Toyota — Fault not sorting out

Address:

New Delhi, Delhi, 110062

Sir,
As in running condition, in screen logo found yellow light with check engine system fault that stops car movement which restarts after 10 mins. This process continued.
On taking this to service provider at galaxy toyata, b-243, okhala industrial area, phase -1, new delhi-110020, on 12/07/2016 with customer id no.:[protected], (Car registration no:- dl1cj8049, make 2010, corolla altis d 4d model, diesel) they not able to trace out the problem and returned with excuse. Again with the same problem, taking my car to galaxy on 18/07/2016, they took 3 days, but not able to sort out with 50 kms test drive.
This problem continuing till date and the service provider not able to sort out this problem (The yellow warning light come in intermittent which stops my car in running condition which retarts after giving 10-15 mins cooling time).
Kindly sort out this problem and proper guide at your end as early as possible.

Thanking you
