My Nissan Altima Hybrid needs a new PCM/ECU. With a replacement, should everything be alright going forward or is this a warning sign of future engine problems?

Hi there, ECU can fail with out any reason, but they can also be affected by other problems with in the engine management system, depending on the fault that you are in counting, a system scan may show up any other potential problem as well, with out a full system diagonios one can never be sure,
