Our middle seat belt has stopped working in the back seat- we have not had it replaced yet. No damage was done on it by us, but will not click into the buckle. Driving on the hi-way engine started making awful noises. We pulled over and had the truck towed to Royal Moore GMC in Hillsboro Oregon as we didn’t want to cause any more harm to the engine. Royal Moore GMC informed us the engine rod bearing failed on [XXX], leading to breaching of the engine block by the rod. This caused us to replace the entire engine at the cost of over 13,000$ and no vehicle for over 3 months. (Along with engine replaced they told us we had to replace the O2 sensor as the light came on after the engine was replaced). We had to take a hardship loan to get the engine replaced, and had the truck back for 1 day before we had a o2 error l light came back on. At this time (May 5th) we are still waiting for our truck back. Royal Moore doesn’t know why the engine light is on- and contacted TAC for GMC. We also contacted GMC multiple times when we were waiting for the engine. They have offered no help to us besides empty promises to call us back later.
