GM to make most cars LTE hotspots for 2015

General Motors isn't the first automaker to deliver in-car Internet access, but a proposed plan announced today could make the technology more widespread than any of its competitors have offered. By the 2015 model year, most Chevrolet, Buick, Cadillac and GMC products in the US and Canada will offer 4G LTE mobile broadband access. Initially, GM will just be pairing with AT&T to deliver this service, but additional carriers will be revealed in the future.
Current in-car Wi-Fi hot spots are limited to 3G, but GM says that 4G LTE is 10 times faster than 3G service and will allow for full Internet access, including streaming video for entertainment as well as services like real-time traffic updates and navigation driving directions. There is also no need for a paired smartphone with this new system, which should make it easier to use, and GM and AT&T will also be working together to develop new apps for customers.
Buyers can expect to start seeing 4G LTE in their cars starting next year, and GM is already planning to expand the service to other global markets as well. All of the information from GM's announcement is posted in a press release below.

GM faces possible class action lawsuit over 8-speed transmission

General Motors has been hit with a class-action lawsuit from owners who allege the eight-speed automatic transmission found in several rear-wheel-drive Chevrolet, Cadillac and GMC models between the 2015 and 2019 model years has a defect that causes the vehicles to hesitate and jerk when accelerating or slowing down. The lawsuit was posted to ClassAction.org and spotted by GM Authority. Problems with GM's Hydra-Matic 8L90 and 8L45 transmissions have been well-documented on Internet forums and via complaints filed with the National Highway Traffic Safety Administration, with many reporting damage to their vehicles. The lawsuit was first filed in December in U.S. District Court for the Southern District of Florida but appears to have been transferred recently to New York. Autoblog sought comment from Theodore Leopold, the lead attorney for the plaintiffs. "These transmissions have a common defect," the complaint reads. "Drivers attempting to accelerate or decelerate their cars feel a hesitation, followed by a significant shake, shudder, jerk, clunk, or 'hard shift' when the vehicle's automatic transmission changes gears." The problem also occurs when the vehicles accelerate in a single gear, without shifting, the plaintiffs allege. "Drivers have reported that the shift is sometimes so violent, they feel as though they have been hit by another vehicle." The problem is believed to center on the transmission, torque converter or both. The complaint says it causes undue friction, causing hydraulic systems and gears to function improperly and sometimes leaves metal shavings throughout the transmission, leading to costly repairs and replacement of parts or the entire transmission. It says GM has known about the problems since shortly after it introduced the transmissions, and has issued 13 technical service bulletins, none of which have resolved the problem. GM declined to comment on the lawsuit. The plaintiffs say GM should have warned consumers about the issues and covered repairs under each vehicle's three-year/36,000-mile bumper-to-bumper warranty. They're seeking statewide classes in at least six states: California, Florida, Illinois, New York, Oklahoma and Texas.

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.
