TSA Not Available

[TexasCrane]

Driving back from Big Bend to Austin today, I had a warning light and message, "TSA Not Available". Didn't seem to affect anything and I wasn't towing a trailer, so not sure what was going on. It appears to have reset itself after getting home and shutting the vehicle down. I can see some references to this in combination with other ESC-related warning lights, but I didn't get any of those. Has anybody else experienced this? It came on after about 6 hours of driving, so I'm not sure if that played a role. The most annoying part was that unlike the tire pressure warning, I couldn't dismiss it and get it to stop popping up every 30 seconds on the info screen.

I have had the same TSA UNAVAILABLE error pop up a dozen or so times as well. I’ve never towed a trailer with it. Sometimes it will turn off after a few minutes of driving but if it doesn’t, it always clears after a restart.

It is slightly annoying that you can’t permanent clear it when it pops up. Hoping there will be a fix for this and several other little niggles via software update soon. I am nearing my 12k mile service and hope to have this addressed when it’s at the dealer.

I have also had this error pop up randomly. Probably a dozen or so times in the 2500 miles I have driven the Grenadier.

Shutting down and restarting has always seemed to clear it out.

Shutting down and restarting has always seemed to clear it out.

The cure for many ills.

Same warning light for me driving back to Williamsburg yesterday. Not sure what it means or if it is an issue.

I get this occasionally for no reason at all. Frankly I wish it would just stay shut off and that the light didn't work.

Yep, same issues happened to me, on numerous road trips, the trend I have documented with the dealer and in my notes are, it's usually longer highway speed trips (>100 miles in length or 2 hours) and is seems to be triggered by any sudden movements of the wheels, when you are changing lanes, trying to avoid something like debris in the road, etc. Dealer went in the system and checked there are no permanent or temporary codes on it so it seems to be another gremlin. The annoying part is if you hit the TSA button it doesn't reset. As mentioned above and like many issues with the electronics you need to turn car off and on to get everything reset.

I'm more concerned that it's a safety issue that if you need the TSA will it actually work? Cause if it's being triggered/disrupted that easily, what will happen if the car actually starts a skid or slide?

Just had my 12k service at 8k and had them address a bunch of items, this being one and they said there was no update for this but they logged it with INEOS and suggested I do it as well. Therefore, all of us experiencing these issues need to formally file them with ineos to make sure it's added to their backlog of things to address.

I’ve seen this too. Seems to be on sections of roads where multiple lines have been painted and it’s not clear what the lane is. I get the Take a Break message a few times, then the TSA Unavailable pops up. I’ve also seen it when quick swerving to avoid something too. My guess is that it’s intentionally turning itself off because it thinks it’s unreliable.

I have my 12k service coming up in a couple weeks so I’ll be sure to note it with the dealer. Thanks!

Living the Grenadier life means embracing the quirks like when you keep your tires inflated to 36 PSI its a dance between “over-inflated” and “under-inflated,” depending on weather (and by “cold,” I mean 50°F / 10°C) and driving distance (over-inflated warnings).

Today, I got the “TSA Not Available” warning light. I must officially be a Grenadier owner now, because it didn’t even phase me. Prior to the TSA warning, I did see a low tire pressure alert. Interestingly, several others who’ve posted about the TSA warning also had the low tire icon showing in their screenshots. So maybe the system is doing what it’s supposed to? ...and it’s the tire pressure monitoring system that’s just a bit too sensitive?

Here’s how I understand it:

Trailer Stability Assist (TSA) relies on vehicle dynamics sensors like wheel speed sensors, yaw rate, and steering input to detect and correct trailer sway. If tire pressure is significantly low, it can:

• Impact towing stability
• Skew sensor readings in the vehicle’s dynamic control systems
• Temporarily disable TSA to avoid acting on inaccurate data???

Seems like the TSA system might be working as designed just a little over-cautious when tire pressure fluctuates?

Did you have a trailer connected when it went off? I have never towed with mine and get the warning all the time. Seems like the warning light shouldn’t illuminate if there is no trailer connected…

No, never have hooked a trailer up.

Agree, there should be some logic so that warning only comes on if you have a trailer attached. Or should have been a switch you turn on if you want TSA when towing a trailer.
