SACRAMENTO, California — Owners of Volkswagen diesel vehicles are still in a holding pattern as the California Air Resources Board rejected the automaker's plan to repair 2.0-liter diesel cars fitted with illegal software that allows them to bypass U.S. pollution regulations.
California regulators said they rejected the proposed recall plan because it "contains gaps and lacks sufficient detail."
They also said the "descriptions of the proposed repairs lack enough information for a technical evaluation" and that "the proposals do not adequately address overall impacts on vehicle performance, emissions and safety."
CARB also issued a new notice that Volkswagen had violated California air quality regulations.
CARB told affected consumers there is nothing they need to do now.
"You will be notified as to the details of a corrective action, buyback or any other remedy," it said.
"Those are being handled through a separate action," CARB said.
The U.S. Environmental Protection Agency issued a statement saying it "agrees with CARB that Volkswagen has not submitted an approvable recall plan to bring the vehicles into compliance and reduce pollution."
It added: "EPA has conveyed this to the company previously."
CARB and the EPA are working closely on a recall plan for the affected cars. But California regulations have different processes, timelines and requirements from the federal government.
A recall is still expected to be part of the potential resolution to VW's diesel-emissions scandal.
Regulators are still working with VW to determine if the vehicles can be repaired and reprogrammed to meet emissions standards while ensuring that vehicle performance is not affected.
Volkswagen Group of America acknowledged the CARB announcement, saying it "addresses the initial recall plans Volkswagen submitted to CARB in December."
"Since then, Volkswagen has had constructive discussions with CARB, including last week when we discussed a framework to remediate the TDI emissions issue," it said. "This week, we have been working with Kenneth Feinberg to develop a swift, fair and independent program, which will provide a comprehensive remedy for our customers.
"We are committed to working cooperatively with CARB and other regulators, and we plan to continue our discussions tomorrow when we meet with the EPA."
The 2.0-liter diesel vehicles affected by CARB's new ruling include:
2009-'14 Volkswagen Jetta SportWagen
2010-13 and 2015 Audi A3
2013-'15 Volkswagen Beetle
2013-'15 Volkswagen Beetle Convertible
2010-'15 Volkswagen Golf
2009-'15 Volkswagen Jetta
2012-'15 Volkswagen Passat
2015 Volkswagen Golf SportWagen
Edmunds says: There is no immediate solution in sight for frustrated owners of these 2.0-liter VW diesel vehicles.
