GM will recall 3.5 million pickups and SUVs to fix brake issue

WASHINGTON — General Motors Co is recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and increase the risk of a crash. The recall, which covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles, 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 Wednesday. NHTSA opened a preliminary investigation into the issue in November 2018, and said it had reports of 9 crashes and two injuries related to the issue. It provided GM in July with additional field reports that prompted the automaker to open an investigation. The company did not immediately say on Wednesday how many injuries or crashes are linked to the issue but said it could impact braking in "rare circumstances." GM said dealers will reprogram the Electronic Brake Control Module with a new calibration that will 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. Recalls Chevrolet GM GMC

Junkyard Gem: 1988 Chevrolet Spectrum Sport Coupe

Before General Motors created the Geo brand for cars built or designed by its overseas partners, the Chevrolet Division put its badges on U.S.-market versions of the Toyota Corolla Sprinter, the Suzuki Cultus and the Isuzu Gemini. Those cars were known as the Nova, the Sprint and the Spectrum, and all became Geos starting with the 1989 model year. Today's Junkyard Gem is one of the last Chevy Spectrums ever sold, found in a Denver self-service yard a few months ago. Midway through 1988, the Chevrolet Spectrum abruptly became the Geo Spectrum and was assigned to the 1989 model year. This car was built in May 1988, making it one of the very last of the pre-Geo Spectrums. The Chevrolet/Geo Spectrum was available as a four-door sedan and as a three-door hatchback, from the 1985 through 1989 model years. For 1988 only, a Spectrum Sport Coupe package, featuring some trim upgrades and these rad decals, could be had on the hatchback. This car was essentially identical to its Isuzu-badged counterpart, the I-Mark. In 1988, the MSRP for the cheapest possible Chevy Spectrum hatchback (the stripped-down Spectrum Express) was $6,495, while its somewhat better-equipped I-Mark twin started at $7,439 (that's $17,128 and $19,617 in 2023 dollars). Meanwhile, the base Hyundai Excel hatchback listed at $5,295 and the Yugo GV cost a hilarious $4,199 ($13,963 and $10,941 in today's money). Power came from this 1.5-liter SOHC four-cylinder, rated at 70 horsepower. A turbocharged version with 110 horsepower was available as well. You could get an automatic transmission in the Spectrum, but this car has the base five-speed manual. This car didn't get the optional air conditioning, but at least it has the traditional Isuzu HVAC control icons featuring blow-dried hair and high-heeled dominatrix boots. Just over 170,000 miles on the odometer. Someone installed a pretty good (for the 1980s) Blaupunkt Charlotte CR148 cassette deck in the dash. This was a necessity if you wanted to enjoy full appreciation of the music of the era. The Spectrum is special! It's as slick as city rain. "I didn't spend a lot of money but with my Spectrum it looks like I did." Joe Isuzu mocked Toyota salesmen when pitching the I-Mark. As was nearly always the case during the 1980s, the JDM ads for the same car were much more fun. They should have recreated this commercial with Spectrums.

2016 Chevy Volt will have more EV range, bigger battery

Meet the new Volt, not the same as the old Volt. That appears to be the story when General Motors introduces the 2016 Chevy Volt at the Detroit Auto Show in January. Today we're getting some more details on the guts of the new plug-in hybrid, and it turns out they're going to be much improved from the current Volt, which first went on sale at the end of 2010. Sure, the first-gen Volt did get some improvements along the way (a slightly larger battery pack, lane departure warnings) but the new Volt – which will go on sale in the second half of 2015 – marks the first time GM has been able to return to the drawing board and really make the improvements that its customers want. That's how Larry Nitz, GM's executive director of vehicle electrification explained it to AutoblogGreen today when explaining the all-new Voltec extended range electric vehicle (EREV) powertrain. "In the Gen 2 is we gave the engine a little more power, a little more torque, a little more displacement, more capability." – Larry Nitz Nitz said that the new Volt will be better in almost every sense: a bigger battery, longer EV-only range, 20 percent better acceleration in the low speed range and higher overall efficiency. This is due, in part, to the Volt's two motors being able to both act as generators and power the car. As we noted this morning, the 2016 Volt will use a larger, 1.5-liter four-cylinder engine, a version of which is already used in the Chinese-market Cruze. Nitz said that this has a number of benefits, including more power and quieter operation. "Some people would say, why did you make [the first-gen engine] so big. I would say, why did you make it so small?" he said. "It works good, our customers love it, but the reality is that if you go a little bit off and use the car a little harder, you can get the engine to need to operate at a higher speed. In an EV, that's quite noticeable. So, what we did in the Gen 2 is we gave the engine a little more power, a little more torque, a little more displacement, more capability and what it has marginally enabled is not only is it more efficient but it's also quieter." Nitz wouldn't talk about how the new powertrain might affect the two other products that use the Volt's underpinnings – the Cadillac ELR and the Opel Ampera – but if you've got a quieter option, we assume that's something ELR drivers would enjoy. But that's a story for another day.
