Lexus tops JD Power Vehicle Dependability Study again, Buick bests Toyota

It shouldn't surprise anyone, but Lexus has once again taken the top spot in JD Power's Vehicle Dependability Study. That'd be the Japanese luxury brand's fourth straight year at the top of table. The big news, though, is the rise of Buick. General Motor's near-premium brand beat out Toyota to take second place, with 110 problems per 100 vehicles compared to Toyota's 111 problems. Lexus owners only reported 89 problems per 100 vehicles. Besides Buick's three-position jump, Scion enjoyed a major improvement, jumping 13 positions from 2014. Ram and Mitsubishi made big gains, as well, moving up 11 and 10 positions, respectively. In terms of individual segments, GM and Toyota both excelled, taking home seven segment awards each. The study wasn't good news for all involved, though. A number of popular automakers finished below the industry average of 147 problems per 100 vehicles, including Subaru, (157PP100), Volkswagen (165PP100), Ford/Hyundai (188PP100 each) and Mini (193PP100). The biggest losers (by a tremendous margin, we might add) were Land Rover and Fiat, recording 258 and 273 problems per 100 vehicles. The next closest brand was Jeep, with 197PP100. While the Vehicle Dependability Study uses the same measurement system as the Initial Quality Survey, the two metrics analyze very different things. The VDS looks at problems experienced by original owners of model year 2012 vehicles over the past 12 months, while the oft-quoted IQS focuses on problems in the first 90 days of new-vehicle ownership. Like the IQS, though, the VDS has a rather broad definition of what a problem is. Because of that, a low score from JD Power is no guarantee of extreme unreliability, so much as just poor design. In this most recent study, the two most reported problems focused on Bluetooth connectivity and the voice-command systems. The former leaves plenty of room for user error due to poor design (particularly true of the Bluetooth systems on the low-scoring Fords, Volkswagens and Subarus), while the second is something JD Power has already confirmed as being universally terrible. That makes means that while these studies are important, they shouldn't be taken as gospel when it comes to automotive reliability.

Stellantis aims to eliminate separate inverter, charger to improve EV efficiency

Stellantis has announced that, in collaboration with French battery company Saft and French National Center for Scientific Research, has made significant progress in eliminating two major components of an electric vehicle powertrain: the on-board charger and the power inverter for the motor. The company claims that doing this will allow for better space use in vehicles, as well as improvements in efficiency, cost and reliability of components. As a quick primer, also explained in the below video, the on-board charger and power inverter are sort of translators to get the right current to different parts of the electric powertrain. The on-board charger takes AC power from the grid and converts it to DC to charge the batteries. Then when power goes from the batteries to the electric motor, the power inverter converts that DC power back to AC. These components aren't exactly small. Frequently you'll find them packaged somewhere under the hood. What Stellantis and its cohorts have developed, and have been using on a test vehicle since last summer, are small power inverter boards that can be mounted very closely to the battery packs. They can handle both conversion needs, for charging and discharging, instead of needing two separate devices. The most obvious perk to this is that you can do away with those traditional components and free up more space, either for making smaller vehicles without losing interior volume, or adding space to a vehicle that wouldn't have had it otherwise. There's the additional benefit of reduced weight, something that EVs struggle with. Stellantis also claims improvements in efficiency, reliability, and cost, however, it didn't go into detail as to how this setup would do that exactly. We'll try to get in touch with representatives from Stellantis in order to get more information. We're still a ways out from seeing this technology in production Stellantis vehicles. The company said it aims to apply it to vehicles by the end of the decade. Saft is also looking at using it on stationary battery systems as well. So maybe we'll see it on a 2029 Ram 1500 REV, but for now, we'll be living with traditional chargers and inverters. Related Video: Green Alfa Romeo Chrysler Dodge Fiat RAM Technology Electric

Enter here to win the 2021 Ram TRX, the fastest pickup on the market

Autoblog may receive a share from purchases made via links on this page. Pricing and availability is subject to change. No donation or payment necessary to enter or win this sweepstakes. See official rules on Omaze. For years the Ford Raptor stood alone, on top of the off-road pickup truck mountain, hardly challenged by the competition. Finally, a new challenger has emerged, the 702 horsepower Ram TRX. The problem? A price tag that will make you blush. Unless you win one from Omaze. Win a RAM 1500 TRX and $20,000 - Enter at Omaze Here’s what we said about it in our Ram TRX First Drive Review: “Looking over the spec sheet of the 2021 Ram 1500 TRX, itÂ’s hard not to think America has hit peak pickup truck. Everything about the TRX is bigger, better and badder than any truck thatÂ’s come before, including its one obvious bogey, the Ford F-150 Raptor. For starters, the Ram has a 252-horsepower and 140-pound-foot advantage on the Ford. That means the TRX is quicker and faster, and it can haul and tow marginally more. The TRX has a nicer interior and its supercharged V8 engine sounds a heck of a lot better than the RaptorÂ’s turbocharged V6. Altogether, that ought to equal a truck thatÂ’s more fun to drive." “More important than the muscular styling is what that bodywork encases, starting with a frame that Ram says shares just 25% with lesser 1500s. ItÂ’s designed to be stiff and durable enough to withstand off-road terrain at speeds of 100 mph. The TRX boasts 11.8 inches of ground clearance, and can ford water up to 32 inches deep. Bilstein Black Hawk e2 adaptive shocks with nitrogen-charged remote reservoirs continuously adjust to handle current demands, whether that means taking the edge off a bumpy road or absorbing much larger impacts, like when landing a jump. There's 13 inches of wheel travel up front and 14 inches out back, allowing for a huge amount of articulation.”  YouÂ’re probably asking yourself, what does it take to win? First of all, according to Omaze, "no donation or payment is necessary to enter or win this sweepstakes." $10 will get you 100 entries in this giveaway, while $50 will get you 1,000 entries and $100 will get you 2,000 entries. The donations themselves benefit Team Rubicon. According to Omaze, “Team Rubicon is a veteran-led disaster response organization that mobilizes veterans, first responders and civilian volunteers to help communities before, during and after disasters and humanitarian crises.
