I’m getting a bunch of warnings all at once:

• Adaptive Cruise Control problem
• Collision Mitigation System problem
• Road Departure Mitigation problem
• VSA / Brake System / Brake Hold problem
• EPS (power steering) problem
• TPMS problem
• Emissions system problem

Scan tool results:

Engine:

• P2187 – Fuel system too lean at idle (permanent + temporary)
• P0299 – Turbo underboost (permanent + temporary)

Other modules:

• U0416-68 – VSA system malfunction / brake actuator
• P2583-76 – Radar misalignment (Integrated Driver Support System)
• U0401-68 – ECM failure (communication related)

Symptoms:

• Car stalled right after starting once and hesitated to restart
• Acceleration feels weaker than normal
• Power steering warning came on
• All driver assist features disabled

Battery tested good. Charging voltage stays above 14V while running.

Radar/ACC errors started first, then the engine codes and everything else followed.

Looking for ideas on likely root cause (vacuum leak? boost leak? sensor? wiring?) and what to check first.



Thanks in advance.

If the battery and alternator are good, then i would think its something with the wiring
