My wife has been driving our 2009 Toyota Matrix and noticed the oil light flicker on and off as well as a “grinding noise” the last couple days, when I got in to drive it sounded horrible and immediately took it to the repair shop we had our last oil change at. After they found oil shavings on the dipstick we are now getting a quote for 5500$ for replacing the engine. Apparently the lack of oil in the vehicle ruined a bearing or so they are guessing. Now I know for a fact it was not leaking oil or burning oil significantly enough to notice (I say goodbye to wife when she leaves and would have noticed either,) so I am left feeling they failed to put enough oil in or any at all. So I know we are at fault for not dealing with a notification light immediately but am wondering if I have any ground to stand on to complain and request they at least help pay for a new engine. This repair shop has replaced my water pump and I have gotten two previous oil changes from them, the last time the vehicle was in for an oil change they recommended spark plug replacement and fuel injector clean up…other than that everything with the car was fine. This replacement cost pretty much totals this vehicle, if I can’t get them to help pay for this, what would be my next best option? The car still runs, but for how long with this kind of issue and at what cost to safety? Cheers to whomever reads this and offers help! Thank you - Daniel.
edit 1 : most recent change was just under 2 months ago, she only drives to work and back for the most part but took it out of town when the event occurred.
edit 2 : general consensus is that I am learning a very expensive mistake and to always check your oil on a regular basis, beginner car stuff that I have let slide on my wife’s vehicle, I really appreciate everyone here for their advice, I will be done responding to replies.
