2011 Enclave Sensor issue??

[Stotler81]

Recently my wife’s 2011 Enclave has (while driving) been having some sort of issue. It doesn’t happen every time, sometimes can drive around all day and it never happens. But sometimes while driving the RPM and Speedometer gauges just kind of stop working and maybe bounce up and down from zero to whatever, she gets a bunch of stuff turning on and off like the Traction’s Control will show up on the dash and keep turning on and off on its own. Before we have shut the car off waited a minute and turned it back on and it will go away for awhile. However once it continued a couple times and eventually stopped after turning the car off for the second of third time in a matter of a few minutes. The other day we had it happen and when we went to put the car in drive it would not move. Speedometer and RPm gauge were moving accordingly but the vehicle had no movement forward in drive. It would however go in reverse. Took to dealership only for them to tell us it was operating as it should. Clearly not. Possible word could be some sensors in the transmission?

Could be the wheel speed sensors or the harness going to them that is constantly flexing could of developed a intermittent break.

When the wheel speed sensors fail, so does the traction control and ABS because they are dependent on th speed reading of the wheels.

There is a little piece that goes into the bottom of the transmission and it’s apart of the arm axles can’t remember the name but it may have fallen out
