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.

3 Quick Takes on the new Hummer EV

The 2022 GMC Hummer EV truck debuted Tuesday with 1,000 horsepower and up to 350 miles of range. It marks the return of the Hummer name after a decade-long absence and is the most ambitious electric vehicle General Motors has attempted. Here are three quick takes. This is how major vehicles will be revealed going forward The unveiling during Game 1 of the World Series on Fox and during The Voice on NBC could only have been bigger if done during the Super Bowl. A two-network debut complete with LeBron James providing voiceover for the commercial. On Fox, World Series play-play man Joe Buck neatly set up the spot and told millions of viewers that the order bank was now open. Then the Hummer debuted in what looked like a cut from the next Transformers movie. OK, this is not how every major car will be revealed, but the direct-to-consumer, as-many-eyeballs-as-possible, made-for-TV (or social media) event will be a key strategy going forward. In the last few months, the Detroit, Los Angeles and New York auto shows have all played leapfrog with dates, confusing many observers. The pandemic has obviously exacerbated the decline of auto shows, but if you’re an automaker, why share the spotlight in a convention hall? Most car reveals wonÂ’t be network TV spectacles, like the Hummer, but streaming services and other platforms will make a lot more sense than traditional means as companies compete for new buyers. This is how the Tesla Cybertruck should have looked Most would say the Hummer is pretty cool looking. The headlights, the grille, the blocky fenders and huge wheels — yeah, this looks straight out of central casting. ItÂ’s what you expected the reborn Hummer to look like, nominally now in the service of the GMC brand. Tesla made the Cybertruck a bit too crazy. Sure, itÂ’s attention-getting. But look at the Tesla. No one can objectively say the Cybertruck is aesthetically pleasing, from the shape to the features. ItÂ’s out-of-step with the graceful Model S and Model 3 sedans. The Hummer is futuristic, has interesting elements — like underbody cameras for off-roading and a T-top — and a massive presence. It doesnÂ’t need to do more. The addition of Super Cruise technology, however, is a nice touch. GM is serious about EVs The Hummer leads a blitz of EVs from GM, which is quietly yet ambitiously laying out an electric future.

GM looks to combat high theft rates on SUVs with added tech

The Cadillac Escalade has been at or near the top of most-stolen and insurance-loss lists for more than seven years, until it dropped to number six earlier this year. In 2011 it was fitted with a host of new security features to address its easy-to-override features and that has brought the number of thefts down, but when eight of the ten most stolen rides are large SUVs from General Motors, no one will argue that something else needs to be done.
Thus, GM has fitted this same theft-deterring tech to the 2015 Suburban, Tahoe and Yukon. The Suburban and Tahoe will get the steering lock that the Escalade and Yukon already get, plus bolted-down third-row seats to deter thefts like this, stronger door lock cylinders and shields, and side-cut keys to inhibit picking.
Additional security measures in a Theft Protection Package can be purchased for $395, consisting of sensors on the greenhouse glass and interior, an incline/tilt sensor and added "key control systems" to make it more difficult for the men in black balaclavas to steal what you bought.
