I have an AWD 2.0 2016 Tucson. I am noticing that it seems that the RPM's are high. Looks like driving at 65 mph RPM is about 2300-2500. Is this normal? I brought this to the attention of the dealer service and he claims that this is fine. I have another Tucson and Ford pick up and the RPM are never that high. Any input would be appreciated.
