I saw this a while ago, and I assumed that someone would give you an answer, but it doesn't
look like anyone will. So I'll make an attempt. 
As Ulrich suggests, it is  better to stick to
normal varieties, so your nodal/cuspidal curves are immediately eliminated. So we should move to dimension at least two. 

A very simple class of examples are cones. Let $V\subset \mathbb{P}^N$ be a nontrivial smooth variety, 
and let $R$ be the local ring of the vertex of the cone over $V$. This is normal and $\dim R\ge 2$. $R$ (or $Spec R$) is $\mathbb{Q}$-factorial exactly 
when $Cl(R)\otimes\mathbb{Q}=0$ where $Cl(R)$ is  the (Weil) divisor class group. Now
according to Lipman "Unique factorization in complete local rings", Alg. Geom, Arcata (1974)
$$Cl(R)= Cl(V)/\langle\text{hyperplane}\rangle$$
>Thus $R$ is $\mathbb{Q}$-factorial if and only  if the 
$Cl(\mathbb{P}^N)\otimes \mathbb{Q}\to Cl(V)\otimes \mathbb{Q}$ is surjective. 

This is generally *not* true. For example, if $V$ is a curve, $R$ is $\mathbb{Q}$-factorial if and only if $V$ has genus $0$. [**Added Note**: I mean that a cone over a higher genus
curve $V$  *cannot* be $\mathbb{Q}$-factorial because $\dim Cl(V)\otimes \mathbb{Q}=\infty$
in this case.]
