CHEVROLET Complaints

I am writing to formally report a persistent and dangerous manufacturing defect regarding the rear window and seating assemblies in my 2020 Chevrolet Silverado. I have already had GM replace the rear window in 2023, it needs replaced again now in 2026. The rear window seal is failing, allowing a significant amount of rainwater to leak into the cab. Because of this ongoing water intrusion, the structural base and brackets of the rear seats have developed severe rust. Furthermore, I am deeply concerned that this constant moisture saturation is creating an unseen mold hazard within the cabin, which poses a direct health and respiratory risk to my passengers.This leak also risks damaging sensitive electrical components and wiring harnesses located under the rear seats and trim panels, potentially causing short circuits and sudden failures of critical safety systems while driving.Many other owners of this generation Silverado have reported identical issues, including cracked plastic frames around the sliding rear glass that cause the leaks. Because this defect compromises vehicle integrity, creates a risk of electrical failure, and poses health hazards from mold, I am requesting that the NHTSA investigate this issue as a potential safety defect requiring a manufacturer recall.

Car is overheating with multiple engine codes. Unable to drive. Car power is reduced and shortly after will start overheating.

Had to get engine replaced 2 months after I bought it in May 2022, warranty covered the replacement. Ongoing issues with catalytic converters, O2 sensors, check engine light coming on due to those reasons for approximately almost 2 years now. Powertrain (Stablitrak, ABS & ECO) stopped working 6 months after purchase - stablitrak warning light came on, took to dealer that I bought it from, quoted almost $900 to fix it, then took it to a private shop then had them fix it due to affordable cost, but somewhat still having some issues. Now Equinox is burning through oil fast. I can bring it in upon request via TEXT ONLY as that I'M DEAF. Those issues have put my children's and my safety at risk because the powertrain caused my Equinox to shut off in the middle of the highway going uphill and other times as I was driving with my kids. All of those need to be fixed by the manufacturer or totaled and I get reimbursed for it. Can provide receipts of repairs & quotes to repair upon request via email.

3.0 Duramax, thrust bearing engine failure. Less than 6000 miles on vehicle. Driving at 60 mph when vehicle went into major limp mode. Had TCM, Charging and coolant lights illuminate. GM is replacing engine under warranty. Indicated there was approximately a 2 week engine production window where this issue is being traced back to. GM should issue recall if they know the extent of condition and the cause(s).

As I'm driving I hear a chime and the radio says power steering and I just loose power steering it's scary and I really wish gm would have made this a permanent recall

Check engine light came on and the dealership said it was because the coolant was low due to the radiator hose leaking. I was told by the actual mechanic that they’ve had to do a lot of radiator hoses and that it is a known defect with the Colorados and the traverses but that GM hasn’t done a recall on them yet. That is what brings me here. My truck is only 2 years old and this shouldn’t be happening right now. Thank you for taking the time to review this and I hope GM addresses the matter promptly.

47,000 miles and the transmission coolant lines are weeping and need to be replaced.

All sound goes out on this truck intermittently. Maybe once every 3-4 days. I will have 0 sound, the safety feature sounds, the parking assistance, the directional signal sounds, the stereo. It is not Bluetooth or anything interfering I’ve shut my phone off to test. This happens with MANY people. Most people complain online about the stereo and directional sounds being completely muted, but forget to mention or don’t notice that the parking and collision assistance sounds are out as well. It took me a while to realize. I have video of it happening as well

While driving at any speed when steering wheel is at the 1 to 2 o' clock position on a right turn, steering wheel wobbles and regardless of road condition. Stabitrack warning light comes on occasionally.

Was driving and vehicle went into neutral and reduced acceleration drive with care message along with a illumination of a engine appeared on dash, dealer diagnosed faulty valve body on transmission
