    Had an issue come up on a Sunday stopped in and was told it would be 3-4 days before they could even check my truck out. Giving them 3 stars only. Because the had the part I needed. However whenever the mechanic I called out called and asked about a part we waited almost 45 min to hear back from the dealer with part number, cost and availability.

    One of the best experiences ever with my truck repairs! We came through St. Louis early morning hours on Sunday 5/3/26, the water pump started failing and derated us. Called and spoke with Chris. He said he couldn’t make any promises because they were short staffed with only 2 techs but he could definitely get me checked in and put in line. They did that and more. We were back rolling in less than 7 hrs. This was definitely a Platinum experience! Big Shout out to Chris and Matt our Service advisors/Techs! God Bless you guys! Yall are Amazing! Thank you so much!

    I can’t say enough about the incredible experience I had with TLG Peterbilt Mid-America. After purchasing my truck from TLG Peterbilt in Fort Smith, I was on my way to Columbus, Ohio when I suddenly broke down in Missouri due to a major coolant leak and a transmission fault. It was one of the most stressful moments I’ve faced as a new owner-operator. I reached out to several TLG locations, and Mid-America was the only one that truly stepped up without hesitation. From the very first call, Zack went above and beyond. He was patient, knowledgeable, and genuinely cared about my situation. In a moment where I felt stuck and overwhelmed, he brought reassurance and took immediate action to help me get my truck safely to the dealership. Even A&A Towing mentioned that TLG Peterbilt Mid-America specifically is known for standing behind their customers, and now I see why. When I arrived, Hunter continued that same level of excellence. He was hands-on, supportive, and stayed with me every step of the way, making sure everything was handled properly and efficiently. And I can’t forget Ron, the mechanic, whose work and dedication got me back on the road. This team is truly special. The level of care, urgency, and professionalism they showed me wasn’t just customer service, it felt like family. In an industry where you can easily feel like just another number, TLG Peterbilt Mid-America made it clear that they genuinely care about their customers. I’m beyond grateful for Zack, Hunter, Ron, and the entire team. Because of them, I’m not just a satisfied customer, I’m a lifelong one. If you’re looking for a dealership that stands behind you when it matters most, this is the place. Thank you again, TLG Peterbilt Mid-America. You turned a stressful situation into a blessing.
