My needle hits / bottoms out on the bobbin holder and hook assembly. Do do I need to fix timing

Can be several causes. In typical probable order for rotary hook machines;
1.Top thread tension is too high (lower tension)
2.Top thread snagging at spool or elsewhere (for hoizontal spool use larger spool cap and/or machine not threaded per specific instructions)
3.Bent needle or barbed needle point (replace needle)
4.Needle not properly inserted into holder (see specific machine instructions)
5.Debris in shuttle hook/race (clean bobbin, hook, race)
6.Wrong bobbin (replace with proper machine bobbin)
7.Bobbin thread tension too high (reduce bobbin spring pressure, likewise top thread tension)
8.Poor quality or extremely light thread (if using cotton only thread, test sew with a polyester blend and see if problem goes away)
9.Bobbin case (replace bobbin case)
10.Machine timing. (check/adjust timing)
11.Burr in hook race, this can happen if a broken needle point jams in the race (remove burr or replace race)
12.Machine timing. (adjust timing)
13.Hook is worn or damaged (typically not a worn hook unless a few hundred hours of use, look for a barbed or bent hook point) Watch following Singer video... see testing top thread tension.

There are several things that can cause this, but essentially the hook is not catching the tread loop when the needle goes down. Sometimes the machine has gotten out-of-time, most frequently it's from lint buildup in the bobbin carrier assembly or a bent needle. Try a new needle first and make sure you have it inserted properly in the machine with the eye facing the bobbin. Most consumer machine needles have a flat that only goes in the needle holder one way, but some universal and specialty needles don't have that flat. If the needle isn't the culprit, have it cleaned professionally. Most machine ailments are resolved by a proper cleaning.

breaking needles from hitting can be from several problems
1-- needle /hook timing is out
2--needle thread tension is too tight pulling needle side ways
thread caught around bobbin holder is top thread too loose
take it in for a service check as the needle /hook timing is complicated to adjust and the problem could be more complicated than suggested

Try installing a brand new needle. It is easy to bend or damage the needle, which is why it is important to change the needle frequently.

If the new needle continues to hit, then the needle/hook timing is off. Take it for service.

This may be a timing/needle bar height problem. Remove the needle plate and watch the tip of the hook as you turn the handwheel towards you. As the needle rises your hook should pass just above the eye of the needle. At no time should the needle hit the bottom of the hook assembly. This requires some special tools and skills to fix find an expert in your area.

Get a new needle first and try that. If that doesn't work, you're timing is likely fouled up and it needs a quick trip to the shop. (Seriously, that takes about 5 minutes to fix so depending on how busy the shop is you might be less than an minutes.) Also, don't let them recommend a bunch of other services. If you were so inclined and have a screwdriver handy, google "fix sewing machine timing" and you can tinker with it yourself but it's no guarantee.

here's something to check
is the needle inserted all the way in to the needle holder?
needle--flat side goes to the back of the machine
is the needle clamp screw tight or loose?
if the needle is correctly in the needle holder & the needle clamp screw is tight --then the needle bar is out of time & need to be serviced
IF YOU DO HAVE TO TAKE IT TO BE SERVICED AFTER YOU GET IT HOME STOP RIGHT THEN & SEW ON THE MACHINE TO MAKE SURE THEY FIXED THE MACHINE & IT SEWS LIKE IT SUPPOSE TO, I HAD ONE CUSTOMER THAT TOOK THEIR MACHINE TO A SHOP & THEY CLEANED IT AGAIN & DIDN'T FIX IT BUT CHARGED THEM FOR IT & THEY BROUGHT IT TO ME TO FIX & IT HAD TO BE RETIME
did you get a instruction manual for the machine if not check at singer

That isn't the timing. If the hook is hitting the needle the hook is too far left - or close to the needle. It's adjustable by loosening the set screw at the base of the hook and by gently tapping the hook away from the needle. You want the hook to be close enough to the needle to pick up the thread loop that's formed just as the needle bar is rising.

If the needle is hitting the hook under your bobbin case, your machine is out of time. Unfortunately, unless you are familiar with this particular repair, you will need to take it to a qualified repair technician. You can however try a new needle and make sure that it is in properly. If the needle is not bent, then I am afraid you will need to take it in to be repaired.

Remove the bobbin, bobbin case as well as the shuttle hook. There are black pins/holders that hold the shuttle hook. After you remove these 3 components, make sure there are no thread stuck in between the 2 hook pieces as well as the bobbin shaft. Most of them time, there are either fabric or thread stuck. If not, make sure the needle is not hitting the feed dog or the hook.
