Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While driving at highway speeds with the adaptive cruise control engaged, the vehicle detects vehicles to the right (same direction of travel) or at times vehicles to the left (opposite direction of travel) and abruptly applied backing. No vehicles will actually be in lane of travel of the vehicle to cause action. On a 87 mile drive (one way to work) happens more than eight times on first drive and over ten time on second drive. Vehicle has under 1500 miles on it and was purchased brand new. Taken to Acura and told to turn off lane departure system unless in city traffic. …”
NHTSA complaint #11387623, filed 2021-01, 1,420 miles“upon turning right, the car lost power, degraded acceleration as if someone is holding and pulling the car to move forward. The traffic behind me expected me to cathup with the speed on the road but due to loss of power and engine hesitation i got honked and was luck to avoid a crash from behind on a busy road. Acura dealership in Dallas dont have parts since a very long time. They have pleant of new cars to sell but not repair.”
