Porsche and Buick earn top honors in J.D. Power Sales Satisfaction Index Study

Customer satisfaction with car buying has been at a low point over the past few years, as price increases, inventory shortages, and COVID restrictions have complicated every part of the process. There are signs of improvement, however, as J.D. Power’s 2023 U.S. Sales Satisfaction Index Study showed that customer satisfaction has improved slightly from a year ago. J.D. Power rates satisfaction on a 1,000-point scale, finding that it improved seven points to 793 from last year. Improving inventory levels and a slow leveling off of prices have contributed to that improvement, and fewer people are paying above MSRP for new cars. Some auto brands performed better than others with sales satisfaction. Porsche ranked highest among premium brands, followed by Alfa Romeo. Buick took the top spot among mass-market brands, with GMC, Chevrolet, and Mitsubishi behind. J.D. Power also handed out segment-level awards: Premium Cars: Porsche Premium SUV: Porsche Mass-Market Car: Chevrolet Mass-Market SUV/Minivan: GMC Mass-Market Truck: GMC Despite the increase in sales satisfaction, thereÂ’s still room for improvement to reach pre-pandemic levels. J.D. Power noted gaps in salesperson knowledge as an area of improvement. Buyers rated salespeople much better during a gas vehicle purchase than with EVs, citing their expertise as a challenge. Pricing remains a challenge despite an improvement since 2022, and satisfaction is still below pre-pandemic levels. Mass-market buyers reported a slight bump in satisfaction, while premium buyers felt that pricing was less fair than a year before. ItÂ’s an interesting contrast, showing that dealer pricing tactics can significantly impact satisfaction with the sales process. Fewer people may be paying more than MSRP, but several premium models still list with significant markups. Even more interesting is PorscheÂ’s top spot on the satisfaction list, as its cars often sell with huge upcharges, and itÂ’s exceedingly tricky even to get a build allocation for some models.

GM removes start/stop from full-size trucks and SUVs with V8 engines

GM is removing start/stop technology from a number of its popular full-size SUVs due to the ongoing chip shortage. This follows the removal of cylinder deactivation technology from some of its trucks, which was also due to the chip shortage. GM Authority first reported the news, but we’ve just confirmed everything with a GM spokesperson.  The following 2021 model year vehicles will be affected: Chevy Tahoe, Chevy Suburban, GMC Yukon, Cadillac Escalade, Chevrolet Silverado 1500 and GMC Sierra 1500. Only versions of those vehicles built with the 5.3-liter V8 or 6.2-liter V8 and mated to the 10-speed automatic will have the tech removed from them. Only vehicles manufactured on or after June 7 will be affected. “By taking this measure, it will enable us to continue production of our high-demand full-size SUV and pickups as the industry continues to rebound and strengthen,” GM said in a statement. Those who ultimately buy one of these vehicles without start/stop technology will receive a $50 discount off MSRP for their troubles. Losing this fuel-saving tech could be a big negative for some, but we know many folks turn it off anyway. Not having to press the button to deactivate start/stop every time could actually be a positive if youÂ’re part of the camp who does that already. 2021 Cadillac Escalade Sport Platinum View 27 Photos On the downside, GM says “most of the affected vehicles will experience a minor reduction in fuel economy.” We donÂ’t have revised window stickers in hand to know how each model will be affected, but any 1 mpg reduction will be rather impactful for vehicles rated as low as these trucks already are. Any reduction will be seen in the city mpg rating, so take the kind of driving youÂ’re going to be doing into account before purchasing. When it comes to greenhouse gas compliance rules, GM says it doesnÂ’t foresee this impacting the companyÂ’s average fleet score. It also intends to begin adding start/stop back to these models as soon as possible, but there will be no retrofit effort made to fit the tech to vehicles already built without it. “Our supply chain organization continues to make strides working with our supply base to mitigate the near-term impacts of the semiconductor situation,” GMÂ’s statement reads. “GM continues to leverage every available semiconductor to build and ship our most popular and in-demand products, including our highly profitable full-size trucks and SUVs for our customers.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).
