What Owners Say
"described in previous answer"
Anonymous, NJ (2017 GMC Acadia SLE 3.6-L V6)"Thermostat. I noticed the fan(s) continued to run at high speed when stopped. Gauges were off."
Anonymous, TX (2017 GMC Acadia Denali 3.6-L V6)"Very, very poor forward visibility for the driver. Blocked by both window frames & the outside front mirrors. The problem is big enough to hide/block the driver's view of 2 close-in adults in a crosswalk, etc. The throttle pedal is much too light and you can easily overdo acceleration. The steering is too light and tight. A slight, unintended movement can cause somewhat disturbing directional change."
Anonymous, CA (2017 GMC Acadia SLT 3.6-L V6)"Water pump system etc. very expensive!!!!"
