The contact owns a 2020 Chevrolet Trax. The contact stated that while driving and making turns, the steering wheel had to be turned to the intended direction completely for the vehicle to turn as needed. The contact also stated that while driving and depressing the brake pedal to come to a complete stop, the vehicle failed to respond as intended, causing the braking distance to be extended. The vehicle was taken to the dealer, where it was diagnosed that the front passenger's side lower control arm had failed due to defective factory assembly. The dealer replaced the lower control arm, and the vehicle was repaired. Additionally, the contact stated that the A/C system was inoperable, and the infotainment system screen was significantly hot and turned off intermittently while driving. …

This is the either 5th or 6th complaint for this vehicle. I am making after almost 6 months, most of which my car has been in the dealership. The brakes locked up in the parking lot at my bank, I noticed the signs that it was about to lock up and pulled into the parking lot before it threw a code. I was in fact on the phone with the dealership when it happened. They sent their tow truck and as of today the car has now been in their possession for 3 weeks. I got a call from the dealership telling me they are replacing the brake booster. This car now has over 2,700.00 in new parts, this doesn't count the labor cost. This includes, coil pack, plugs, master cylinder, fuse box, abs module and related pressure valve and brake switch. The manager said they are running out of ideas and parts to replace. …
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. …
The exterior lighting system failed due to a severely eroded rear license plate wiring harness and a damaged, melted electrical connector piece, causing the connected lamp assembly (GM Part 13502178) to fail 7 separate times. Total failure of the rear illumination reduces nighttime vehicle visibility to other motorists, increasing rear-end collision risks. Furthermore, the eroded, melted harness creates an un-fused short circuit risk, posing an ongoing thermal/fire hazard inside the rear bumper. The failure loop was officially reproduced and confirmed by Hertrich Chevrolet on September 29th, 2026. Two other Hertrich Chevrolet dealerships had replaced/ repaired this part and they clearly misdiagnosed the core electrical issue six times previously by only replacing the plastic housing. …
My full complaint of the 2020 trax after buying brand new and only I as the owner and driver. Nov 2023- seat belts would not stay latched. We found out slamming on the breaks for a tractor trailer that flipped in front of us on 495. February 2024 - dash screen out, on and off as it wanted. February 2024- Heat and AC control not turning like they were super glued March 2024- dash screen out again complete black out April 2026- strut replacement @60,000 miles April 2026- water pump coolant leak April 2026- 3 serpentine belts in 3 days. I think that's all the consumer needs to be aware of, make a logical choice but the extra warranty it will save you I promise. All items have been covered by warranty, extended warranty or special warranty coverage. Make sure you research. And definitely make sure your dealership upholds their word and warranty. …
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. …
The touch screen on the front dashboard and the interior lights get so hot sometimes that you cannot touch them. Definitely an electrical issue causing both of those issues. Part of the air vent next to the touch screen has actually melted from the heat! Also, you cannot drive with the air conditioner on. The car gets no power at all. Just to go 30 mph, you have to go all the way up to almost 5 RPMs. The only way to cancel this out is to pull over, turn the car off and than back on (with no AC on). All summer long it has been doing this... possibly a transmission issue. I've personally only owned the vehicle for 2 yrs and the year of the car is a 2020, so there's no reason it should be doing this. There is no exact date. It happens all the time, so I'll just put the beginning of the spring
