General Motors has announced that it will stop funding the development of the Cruise self-driving taxi.
The company says it will now "refocus autonomous driving development on personal vehicles".
GM also pointed to the increasingly competitive robotaxi market as a reason for the move.
In October, Tesla boss Elon Musk unveiled the electric car giant's long-awaited robotaxi, the Cybercab, at the Warner Bros Studios in Burbank, California.
GM attributed the change of strategy to "the considerable time and resources that would be needed to scale the business".
The company did not say how many Cruise employees could be moved over to GM.
GM, which owns about 90% of Cruise, said it has agreements with other shareholders that will raise its ownership to more than 97%.
In December 2023, Cruise said it would cut 900 jobs, about a quarter of its workforce.
The announcement came as safety officials were investigating the firm after reports of injuries to pedestrians.
Cruise had earlier pulled all of its US vehicles from testing after California halted its driverless testing permit.
The Detroit-based manufacturer's chief executive Mary Barra has previously predicted that the Cruise business could generate $50bn (£39bn) in annual revenue by 2030.
Rival motor manufacturing firms have also struggled with projects to build autonomous vehicles.
In 2022, Ford and Volkswagen announced that they would shut down Argo AI, their self-driving car joint venture.
Meanwhile, the emerging robotaxi industry is also attracting major players.
As well as Tesla, competitors to create self-driving cabs include Waymo, a subsidiary of Google's parent company Alphabet - and technology giant Amazon.
Ride-hailing firms Uber and Lyft also have ambitions to use autonomous vehicles.
