The company emailed all affected Model X customers, a spokeswoman for Tesla told ABC News today.
The recall involves Model X cars built before March 26. The company is asking those customers to bring in their cars to have them checked. The company said it has not received any reports about this issue and it only discovered a potential problem during additional European seat strength tests prior to selling the Model X outside North America.
"Recently, during an internal seat strength test that was conducted prior to the start of Model X deliveries in Europe, the recliner in a third row Model X seat unexpectedly slipped," the email to customers stated.
"The recliner, which is provided to us by an outside supplier, is the locking hinge that allows the third row seat back to fold forward, and if a recliner were to slip during a crash, the seat back could move forward," Tesla also said in its email. "Similar testing was conducted before the start of deliveries in North America, with 15 confirmation tests having been conducted without a single recliner failure. Despite these prior successful tests and no reports of a third row seat slipping in any customer vehicles, we have decided to conduct a voluntary recall as a precautionary measure and will be replacing all affected third row seat backs."
Tesla told customers that a fix to the issue is "already in place."
"We have worked with our supplier to develop a new recliner design with improved quality that resolved the issue," Tesla told customers. "We are now constructing new third row seat backs to match all affected vehicles. Your service center will contact you to schedule the installation of your replacement seat backs as soon as they are available."
The company estimates all replacements to be completed on a rolling basis over the next five weeks. Until the recall is complete, Tesla said customers can drive their cars, but the company advises that passengers avoid sitting in the third row.
Just weeks ago, Tesla introduced its lower-priced, $35,000 Model 3 car that will be available in late 2017.
