2017 NSX Hybrid System Warning Light - Loss of Power

Vehicle: 2017 Acura NSX

Hey everyone, I'm experiencing some concerning issues with my 2017 Acura NSX. Recently, a 'Hybrid System Malfunction' warning light popped up on my dash, and I've noticed a significant loss of power, especially during acceleration.

The car feels sluggish, and sometimes it struggles to start. I'm worried about driving it like this. Has anyone else with a 2016-2026 NSX encountered this problem? What could be causing this, and what steps should I take?

I haven't had any recent work done on the car, and it's otherwise been running perfectly. Any advice would be greatly appreciated!

ClearTheCode admin answer:

Experiencing a 'Hybrid System Malfunction' warning and loss of power in your 2017 Acura NSX is a serious concern that requires immediate attention. This typically indicates an issue within the complex hybrid powertrain.

Here's what you should consider:

  1. Check the 12V Battery: While it's a hybrid system warning, a weak 12V auxiliary battery can sometimes trigger various seemingly unrelated warnings. Ensure your 12V battery is in good health and fully charged.
  2. OBD-II Scan: A professional diagnostic scan is crucial. Common OBD-II codes associated with hybrid system issues include:
    • P0A80: Replace Hybrid Battery Pack (often indicates degradation or failure of the high-voltage battery modules).
    • P0AFA: Hybrid Battery System Voltage (could point to issues with the battery management system or individual cell imbalances).
    • Other codes related to the motor-generators or power control unit.
  3. Causes: Potential causes range from a failing high-voltage battery pack, issues with the power control unit (PCU) that manages power flow, problems with the motor-generators, or even wiring/sensor malfunctions within the hybrid system.
  4. When to See a Shop: Given the nature of a hybrid system malfunction and the performance impact, it is highly recommended to have your 2017 Acura NSX inspected by an authorized Acura dealership or a specialized hybrid vehicle repair shop as soon as possible. Do not ignore these warnings, as continued driving could potentially worsen the issue or leave you stranded. They have the specialized tools and training to safely diagnose and repair high-voltage systems.
