Subaru Recalls the Solterra Again for Potentially Loosening Hub Bolts

The Subaru Solterra and the related Toyota bZ4X faced recalls last year related to their hub bolts. The automakers discovered that they could loosen while driving, causing the wheel to detach from the vehicle. Though the vehicles were fixed under the recall, Subaru recently issued another recall to ensure the original work was done properly. 

Subaru said the recall covers Solterras that were fixed at two port processing facilities by a third-party company. The contractor did not properly complete the repair procedure, which could result in under-torqued bolts. 

Though the affected Solterra population is limited to the two port locations Subaru identified, it said it is recalling all models repaired by the third-party company, regardless of the location. Vehicles repaired by other facilities are not included. Subaru only sold 919 Solterras in 2022, so this recall involves all of those, plus some. 

Unfortunately, this means affected owners won’t be able to drive their vehicles. The recall states, “until the inspection/remedy is completed, customers will be instructed not to drive their vehicle and to make arrangements with their Subaru dealer to have the vehicle towed for inspection. Towing will be offered at no cost to the customer. Subaru estimates that all potentially affected vehicles are still under the original warranty, but if there are any exceptions, Subaru will provide reimbursement to owners for repairs according to the general plan submitted in May 2022.”

    I have been curious about this before and didn't find anything but was curious just now and found this diagram. They are bolts which go through the wheel into the hub, instead of lug nuts going onto studs. Who knew (not me).

    And apparently " wheel hanger stud" is a thing, because the wheel (and tire) is not going to support itself while you conduct a blind search for the bolt hole, is it? 😉

    And here is the background/detail from Toyota.

    Why not use a 'reverse thread' like Chrysler used for a while in the late 1960's or early 1970's?

      Late '50s Thunderbirds also (a neighbor had one and the left-hand threads confused him a bit). Many large over the road highway buses also utilize left-hand threads on the US driver's side wheels.

    By the way, on a related note, it looks like the class action against Subaru regarding batteries got final approval on January 24th, in case anyone here is impacted.
