2019Tahoe

Mine wasn't lifted, but I had a similar problem. 2019 Tahoe Premier with 37k miles. All four corners got stiff like the shocks had been replaced with straight rods. I took it to the dealer. They replaced the left rear shock and charged me a thousand bucks. Fixed the problem though. Rides fine for now. Not sure where to go from here. I've studied delete kits. I'm actually just waiting until more people have trouble with them and I'll watch for ideas of how to move forward.

Is there a way to soften the ride by changing settings? The original problem was fixed. A softer ride would be nice.

Thanks for sharing all that info, Senior Enthusiast. Before taking it to the dealer, I bought a $35 code reader on Amazon (recommended by Scotty Kilmer). It said there were no trouble codes present, but I'm guessing for $35 it wasn't looking deep enough. Definitely makes sense that all four shocks failed because of a malfunction somewhere in the system. I didn't recognize any error messages on the DIC, but the vehicle was brand new to me and I wasn't familiar with the instrumentation. I could have missed it

I bought a 2019 Tahoe with 37,000 miles from a car rental company. During a 1300 trip, the suspension went from just fine to rough as a log truck. Like all four shocks had been replaced with a solid bar. Long story short, I took it to a dealer, which I seldom do. They diagnosed only the left rear shock was bad. They replaced it and all the others started working right. The reason I'm posting this is nothing I found on the internet mentioned this solution for the problem I had. Now if somebody else has this problem, hopefully they will find this post. I was ready to remove all the magnaride shocks and struts, then install an after market kit doing away with it all. For now at least, I'm glad I didn't. If another one goes bad next month, I may feel differently. I wish I knew how the dealer tech diagnosed the one shock bad. The vehicle was stiff on all four corners.
