Nissan, Kia under investigation over occupant detection systems

Kia and Nissan are facing separate investigations by the National Highway Traffic Safety Administration because of alleged problems with the occupant detection systems in their vehicles' airbags. The larger investigation is NHTSA's new engineering analysis into 986,826 Nissan and Infiniti vehicles. They include the 2013 Nissan NV200 and 2013-2014 Altima, Leaf, Pathfinder, and Sentra. Among the Infinitis, there are the 2013 JX35 and 2014 Q50 and QX60. Owners allege the occupant classification system can misidentify passengers and turn off the airbag if they don't weigh enough. Nissan recalled over a million vehicles worldwide last year to fix the same problem with a software update, but NHTSA kept getting complaints about the issue after the repair. The agency opened a preliminary evaluation in March, and after 1,271 complaints it has now been updated to an engineering analysis. The Feds intend to evaluate the effectiveness of Nissan's solution. NHTSA is also opening a preliminary evaluation into the 2007-2009 Kia Spectra for the occupant classification not working properly, and it could affect an estimated 186,000 of these vehicles. The government agency has 43 complaints from people allegedly reporting the failures. According to NHTSA, the issue could result in the airbag not deploying with enough force or not activating at all in an accident. This investigation is meant to assess the scope of the potential flaw, and there's no recall yet. INVESTIGATION Subject : Occupant Classification System Fault Date Investigation Opened: SEP 01, 2015 Date Investigation Closed: Open NHTSA Action Number: PE15031 Component(s): AIR BAGS All Products Associated with this Investigation Vehicle Make Model Model Year(s) KIA SPECTRA 2007-2009 Details Manufacturer: Kia Motors America SUMMARY: The Office of Defects Investigation (ODI) has received 43 complaints alleging a malfunction of the front passenger seat occupant classification system (OCS) in 2007-2009 Kia Spectra vehicles. The complaints report illumination of the SRS (air bag) warning light. All of the complaints allege the cause of the light illumination to be a malfunction of the OCS sensor mat imbedded in the passenger seat cushion, and/or report the presence of diagnostic trouble code B1448 which relates to the OCS sensor mat also. Many of the complaints note the malfunction occurred after the warranty period expired and mention high repair costs as a major deterrent to repairing the vehicle.

Eau Rouge Lite: Infiniti Q50 gets 400-hp, twin-turbo V6

The Infiniti Q50 Eau Rouge is still (probably) dead. But as consolation prizes go, a new 400-horsepower, twin-turbocharged V6 isn't bad. The 3.0-liter biturbo will be offered in two different states of tune. Enthusiasts will flock towards the aforementioned 400-hp model, but the first VR series engine will also be sold in a 300-hp version, as well. Regardless of output, both engines have a very broad torque curve, ranging from 1,600 to 5,200 rpm with either 350 or 295 pound-feet. A Mercedes-sourced, 2.0-liter, turbocharged four-cylinder will serve as the Q50's new base engine, matching the CLA250's 208 hp and 258 lb-ft of torque. The hybrid powered Q50 soldiers on, as do a line of standard seven-speed automatic transmissions. The naturally aspirated 3.7-liter V6 appears to be gone. Another big enhancement for the updated Q50 is a revised version of the widely disliked Direct Adaptive Steer system. Infiniti says its engineers "optimized the control logic to improve feedback from the road" – a huge area of complaint with the current steer-by-wire system. The Q50's new engine lineup will be showrooms later this winter. Read on for the official press release from Infiniti, and stay tuned for more from the brand – including the new Q60 Coupe – at the upcoming Detroit Auto Show.

The 3.0-liter V6 twin-turbo is an all-new engine from the new and exclusive VR- series powertrain family, born out of the brand's longstanding heritage of V6 powertrain production. The new engine has been engineered to empower the driver and offer increased power and torque and higher levels of efficiency than any comparable predecessors from the company.

2019 Autoblog Technology of the Year finalists revealed

Every fall, we line up a range of new models with the latest and most compelling automotive technology from the past year. We test everything from semi-autonomous systems like Tesla's Autopilot to trick suspension setups like the Multimatic spool-valve shocks on the Chevy Colorado ZR2. We spend months paring down the list to a small group of contenders. After testing, dinner and healthy debate, we tally up the votes and name our winner. For Autoblog's 2019 Technology of the Year Award, our three finalists are the Cadillac CT6 with Super Cruise, the Infiniti QX50 with Variable Compression Turbo and the Mercedes-AMG E 53 with EQ Boost. Super Cruise is an advanced SAE Level 2 semi-autonomous system, though Cadillac (unlike some of its rivals) is reluctant to push that point. Cadillac would like you to think of this as an advanced driver assistance feature rather than a semi-autonomous system. Super Cruise allows completely hands-free highway driving. Thanks to a driver-facing camera, the system forces the driver to keep his or her eyes on the road even if hands are off the wheel. Although the CT6 is being discontinued, look for Super Cruise to make its way to other Cadillacs soon. VC Turbo is a little more complicated. Basically, Infiniti's 2.0-liter turbocharged inline-four can vary the compression ratio on the fly. In general, turbocharged engines are more efficient than naturally-aspirated engines when on boost, but can perform worse at low revs. VC Turbo allows for a best-of-both-worlds situation, increasing the compression at low revs and backing it off once the turbo spools up. The best part is that it does so seamlessly, with only a dash readout letting you know what's going on under the hood. Our third finalist is the EQ Boost 48-volt system in the Mercedes-AMG E 53. Like VC Turbo, EQ Boost does a lot just beneath the surface. Mercedes has developed a new turbocharged 3.0-liter inline-six and paired it with a small electric motor. While the car can't run on electricity alone, the motor helps improve both efficiency and performance, smoothing shifts and filling in low-end torque before the turbos spool up. Think torque fill, similar to a McLaren P1. Who can complain about better fuel economy and more torque? Look for the 48-volt system to make its way into most of the Mercedes-Benz lineup. The winner will be revealed next week on Autoblog, and we'll present the award Jan. 15 at the Detroit Auto Show. Related Video:
