Does the timing chain really needs to be replaced?
What is your question?
The camshaft solenoid was replaced to fix check engine light with fault code P0024. Check engine light reappeared after a month with same fault code. I was advised that I now need to replace the timing chain, tensioners, and guides. According to the technician, the timing chain may have stretched a bit because of wear and tear. Which is causing the check engine light to reappear.

Depending on mileage and if you hear a rattling noise on cold starts you may not have a timing chain issue. I would recommend logging the cam sensor data to determine if the timing is off. I had a similar situation caused by a intermittent connection at the ECM cause cam codes and limp mode on acceleration. Timing chains are very expensive so I recommend spending time confirming it with proper diagnostics. The trick is finding someone with the knowledge and experience to do it.
