A recent software update was not successful. Your vehicle cannot be driven
A viral photo of a Ford EV displaying “A recent software update was not successful. Your vehicle cannot be driven” has reignited worries about how over-the-air updates can effectively brick modern cars. Commenters contrast Ford’s apparent lack of robust fail‑safes with practices like dual firmware partitions, strict partitioning between critical and noncritical systems, and more conservative update processes used in other embedded domains. The incident feeds into a broader backlash against highly connected, software‑heavy vehicles, with some arguing for “dumb” or minimally networked cars while others stress that safety features and diagnostics now depend on complex software that must be made more reliable, not abandoned.
Incident and Affected Vehicle
- Screenshot shows an in-car message after a failed software update stating the vehicle cannot be driven and giving instructions “for the tow truck operator,” which many find alarming.
- Multiple commenters identify it as a Ford EV, most likely a Mustang Mach‑E or possibly an F‑150 Lightning, supported by interior photos and “Ford Customer Relationship Center” text.
- An earlier forum post with the same error is referenced; the original owner discussion is linked on a Mach‑E subreddit.
Software Update Design & Fail‑safes
- Many argue bricking a car via update is inexcusable and that automotive software should use A/B (dual) firmware partitions, rollback, and limp‑home modes, as is common in routers, Android, TiVo, etc.
- Others note modern cars have dozens or hundreds of microcontrollers, some with limited flash, making full dual‑image schemes harder and distributed updates more complex.
- Several describe robust dual‑boot or recovery schemes they’ve implemented in other embedded systems and are surprised an automaker didn’t match that bar.
- Possible root causes discussed include out‑of‑disk or out‑of‑memory conditions and failing sub‑modules, but the specific failure here is unclear.
Connected Cars, OTA Updates, and Ownership
- Some participants dislike internet‑connected, remotely updateable cars on principle, citing loss of reliability, control, and the risk of remote bricking or privacy abuse.
- Others defend connectivity for conveniences like remote preheating, charge monitoring, and live maps, arguing the market has moved and connectivity is here to stay.
- Middle‑ground views favor strict partitioning: critical driving systems should remain operable even if infotainment or comfort features fail or mis‑update.
Desire for “Dumb” or Simpler Cars
- Strong nostalgia for “dumb” or minimally computerized cars, especially older models that are easy to repair and not networked.
- Counterarguments highlight benefits of modern electronics: safety systems (ABS, airbags, sensors), higher efficiency, easier diagnostics (OBD2), and reduced wiring via CAN bus.
- Some suggest keeping a simple ICE car as a backup alongside a feature‑rich EV.
EVs, Brands, and Software Competence
- Debate over which manufacturers handle software best; Tesla is cited both as a positive example (isolation between infotainment and drive systems, non‑destructive updates) and a negative one (past bricking incidents, EMMC wear‑out, quirky features).
- Thread emphasizes that these issues are not EV‑specific; similar failures and OTA complexity affect modern ICE vehicles as well.
Engineering, Process, and Regulation
- Discussion about software vs mechanical engineering rigor: cars mechanically can’t “have their fronts fall off,” but software failures often face weaker regulation.
- Some call for regulatory oversight of automotive software updates or at least strong process rules and audits, especially for anything safety‑related.
