Moody's –  which ranks the creditworthiness of corporate borrowers – has downgraded Nissan's to "junk,"  reports Reuters. Senior analyst Dean Enjo cited "risks associated with the implementation of its new restructuring plan, the renewal of its aging product range and global trade policies" as the main reasons for the downgrading, as well as the probability of "negative cash flow" for the rest of this year.

In sum, it does not look good for Nissan. But it isn't as bad as it is for Chrysler and Dodge. Or VW, for that matter. 

Chrysler is in worse shape than Pontiac was back in 2010, the final year for that brand – because there's only one 2025 Chrysler, the Pacifica minivan. And sales of that one model declined to just 59,273 examples last year from 73,845 the previous year. The year before Pontiac went to that great boneyard in the sky, it sold 87,171 G6s – which were the last new Pontiacs sold before the end came the following year. Pontiac also had a full lineup of other models before that final year (2010) including the G3, G5 and G8 as well as the Solstice sports car and the Torrent and Vibe crossovers.
