Service Engine Light On Problems of Buick Regal

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.

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.

I was driving down the highway, 78 mph in rush hour and my engine died/no power, no brakes, no steering. Heavy traffic, no control. I made it to shoulder, very difficult to ease the vehicle over. No warning lights. Engine just died. No control. Once the car stopped after rolling at a high speed, I tried to start my engine. Engine started,and able to proceed. Next day, similar incident happened I was turning a corner. The same thing happened, I was going a lower speed. I had less control after the engine died, no warning lights etc. Very difficult to maneuver. I turned the key and it started. I took it to the dealer. They said needed oil change, and 3 quarts low on oil. And I was 1000 miles over . They were sending me home with oil change, I pleaded to look into further as I was in fear of my life driving. The service sheet indicated the car had multiple cam actuator system failure codes. The service manager said low on oil, and was safe,he went to get the car. The car stalled on him . . . No power, no alarms,no service engine soon lights, etc. Eventually, I convinced them to give me a vehicle to drive after initial denial. 1 week later, they have found nothing wrong. Said exhaust cam shaft actuator was broken. They replaced the timing chains, the actuators, and selenoids. Still no explanation why my car died driving down the road at 78mph they said sometimes it takes 3 failures or key cycles before an alarm will be set. Not sure if they truly found the problem so they have asked to drive my car for several days to see if the default continues to show up. I am very concerned that an engine should stop while traveling at high speeds 3 times before an alarm system or warning would ever be given to the driver that there may be a problem. I am still very concerned and am not sure if I should be driving this vehicle or not for fear of my life.

The check/service engine light comes on. After a few days it goes away. I have had the codes read and the issue cannot be determined. Sometimes the acceleration from stop does not respond timely. It makes it difficult when merging on freeways. I was almost involved in a car accident when the first incident occurred due to slow response of acceleration. Maf has been clean. The a new maf was installed. Nothing has changed. Also I am not sure if this is related but I cannot run my air conditioner until the car has been running for a few miles. If I do the compressor will make an awful noise. An odor has started to come from the vents when the air is not running.

Tl- the contact owns a 2011 Buick Regal. The contact stated while traveling at any speed the service engine light had illuminated intermittently more than once. The vehicle was taken to an authorized dealer who did not diagnose nor repair the vehicle. The code was cleared on the instrument panel by the authorized dealer and the failure recurred. The contact had continued to see the service engine light illuminate and the vehicle was taken to an authorized dealer who diagnosed that the crank shaft sensor needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The approximate failure mileage was 40,000. Dyd crank shaft sensor.

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.
