Failure Date: 05/30/2024

The service stabilitrak and service powersteering will come up. Have had vehicle hooked up to computer multiple times no codes. The vehicle would not drive. The vehicle has started shaking. The engine light comes on. There is 30k miles on the vehicle. I bought this 3 months ago to have a safe vehicle. My spouse and I are disabled and we do not feel secure. I googled and it says probably a computer error from factory. I'd appreciate if I can get my vehicle recalled & fixed. Thank you.

4 Power Train problem

Failure Date: 10/26/2023

The initial problem was a defective shifter. It took over a month for a Chevrolet service department to get the vehicle in and fix the problem. By the time I brought the vehicle in to fix the shifter, the transmission was hesitating to switch gears, jerking at highway speeds and overall failing to shift and accelerate properly. This high speed jerk causes the seatbelt to lock up and hit my chest-causing pain while driving. This defect has caused pain, soreness and stiffness in my chest and neck. Dealership 1 (coggin Buick GMC of orange park- jacksonville,FL) was notified upon drop off and did not fix the transmission issue. They claimed the only issue they found was the shifter. Dealership 2(gordon Chevrolet- orange park FL) has made 3 attempts to locate and repair the problem and were “unable to duplicate the concern ” I have additional documentation from dealer 3(carmax jacksonville west-jacksonville, FL) where they have duplicated the concern 3 times on a 1 hour test drive. Chevrolet/general motors are not taking accountability despite the vehicle still being under warranty.

5 Power Train problem

Failure Date: 09/15/2022

This is the 3rd time this has happened in our vehicle, my second complaint here. I was driving on the interstate at posted limit of 60 when brakes began locking up on me. I got it off to the side of the road, I thought my car was going to flip over the brakes locked down so hard. Service stabilitrak light came on, abs light and traction control light came on. I called the dealership who told me onstar provided the stabilitrak code for it. They told me it would be 160 to have it hooked up to diagnostics, that if it isn't covered by warranty it is a customer assumed cost. My husband replaced the ignition coil and spark plugs thinking that it was the problem, well over 200. 00 for parts. The car is now doing the same thing, but I noticed it happened an incline, then realized it happened the 1st and 2nd time on a decline. I am now wondering if the transmission isn't going out at 47,363 odometer miles. The dealership is no help, they have the actual codes but won't provide them or tell me what's wrong. All I know is that for a 25,000 k car, it's dangerous. I am lucky I was able to maintain control of the vehicle on an interstate highway.

6 Power Train problem

Failure Date: 09/15/2022

My car brakes locked down while I was driving home from work, at 70 mph, posted speed limit. I got it to the dealership, it started out that it was a broken wire, now they tell me I need a new fuse box and it's not covered. My car was purchased in may of 2020 and has 47k miles on it. The repairs have gone from 412. 00 dollars, not including the tow bill to 719. 00 dollars, not including the tow bill. A fuse box shorting out at two years old, and locking down the brakes is absurd. I work at a trucking company and have 40+ years experience with no tickets or accidents, I don't know how my car didn't flip forward it stopped so hard, it's hard to think about what would have happened to someone with less driving experience than I have trying to control a car in the same instance. Please check on this, if you need to know, my car is now at don hall Chevrolet in ashland ky, ph. 606-618-9616, my car is in their service center.

7 Power Train problem

Failure Date: 08/25/2022

The vehicle looses power and jerks like the transmission is failing. It happens almost always when when going up a hill and also if the air conditioner is turned on the car can barely get out of its own way. I've almost been hit or rear ended several times trying to merge onto the highway because the car is jerking and barely wanting to move. I have now come to the point that I have to turn the ac off in a brand new car for for my own safety and to be able to get up to a normal speed when merging onto the highway. It has been doing this since I first got it but I didn't think there was really much I could do about it. I plan to call the dealer as well to have them look at it. There have never been any warning lights or any diagnostic issues detected but believe me a problem is there! ive recently learned that the issues im having with the jerking and barely any power when trying to accelerate has been a big issue in the Trax since 2016. And I can confirm its still happening! there were also a few instances with a warning light on the dash and it will tell me it can't detect something in the key and I couldn't start the car until I was able to get it to read properly after a few tries of removing the key. If my vehicle is needed for inspection, it is available at anytime!.
