1023 diesel set my 2011 Power stroke. Went in for one problem and found a few more. Worked with me to do what need to be done. Great work and Joe was always there step by step keeping me in the loop. Thanks again, my truck has never run better.

This question is very difficult to answer. Today we face many challenges when it comes to identifying the root cause of a customer’s concern. Vehicles are more complex than they have ever been, requiring access to many special tools, software, and training to service, and there are many variables involved, so no two concerns are ever quite the same. Here at 1023 we have obtained access to dealership-level diagnostic software for Ford, Ram/Dodge and Chevy/GM, as well as factory-trained and certified technicians, to help us overcome these challenges. Once the root cause is identified, we then face challenges when it comes to obtaining quality parts; these days parts availability is a major concern. At 1023 we have partnered with some of the largest OEM wholesalers to provide the highest quality replacement parts at fair prices, giving the customer confidence that the repairs were made with quality parts we can stand behind. Because of these challenges, we are not able to provide a completion date at the time of scheduling an appointment. What we can do is make a commitment to all of our customers that we will do everything we can to ensure that the repair is done swiftly without sacrificing quality.
We do not perform repairs with parts that the customer provides. We are not able to provide support, warranty or ensure the quality of repairs with parts that we have not purchased through our industry partners. When we have an issue with a part that we purchase through our industry partners, we receive support in the form of technical information, and in the event of a parts failure we are reimbursed for the time we spend replacing the failed part under warranty. We cannot provide this to customers who supply their own parts, so we are unable to perform these repairs.
At 1023 we have a very specific repair process that we follow for all repairs to ensure that the vehicle is repaired correctly the first time. This holds us accountable for the results. If we deviate from this repair process, we no longer have control of the results and cannot guarantee our customer that our service has met their expectations.
We are unable to provide an accurate estimated cost for repairing your vehicle without first getting the vehicle into our shop and starting our repair process. There are many factors involved in determining the root cause of your concern, as well as determining the proper repair plan to suit your needs. Because of this, any estimated cost we give before performing our testing and inspections would be inaccurate.
We always prefer to use OEM parts whenever possible, and whenever it is determined to be the best option for the customer. That being said, there are times we will recommend an aftermarket replacement part or an aftermarket upgrade. An example of this would be the fuel supply system for a 98.5-02 Dodge Ram. The factory fuel supply systems were plagued with issues, and there are better alternatives on the market that make sense for a lot of customers. Ordering those can slow down the repair, so if time is a high concern we might suggest alternatives that can be supplied from our local retailers.
