| Description of the problem | On 04/06/2016, the vehicle's engine began to run rough and hesitated. Lack of acceleration, even at 4000 rpms (top speed 20 mph at 4000 rpms). The vehicle began to stall and required the gas pedal to be pressed due to low rpms at idle. The problem is intermittent, with no warning to the operator, and poses a significant safety risk on roadways with speed limits above 40 mph. No engine warning light came on to warn the operator. After three occurrences of this problem, in less than 24 hours, the vehicle, with only 1,351 miles on the odometer, was taken to dealership for service on 4/7/2015. After replacing, the fuel pump, the vehicle was returned to the owner on 04/10/2015. Less than 2 miles after picking the vehicle up from service, the problem occurred again, on a 50 mph roadway. The operator was very concerned for her safety as other motorists were swerving around the vehicle and honking their horns. Again, no engine warning lights came on to warn the operator. Once again, the vehicle was taken back to the dealership within 20 minutes of initial pick-up, for further repairs. The dealership has had the vehicle ever since, changing multiple parts dealing wit the fuel systems, and has yet to correct the problem to date (04/16/2015). |
