[R-sig-ME] with lmer : Erreur dans names(argNew)[1] <- names(formals(new))[[1]]

[Douglas Bates]

Without a reproducible example it is difficult to determine why the
problem may be manifesting itself.  I would note that you are using
the car package and there may be an interaction between having car
loaded and some of the methods in lme4.  However, without a
reproducible example and some information on exactly what versions of
which packages are attached (i.e. the output from sessionInfo()) this
is just speculation.
