"Blindspot detected limited" - Anyway to fix that?

"Blindspot detected limited" - Anyway to fix that?

Hi all,

We are new Tesla owners. Got our Model3 a few days ago. The second time we took it on the highway, we got the alert "Blindspot detection limited" and autopilot became unavailable. I searched for answers online but found few answers (potential mist on the cameras being the main one). We've rebooted the car, but that didn't work either.

Is this worth a trip to the service center (an hour long drive for us)? Has anyone encountered any real solutions?

Thank you ahead of time!

Temporary problem or sustained? If its dirt or mist, wiping it off will fix it. If it's something else and sustained, take it in for service.

Don't know what you mean by real solutions.

I've had the same issue on occasion on my S. Hasn't been often enough yet to contact service (maybe once every 2-3 weeks). Once it trips, it will not go away on it's own while continuing to drive. Stopping and exiting the car and returning seems to clear it. Not sure how much time is required or if there is a shortcut. Use of sentry mode does not seem to affect it either.

Seems few people have the problem, so I suspect a hardware issue, such as an intermittent camera or cable. I'll likely wait until HW3 is installed to have them look at it. (P.S. your car being so new should have HW3).

When it occurs, activate the voice button and state "Bug Report - Blindspot detected limited". This will capture the log for Tesla service and may help run it down. If you do get it repaired, I hope you'll come back and say what they fixed.

Also in my case, cameras are clean, no mist either - but good suggestions to check.

Cameras dirty or obstructed. if you are sure that's not the case (you have cleaned them correctly and are free of dirt, debris, smudges, then service appointment required.

Happens to me every time I put my car in gear when the car is facing the setting sun.

httran26 | June 18, 2019

After a good night sleep, it will most likely work again. Use one night is good enough. One time it took 3 nights. Nowadays when I get this error it is because the cameras are rebooting. I see it in the TeslaCam

Mine activates every morning when there is dew on the car. It clears up in minutes.

yumei.leventhal | June 19, 2019

Thank you all for your comment! None of the external factors--dew, mist, car facing the sun... -- are in play (guess that's what I meant by "real solutions").

Thank you, @TeslaTap.com, for the bug report tip. I will let you all know what the service people say.

Saw this for the first time in my car yesterday while heading out. Would warn, go off, and warn again and then went off and didn't come back on. I wiped down where the side cameras were just in case. Hasn't happened again since.

CharleyBC | June 19, 2019

I’ve seen this in a very specific starting circumstance, and it’s happened several times. The car is in my driveway, and the garage door is open ahead of it. It’s afternoon, which, given the orientation of our house, puts the sun in front of the car. So the car has an extreme contrast problem. It has the bright light of the sun in its eyes, yet the bulk of its field of view is the black hole of the open, dark garage. It seems to think it’s blind, and gives that warning. If I either move into the garage, or out into the street and try again, it’s all fine. As a photographer, I totally get this—it’s an exposure problem with no solution.

Like any warranty issue with car especially when new, get it to service and document it as though you were going to need to invoke your state's lemon law. Once established as warranty issue, it will become Tesla's responsibility.

And you want it fixed. I have had no problems yet but either everything functions on the car or Tesla fixes it. I sent the letter opting out of "Arbitration" so the state laws apply if the car has issues.

Not having dynamic cruise makes the car non-functional for me.

"Not having dynamic cruise makes the car non-functional for me."

What?

ADinM3 | June 19, 2019

I had the same condition. The SC can see a few more things in the log if you are having issues even if the screen message doesn't always pop up. If nothing else, they know whether it was the left or right repeater camera causing the issue. In my case it had them stumped as they could see the errors on the left repeater but the normal checks (repeater camera operation, signals where they should be, connectors seated properly, etc) appeared ok. They ultimately suspected a left repeater itself and replaced the assembly and have me monitoring. It has been about a month now and no follow up incidents. Fortunately, there really is not many possibilities for failure as there is only a simple camera with a 3-wire (I think) connection running back and plugging into the computer board.

yumei.leventhal | June 24, 2019

Update: Turned out the "coax cable" and the "B-pillar camera" were faulty. We had to wait for 4 hours today before leaving with the car. Now autopilot is working as well. We observed occasional "flashing" of the images of cars passing on either side, but it's nowhere near as bad as before.

A big shout-out to @TeslaTap.com for the tip: Each time I got the error, I used the voice button and said "Bug Report - Blindspot detected limited". The system seems to recognize the expression "Bug Report" and keeps a log of the errors as they occur. The technician could see the logs and said that helped.

The worst part of the whole thing--we hope it is--was waiting that long. We made a reservation online and were only given one choice for service. When we got to the designated Tesla service station, they couldn't find our reservation at first, then told us we were scheduled for mobile service--the reservation page on the phone didn't make that an option and NOBODY contacted us to confirm mobile service. I had left a message at this station (Mt. Kisco, NY), asking them to confirm it, as I couldn't find the reservation on my phone, but nobody returned the call. The reservation did show up on the account page on the computer.

Basically, Tesla still has a lot of kinks on to straighten out on the customer service end. Fortunately, the people working at Mt. Kisco Tesla are all incredibly nice.

ADinM3 | June 24, 2019

@yumei, exact same thing happened to me as well. I show up to my scheduled appointment and they indicated I was set up for a mobile appointment, but no one ever reached out to let me know. Fortunately, in my case they took me right in and gave me a loaner while they investigated. I've been lucky and had nothing but positive experience with Tesla service so far.

Yeah, Tesla needs to fix the kinks on their customer service side.
I wish this forum has a search function. It's awfully hard to find an older post, even one's own.

I have the same issue with the Blind Spot detection reduced. It appears as though my front cameras on the fenders are not working, It was intermittent at one time, and it seemed as though when the car was turned off and on again, the issue resolved itself. Now it stays on all of the time and the rear blind spot detection is non-functional. I am going to go down to the service center and see if I can get an appointment before Aug 06 which is where they are currently scheduling. I'd really like to get this resolved ASAP.

Had this happen to me today on a 3 hour return trip from KY. Bummer all the way back without full AP on the highway. Cleaned all of my cameras and did a soft reboot of the computer but no joy. Will have to start using the "bug report" feature. I'm surprised the Tech can't pull the data logs from the computer as it issues the error/fault messages.

garretn | November 10, 2019

Keep a date and time stamp of every time this happens they might request them when you open an appt with the SC. My SC has asked me for the date and time stamps on several of the error messages I have been dealing with. They even requested date and time stamps on the back up camera coming up with a black screen. I have been taking pictures in case they are needed for some reason.

My model 3 is 2 months old and started getting both the lane departure alert and blind spot alert simultaneously over the past week. Made an appointment with SC but now getting billed $208 to fix the issue. Is this common?

Magic 8 Ball | November 11, 2019

Necro thread but I will play.

@sou They will often request an up front payment (basically assume the problem is yours to pay for) and if the issue is on them they will not charge you.

mickrat | November 12, 2019

I had this issue. I scheduled a service visit. Before I arrived they had already diagnosed the problem as being a bad b pillar camera. When I arrived for the service visit, they worked on the car and came back to tell me it was actually a pinched wire harness. They ordered the correct part and said mobile service would change it. I still had the problem on the way home from that visit, but since then I haven't. Perhaps they unpinched the wire. I haven't heard anything about the mobile visit and it's been about a month

garretn | November 12, 2019

Mobile service overlayed my wiring harness didn't actually replace the harness. The problem still exists so I scheduled an appt with the SC and they moved my appt out in order to get the parts they needed to fix the issue. They still have not responded letting me know what they have ordered so I can only guess maybe a camera.

Like I have mentioned before in this thread if you are not keeping a log of Date and Time of when this happens you should be they will most likely ask you for this information. Like @mickrat said they can diagnosis the issue before you even go to the appt.
