The 2020 Chevy Blazer is considered an iconic SUV with its stylish good looks. Even the automaker claims this model provides “style, with plenty of substance.” However, customers are finding it comes with much more than what they bargained from, from the defective service brakes to the faulty electrical system and malfunctioning powertrain.

No one wants the service brakes in a vehicle to fail. If they do, an accident is imminent. Yet, customers driving the 2020 Chevy Blazer are regularly facing some serious concerns.
One NHTSA complaint states, “I was driving about 35 mph going straight when my Chevy Blazer acted as if it hit a brick wall and came to a complete stop. I got out and noticed my right front wheel was completely smashed into my car. Something had come loose internally and locked up my wheel. It damaged my car so bad where my suspension was damaged. It had to be towed. It was non-drivable. My vehicle only had 1300 miles on it. I decided at last minute to not get on highway.”
It turns out this Chevy has massive recalls that are also causing some big problems. NHTSA Campaign Number 21V115000 says that some of the tires were cured too long, which can result in sudden air loss or belt edge separation and a sudden loss of control. If this happens, everyone hopes the air bags are working, but NHTSA Campaign Number 20V446000 states otherwise. This recall points out that the Roof-Rail air bag might not be crimped properly, causing a separation, which prevents the air bag from deploying. At this point, it would be fair to say the Blazer is suffering from “a lack of substance.”
Vehicles must have properly working electrical systems to keep occupants safe and create an enjoyable ride, but this Blazer fails miserably.
Another NHTSA complaint states, “Twice while I have been driving, the instrument panel went black. In motion.”
It’s very hard to drive with no access to the speed of the vehicle, how much gas is in the car and the other valuable data found on this gauge. However, this isn’t the only issue the Blazer is facing. A class action lawsuit in Florida claims that 2020 Chevy Blazer models have a defect that causes the sound volume of the stereo to max out with no input from anyone in the cabin. This sudden and loud noise can cause an on-road safety hazard, leading to possible accidents. Apparently, Chevy wants to make sure everyone hears loud and clear that it makes a stylish SUV.
Finally, a look at the Blazer powertrain reveals some alarming issues. What’s even worse is this isn’t a cheap car that’s being discussed, but it would appear to be built like one.
An Edmunds user stated, “”The wimpy 1500 lb towing capacity means that the transmission might give up and quit soon after the warranty period is up. The top models feature a 4500 lb towing capacity which means better cooling apparatus on the transmission so it should last much longer. By contrast the entry level Nissan Pathfinder can tow 6000 lbs with its CVT transmission. It’s not just about pulling boats or campers. It’s about investing in a vehicle that could last for 500k miles and get handed down to your kids. But make sure you always take any Nissan only to the dealer for transmission service. CVT transmissions require special fluid and many shops end up adding regular transmission fluid resulting in premature failure after a few days of driving. If you mainly lease your vehicles for shorter periods of time and are getting into the Chevy Blazer mostly for its drop dead GORGEOUS looks, then the life of its tranny might be of lower concern. However if you do opt for the entry level model with long term ownership in mind, beyond 100k miles: consider your extended warranty options. Transmission replacements cost thousands.”
It turns out there have been recalls for the powertrain too. NHTSA Campaign Number 20V668000 affects nearly 200,000 vehicles and states that the start/stop accumulator endcap might be lacking some necessary bolts that should have been installed at the factory. These missing bolts could lead to a transmission fluid leak and a loss of propulsion, increasing the chance of a crash. What’s worse is that anytime fluid is leaking, there’s an elevated chance of a car fire. Sadly, most owners probably wish that their Blazer would go up in a blaze of glory right about now.
Think you have a lemon? Sit back and let the experts work out your lemon case at no cost to you. The law makes Chevy pay legal fees. You may be able to get your lemon out of your life. Every year, auto manufacturers buy back, replace or pay cash settlements to thousands of ‘lemon’ owners like you.

Description | I pulled in my driveway which is on a slight incline. I turned the vehicle off but the transmission was still in drive. Not realizing this I stepped out of the vehicle and the vehicle started rolling back down my driveway across the sidewalk and into the street. Had there been anyone walking on the sidewalk the vehicle would have hit them or there could have been an accident in the street. I called the dealership where I got the car and and all they could offer was that you're not supposed to turn off the car in drive. I know you're not supposed to turn the vehicle off in drive but it happens and has happened several times to me and I'm sure to others also. I think this is a major design flaw as I have seen that on ford vehicles when you turn the vehicle off in drive the transmission automatically goes into park. |

Description | On tuesday august 9, 2022 at 0800, I dropped off my 2020 blazer. I informed the staff that the seat base was not cooling as well as when I bought it, something is wrong with the transmission, and the screen keeps freezing. I was informed at that time by amanda carroll that it may take up to 72 hours to perform a diagnostic on the blazer due to only one diagnostic tech at this time. The diagnostic had not been performed. We then told her that I had to return to work on monday august 15th, can we get a loaner vehicle. We were told that due to the shortage in microchips, they did not have any vehicles available. âI am sorryâ. We had not heard anything from anyone in regards to the status of the blazer, so we went in person to the service department on saturday august 13, 2022 at 1130. My husband then asked about the status of the blazer, was a diagnostic performed? She informed us, that a diagnostic was not performed. The only diagnostic tech called out, but he did come in on his day off to help. They know something is wrong with the blazer, but were not able to perform the diagnostic. I then informed her that it has been over 96 hours since I dropped off the blazer, and nothing had been done. I have to make a choice of driving a possibly dangerous vehicle or lose my job. But since a diagnostic was not performed, who knows what is wrong with the blazer. I was informed from the bbb to contact sean jordan at all american chevrolet of killeen to discuss this matter. I contacted mr. Jordan and we made arrangements to have the blazer brought in on september 3rd at 0800. I took the blazer into chevrolet at 0800 and was informed by the employee, that I only had 45 miles until my warrantee was out. I told the staff employee, when I turned in the blazer last month, I still had a warrantee and that mr. Jordan would have to take care of that issue. Nothing was done and we left. I am out of characters to finish the complaint. |

The contact immediately attempted to stop the vehicle from rolling into the neighbor's home by grabbing the driver's side mirror. The contact was able to prevent the crash from occurring but in the process had sustained injuries to the left shoulder, neck, and back and both the left and right hip and knees which required medical treatment.

Description | My retractable sunroof suddenly explosively broke. I was approaching a red stop light at low speed. I heard what I thought was a gunshot or vehicle backfiring. As I drove on, I heard wind whistling. I thought my passenger side window wasn't closed. I lowered then jraised it. At that point, I heard my sunroof disintegrate. Luckily, the headliner kept the glass from raining down on me. If this had happened at highway speed, it could've been a real problem. |

Description | New 2020 chevy blazer awd premier with oem continental crosscontact lx sport tires in size 265/45r21. Car has 18,000 miles on it and tires have been rotated and inflated correctly. All 4 tires have tread depth near 2/32 and need to be replaced per tire shop. Come to find out this continental brand of tires has no treadlife warranty at all so they don't even believe in their product. How can chevy and continental be allowed to put this tire on new cars to rip off the consumer. I'm going to have to buy 4 new tires on a car that has 18,000 miles on it. This should not be happening. It's also a safety concern for others on the road that aren't aware they need to check their tire tread depth so soon with these tires. |

Description | With approximately 1500 miles on the vehicle, the blazer's automatic transmission failed while driving. I was stopped at a red light. When the light turned green, I proceeded slowly through the intersection in a left turn. As soon as I left the intersection, just as the vehicle would typically up-shift, the rpm spiked, the vehicle jolted forward, and the check engine light came on. After the initial jolt, the vehicle would not shift out of first gear. I found a safe place to park and stopped the engine. Upon restarting, the engine light remained on and, though I could put the car in drive, the vehicle would not shift out of first gear. Moreover, when I tried to engage reverse, the car remained in neutral. I had it towed to a chevrolet dealership which informed me gm has a bulletin on the transmission requiring technicians not to attempt to repair it, but to install a new transmission. |
