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.

Here are all the EVs with 800V charging available in 2024

As technology advances, electric cars are improving their fast-charging times. That means less time spent waiting at a DC public charger when you’re out on the road. While Level 3 chargers used to provide a maximum of 150 kilowatts of power, 350-kW chargers are become more common, making for super-fast charging Â… if your car is capable of taking advantage of it. So how do automakers improve the charging speed of their EV batteries? Some are turning to higher voltage, specifically 800V charging. What's the difference between 800-volt charging and 400-volt charging? So how does 800V charging improve upon the more common 400V EVs? Put simply, the higher the voltage, the less amperage (current) it requires to charge. In other words, with more voltage, you get more wattage (power, aka charge rate) from the same amperage (current). 800V architecture is also more efficient, with less electrical resistance, so it can use thinner cables and smaller, lighter components while needing less cooling. The tradeoff is that it is more costly, and guess who that cost gets passed on to. While automakers don't break down their pricing to show how much more you're paying for that 800V system, you'll just have to evaluate any potential purchases as a whole, and make your decision based on overall pricing of the vehicle. Thankfully, the 800V EVs on sale now are generally ones we like. Now, 800V charging capability doesn't necessarily mean an EV has 800V vehicle architecture. For instance, the GMC Hummer EV and Chevy Silverado EV operate at 400V, but with their dual battery packs, can switch to 800V when charging by temporarily connecting those packs in series. Currently, there are only a handful of EVs available with 800V charging. But if you are going to find yourself taking longer trips in your EV and using DC fast chargers more often, you might want to consider choosing one with this faster charging capability. With that in mind, these are the EVs available with 800V charging, either on sale now or coming in 2024. 800-volt EVs available in 2024 Audi E-Tron GT Chevrolet Silverado EV Genesis GV60 Genesis Electrified G80 Genesis Electrified GV70 GMC Hummer EV Pickup GMC Hummer EV SUV GMC Sierra EV* Hyundai Ioniq 5 Hyundai Ioniq 6 Kia EV6 Kia EV9 Lotus Eletre* Lotus Emeya* Lucid Air Lucid Gravity* Porsche Macan Electric* Porsche Taycan Ram 1500 REV* Tesla Cybertruck *Coming later in 2024 Green Audi Chevrolet Genesis GMC Hyundai Kia Lotus Porsche Tesla Electric Lucid EV charging

New GMC feature reminds drivers to check for kids in hot cars

We see the stories every summer: Dozens of children die from heat stroke every year after being left inside hot cars. GMC has introduced a feature in the 2017 Acadia in an effort to help curb the problem. Simply called Rear Seat Reminder, it alerts the driver if the vehicle suspects someone might have been accidentally left behind. GMC's alert will trigger under certain circumstances. Five chimes will sound and a warning will display if the rear doors are opened and closed within 10 minutes of the vehicle starting or if those doors are opened while the vehicle is running. The system does not sense items or people in the rear seat like the front passenger seat would to trigger the airbag. Warnings will be displayed regardless of interior or exterior temperature; while the summer months are the deadliest, leave-behind deaths occasionally occur during cold weather. Drivers should be aware that temperatures in vehicles can quickly rise to dangerous levels, even if the ambient temperature seems cool and comfortable. View 23 Photos Unfortunately, a large percentage of children are intentionally left in cars. A negligent caretaker, whether it be a parent, grandparent, or babysitter, can leave a child behind while they go to work or run an errand, not expecting any problems. Some children unintentionally trap themselves in cars while playing in the cabin or trunk. The Acadia's system is unlikely to prevent these scenarios. While we believe that GMC should be commended for making an effort to put an end to these tragedies, we're not certain how effective the system might be until driver education improves. It's also possible drivers will come submit to warning fatigue and begin to ignore the messages. That said, if this software-based solution prevents just one death, it was worth the effort.
