J.D. Power study sees new car dependability problems increase for first time since 1998

For the first time since 1998, J.D. Power and Associates says its data shows that the average number of problems per 100 cars has increased. The finding is the result of the firm's much-touted annual Vehicle Dependability Study, which charts incidents of problems in new vehicle purchases over three years from 41,000 respondents.
Looking at first-owner cars from the 2011 model year, the study found an average of 133 problems per 100 cars (PP100, for short), up 6 percent from 126 PP100 in last year's study, which covered 2010 model-year vehicles. Disturbingly, the bulk of the increase is being attributed to engine and transmission problems, with a 6 PP100 boost.
Interestingly, JDP notes that "the decline in quality is particularly acute for vehicles with four-cylinder engines, where problem levels increase by nearly 10 PP100." Its findings also noticed that large diesel engines also tended to be more problematic than most five- and six-cylinder engines.

Lexus GX 460 SUV gains technology on the road, and off of it

Lexus has updated its GX 460 SUV for 2020. The GX 460 is one of the longer-running SUV models on the market, as it was originally unveiled around a decade ago and it's still based on the sturdy Toyota Land Cruiser Prado, which is a touch more compact than the U.S. market Land Cruiser. The refresh gives the model some new touches to keep it in line with other current Lexus products, including a more contemporary spindle grille and new headlights, but it's restyled along the same moderate lines as the previous updates the GX 460 has received during its tenure. There are color and trim adjustments, including the addition of very red leather, but the powertrain remains the same: the 301-horsepower 4.6-liter V8 with 329 lb-ft or torque. But still, the ladder-frame GX 460 has off-road agility thanks to its Prado DNA, and those capabilities are now enhanced with a new Off-Road Package made available on the Luxury trim level. Cameras feed to multi-view and panoramic monitors to give the driver a better idea of the vehicle's surroundings off the beaten path, and Crawl Control and Multi-Terrain Select make it easier to handle the surfaces underneath the GX 460. Crawl Control keeps the vehicle progressing steadily in low range, also utilizing what Lexus calls "virtual" locking diffs. The GX 460's drivetrain comes with a Torsen limited slip differential, too. Multi-Terrain Select regulates wheelspin and can be automatically set to perform best in mud, sand, loose rocks or other driving surfaces. There's also downhill assist and hill-start assist as well as active traction control and vehicle stability control. As for on-road safety, Lexus has made its Safety System+ suite standard, and it comprises a Pre-Collision System together with pedestrian detection, lane departure alert, automatic high beam control and high-speed dynamic radar cruise control. Our test of the 2018 model lamented the lack of the latter in standard specification, but that matter has now been addressed. For on-road comfort, there's also the Kinetic Dynamic Suspension System, or KDSS, and an available adaptive variable suspension that has electronic control instead of just a fluid-based setup as in the KDSS. Any pricing adjustments have not yet been announced.

Lexus LC F prototype caught testing

The rumored Lexus LC F seems to be real based on these spy shots. A prototype was spied testing in Europe, and it shows a number of significant alterations from the regular LC 500 and LC 500h grand touring luxury coupes. In particularly, they seem to show a bit more of everything for the sporty edition. The nose bears some of the biggest changes compared with the standard models. While the center grille is mostly untouched, the outboard grilles have been cut wide open for more airflow. We can see the reason why, as there are heat exchangers in each of them. A particularly large one resides in the grille on the left side of the car. We can also see that the fenders have been extended over the wheel arches. Whether this is something to throw off observers or a final addition has yet to be seen, since the wheels and tires fitted to this car don't fill the added width, and the rear fenders aren't any wider, either. While nothing has changed to the sides of the car, we can spot the LC F's new brakes. They feature cross-drilled rotors and some beefy calipers. Moving around the back, we see that the LC F will get the signature stacked exhaust seen on the RC F and old IS F. Underneath, the tips will be matched with a wide diffuser that looks rather functional. Based on a previous report, it sounds like the LC F is still a couple of years away. Not much is known about the car, but it's safe to say it will make more than the 467 horsepower of the LC 500's naturally aspirated 5.0-liter V8. It could possibly have a twin-turbocharged 4.0-liter V8 or some sort of hybrid powertrain. To play in the same arena as some of the luxury performance competition, it will probably need at least 550 horsepower. Also expect it to cost significantly more than the LC 500h's low-$90,000s price tag. Related Video:
