Volvo recalls 27,457 new vehicles over a brake-by-wire issue

Eight Volvos from the 2023 model year have been drawn into a recall over software in their brake-by-wire systems. The models at issue are everything Volvo sells — the C40, XC40, S60, XC60, V60, V60 Cross Country, V90 Cross Country, and XC90. The combined recall population numbers 27,457 cars. The problem is that an in-vehicle diagnostic test to check the grounding of the system can trigger a fault in the vehicle's Brake Control Module 2. The fault doesn't always occur, but when it does, the vehicle reverts to its hydraulic system so the car can still stop. However, without the brake-by-wire system, the driver doesn't get the benefit of software-defined safety systems like ABS, ESC, Traction Control as well as convenience features like Pilot Assist, adaptive cruise control and one-pedal driving. Drivers might be alerted to the situation with a warning message and malfunction lamp in the gauge cluster, or a stiff brake pedal. The automaker says it has had no reports of accidents, injuries or fatalities because of the problem. If the car is turned off and able to enter what Volvo calls "deep sleep," the electronics will clear the fault. To fix the issue, Volvo will send an over-the-air update with logic that's a better fit for the Brake Control Module 2 hardware. The automaker says the new code "will be implemented on February 20" of this year, but in another example of the digital world outpacing regulatory processes, Volvo will begin notifying owners on March 15.

Cadillac tops Tesla in Consumer Reports semi-automated driving test

General Motors' Cadillac outscored Tesla in a new ranking of partially automated driving systems tested by Consumer Reports and released on Thursday. The highly influential nonprofit organization, which tests and rates a variety of consumer products from appliances to vehicles, said it compared Cadillac's Super Cruise and Tesla's Autopilot with similar systems from Nissan and Volvo. Nissan's ProPilot Assist was ranked third and Volvo's Pilot Assist fourth. Consumer Reports said it has been testing partially automated driving systems for several years but elected to conduct a formal study intended for publication, because "we are at a tipping point where they are now going mainstream," according to Jake Fisher, director of auto testing. The organization said its tests, conducted on a private track and on public roads in Connecticut, were designed to measure the systems' ability to automatically control steering and speed in certain situations, while helping drivers pay attention and regain manual control of the vehicle when required. CR noted that any of these systems can increase driving risk if used in inappropriate situations, or if drivers become inattentive or over-reliant on them. While they can help relieve driver stress and fatigue, Consumer Reports said, the partially automated systems are "not intended to be self-driving features." The systems typically use cameras, radar and other sensors, as well as mapping data, to monitor location and traffic conditions and help keep a vehicle centered in the lane at a safe distance behind other cars. Each system has limitations. Cadillac's Super Cruise, for instance, only functions on divided highways that have been mapped by GM. In contrast, Tesla's Autopilot can be used even on small, curvy roads with poor lane markings, but "operates erratically in those situations," Consumer Reports said.The organization tested Super Cruise on the Cadillac CT6; Autopilot on the Tesla Model 3, Model X and Model S; ProPilot Assist on the Nissan Leaf and Infiniti QX50; and Pilot Assist on the Volvo XC40 and XC60. Consumer Reports said Cadillac's Super Cruise did "the best job of balancing high-tech capabilities with ensuring the car is operated safely and the driver is paying attention." Tesla's Autopilot was cited for its capability and ease of use, while Nissan's ProPilot Assist did a better job than Autopilot or Volvo's Pilot Assist in keeping drivers engaged.

Volvo and Polestar Range Assistant app promises more range for EVs

Volvo and Polestar just released a new app for their EVs that promises to help optimize driving range. It’s called “Range Assistant,” and itÂ’s coming as an over-the-air update to the Volvo XC40 Recharge and Polestar 2. The Volvo C40 Recharge will have it built into the car from the factory. ItÂ’s exclusive to EVs and Volvo/Polestar products running the Android Automotive infotainment system. Volvo says the app has a range-optimizer functionality that automatically adjusts the climate control to improve range. ItÂ’ll also coach drivers with driving style and speed recommendations to increase range on longer trips. The app also comes with passive forms of range improvements. Volvo claims itÂ’ll help better manage battery and regeneration performance. Plus, it has a “smarter timer to precondition the batteries.” For example, when you input a charging destination into Google Maps, the car will automatically precondition the batteries to be ready for maximum charging speed by the time you arrive. ThereÂ’s more data for the driver to scan, too, as Volvo provides greater detail on the available range and real-time energy consumption. Volvo doesnÂ’t put a number or percentage on the range increase that drivers may experience with this new app, but does claim that range will go up because of it. In addition to the new app, Volvo says this latest OTA update includes “further improvements on the safety systems, new information about cold climate impact on battery range and various bug fixes.”  The app is scheduled to be rolled out to the applicable vehicles by the end of October. Its functionality will come baked into the complimentary four-year Volvo Care Package that all Volvo EVs automatically get. Of course, after those four years, youÂ’ll be on the hook for the data connection cost and package fee. Note that the Range Assistant appears to be tied up into this package, and while it wonÂ’t incur a separate fee, youÂ’ll need it and the data connection to take advantage of it after so many years.
