| Description of the problem | New software update was done to car per recall for "reliability". This recall changes the way the car shifts, such as remaining in 3rd gear, rather than downshifting to 1 or 2. A low speeds such as 15 mph when driving up a hill, the car will not down shift and slow down almost to a stop. Depressing accelerator does not lead to any further acceleration until approx 3/4 of the way down. At this time the car downshifts to 1st and accelerates rapidly, even breaking traction. Similarly when cruising at a steady speed such as 20 mph car remains in 3rd gear, causing engine lugging and very slow acceleration, once causing a near accident as the car did not accelerate as quickly as it did before this software update. Jeep dealer says "shifting as intended" and no errors. This behavior was not present before software update and did not change when dealer attempted reflash. |
