1) When the car gets to a RED traffic light (or a STOP sign), it should slow down and stop.
TACC doesnt include that as a feature. Thats a FSD feature.
2) When the car approaches a GREEN traffic light with no car in front, I used to get a beep warning and the car slows down a bit allowing me to check crossing traffic, if clear, I slightly press the accelerator pedal and release, this tells the car to move at set cruising speed. Well this feature also DISAPPEARs !!!
This is also a FSD feature.
Did you by any chance have a full self driving trial period that just expired? The normal TACC does not stop at red lights or stop signs and I don't believe it ever did. It just slows when there's an obstacle in front.
Either the OP had a FSD preview that expired, or a subscription that expired, or somehow otherwise had FSD by mistake on their vehicle. Those are the only options since neither feature they are asking about is a part of FSD.
OP, here are the features of each package as stated by tesla itself. You will see that TACC (traffic aware cruise control) includes neither of those features, and in fact only includes traffic aware cruise control and autosteer.
Also, OP, it appears that you were aware that your car came with an FSD subscription as you previously posted:
Lucky , I do not need FSD which is still buggy. I can try for 3 months but I don't even bother with it.
Perhaps you forgot your car had a FSD subscription that expired?

Autopilot
Autopilot includes the following functionality and features:
- Traffic-Aware Cruise Control: Matches the speed of your vehicle to that of the surrounding traffic
- Autosteer: Assists in steering within a clearly marked lane, and uses traffic-aware cruise control
Enhanced Autopilot
In addition to the functionality and features of Autopilot, Enhanced Autopilot also includes:
- Navigate on Autopilot: Actively guides your vehicle from a highway’s on-ramp to off-ramp, including suggesting lane changes, navigating interchanges, automatically engaging the turn signal and taking the correct exit.
- Auto Lane Change: Assists in moving to an adjacent lane on the highway when Autosteer is engaged.
- Autopark: Helps automatically parallel or perpendicular park your vehicle, with a single touch.
- Summon: Moves your vehicle in and out of a tight space using the mobile app or key.
- Smart Summon: Your vehicle will navigate more complex environments and parking spaces, maneuvering around objects as necessary to come find you in a parking lot.
Full Self-Driving Capability
Your vehicle will be able to drive itself almost anywhere with minimal driver intervention and will continuously improve. In addition to the functionality and features of Autopilot and Enhanced Autopilot, Full Self-Driving Capability also includes:
- Autosteer on City Streets
- Traffic and Stop Sign Control: Identifies stop signs and traffic lights and automatically slows your vehicle to a stop on approach, with your active supervision
The currently enabled Autopilot, Enhanced Autopilot and Full Self-Driving features require active driver supervision and do not make the vehicle autonomous. Full autonomy will be dependent on achieving reliability far in excess of human drivers as demonstrated by billions of miles of experience, as well as regulatory approval, which may take longer in some jurisdictions. As Tesla’s Autopilot, Enhanced Autopilot and Full Self-Driving capabilities evolve, your vehicle will be continuously upgraded through over-the-air software updates.
