| Description of the problem | I recently had the ecodiesel update installed on our 2014 ecodiesel jeep grand cherokee. The statement from the manufacturer is the driving conditions, fuel mileage, and performance will not be impacted due to the ecm update. These are false statements as the updated has greatly impacted our vehicle! Fuel mileage as decreased greatly, there is a huge lag in the turbo, and the transmission shifts gears all over the place. The update is unsafe! My wife drives this car with our twin 15 month old boys. The lack in response of the turbo makes it unsafe while driving on the freeway. There is no get up and go, it's difficult to merge into traffic, and nearly impossible to pass. There is no responsivness in the throttle to feel like you have control over the car. We loved this car before the madated update (we live in california, we have to get the update to register the car). No we feel like the car is unsafe to drive with our children in it! |
