Weekly Recap: The implications of strong new car sales

New car sales are on a roll in the United States this year, and analysts are optimistic the industry will maintain its torrid pace. Sales increased 1.6 percent in May and reached an eye-popping seasonally-adjusted selling rate of 17.8 million, the strongest pace since July 2005, according TrueCar research. That positions the industry for one of its strongest years ever, as consumer confidence, low interest rates, low fuel costs, and an influx of new products propel gains. In addition to the positive economic factors, May also featured warmer weather across much of the US, an extra weekend, and it came on the heels of relatively weak April sales. Analysts suggest income tax refunds and the promise of summer driving and vacations also traditionally help May sales. "While 2015 will be one of the best years in the history of the US industry, in some ways it may be the very best ever," IHS Automotive analyst Tom Libby wrote in a commentary. "Not only are new vehicle registration volumes approaching the record levels of the early 2000s, but now registrations and production capacity are much more closely aligned so the industry is much more healthy." Capacity, an indicator of the auto sector's health, is also expected to grow. Morgan Stanley predicts it will eventually hit at least 20 million units per year, as many companies, including General Motors, Ford, Tesla, and Volvo are investing in new or upgraded factories. "The best predictor of US auto sales is the growth in capacity, and frankly, we're losing count of all of the additions – there's literally something new and big every week," Morgan Stanley said in a research note. Transaction prices, another telling indicator, also continue to show strength. They rose four percent in May to $32,452 per vehicle, and incentives dropped $10 per vehicle to $2,661, TrueCar said. "New vehicle sector and segment preference indicates consumers are confident about the economy and their finances," TrueCar president John Krafcik said in a statement. Still, Morgan Stanley noted the robust sales did little to immediately impact automaker stock prices and suggested it might be a prime time to sell if sales reach the 18-million pace. "Perhaps the biggest reason may be that investors have seen this movie before," the firm wrote.

GM will recall 3.5 million pickups and SUVs to fix brake issue

WASHINGTON — General Motors Co is recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and increase the risk of a crash. The recall, which covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles, was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted Wednesday. NHTSA opened a preliminary investigation into the issue in November 2018, and said it had reports of 9 crashes and two injuries related to the issue. It provided GM in July with additional field reports that prompted the automaker to open an investigation. The company did not immediately say on Wednesday how many injuries or crashes are linked to the issue but said it could impact braking in "rare circumstances." GM said dealers will reprogram the Electronic Brake Control Module with a new calibration that will improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Recalls Chevrolet GM GMC

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.
