At-fault driver's insurance cut off my rental after 5 days — am I just stuck?

So I got rear-ended pretty hard at a red light about two weeks ago. The other driver's insurance accepted liability pretty quickly, which felt like a win at the time. They set me up with a rental right away and I thought things were going smoothly.

Then out of nowhere they told me my rental coverage was done after 5 days. My car is totaled and I'm still nowhere near finalizing a replacement. Buying a car takes time — I've been dealing with a tight inventory at dealerships, financing stuff, all of it. Five days wasn't even close to enough.

I went back to the at-fault insurer and they basically said "we covered a reasonable amount of time" and that's that. Super dismissive.

Here's where I'm confused: I actually have rental reimbursement on my own policy. I never opened a claim with my own insurance because the other side accepted fault and I figured I didn't need to. Now I'm wondering if I can open one now, mid-situation, and use my own rental coverage to bridge the gap.

I called my insurance and the rep I spoke to was kind of vague about it — something like "well you're already going through the other carrier" and didn't really explain if I could layer both or switch.

Has anyone dealt with this? Like can you run a claim through your own insurance even after you've already been working with the at-fault driver's insurer? I don't want to do something that messes up any future claim but I'm also paying out of pocket for a rental right now and that adds up fast.

Any experience with this would really help. Thanks in advance.

Yes, you can absolutely open a claim with your own insurance even if the other side accepted fault. I did exactly this. The at-fault carrier was dragging their feet on my rental and I just called my own insurer and said 'I need to use my rental coverage.' They handled it and then went after the other company for reimbursement — that process is called subrogation. You shouldn't lose anything by doing it.

  Ugh this is so stressful, I'm sorry you're dealing with this on top of everything else. Buying a car is already a whole ordeal without a deadline hanging over you. Hope you get it sorted fast — sounds like you have more options than that rep made it seem.

That '5 days is reasonable' line is a classic adjuster move. They're counting on you not knowing your rights or just giving up. The at-fault carrier is supposed to cover your rental until you have a reasonable amount of time to replace your vehicle — not until they decide they're done paying. Push back and document everything in writing, not just phone calls.

Former adjuster here. The at-fault carrier is supposed to cover your rental for the time it reasonably takes to replace a totaled vehicle. Five days is almost never enough for a total loss situation. They know this. What they're also banking on is that you won't escalate.

Your own insurer can step in and cover the rental gap, then subrogate against the at-fault carrier to recover their costs. When you call your insurance back, ask specifically about opening a first-party claim for rental reimbursement and mention subrogation. That word tends to get reps to actually engage.

Opening a claim with your own insurer doesn't mess up anything, especially for rental reimbursement. These are separate coverages. Just make sure you're keeping receipts for every single day you've paid out of pocket — that's potentially recoverable as part of your overall damages, not just through your policy.

Stop waiting. Call your insurer today, open the claim, use your rental coverage. Worry about who pays who later — that's between the two insurance companies, not your problem to sort out right now. You're burning money every day you sit on this.

Also — are you doing okay physically? A hard rear-end hit can cause symptoms that don't fully show up for days or even a week or two. Just making sure you're not so focused on the car stuff that you're ignoring how your body feels. Whiplash especially can sneak up on you.

Did you get anything in writing from the at-fault carrier about the 5-day limit? Or was it just verbal? Because if it was verbal it might be harder to dispute, but if they sent you something in writing that could actually work in your favor when pushing back.
