We first noticed the vehicle's lack of power and sudden increase when driving at a stop light/sign. We checked and REPLACED spark plugs, cables, coils, and a new battery. We became highly concerned when the vehicle would accelerate while driving and the RPMs would toggle between 500-1500 RPMS without pressing the gas. We immediately took it to an authorized mechanic, who found excessive noise from the transmission area and found debris/metal. No codes were present when a system performance was done. The vehicle only has 68806 miles on the odometer. The transmission had to be fully replaced, which cost over $7k. The replacement was done. This seems to be a common issue (Transmission replacements) with this vehicle as now we're hearing more about it. PLEASE check this as we could have easily been in an accident from the loss or increase of power without notice and NO WARNING lamp indications. This was a very expensive repair caused by the manufacture and not user error. We paid a lot for this particular vehicle and certainly love it but am concerned about this expensive safety/mechanical issue.

When I was merging on the fwy my car accelerated and I couldn-??t slow it down. I had to get off the fwy and break really hard. Driving on the fwy and not being able to control the speed or breaks could of caused an accident or cost us our lives. I have an appointment with the dealer service center on Sept 20, 2022. A few weeks ago I noticed the car was having trouble sifting gears.
