Trucks and tidbits from GM's earnings report

General Motors announced this morning that 2018 was a good year for it financially, thanks in large part to the company's performance in North America, which was predicated, according to the company, on "strong pricing, surging crossover sales, successful execution of the company's full-size truck launch, growth of GM Financial earnings, and disciplined cost control." GM reported full-year income of $8.1 billion and EBIT-adjusted income of $11.8 billion. Crossover sales in 2018 were 1,034,808, an increase of 7 percent compared to 2017 deliveries. Throw in the body-on-frame SUVs and the ute number is a total 1,295,700. But let's face it: It is the trucks that really matter. The Chevy Silverado and Colorado, the GMC Sierra and Canyon. Altogether, GM sold 973,463 pickups in the U.S. in 2018. Although Ford gets bragging rights for F-Series sales, GM gets to point out that it has a greater aggregate number. An important factor regarding the trucks and the reported income is that during the last quarter, more than 90 percent of the new 2019 trucks were crew cabs (which have a higher sticker), and at GMC more than 70 percent were Denali and AT4 models (which have even higher stickers). According to reporting by Bloomberg, GM's pickup trucks combine for $65 billion in annual revenue. Clearly when the 2018 sales of the Silverado — 585,581— dwarf the combined sales of both Buick (206,863) and Cadillac combined (154,702), pickups are what matter to the overall health of the company in a way that it is difficult to otherwise achieve. The "disciplined cost control" is something that is very much in the public eye right now, as the company is taking out thousands of its workers, and there is still the "unallocated" plant situation and other plants that will remain under capacity. The numbers in GM's earnings report probably made Unifor members' heads explode in consternation, coming fresh off their Super Bowl ad: " GM, you may have forgotten our generosity, but we'll never forget your greed." But there are a couple of curiosities in the full GM earnings release. One is that so far as its autonomous efforts go, it mentions only that (1) in the first quarter of 2018 Cruise introduced a production-ready autonomous vehicle, and (2) Cruise attracted $5 billion in external capital from SoftBank and Honda. Not a whole lot of love for autonomy. Good thing they have the trucks to fund the program, to say nothing of the external capital.

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.

GM tells 2021 Chevy Express and GMC Savana owners to park vans outside due to fire risk

GM is telling owners of certain 2021 Chevrolet Express and 2021 GMC Savana work vans to park them outside and away from other vehicles and structures due to a fire risk. Additionally, the company is recalling 10,154 of the vans it believes to be at risk of catching fire. The breakout is 7,891 for Chevy and 2,223 for GMC.  Only vehicles equipped with the 6.6-liter V8 (the new-for-2021 engine option) are included in the recall, and it’s limited to vans produced on or prior to December 7, 2020. The problem stems from some anti-rotation tabs on the positive battery terminal that are too close to a fuse block assembly attachment post. This lack of clearance could cause the tabs to come into contact with the fuse block, causing a short circuit. GM points out that a short-circuit of this nature could cause battery drain or lead to a fire under the hood. Your warning for the time being will come in the form of a low battery voltage warning, or you might just wake up with an unexpected dead battery. GM says that it first opened an investigation into this problem on January 26 this year after it was notified of an underhood battery fire on a 2021 Express. The investigation found three other underhood fires and concluded that these fires were originating from the positive battery cable attachment near the fuse. This recall was officially posted on March 11 this year, and the National Highway Traffic Safety Administration just sent a notification out to the media yesterday. The fix is a relatively simple one. Dealers are going to remove a portion of the anti-rotation tab on both positive battery cable terminals near the fuse block assembly attachments. This increases the clearance and eliminates the risk of fire, GM says. The job will be done under warranty, and GM says it will begin contacting owners for recall work on May 3 this year.
