What do J.D. Power's quality ratings really measure?

Check these recently released J.D. Power Initial Quality Study (IQS) results. Do they raise any questions in your mind? Premium sports-car maker Porsche sits in first place for the third straight year, so are Porsches really the best-built cars in the U.S. market? Korean brands Kia and Hyundai are second and fourth, so are Korean vehicles suddenly better than their US, European, and Japanese competitors? Are workaday Chevrolets (seventh place) better than premium Buicks (11th), and Buicks better than luxury Cadillacs (21st), even though all are assembled in General Motors plants with the same processes and many shared parts? Are Japanese Acuras (26th) worse than German Volkswagens (24th)? And is "quality" really what it used to be (and what most perceive it to be), a measure of build excellence? Or has it evolved into much more a measure of likeability and ease of use? To properly analyze these widely watched results, we must first understand what IQS actually studies, and what the numerical scores really mean. First, as its name indicates, it's all about "initial" quality, measured by problems reported by new-vehicle owners in their first 90 days of ownership. If something breaks or falls off four months in, it doesn't count here. Second, the scores are problems per 100 vehicles, or PP100. So Power's 2015 IQS industry average of 112 PP100 translates to just 1.12 reported problems per vehicle. Third, no attempt is made to differentiate BIG problems from minor ones. Thus a transmission or engine failure counts the same as a squeaky glove box door, tricky phone pairing, inconsistent voice recognition, or anything else that annoys the owner. Traditionally, a high-quality vehicle is one that is well-bolted together. It doesn't leak, squeak, rattle, shed parts, show gaps between panels, or break down and leave you stranded. By this standard, there are very few poor-quality new vehicles in today's U.S. market. But what "quality" should not mean, is subjective likeability: ease of operation of the radio, climate controls, or seat adjusters, phone pairing, music downloading, sizes of touch pads on an infotainment screen, quickness of system response, or accuracy of voice-recognition. These are ergonomic "human factors" issues, not "quality" problems. Yet these kinds of pleasability issues are now dominating today's JDP "quality" ratings.

Porsche recalling 24,500 Panameras for a potential HVAC coolant pump issue

A possible coolant pump problem for the HVAC system is causing Porsche to recall 24,467 units of the Panamera from the 2017 to 2020 model years. Bentley's recalling 650 examples of the sibling 2020 Continental GT for the same issue. Porsche was notified of a malfunction in the external heat pump for the Panamera's climate control in December 2022. An automaker investigation found that it's possible for excess humidity or even liquid to get past the pump seals and short out the pump's circuit board and connector. In rare instances, the malfunction could cause a fire. This can happen even when the engine is turned off because the cars in question are equipped with a residual heat function that keeps warming the cabin after shutdown. Panameras built after July 26, 2021 were fitted with a different pump. The Stuttgart carmaker's field analysis showed "a very small number of instances of thermal damage possibly attributable to this issue." Bentley changed the part in July 2019 to a model with a pressure compensation seal. Porsche said it will begin notifying owners on March 27. It also said it will reimburse any Panamera owners who have paid to have the part fixed previous to this recall. The fix is a trip to the dealer for a new pump with better sealing, sourced from a new supplier. Bentley will begin notifying owners on the same day. In Bentley's case, though, the automaker says "A hardware change will be required but the final solution is currently under investigation and cannot be confirmed at this time." Since the automaker moved to a new pump that isn't part of the recall population, we aren't sure why a resolution remains under investigation. Porsche owners can contact Porsche customer service at 800-767-7243 and refer to internal recall number APA1. Bentley owners can call 800-777-6923 and refer to RE23/02 (RC67). Anyone in that group can go straight to the National Highway Transportation Safety Administration at 888-327-4236 (TTY 1-800-424-9153) or nhtsa.gov, citing campaign number 23V033 for the Panamera or 23V034 for the Bentley.

Sunday Drive: A tale of old favorites and upcoming challengers

Sedans and crossovers dominated the attention of our readers last week, led by the completely redesigned 2018 Honda Accord. It's the Japanese automaker's flagship, and people are seriously interested in finding out how good the latest Accord is. So interested, in fact, that no other single story came close to the brand-new Accord in Autoblog reader interest. Moving down the list we find the equally new 2018 Buick Enclave. The three-row crossover has a lot to offer a family, especially one looking for a nice, quiet ride. If you're looking for the exact opposite of nice and quiet, but still want enough room for you and your significant others, the Subaru WRX that we tested last week may be the perfect ride for you. Or, if you just want to drive fast and aren't at all worried about space, there's the Camaro SS. See? We offer something for everybody. From there, we look to the future. Who isn't interested in seeing the first fully electric vehicle from Porsche? And who isn't intrigued to see the Mission E testing alongside a gaggle of Teslas? A brand-new Jeep is always a big deal, especially when it's the revival of a classic nameplate like the Grand Wagoneer. And finally, we have something completely different: the Rezvani Tank. As always, tune in to Autoblog next week for a front-row seat to all the happenings worth following in the automotive industry. 2018 Honda Accord First Drive | Feels like home again 2018 Buick Enclave First Drive Review | Fortress of quietude 2018 Subaru WRX Drivers' Notes | Turbo traditionalist 2018 Chevy Camaro SS Drivers' Notes | Demonstrative power, middling interior Porsche Mission E caught testing against Teslas Jeep three-row SUV caught on public roads — Grand Wagoneer, perhaps?
