2023 J.D. Power Initial Quality Study shows there's less quality than last year

Vehicle inventory, vehicle pricing, and the supply chain are finally showing improvement. Vehicle quality, on the other hand, is still going the wrong way. That's the takeaway from the 2023 J.D. Power Initial Quality Study that found overall problems exceeded last year's record high. The study surveyed owners of 2022-model-year vehicles to assess the average rate of problems per 100 vehicles (PP100) during the first 90 days of ownership. The average figure for the 32 ranked manufacturers in 2020 was about 166 problems per 100 vehicles. In the 2021 IQS, that dropped to an average of 162. For 2022, the average jumped to 180 problems. For 2023, the PP100 is up to an industry average of 192 — an increase of 30 problems per 100 vehicles in just two years. Let's get to the good news first: Dodge reclaimed the crown of having the lowest number of problems per 100 vehicles at 140. Buick won last year with 139 PP100, falling to third this year. Dodge was the first American automaker to top the IQS in 2021. Its return as the least problematic gives parent company Stellantis three wins in four years after Ram was crowned in 2021. It also gives U.S. brands a four-peat after Buick topped the chart in 2022 by having owners report the fewest problems. This year's top 10 is Dodge, Ram, Alfa Romeo, Buick, Chevrolet, GMC, Porsche, Cadillac, Kia, and Lexus. Stellantis gathered a few feathers for its cap, in fact. Maserati showed the largest improvement year-on-year, followed by Alfa Romeo, and Alfa Romeo posted the lowest PP100 among the premium class, beating Porsche and Cadillac. Alfa Romeo has been vocal about working to improve quality, mentioning Lexus as a target. Last year the Japanese brand finished sixth, the Italians finished near the bottom, between Jaguar and Mitsubishi. This year Alfa jumped to third, Lexus dropped to tenth. Ram was the third-best on the list of improvers from 2022 to 2023.   The individual model with the lowest PP100 is the Nissan Maxima. Now for the troublesome bits. In the words of Frank Hanley, senior director of auto benchmarking at J.D. Power, "The industry is at a major crossroad and the path each manufacturer chooses is paramount for its future.

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.

Car owners getting more irritated with their repair experiences, study says

The J.D. Power U.S. Customer Service Index Study (CSI) is a barometer of a vehicle owner's happiness with the service experience. While it wasn't all bad in the 2023 study, the overall owner satisfaction score dropped. This year's tally of 846 out of 1,000 is two points down from 2022, the 43-year-old study's first decline in more than 28 years, and one point down from 2021. However, the overall score remains well up from the pre-pandemic scores of 821 in 2018 and 837 in 2020. The study claims the stumbling block is the horde of BEV launches. The flood into the new energy space has created a recall rate among EVs that's more than double the rate for ICE vehicles. Furthermore, dealership service department knowledge of EVs isn't on par with internal combustion engine expertise, leaving EV owners less satisfied with service advisors compared to ICE owners. Chris Sutton, VP of automotive retail at J.D. Power, said, "As training programs for service advisors and technicians evolve, EV service quality and customer experience must address both the vehicle and the unique customer needs. The EV segment has the potential to spur massive convenience improvements in how customers service their vehicles — but weÂ’re not seeing the benefits yet." Matters are slightly worse for all owners, though, with labor and parts shortages contributing to longer wait times for service appointments. The CSI study surveys owners and lessees of one- to three-year-old vehicles to gauge their happiness with service at franchised dealer or aftermarket service facilities for maintenance or repair work. The criteria in order of importance are service quality (32%); service advisor (19%); vehicle pick-up (19%); service facility (15%); and service initiation (15%). Lexus retains the top spot for luxury brands, giving it three wins in four years. The Japanese automaker won in 2020 as well, its run interrupted by Porsche in 2021. Cadillac, Infiniti and Acura complete the luxury top 5.  For mass-market cars, Mitsubishi wins again after a victory in 2021 and falling to fourth last year. It's followed by Mazda, Buick, Subaru and Mini.  Considering the different service needs and service experience of different body styles, the study has broken results out by segment for the first time. Lexus earned a second victory thanks to winning the premium SUV segment, and Mitsubishi earned a second victory by winning the mass-market SUV/minivan category.
