Tl- the contact owns a 2001 Buick Regal. The contact stated that there was a progressing odor which may have been associated with the motor or engine that continued to get worse. As the failure continued, the service engine warning light stayed lit for an extended period of time. The vehicle was taken to more than two dealers and they were not able to replicate and diagnose the failure. The contact later received notification of NHTSA campaign number: 15v701000 (engine and engine cooling) and the dealer was unable to determine when the part would become available. The dealer stated the contact would have to wait to receive the second notification letter. The contact was unable to determine when the vehicle would be repaired. The manufacturer was notified of the failure and was unable to determine when the recall repair part would be available to repair the vehicle. The approximate failure mileage was not available. VIN tool confirms parts not available. Dyd.
My 2011 Regal had to have the lower and upper intake gasket replaced as well as the valve cover gaskets. . A week after that the service engine soon light came on and the mechanic said it was the throttle body gasket. I then got it replaced and then a week after that the service engine soon light came on again. It was pulling up a code for a vacuum leak. Wtf! my boyfriend turned the light off and it hasn't come on since, so I don't know if it was a glitch.
