| Description of the problem | Vsc engages at highway speeds: vehicle alarm sounds, brakes deploy abruptly and unexpectedly, steering pulls, accelerator goes dead (pulse races, adrenaline courses). First complained to dealer after four incidents in first 20k miles: had online testimonials of yaw sensor, steering angle sensor and ecm replacements as possible remedies; dealer rebuffed my complaints, denying service to sensors, and suggested my tires had 'gone square'. I have lived with the condition for a total of seven years. The car now 'goes off' maybe three times per every 20 miles driven, unpredictably and always shockingly. My family refuses to ride in the car. I cannot sell it in good conscience, as the defects cannot be confirmed by the dealer (and apparently therefore do not exist), so there is no way for it to be 'made safe' for a succeeding owner. Its remaining $10k+ equity has been nullified by this defect. |
