Customer Question
2500HD Duramax Diesel truck and...
We paid over $1,000 to replace (3) knock sensors on our 2014 2500HD Duramax Diesel truck and still have the same problem with the Stabilitrak and DEF error messages. We have currently 91 miles left to get the truck to the dealer again and miss another week of work.
JA: Which particular sensor are you asking about? And have any trouble codes been triggered?
Customer: The stabilitrak, DEF and IDK the name of the third one. When we wiggle in the seat the stabilitrak error message appears. Now the DEF error is displayed saying we have 91 miles to get the truck to the dealer
JA: What is the model of your '14 Chevy?
Customer: 2500 HD
JA: Are you fixing your 2500 yourself? What have you tried so far?
Customer: As I said, we took it to the dealer in August 2017 and paid $1,000 to replace (3) sensors and currently have the same problem.
JA: Anything else you want the mechanic to know before I connect you?
Customer: The truck also have a intermittent problem with the power steering when trying to make a turn at low speeds.
