Engine knocking. Connecting rod bearing and main bearing failure resulting in required engine replacement. Engine not able to be rebuilt due to cracked main bearing saddles.
I was driving casually when the motor suddenly shut off. No noise indicating engine failure ever happened. I coasted off the road and tried to restart. Nothing but a click. Eventually tried replacing starter motor but that didn't work. No engine lights or codes ever popped up. Turns out engine seized due to failed rod bearings.
I was driving my vehicle under normal conditions traveling around 45mph. As I switched gears from 2nd to 3rd I noticed an immediate loss of power. My vehicle automatically shut off. I pulled over to the side of the road and was not able to restart my car. After the dealership checked the car they said there was an engine failure most likely due to rod bearing failure.

At what mileage does the engine typically fail?

A quarter of owners report trouble before 40,600; a quarter make it past 60,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $3,100 for engine repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to engine?
No active recalls currently cover engine issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
