Indeed, that is precisely what transpired. Mercedes retained the vehicle for around three months, substituted the high-voltage battery under warranty, and returned it to me without providing any clarification regarding the underlying failure. They replaced two buckled wheels when I indicated that a road test had evidently not been conducted.
I acknowledge that manufacturers frequently do not disclose internal reports; nonetheless, in this instance, the absence of information is especially concerning due to the vehicle's complete power failure, resulting in an immediate loss of both braking and steering assistance. Upon requesting clarification or simply fundamental confirmation of their beliefs regarding the events, I received no response.
Considering the gravity of the breakdown and its resultant crash, it is challenging to regard "no comment" as an adequate answer. I am want to ascertain if others have encountered a similar incident, as the lack of transparency from Mercedes renders it impossible to determine whether this was an isolated defect or a broader safety concern.
