Ford recalls nearly 200,000 Expeditions and Navigators for fire risk

Ford is recalling 2015-2017 Expeditions and 2015-2017 Lincoln Navigators because the front blower motor could fail and cause a fire. In total, 198,482 Expeditions and Navigators will be recalled. In the official recall documents posted by NHTSA, Ford says that it “has not identified the cause of this condition.” However, Ford also says it is currently aware of 25 fire allegations related to the blower motors on these vehicles. Despite not strictly identifying the cause of blower motor fires, Ford put forth a theory in its fieldwork analysis of the issue.  “In June 2022, based on component analysis, Ford Engineering theorized that a mispositioned blower motor brush holder spring could cause an internal short or localized heating of the brush spring or holder. It is believed that when a fire initiates on the blower motor, it does so at the positive brush holder location. The variable blower controller would remain operational and there would be no signs of an overheated relay. Field data indicates that this concern typically occurs at a higher time in service, and on vehicles with higher mileage.” Since the blower motor is located on the passenger side interior behind the glovebox, the fires that start are interior fires. Ford isnÂ’t aware of any accidents related to this issue, but there is one claim of burnt hands and fingers as a result of a fire. According to Ford, warning signs of an impending fire or failed blower motor include an inoperative fan, burning smell and/or smoke from the instrument panel vents while the vehicle is on. To remedy this situation, Ford is recalling the affected SUVs and replacing the blower motor assembly with a revised part. The new part uses a blower motor assembly design utilized on other applications. If folks with these SUVs experience any symptoms of blower motor failure before the new part becomes available, Ford says they can take their vehicle to the dealer to have it replaced with a part of the same design. Once the redesigned part becomes available, the dealer will then swap it in. Owner notification letters are expected to begin on September 12 this year.

The tricky business of octane, power, and MPG

Given tepid green-car sales numbers this year, consumers in the US aren't making the transition away from internal combustion engines too quickly. Regulations are still mandating cleaner emissions, though. In addition to downsizing and turbocharging, there's growing consideration about moving to higher-octane fuel to improve overall efficiency. In a new report, engineers at FCA, Ford and General Motors Powertrain are showing that it could work, too. The major advantage to higher-octane fuel is that it supports higher compression ratios. That in turn can lead to more power from burning the same amount of gas. "Higher ethanol content is one available option for increasing the octane ratings of gasoline and would provide additional engine efficiency benefits for part and full load operation," the researchers write in the study's abstract. The authors even think it could be possible to update some modern vehicles' engine calibration to be optimized for the better gas. While the benefits are there, we still have a long way to go before higher-octane fuel becomes a national standard. According to Green Car Congress, 87 percent of the gas sold in the US is regular grade 87-octane. Meanwhile, premium 91-93 octane makes up just 10 percent. The various grades of fuel illuminate even more annoyances with the current system. For example, Ford generally recommends 93-octane for EcoBoost engines, and the power outputs that the company publishes are based on using it. However according to Green Car Reports, such premium gas is very difficult to find in some regions of the US, especially along the West Coast. The powertrains still run on lesser grades but with lower power output. The researchers' discussion of possibly increasing ethanol in gas also comes during a heated debate on the substance. The current administration is pushing for less of the corn-based fuel in the coming years. Although, several presidential hopefuls might be favor of reversing that course.

Ford calling in 28k Edge crossovers over fuel line leak

A problem with the fuel line on certain examples of the Ford Edge has prompted the National Highway Traffic Safety Administration to issue a recall. The issue revolves around the metal housing on the fuel line pulse damper, which was apparently improperly manufactured in the first place and is prone to crack in certain circumstances, leading to a fuel leak. And as we all know, a fuel leak is not a good thing.
The problem affects model year 2012 and 2013 Edge crossovers equipped with the 2.0-liter engine and manufactured between September 2, 2010 and April 25, 2013 - a total of 27,933 units. Although the Lincoln MKX is closely related to the Edge, since it isn't offered with the same engine (to which the problem is related), the recall does not include the premium-badged version. See the recall notice below for further details.
