Blind Spot Detection problems of the 2018 Chevrolet Traverse

Hello this particular vehicle often gives us a message stating that side detection is temporarily unavailable and the main issue is the transmission seems to have severe shufdering issues and sometimes gives a shift to park message ive read others having this same issue being recalled but my VIN is not listed! the car is available upon request for any inspections necessary.

My 2018 Chevrolet Traverse, has unresolved safety defects that endanger occupants and other road users. These include transmission failure with loss of acceleration, “shift?to?park” malfunctions preventing engine shut?off, inoperative blind?spot/cross?traffic sensors, faulty tire pressure monitoring, and an active oil leak from the timing gasket cover. These issues occur unpredictably during normal driving and parking, creating an immediate risk of collision, roll?away, or engine fire. All of these issued happened within a very short time frame. June 2025 and I took my car into crews chevy, they want over $15,000 to repair. All of these items I have mentioned have numerous class action lawsuits (that they have won) for the year of my vehicle. I have spoken with gm (and have a case number) however, they are unwilling to repair, at no cost to me. I have an [xxx] daughter and work 7 days a week. I have been with out a car since [xxx] due to these issues. I do have the estimate for the repairs if needed. I do not have an actual repair invoice, as I wasn't able to afford the over $15,000 repairs. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

When driving my vehicle with the air condition on after about 25 minutes, the audio system completely goes out. No sound from the stereo, the backup camera alert, the blind spot alert, the "clicking" sound from the blinkers, all chimes, everything. The mechanic looked at the car and stated that this is a result of the condensation from the hvac system entering the active noise cancellation (anc) module through the module vents. He stated this should have been a recall as it is an extreme safety hazard as it prevents any audio alerts of the blind spot or backup camera warning systems. He states the anc module should be replaced and a secondary shield should be installed to prevent this in the future. The sound eventually comes back once the condensation dries up but once the air condition comes back on again shortly all the sounds go out again.

Side detection unavailable alert keeps coming and off on, when car is started. The alert comes and goes.
