2020 CHEVROLET BLAZER Complaints

To whom it may concern, I purchased a new 2020 Chevy Blazer from the dealership five years ago. Since then I have had to replace my battery twice, radiator and now the thermostat all of which have been done at the dealership. The car and all receipts of the repairs are available for inspection if requested. This most recent mechanical issue with the thermostat included the following; fans blowing on high, no AC, check engine light, steering assist reduced message, and temp gauge on C. The car was immediately (same day) taken to the dealership for investigation. Upon inspecting the car the mechanic found the thermostat sticking open and indicated that it would need to be replaced as it was unsafe to drive. A total cost of $1400. It seemed odd that my car is only 5 years old with 75k miles and needing to have the thermostat replaced so I started researching this issue further. I found several complaints on the www.chevyblazer.org forum from other 2020 Chevy Blazer owners with the same mechanical issue. There is one comment on the forum from a mechanic stating that this issue is caused by a faulty wire harness and will continue to cause similar issues until the wiring is fixed. You can find those comments in the forum on www.chevyblazer.org This continues to be an ongoing issue with this make and model of Blazer with no consistent fix from the dealer. I believe my previous battery and radiator issues are all related. I am reaching out to you for assistance and/or guidance to help get this mechanical issue reported as a recall by the dealer and properly fixed at dealer cost. I am happy to provide any additional support you may need to research this further. Thank you in advance.

Blazer was brand new purchase, I have experienced the following issues so far (several issues appear to be common based on internet searches): 1. Oil pan replaced 4 years 2. Thermostat replaced around same time, this impacted steering 3. Today I replaced a transmission seal for $600, looks like a recall was issued on bolts, my vin was not in population 4. At todays appointment was told the radiator is leaking and I will need a new radiator.

Coolant temperature would not read, steering assist malfunctioning, air conditioner intermittent. Wiring harness for sensors loomed together with coil pack wiring interrupting signals.

Engine fan stuck on high, air conditioner does not work, temperature gauge stuck on cold, driving assist warning light on.

I have had to replace the radiator 3 times since I've owned this vehicle. I see where there are others with the same issue. Now I have to replace the thermostat my first radiator was replaced at 16k miles. This is a safety issue because my car over heated and broke down on the highway left me stranded

At 41,024 the AC comoressor locked up. Took it to a repair shop. Then a year later the "steering assist light" came on. Took it to repair shop. Couldnt duplicate because it would start woring again. Had heat sensor replaced. That worked for a bit. Then it did it again. Replaced thermostate. That worked for a little bit. Then the Overheated light came on. Told me to shut the car down. (I had only drove 1/2 mile. Get out....nothing! No leaks coolant good. Had it towed to a shop And just had the thermostat changed again! Im not going to find out what happens next. I got ine more patment in tgis thing and Im trading it in. Its not a trustworthing vehicle for a single lady. Never buying a chevy again. I cannot wait to get it off my hands! 2 years everything started having issues.

COMMON ISSUE, The steering assist is reduced and temp gauge is stuck on C. This either a thermostat or temp sensor issue.

When putting the car in park the car don’t recognize it’s in park cause the car to stay running.

Chronic code P0128, causes cooling fans to go on high, AC doesn't work and steering assist reduced. GM calls for the thermostat to be replaced, at the cost of $1400 at my local Chevrolet dealer. Worked fine for two months then code and issues come back. Online forums are full of people with the same problem. Clearly there is an issue with these vehicles with the 3.6l motor.

Cooling ran would never shut off, 'Steering Assist Reduced Drive with Care', the smell of sweet syrup (coolant), and the temp gauge would not leave 'C'. All of this happened at once. Brought it in as it was subsequently throwing codes. Chevy Heiderbrecht dealership said that the radiator seal at 53k is completely eroded away and needs to be replaced. They said this is a very common issue with these cars (2020 Blazer/Original Owner), and looking online there is a plethora of people with the exact same issue (low mileage, complete radiator replacement due to seal going bad on upper driver side). This is insane, you spend 40k on a car, maintain it well, and the parts fail this prematurely with no available recall? Now I am stuck with an $1,800 bill with no legal recourse? I mean the dealership said it is a widely known issue, and GM has admitted that the seal is bad, but there's no consumer protection from this big of a company? Only thing covered under powertrain warranty is the thermostat (wow thanks GM!) Thanks for any help you can provide.
