Broken timing belt 2006 3.5L Santa Fe, now what?
My 2006 3.5L Santa Fe was involved in a low speed collision with damage to the rear driver side door and bent a support structure that had to be cut off and a new one welded on. Picked up the car and while driving home it quit running.
Engine wouldn't crank, towed back to body shop. They said the timing belt is broken and even the metal gear is shattered and lying in the compartment.
Vehicle has 103,000 miles and I never replaced the timing belt (yes I'm an idiot). The shop is assuming that a new engine will be needed.
So my questions are how often does a metal timing gear break due to the timing belt breaking? and how likely could it be that a low miles per hour side impact (car was being driven, not parked, if that matters) could have caused a problem with the timing belt?
Is it just bad luck that it crapped out while driving it home from the body shop? I did drive it there with no problems so I'm assuming they're not related but I'm no expert. My daughter was driving so I have no idea if there were warning signals prior to it going.
From reading other posts I'm pretty sure this is not a free floating engine so there is likely significant engine damage. Is there a typical failure mode assuming about 40 miles an hour at time it broke? Bent valves certainly, but would it need heads, pistons, rings, whatever? Trying to get a handle on what all might be involved and whether an experienced mechanic could overhaul it for a reasonable price or does a new engine sound more likely?
Just spent $500 on paying a deductible for a car that now has a blown engine. Wonderful.
Thanks in advance for any replies.
