Was waiting on dealership to catch up to bring in for a transmission problem. I know it is transmission related due to not wanting to shift properly and the fact my friend has same make and model only about 100000 more miles than mine does was doing same symptoms and she took to 3 or 4 mechanics and all said nothing wrong..no codes show up...needless to say after about 2 months it stalled out on her on interstate with speed limit 75 and she barely moving. I myself was at a sharp curve in turn lane waiting on traffic and when I braked to stop it made horrible sound and felt like brake was pushed through floorboard. When I was clear to go i push accelerator down to the floor and am barely inching along and am now stuck in the road in a 90 curve where its hard to see traffic coming. This was very scary and traumatic having this happen. I'm just glad it was only myself and the other drivers were being observant and paying attention to the road. This has happened a lot compared to research on blogs car complaints websites. The common problem is it doesn't give a code when diagnostic checked. 99% of cases show they best guess or find something else wrong and you pay 3 or 4 charges until you finally convince them its the transmission and then you're out 5000. Not counting the average 4500 you've already pd due to not listening to the driver of their vehicle and causing unnecessary charges and leaving you without a vehicle too long that isn't necessary.

Driving at 55mph, suddenly the Traction Control blinks on & off, the vehicle starts skipping. Next, Service Stabilitrack System appears and I almost come to a complete stop, Engine Running at Reduced Power appears. I barely made it to the side of the road, traffic was heavy at the time. This is apparently a common issue with other Owners and could be a number of different sensors, parts malfunctioning.

I bought my car at the end of April. June 27. 2019 was the first time that I had the stabilitrak issue. At 102206 miles, took it to the dealership and was told it was the rr and rf speed sensors and right front and right rear passenger wheel bearings. Today September 9, 2019 and at 103003 miles it happened again. I was driving both times, and both times the brakes grind and I could feel looseness in the gas petal and it squeaks like an old spring bed. I am a disabled veteran and I only use the car to get to va appts, grocery store and general errands. I can't afford to spend another $1,200 to get this fixed. I have read online many of the same complaints. There seems to be an issue with this stabilitrak system and no one seems to know what to do to fix it. Please let me know what steps will be taken to fix this issue before I contact a lemon law lawyer.
