NHTSA Complaint #11594748 — 2018 ALFA ROMEO STELVIO

I was in the process of merging on the the express way when my vehicle threw a warning light, "service electronic throttle control" along with a "service engine" message and a check engine light. The vehicle went into a "limp" and had extremely poor acceleration, I was almost rear ended because the vehicle couldn't reach highways speeds fast enough. The vehicle has not yet been inspected my the manufacturer but I did some research on this issue and found it to be alarmingly common. There seems to be no clear answer to the reason for this and no sure repairs for the problem. This poses a safety risk to drivers as this problem seems to happen while accelerating. It can be dangerous if someone on the expressway is attempting to merge into 60mph traffic and hit "limp mode" at roughly 30. I believe an investigation need to be conducted regarding this followed by a recall of the affected part.
