sedans. It might also mean the end of the 4.2-liter Blackwing twin-turbo V8 engine, at least for the moment. Both casualties are calamities. The death of the Impala closes the door on a nameplate in production for 52 years since 1957, having started off as a top-tier trim for the 1958 Bel Air known as the Bel Air Impala, once advertised with the line, "Lets you know you're the boss." As part of the new four-year labor agreement with the UAW, GM is keeping D-Ham open to build a new line of battery-electric vehicles, ultimately investing $3 billion and tripling employment to 2,225 workers when fully operational. The agreement described the coming EV as a "van" that would commence production in late 2021, but various reports say what's actually coming is a range of premium EVs in pickup and SUV bodystyles under the program codename BT1. The easy predictions put an electric GMC Sierra and Cadillac Escalade among the EV fold, but not until 2023, according to auto industry forecaster LMC Automotive. Before that, LMC claims an electric van will debut in late 2021, along with a battery-powered rebirth of the Hummer brand in pickup and SUV forms, also in late 2021.
