GM to offer 2 years free maintance on most 2014 models

A day after Ford announced it was scaling back the complimentary maintenance program for its Lincoln brand, General Motors has gone in the completely opposite direction, offering most of its 2014 lineup with free maintenance. Since 2011, Cadillac models have all come with a four-year/50,000-mile complimentary maintenance program, but Chevrolet, Buick and GMC vehicles will now come standard with free maintenance for two years or 24,000 miles for the 2014 model year.
The program will give vehicle owners and lessees free oil changes, tire rotations and 27-point inspections following the recommended maintenance schedule laid out in each vehicle's owner's manual. We contacted GM to see which vehicles were eligible for the program, and a spokesperson got back to us with the following comment:
"All 2014 models are eligible, it's just that the included services vary by model, e.g., Spark EV would not need oil changes, Corvettes don't recommend tire rotations."

GM opens official investigation into C8 Corvette transmission leaks

In March 2020, a month after Chevrolet began customer deliveries of the 2020 C8 Corvette, a GM dealer technician created a Reddit thread about a leaking gearbox in a Corvette with 32 miles. That car hadn't even been sold yet. Since then, as a search of "C8 Corvette transmission leak" shows, it's been tales of woe for some owners. Something in the Tremec TR-9080 transaxle in the back of the mid-engined Corvette doesn't work as it should, the fault able to cause codes that the transmission needs service, or that the driver needs to shift to park. In some cases, the battery would die because of follow-on issues after the initial transmission code, that code preventing the car from powering down. As Autoevolution reports, GM filed paperwork with the National Highway Traffic Safety Administration in August to look into what's going on. Between forum threads and GM's investigation document, there are several issues mentioned. The most common appears to be the dual-clutch transmission leaking fluid due to gasket failures like the one suffered by one owner at 858 miles, and another for an owner currently enduring a second leaking transmission. The Midengined Corvette Forum reported that Chevy engineers redesigned the TR-9080 pan, fitting Corvettes with the new unit at some point in the 2021 model year. The original pan was stamped steel unit affixed to the engine with two studs and 13 bolts, plus "reinforcement plates." The updated pan is said to be a cast aluminum unit affixed with two studs and 17 bolts, omits the reinforcement plates, and gets a new machined new groove around its edge to seat the gasket seal. The GM paperwork now at the NHTSA mentions a P1789 code, and says one reason for it could be "debris on the park position sensor magnet causing an incorrect position reading to the TCM." This might be caused by another issue mentioned in forums, which is clogged transmission filters. GM gives instructions for returning transmission filters to the company, and a poster on one forum said the Corvette tech at the dealer where he bought his Corvette told him the automaker "requires every used transmission filter to be returned to GM."  Whatever's going on, the problems haven't stopped, and they go beyond the P1789 code. Over the weekend, a 2022 Corvette owner posted on Corvette Forums that he got a check engine light on his car after just 850 miles.

2023 GMC Hummer paint choices are out of this world

The 2022 GMC Hummer EV Edition 1 came in one color: Interstellar White. Despite production issues potentially pushing Edition 1 builds into the 2023 model year, the Edition 1 will stick to being bathed in that single brilliant shade. GM Authority says it got access to the color palette on the way for the standard series Hummer EVs due next year that shows seven new galactic-themed choices on the way. Interstellar White carries on, joined by Void Black as the only no-cost colors. The others are: Afterburner Tintcoat, said to be an orange hue; Deep Aurora Metallic, said to be some kind of bronze; Meteorite Metallic, said to be a gray; Moonshot Green Matte, which we've seen on early shots of the Hummer EV SUV; Supernova Metallic, said to be dark blue; Tide Metallic, said to be a different shade of blue. GMA didn't get intel on pricing for the cost-extra colors; right now, the most expensive palette option for GMCs is White Frost Tintcoat for $1,095. However, the outlet believes Moonshot Green Metallic will be "extremely limited" and charge a super premium price. If that ends up being the case, it suggests GM has a thing about getting big green for special greens. Cadillac made Dark Emerald Frost a late option on the 2022 CT4-V and CT5-V Blackwings and charged $3,925 for the matte paint job. The brand ended production of Dark Emerald Frost in January, making the color doubly exclusive since it was offered for less than a year at the same time as customer demand far exceeded the number of Blackwings available. Anyone wanting Moonshot on their Hummer should get in line early.  The 2023 GMC Hummer EV will begin production later this year. Last month, GM raised prices for the coming model year by $6,250, and raised the destination fee to $1,995. For the moment, that makes the Hummer EV 2 start at $86,245, the EV 2X at $96,245, and the EV 3X at $106,245. Related video: This content is hosted by a third party.
