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.

Volvo calls in S60 T5 over oil pressure indicator

As anyone with a driver's license should be able to tell you, the oil pressure indicator on a car is a vital feature. If you don't have enough oil pressure, your engine could seize up, leaving you stranded and causing catastrophic damage for both your automobile and your wallet. Worryingly, then, the National Highway Traffic Safety Administration says that the oil pressure indicator lamp on certain Volvo S60 models is prone to failure, prompting the manufacturer to issue a recall.
The issue pertains to MY2011-2012 Volvo S60s with turbocharged five-cylinder engines manufactured between June 22, 2010 and May 14, 2012. All told, precisely 30,929 units are affected by the recall campaign. The owners of affected models will be notified by Volvo to bring in their cars to their local dealer for a software update. See the official notice below for details.

Volvo XC90 Coasting Transmission Deep Dive | How, when and why of coasting

In our recent 2021 Volvo XC90 Recharge review, its turbocharged-supercharged-hybridized powertrain delivered impressive horsepower and fuel economy. But Volvo has one additional trick up its sleeve, propelling a car with power that's simpler, cheaper and all-natural: It's the power of momentum and gravity. I've always been halfway to a hypermiler. I'm not obsessive about it, but in city driving, I enjoy timing stoplight approaches to keep the wheels rolling and avoid the inertia of restarting from a stop. There's little point to needlessly racing and braking between red lights, wasting kinetic energy (and therefore fuel). So I tend to drive strategically instead, often catching up with the drivers who jackrabbit but get hung up at the lights. And, back when I owned a long line of vehicles with manual transmissions, I coasted. Coasting used to be slightly controversial. Some claimed it doesn't actually save gas, though my mileage calculations showed otherwise. Another school of thought insisted that removing engine braking from the equation, even momentarily, constitutes a dangerous loss of control. Of course, an experienced driver can slip a manual transmission back into gear in a flash when engine braking's actually needed. And one should always use some common sense and judgment about when and where to coast. I'm not talking about careening down a 15% grade into a school zone.  Anyway, those arguments became moot when automatic transmissions pretty much took over. (And no, never coast with a typical automatic transmission. Even if it weren't damaging to your type of automatic — but assume that it is — the risk of screwing up a nudge of the shifter from drive into neutral is too great.)

Volvo calls the feature on its Aisin eight-speed "Eco Coast." Some Mercedes, BMWs and others call it "sailing" or "gliding." The Hyundai Ioniq, Ford Mustang Mach-E and Polestar 2 are among EVs that allow you to cancel out all regeneration and freewheel downhill. And future cars such as the BMW iX are also being designed to do it. By building coasting into the clockworks, automakers have taken any traffic safety concerns out of the question, because the car will instantly switch you back into gear when needed.
