Car and Driver currently has a 2014 C7 in its long-term test garage, and while the rag has given the sports car high marks for its good looks and excellent driving dynamics, it has given them one major fit – a blown engine.
According to Car and Driver, the engine in their long-term Stingray went kaput after just 6,000 miles. General Motors is still investigating the matter, but has initially concluded that the engine failure was the result of a faulty oil filter that let loose metal debris into the engine. The metal flakes worked their way through the system, ultimately damaging a connecting-rod bearing and the entire bottom end of the LT1 engine.
Moreover, Car and Driver suggests that the engine fault that brought down their C7 is more of a widespread issue rather than an isolated incident.
“We’ve heard of a few similar accounts throughout the Stingray community and GM says it’s aware of the issue and is analyzing its manufacturing process for a root cause.”
We’ve reached out to GM for comment on the matter but so far haven’t heard back. We’ll be sure to update this space when new information becomes available.
