I have a new 2015 Trailhawk with stop-start and 4:08 gearing. It has 1500 miles on the clock. I love this vehicle, but I have noticed a few issues and wondered if anyone has seen the same issues.
1) radio changes from FM to AM within the first 30 seconds of starting the engine. This happens when still in park, no hands on the wheel, just me in the seat and looking at my cell phone. Never happens again with key on.
2) NO 9th gear EVER.. ( I have tried fast, slow, up hill, down hill, cruse on, cruse off, manual shifting and in "D")
3) NO 8th gear when the cruse is ON, it just hums along in 7th for mile after mile at about 2250rpm @ 70 MPH [MPG at 19 on flat ground]
4) With cruse OFF, I can get 8th gear on flat ground, 70 mph, but I must tip into the throttle, then let off to get it to shift. It will hold 8th till the slightest incline then back to 7th. [8th shows about 1850 RPM and 24 MPG]
5) At highway speed, with 4x4 set to AUTO .. I get a LOUD nosy rumble with noticeable vibration in the rear of the vehicle when a) move the shifter left from "D" to manual. [OR] b) hit the traction control button. I suspect the rear axle kicks on, but why?
Note: 1st through 7th gear shift fine, but as other have mentioned, I have noticed a "speed up" feeling when it down shifts.
I have not talked to the dealer yet, but I will visit in the next week or two.
Any input will be appreciated. Thanks for looking...
