Cadillac's Super Cruise — look, Elon, no hands!

Cadillac is about to start selling vehicles with an autonomous driving mode and TechCrunch got an early look at the technology in a production car. "Wait for the green light and let go," the Cadillac engineer instructed. That's it. The car was driving itself. I, the person behind the steering wheel, was no longer the driver. Cadillac's Super Cruise system was driving. The 2018 Cadillac CT6 sped along U.S. 23 under the direction of Super Cruise. Traffic was light and the weather was perfect. The system held the Cadillac sedan in lane and responded appropriately to traffic. I spent an hour on the expressway and touched the steering wheel and pedals only a few times. Super Cruise made the drive boring. I think that's the point. Here's how it works Super Cruise is available once the driver navigates the vehicle onto an expressway. When ready, a little icon is displayed by the speedometer and the driver hits a button on the steering wheel to switch it on. Once the light bar on top of the steering wheel turns green, the driver can let go. Super Cruise is driving.This steering wheel light bar is key to the operation. When green, the driver knows Super Cruise is in control. Blue means the driver interrupted the system to change lanes and red means Super Cruise needs the driver to confirm they're paying attention and not checking Twitter. When active, Super Cruise controls the steering and speed, but again, only on an expressway. This is done through onboard sensors and using GPS and mapping data. GM employed GeoDigital, a startup in GM Venture's portfolio, to map 160,000 miles of expressways in the U.S. and Canada. The car company then used Super Cruise-equipped vehicles to test each mile. This combination of onboard systems combined with map data makes the system feel polished and sophisticated. During my admittedly limited time in the vehicle, the CT6 precisely held its position in the lane and confidently handled sweeping curves at speed. There was no wiggling or squirming — from the Cadillac or myself. The car was in control, and I felt safe. Although the driving conditions were perfect for my test ride, during adverse weather, the system will work normally until one of the key systems is unable to operate.

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.

Cadillac recalls ELR coupe over stability control problems

Cadillac is recalling about 656 2014 ELR models made between September 26, 2013 and February 14, 2014, because of a fault with the electronic stability control system. On cars without adaptive cruise control, it's possible that diagnostics could prevent the system from telling the driver if ESC is on or off.
Cadillac has a software fix ready and repairs begin on April 17. Alan Adler, General Motors' recall and legal spokesperson, tells Autoblog that only about 55 of the affected cars are in the hands of owners. The rest are either on dealer lots or still at the factory. There have been no reported injuries or crashes caused by the fault.
The correction for the stability control system involves a software recalibration of the electronic brake control module that takes around 20 minutes to perform. While they use the same platform, the Chevrolet Volt isn't involved in this recall because it "uses a different a brake control module," said Adler.
