The engine has been reported as failed. It is available for inspection. The safety of the persons in the vehicle and on the road around us were at risk, specifically with the loss of acceleration and power while driving in traffic and merging. Vehicle became unsafe for use for our family to use so we towed it to be evaluated at odometer reading of 97,181. What happened: Vehicle suddenly started making knocking noise. While driving the vehicle a sudden loss of acceleration and inability to accelerate. Engine started to shut off when it had been in park and then placed into gear. Towed vehicle to be assessed by a mechanic. When assessed at a mechanic, the problem was confirmed and it was also noted that oil had been consumed and noted to be loosing oil internally and has burn on dipstick. No oil spots noted in area where car had been parked or leaking oil on engine. Mechanic assessed that there was engine failure and the engine would need to be replaced. Mechanic also ran diagnostic testing and noted to only have active codes for the tire pressure monitor system of C1212 VSS. Diagnostic health report noted to have no issues. Readiness monitors completed with no issues. Diagnostic health report available. Transported vehicle to dealership, where it was inspected and engine issue was confirmed as well as identical health diagnostic report. It was reported that this model was not part of the recall and warranty extension because it is a V6 engine and not a 4 cylinder so manufacturer would not be replacing engine. Due to being the second owners of this vehicle, we do not meet criteria to utilize the 100k mile warranty. All of this has occurred with out an engine warning light turning on the dash or service code being found when computer was interrogated.
