Owners/service Manual problems of the 2014 Chevrolet Equinox

We have been having problems as have a few more with our 2014 chev Equinox lt 4 cyclinder motor when we drive on uneven, frost heaves, pot holes roads, any roads. The vehicle when flat towed behind a motorhome will start the "death wobble" I violently shakes the motorhome until we come to a complete stop and then we can start out again. It will do this at any speed. We are following the owners manual and proper hitch adjustments, the 4 cyclinder Equinox has electronic steering as opposed to the 6 cyclinder Equinox, that does not experience this problem, has hydraulic steering. Jeep had the same problem with the cherokee but the developed a wiring fix that powers the electronic power steering wien under tow, gm has yet to admit to the problem. The video I am sending is of a Jeep cherokee, but this is exactly what our 4 cyclinder 2014 Equinox does, as do many more owners say their 4 cyclinder Equinox's does. I had to include a date when this has happened, it has happened many more times than the one I had to put down, this was just the last time it happened. I have tried to send a video, cannot get it done, but if you go to youtube and type in seach, death wobble in Jeep cherokee towed behind motorhome and look at 2014 Jeep cherokee shaking violently while being towed you will see what is happening to our 4 cyclinder 2014 Chevrolet Equinox. This happens at any speed 10-60mph and it does not make a difference at what mileage it is. We bought the vehicle with 21184 miles on it, it now has 42555 miles on it.

2 days after purchase, heard a strange noise in car but unsure where it came from. Returned to dealer, problem couldn't be duplicated. I hear a strange thumping/beating sound periodically; heat exits vents while fan is off; several electrical? incidents, including; heater fan went off while driving on 29 degree winter day. It went back 1/2 hour later. (a few days prior, sounded like fan was losing power); digital speedometer on driver information center went off/blank for a minute while driving; phone charger (lighter & usb) outlet blew 2 fuses after using outlet for a few months with same charger & phone. Inconsistent depends which phone is being charged & charger used; ignition key got very hot after 45 min drive; dashboard lights (instrument cluster?) go dim when driving under a dark viaduct or tunnel, shouldn't they get brighter? manual doesn't explain how dic & instrument panel lights should operate. ); interior dome lights went on 2x on their own; infotainment system screen has a delay. Does not consistently display current song title & artist that is playing; digital temperature not consistently displayed on infotainment screen (new problem); oil life not reset after 1st oil change (caused confusion as to when to do next oil change. ); excessive water exiting tail pipe (told is normal). Service center where car was purchased checked car out on 4 different dates. No repairs done (except resetting oil life & replacing 2 fuses on charger), problems couldn't be duplicated. Went to another chevy service center, noted on paperwork "no problems found at this time", no other explanation given. Afterwards, I chatted with a rep @ chevy. Com, who filed a case & was told a service mgr will call in few days. It's been a few days, no call yet. I have 8200 miles & continue to feel unsafe, especially when driving with my 4 grandsons. They are reason I bought a new car!.
