ESC TSA REDUCED BRAKING ASSIST NOT AVAILABLE FAULTS

[Oscar01]

Another one, last 22nd driving, and today when starting the car, the bad thing is that the failure does not go away even if I wait a long time to restart.
In my case, in addition to all the faults, the windscreen wipers start on their own, and do not stop, which would be very convenient, if it rained of course.

I have an appointment for this problem at the end of the month in Atlanta, will post after to share the findings and results.

Update. The dealer in Atlanta diagnosed the problem as the steering angle sensor needing to be recalibrated. Drove from the dealer home to Kentucky with no more issues. Problem appears to be solved.

The dealer has replaced the control unit under the steering wheel and everything is perfect.

I have the same problem on my IG. The problem in my point of view is associated with water or wet conditions. First started when I drove the vehicle in a muddy road with lots of water splashing. Now the problem happens when ever I take the vehicle for a car wash.

B1 just turned on today at about 2k miles. Turned off and on still illuminated. Haven’t been back to dealer. Will ad to the list of warranty issues to look at.

I am having the "TSA Not Available" message on a new Grenadier. I have never been off road in the vehicle, so it shouldn't be mud or debris causing the issue. It has happened four or five times driving down the interstate, and it has cleared each time by turning the vehicle off, removing the key and then restarting. I see several posts about people taking theirs to the dealership for repair. Have the dealers been able to correct the issue?

Lots of electrical gremlins seem to be cured by a full battery charge. These vehicles sit for weeks at a time during the ship ride over, at port, car hauler, and at the lot where you bought it.

I picked mine up 1wk after it came in, drove almost 3hours home and when I put it on the charger the next morning, it was at 65%. It took more than a day to reach 97% (2 amp per bank NOCO charger). Something I’ve always done with my vehicles.
