Page 4 of 4: complaints 71 to 76 of 76, newest first, as owners wrote them.
Vehicle stalled while stopped at intersection - occurred twice in 2 days. Subsequently vehicle experienced excessive cranking to start - twice. Orange buick serviced the vehicle and repaired a wire harness that had been worn. 2 days later while driving the vehicle at 30 MPH the vehicle lost all power (engine and electrical), I had to turn on the flashers and pull on to the shoulder. Once the vehicle was stopped I put it in park and it restarted. However, the 'traction control off' light was on and after pressing the button it remained on.
Suddenly about 3 months ago the vehicle began to stall in traffic while being driven. The dash board lights all go off, the radio washes out the presets, when the engine is turned off sometimes the radio presets are erased. Many times the auto locks and unlocks when sitting in the lot. The dealer has worked on it at least five times, two engine control modules, a new wiring harness, the auto has had its radio "recalibrated" this thing is dangerous because it keeps shutting off while driving. Dealer says he has had multiple problems with similar cars, and that they continue to behave irrationally. Obviously an electrical problem, gm denies there is anything wrong, but when it shuts off going 0-60 MPH on the highway there is a problem. Not to mention that when the dash board lights shut off, or the radio starts to act unusual it is very unsafe especially at night. One time the steering wheel radio button were switched, seek was band, and band seek.

After sitting several minutes the vehicle restarted and was immediately returned to the dealer. The vehicle again stalled upon arriving at the dealer . Dealer currently has the vehicle . The vehicle must be repaired to prevent further stalling since driver and any passengers are in danger along with any other vehicles in close proximity. The dealer and buick have been made aware that the stalling creates a hazardous condition for the driver and the public. Due to the repetition of such stalling that has occurred any future hazards created by this malfunction are foreseeable by the dealer and buick. As such, we can only accept the vehicle back upon the dealer's and buick's assurance that it safe to drive at the posted speed limits on the public highways. If such assurance is not possible , then as a matter of public policy the vehicle should be replaced or our money refunded.
While pressing down on the horn, it failed. The dealer had inspected the vehicle several times and could not duplicate the problem.
Instrument panel reading of the numbers is not clear for consumer to see, especially when he puts his glasses on. Driver took vehicle to the dealer, and the mechanic did not have an answer at this time. *ak the problem is that the gray on gray panel was in a six inch recess dash which shades pencil thin numbers and slashes between numbers e.g., 55/60. The most serious problem was the clarity of the speedometer readings going north, south, east, or west. (could not be read at a glance)
