Nissan Titan in here getting a new high speed turbo

We actually get quiet a few of these in here for miscellaneous repairs. A lot of places don’t work on these, dealers even turn them away but we have no issues getting into them 🤙🏻

🇺🇸 Just a heads up! 🇺🇸

Yes—we’re OPEN tomorrow, July 3rd!

If you’ve been putting off that weird noise, check engine light, A/C issue, or maintenance… tomorrow’s a great day to get it taken care of before the holiday weekend.

Don’t wait until your truck decides to celebrate the 4th with its own fireworks. 💥😂
