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

2015 Chevy Spark will have lighter, smaller battery

As General Motors gets ready to release the 2015 Chevy Spark EV, it is retooling the Brownstown Battery Assembly to build a new battery system for the chirpy little electric car. The new Spark will lose a few pounds and kWh from its lithium-ion pack, but it will keep all of it's performance specs. The current Spark EV uses a 21-kWh lithium-ion battery pack with bits made by A123 Systems (known as B456 Systems during bankruptcy). For the 2015 model, GM is going to build a 19-kWh battery system in-house that will use 192 LG Chem cells. Losing a bit of energy capacity means that the battery system for the 2015 Spark EV will be 86 pounds lighter but it will keep the EPA-rated 82-mile range and 119 MPGe. The 2015 Spark EV also keeps its $26,685 (plus destination) starting price from the 2014 model. The car will once again qualify for a federal tax credit of up to $7,500. LG Chem also supplies the cells for GM's other plug-in vehicles from its facility in Western Michigan. The Brownstown production line currently builds the battery packs for the Chevy Volt, the Opel Ampera and the Cadillac ELR. You can read our first drive of the 2014 Chevy Spark here. Brownstown Battery Assembly Expands Capabilities Will build battery system for 2015 Chevrolet Spark EV 2014-05-14 DETROIT – General Motors will bring all its electric vehicle battery building capabilities in-house with production of battery systems for the 2015 Chevrolet Spark EV at its battery assembly plant in Brownstown, Mich. "Using our in-house engineering and manufacturing expertise enabled us to deliver a battery system that is more efficient and lighter than the 2014 Spark EV without sacrificing range," said Larry Nitz, executive director of GM global transmission and electrification engineering. "Our successful working relationship with LG Chem has allowed us to deliver a new battery system for the Spark EV that helps us to better leverage our economies of scale." A newly designed battery system features an overall storage capacity of 19 kWh and uses 192 lithium ion cells. The cells are produced at LG Chem's plant in Holland, Mich. The battery system weight of 474 lbs. is 86 pounds lighter than the system in the 2014 Spark EV. The Spark EV battery is built on a dedicated production line at Brownstown, which also manufactures complete battery packs for the Chevrolet Volt, Opel Ampera and Cadillac ELR.

Travis Kvapil tells Twitter his Sprint Cup car was stolen

There's a bizarre story coming out of Atlanta today, as NASCAR racer Travis Kvapil is reporting that his Sprint Cup Car was stolen from a lot at the Drury Inn in Morrow, GA. Kvapil announced the theft, which included the black pickup that was hauling the trailer and the #44 Chevrolet SS Sprint Cup Car – shown above, with driver JJ Yeley at the wheel – on Twitter. According to Kvapil, the car wasn't going to be ready for the Thursday test session at Atlanta Motor Speedway, although forecasts of snow forced the team to dispatch their main trailer and tools to the track ahead of the car, which left for Atlanta later yesterday. According to ESPN, police in Morrow have video of the "incident," which happened at 5:34 AM Friday, with police investigating it as as criminal in nature. "Sometimes what happens when thieves see trailers, they might just assume there's something in the trailer they can go off and sell," Sgt. Larry Oglesby, of the Morrow PD, told USA Today. "Sometimes when things like this occur, they will drop off the items in a parking lot somewhere – like a Walmart parking lot – once they realize what they have." "All we know is it was a silver jeep," team owner John Cohen told USA Today. "One guy got out and they pulled off together." Earlier, Cohen told ESPN that the theft will force the team out of this weekend's race at the Folds of Honor QuikTrip 500, at Atlanta Motor Speedway. Kvapil, meanwhile, has taken to Twitter to appeal to his followers to be on the lookout for the truck, trailer and race car. Here's hoping it turns up all together. Check out the driver's tweets, below. Wow. Anyone near Atlanta find my stolen Cup car let me know!
