Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While driving my gt350 on a highway at around 55 MPH the engine made metallic grinding noises suddenly, and without warning. I instinctively pressed in the clutch pedal and then engine stopped spinning and locked up. I was fortunate to be in an area with a pull-off area and thin traffic. It could have been very dangerous at higher speeds, in thicker traffic, or with a less experienced driver. Once stopped, I checked the car and confirmed that the starter could not spin the motor due to mechanical failure. There were only about 450 miles on the vehicle when this happened. …”

NHTSA complaint #11290162, filed 2019-12, 10,000 miles“Coolant intrusion into cylinder 2 at 26,000 miles. Was told by mechanic this is due to thin cylinder wall design between cylinder 2 and 3. And the thin coolant channel cut between them. A new engine block manufactured after 2020 was recommended because the engine design was changed to fix this issue. My warranty expired 4 months prior so I had to fix myself.”
