What owners reported
Source: NHTSA complaint databaseOwners of the 6 model years this bulletin names have filed 916 complaints with NHTSA since 2015. 154 of them name Electrical System, Fuel/Propulsion System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
There is a recall on my 2020 Acura MDX and I have been going to the local Acura dealer to get the part for the last 6 months and every time I go they tell me they are still waiting for the part. Periodically, the vehicle lurches while I am driving causing a major back and forth tugging and jerking. This is very unsafe.
