2022 GMC Sierra Super Cruise First Drive | Now with trailering and automatic lane-changing

Although the updated late-model year 2022 GMC Sierra is still a little ways off (In fact, it hasn't even been revealed), we've had an opportunity to try one of its headlining features: Super Cruise. But it's not quite the Super Cruise you know from the current Cadillac line. The new Sierra will be getting a newer version with two features: the ability to execute lane changes and passes automatically, and the ability to operate with a trailer. We tried the system at GM's proving grounds in Milford, Mich., and our test vehicles were 2022 Sierra prototypes. Though the trucks themselves are early examples with features not finalized, GMC representatives said the Super Cruise system is pretty much finished. The system uses close and long-range radar sensors at the front and a new set of radar sensors at the back, plus the truck's various cameras. It also utilizes the mapping data that GM has accumulated for the system to ensure it operates on approved roads and has detailed information about where the car is. Now, the first new feature enabled by the updated Super Cruise is the automatic lane-change system. The current system can change lanes on its own, but it must be prompted by a press of the turn signal. That feature remains intact, but now, if you approach a slower vehicle on a multi-lane highway, Super Cruise can check the lane next to you to see if it's safe to merge, change lanes, and then return to the original lane once the slow-moving vehicle has been passed. This is where those rear radar sensors come in. We tried it three times on GM's big banked oval course, and it did it impressively smoothly. It was able to make the decision proactively, too, making the decision to change a good distance before we were on top of the slow moving car. Oh, and of course, because this is Super Cruise, it all happened without us having to touch the wheel. Our automatic lane change test was followed by trying Super Cruise with a trailer. Now, it's important to note that the automatic lane-changing functionality won't work with a trailer. This is because that function depends on a set of radar systems at the back of the truck that are blocked by a trailer. Apart from that, the rest of Super Cruise's functions still work just fine. To make this possible (and safe), the system is able to estimate the weight of the trailer and adjust following distance accordingly, allowing it to safely slow down as needed.

2022 GMC Hummer EV voluntarily recalled for battery connector issue

When vehicles from certain automakers need to return to dealers for fixes but the National Highway Traffic Safety Administration isn't involved, these situations might be called "Customer Satisfaction Programs." It is, effectively, a voluntary recall. GM Authority notes that GM has issued one such program for the GMC Hummer EV and the Brightdrop Zevo 600 van (formerly the EV 600) to deal with a battery issue. In roughly 424 total units across both populations, the high-voltage connector might prematurely corrode. If this happens, water can leak through the connector into the pack. A warning light in the gauge cluster will alert owners to the condition. GM doesn't outline the possible results of water getting into the pack, but the outcome wouldn't be ideal.    The fix is a trip to the service bay to have a technician apply sealant to the high-voltage connector.   GM says it will get in touch with Hummer EV and Brightdrop owners about making appoints with dealers. Meanwhile, owners can contact GM Customer Service at 800-462-8782 and refer to Satisfaction Program No. N222362090. Owners can also visit the GM Recall Center page and insert their VINs to find out if their vehicles are affected. Since this isn't a recall overseen by the NHTSA, the issue isn't covered on the NHTSA's site. However, there are Manufacturer Communications between GM and the NHTSA related to other H2 issues such as a calibration issue with the Hummer EV's Extract Mode and the HVAC, so owners might want to visit SaferCar.gov for the whole picture.

GM warning 800,000 owners that their cars may need oil changes more frequently than they say

The days of changing your engine oil every 3,000 miles are long gone thanks to most cars having automatic oil monitoring systems, but about 800,000 General Motors vehicles apparently have incorrect monitoring software that is leading to premature engine component wear. According to Autoweek, certain 2010-2012 Buick LaCrosse, Regal, Chevrolet Equinox and GMC Terrain models equipped with 2.4-liter four-cylinder engines could be going too long in between oil changes resulting in a higher-than-normal number of warranty claims for the engine's balance chain. The balance chain links the balance shaft to the crankshaft, and a worn one can produce higher noise levels.
As a fix, GM dealers will be reprogramming the software for the monitors in an effort to reduce the interval between oil changes, which varies based on driving habits and conditions. Through February 2015, the software update will be done at no cost to vehicle owners, but since this is not a recall, after that point, it will be up to the discretion of dealers as to whether or not they will charge for the service. What isn't immediately clear is whether GM plans on giving assistance to out-of-warranty customers who are experiencing engine issues from the worn chain.
