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.

IIHS: High numbers of drivers treat partially automated cars as fully self-driving

WASHINGTON — Drivers using advanced driver assistance systems like Tesla Autopilot or General Motors Super Cruise often treat their vehicles as fully self-driving despite warnings, a new study has found. The Insurance Institute for Highway Safety (IIHS), an industry funded group that prods automakers to make safer vehicles, said on Tuesday a survey found regular users of Super Cruise, Nissan/Infiniti ProPILOT Assist and Tesla Autopilot "said they were more likely to perform non-driving-related activities like eating or texting while using their partial automation systems than while driving unassisted." The IIHS study of 600 active users found 53% of Super Cruise, 42% of Autopilot and 12% of ProPILOT Assist owners "said that they were comfortable treating their vehicles as fully self-driving." About 40% of users of Autopilot and Super Cruise — two systems with lockout features for failing to pay attention — reported systems had at some point switched off while they were driving and would not reactivate. "The big-picture message here is that the early adopters of these systems still have a poor understanding of the technologyÂ’s limits," said IIHS President David Harkey. The study comes as the National Highway Traffic Safety Administration (NHTSA) is scrutinizing Autopilot crashes. Since 2016, the NHTSA has opened 37 special investigations involving 18 deaths in crashes involving Tesla vehicles and where systems like Autopilot were suspected of use. Tesla did not respond to requests for comment. Tesla says Autopilot does not make vehicles autonomous and is intended for use with a fully attentive driver who is prepared to take over. GM, which in August said owners could use Super Cruise on 400,000 miles (643,740 km) of North American roads and plans to offer Super Cruise on 22 models by the end of 2023, did not immediately comment. IIHS said advertisements for Super Cruise focus on hands-free capabilities while Autopilot evokes the name used in passenger airplanes and "implies TeslaÂ’s system is more capable than it really is." IIHS in contrast noted ProPILOT Assist "suggests that itÂ’s an assistance feature, rather than a replacement for the driver." NHTSA and automakers say none of the systems make vehicles autonomous. Nissan said its name "is clearly communicating ProPILOT Assist as a system to aid the driver, and it requires hands-on operation.

2016 Chevy Volt ads strike frustrating, yet familiar, chord

Sometimes, it's hard to let go. In the six years that GM has been advertising and selling the Chevy Volt, one dominant message is that the car is an EV without any range anxiety. On the one hand, this is a positive thing: our car does something that other electric vehicles don't. Of course, there's another, more reasonable take on the message that EVs only equal limited range: don't promote this viewpoint if you ever plan on selling a pure EV. But, of course, this is exactly what GM is doing with a new ad for the 2016 Chevy Volt. Called Elevator, the spot (watch it above) compares driving an all-electric car with riding in an elevator getting stuck. Your Nissan Leaf might run out of electricity, the ad says, and that would be as uncomfortable as being trapped between floors. The main problem, of course, is that Chevy also offers the Spark EV and is getting ready to sell the Bolt EV. Does the company think that everyone will forget these anti-EV commercials when it come time to shop for a Bolt? Even worse, does GM think we've forgotten the Anthem ad for the Volt back in 2010? Apparently, so. Elevator isn't the only ad for the 2016 Volt that GM debuted today. The other, called Time Capsule (below), takes a swipe at the Toyota Prius. Trouble is, there are two easy ways to dismiss this ad as well. First, and most obviously, if GM is against using old technology, then why does it continue to shove a 100-year-old fossil fuel engine into almost every car it builds? Second, attacking the Prius for using 15-year-old tech – when said tech is still able to mop the floor with any hybrid from GM in the fuel economy race - is more like an admission of defeat than anything to be proud of. "Hey look, the Prius uses technology from the '90s," GM says. To which the observant viewer will ask, "Well, then why can't you build a 50-mile-per-gallon hybrid, GM?" It's also worth noting that Chevy has been on a misguided advertising streak as of late. We bashed their ads that suggested its Silverado is better than the F-150 because it uses steel instead of aluminum, too, especially since those commercials used shark cages and stupid superhero costumes in an attempt to make a point. Chevy, stop assuming we're all idiots. Please. Now, the 2016 Volt is a great car and I know that GM can make a darn good Volt ad (like this one), so seeing the company shoot solid fuel-efficient technologies in the back (again and again) is just frustrating.
