Hi All,
A couple of months ago I noticed that my air suspension on my '14 Overland Diesel was dropping into aero mode when I was merging onto the highway around 55 MPH. The OM states "The vehicle will automatically enter Aero Mode when the vehicle speed remains between 62 mph (99 km/h) and 66 mph (106 km/h) for greater than 20 seconds or if the vehicle speed exceeds 66 mph (106 km/h)."
I tested my theory a few times by setting the cruise control to 57 MPH while merging onto the highway in both ECO mode, and with ECO turned off, and as I suspected the suspension had dropped to aero as soon as it hit 56/57 mph in either case.
I assumed maybe the software was off, but I just took my car in for its first service three days ago and when I asked the service manager and technician, they both stated that the suspension was operating normally and the speeds listed in the OM must be a mis-print, which I find suspicious. They actually went as far as to state on my service paperwork that the OM was mis-printed.
The only reasons this truly bothers me is that #1. I like things to work properly as described, and #2. on my daily commute, traffic can have you varying from 60 mph to 20 mph and back multiple times over my 12 mile trip. Having the suspension constantly cycling up and down is not ideal and fairly annoying and this would not occur for the most part at the speeds listed in the OM. Yes, I realize I can drop into Sport mode and remain in aero the entire time as a partial solution, but as many of you know that's a trade-off as well in terms of fuel economy and shift patterns while in traffic.
So long story short, has anyone noticed this issue? And does anyone know if the OM is in fact wrong? Or was there possibly a software update or TSB that possibly adjusted the speeds since the OM was issued? I can certainly see merit in having aero mode engage over 50 mph, but as I mentioned above I prefer to know things are working as they should on a brand new vehicle so any feedback is greatly appreciated.
Thanks as always and look forward to hearing back.
