Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“When cold the cv transmission in the IQ will not allow the vehicle to pull away up a steep hill. This has happened several times and represents a serious safety concern. The issue only happens when the car is cold, it will pull the same hill with no problem when warm. The IQ has a cv transmission and it fails to adjust to a high enough RPM to pull away up a steep (10%) grade. The problem manifests as either no or very slow forward progress (less than walking speed) even with the accelerator hard down. The dealership service rep seemed unconcerned about the issue.”
