Can anything be done to fix liposuction tunnel scars?

You need to give it more time...at least 6 months.  Liposuction wrinkling and tunneling gets better with massage of the neck.  The mandibular nerve gets a lot better within 3-4 months.

You may be surprised to see significant improvement in the appearance and symptoms.  Six months of recovery to eighteen months is needed for the body to improve itself and mature the healing process.  Secondary procedures can be done, but you will need to see a plastic surgeon in consultation, in person, to get the best evaluation and treatment plan.

I would wait 6 months before considering any additional surgery.  It is not uncommon to have some irregularties under the chin and neck following liposuction.  A program of gentle massage of the area will help to improve the hard lumpiness in these areas.   Hopefully the nerve function will return with time.

The answers at this point in time is easy. More time. Things will generally get better over time. And over-treatment is a common misstep when faced with a complication. The mandibular nerve weakness should improve over time.

In addition to waiting, gentle massage of the irregular areas may help. Do not jump into more revisions too soon.Good luck.
