GM's ecomodding efforts leads to recall of Cobalt (electric power steering probs)

Some of you are already aware of this...



Quote:
General Motors announced it would recall 1.3 million Chevrolet Cobalts and Pontiac G5s built between 2005 and 2010. GM will replace the motors on their electric power assisted steering (EPAS). Over time the motors can reportedly fail and lead to a loss of steering assist.

(EDIT: note I highlighted the word "assist" above - when the e-motor stops, you still have manual steering.)

You can be pretty sure GM only put the electric pumps in the cars as a fuel saving measure.

It does make me wonder how many other reliability issues we might see as auto makers embrace less mature technologies in an effort to improve efficiency.

Maybe the thought is unwarranted - electric motors don't usually have reliability issues (not like they're an immature technology). More likely a production process or materials issue from a supplier.
