I have a 1998 Buick Regal GS with approximately 85 000 miles on the odometer. As of the last 10 000 miles or so, when the turn signal is used, the lights come on the dash, the engine begins to shut down and I am sure it would stall if I didn't put the turn signal stalk in the neutral position. I have not been helped by the a Buick dealer who said he researched the problem and said he had no knowledge of such a situation. I went on line to the NHTSA site and found no fewer than 8 complaints lodged that were reporting exactly what I am experiencing. At the same NHTSA site, there are numerous complaints about engines cutting out WHILE IN MOTION. I asked (4/17/08) NHTSA what it would take to nudge GM to voluntarily recall this model. What I suspect is that the same problem exists with a ton of GM vehicles. In the near future, I will be visiting the NHTSA complaint site to see if the Regal of other model year has experienced the very same problem. I guess it takes a number of deaths of important people for NHTSA or anyone else to push GM into doing what's morally. And people wonder why the Japanese are taking the lead in automobile satisfaction. Does anyone out there know what the solution is to my vehicle's problem? Please and thanks. Wojo
