Isuzu Emond Auto

I had very bad experience with Isuzu service department in Emond Auto they kept my vehicle for 3 months in the service department guessing what is the problem after They change differential on the vehicle under the warranty it did not last me three 3,000 kilometers barely one year. first report from the technician confirmed that the differential was faulty and it needs to be replaced and still under warranty second technician technician confirmed that was faulty and when Isuzu said to them the vehicle longer under the warranty the manager of the service department of service drove the vehicle and he said there is no fault on the vehicle I lost the 3 months Insurance on the vehicle while but the problem still on the differential and almost warranty is out I do not the command Isuzu either Emond Auto for any service to be done on the vehicle or purchase an Isuzu
