2015 Cadillac SRX Transmission and drivetrain Problems

“On several occasions over the past 3 months the car would jolt while accelerating in the 20 to 30 MPH range so bad it felt like I was hit from behind. Felt like the transmission got caught between gears. Took the car to the dealer and had to pay over $275 for diagnostics and reprogramming even though car was still under the power train warranty. The dealer did not know if this was the fix. Very disappointed this wasn't covered under the warranty.”

And they were less expensive cars. The car was bought in novi michgan and was taken to virginia. It was driven around washington dc metro area for almost one year. …”

“On Monday, August 5, 2024 when I started the vehicle and began driving to work I noticed upon startup the engine was clearly noticeably louder. It also made a strange bogging downshift type noise when idling. Upon driving, the noise seemed to go in and out but once reaching approximately 40mph the noise got noticeably loud again and the vehicle seemed as though it was having gear shifting issues. I had the transmission fluid flushed and filled costing me $300. …”
