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.

GM can't keep up with most popular pickup orders

With the market for pickup trucks at its best since before the recession, General Motors can't afford any hiccups with the launch of its new 2014 Chevrolet Silverado and GMC Sierra twins, but it sounds like the popularity of V8-powered trucks is causing some supply-chain issues. Bloomberg reports that GM is experiencing a shortage of 5.3-liter V8 engines because an unnamed parts supplier has been unable to keep up with demand. This is leading GM to restrict the number of V8 Silverado and Sierra trucks that Chevrolet and GMC dealers are allowed to order.
Although it's unclear how long it will take to resolve the parts shortage, GM doesn't have much time to sort it out, as a new Ford F-150 looms on the horizon. At launch, GM's fullsize trucks were offered only with a base 4.3-liter V6 and the 5.3-liter V8, but a burlier 6.2-liter V8 will be available soon. Interestingly, at least at the moment, GM truck buyers don't seem as willing to downsize to V6 power as buyers of the F-150, which gets some 42-percent of its sales from trucks equipped with its EcoBoost V6 engine (not including the normally aspirated base V6).
Working out the kinks in the Silverado and Sierra's supply chain couldn't be more important to the health of the company. Full-size pickups are a huge profit driver - in 2012, the trucks were said to make up about two-third of GM's total profits.

These are the cars with the best and worst depreciation after 5 years

The average new vehicle sold in America loses nearly half of its initial value after five years of ownership. No surprise there; we all expect that shiny new car to start depreciating as soon as we drive it off the lot. But some vehicles lose value a lot faster than others. According to data provided by iSeeCars.com, trucks and truck-based sport utility vehicles generally hold their value better than other vehicle types, with the Jeep Wrangler — in both four-door Unlimited and standard two-door styles — and Toyota Tacoma sitting at the head of the pack. The Jeep Wrangler Unlimited's average five-year depreciation of 30.9% equals a loss in value of $12,168. That makes Jeep's four-door off-roader the best overall pick for buyers looking to minimize depreciation. The Toyota Tacoma's 32.4% loss in initial value means it loses just $10,496. The smaller dollar amount — the least amount of money lost after five years — indicates that Tacoma buyers pay less than Wrangler Unlimited buyers, on average, when they initially buy the vehicle. The standard two-door Jeep Wrangler is third on the list, depreciating 32.8% after five years and losing $10,824.

On the other side of the depreciation coin, luxury sedans tend to plummet in value at a much faster rate than other vehicle types. The BMW 7 Series leads the losers with a 72.6% drop in value after five years, which equals an alarming $73,686. BMW's slightly smaller 5 Series is next, depreciating 70.1%, or $47,038, over the same period. Number three on the biggest losers list is the Nissan Leaf, the only electric vehicle to appear in the bottom 10. The electric hatchback matches the 5 Series with a 70.1% drop in value, but since it's a much cheaper vehicle, that percentage equals a much smaller $23,470 loss.
