NHTSA Complaint #11597829 — 2016 ACURA MDX

After traveling about on a 4 hour drive, my daughter who was driving the vehicle slowed down to make a turn. That's when she heard a loud clanking noise coming from the engine. She immediately pulled over and turned off the engine/vehicle. I went to meet her, and replicated the same problem when I turned the ignition switch to to on. It sounded as if there was some large piece of metal loose inside the engine -- it did not have consistency and was highly variable with regards to the sound it was making. The "Check Engine" light was on. Fortunately this did not occurr going at high/freeway speeds, yet the safety was compromised when my daughter was fortunate enough to leverage the momentum to get to the side of the road. Additionally, she was not in a spot where there was a shoulder/it was under an overpass, so she had to be careful and turned on her emergency lights. We had the vehicle towed to the nearby Honda Dealer. I am attaching their report and findings. They recommended engine be replaced; which we agreed to have done. Additionally, we continue to have problems due to the mounting and shacking which we believe comes from the installment of the new engine. We are submitting that report as well. At present, my daughter is not driving the vehicle and is relying on rides or borrowing other people's vehicles.
