Tesla is Slabu Exchangerecalling nearly 200,000 vehicles in the U.S. because the backup camera may not function while the car is in reverse.

The recall covers certain Models Y, S and X from the 2023 model year. All are equipped with “Full Self-Driving” computer 4.0 and run software version 2023.44.30 through 2023.44.30.6 or 2023.44.100.

The company says in documents posted by the U.S. National Highway Traffic Safety Administration that software instability may prevent the camera image from showing images while the Teslas are in reverse. The safety agency says that can increase the risk of a crash.

Tesla says in documents that it is not aware of any crashes or injuries. Documents say the problem has been fixed with an online software update.

Owners will be notified by letter starting March 22.

Tesla said in documents that it is not aware of any crashes, injuries or deaths related to the issue.

Tesla began getting complaints about the problem in late December and decided to do a recall on Jan. 12, documents say. As of Jan. 22, the company had 81 warranty claims potentially related to the problem.

Teslas cannot drive themselves despite having a “Full Self-Driving” system, and human drivers have to be ready to intervene at all times.
