Hi! I have 2 Acura MDX Hybrid customers in my garage. (Same as mine).
They have two problems.
1. Problem with water pump equipment (pump is working on the table).
2. There is no DTC error in iHDS and the PowerSystem flashes on the clocks and the rear engines do not work.

Do you have any ideas? Does anyone have a Service Manual?

It is very unusual to have issues with the 17-20 MDX Sport Hybrid and 14-20 RLX Sport Hybrid. Just not enough data point for 100% unique powertrain, not a lot of sport hybrids sold, or very few sport hybrid owner's participant on this forum to have a good knowledge base compared to the 14-20 3.5L MDX. I would also post in the RLX forum since the Sport Hybrid powertrain is probably 80%-90% the same for both vehicles. I would also give more info on the MDXs like year, mileage, and any accidents to help other owners to anticipant future problems.
