Consumer Reviews for the Chevrolet Blazer
Read recent reviews for the Chevrolet Blazer
Pros and Cons - Blazer AWD Premier 6 cyl,
Larry Abas, 07/31/2021
2021 Chevrolet Blazer Premier 4dr SUV AWD (2.0L 4cyl Turbo 9A)
About Me:
I'm 6' 3", my son is 6' 7". We look at GM as brand that supports tall drivers and passengers. I want a car that has safety features especially automatic braking, high resolution backup camera, and wide enough that 2 adults can share the center arm rest. ( I hate theaters with shared arm rests). I rarely tow, but want the option. 4WD is must in Canadian Winters. A heated … steering wheel is a must for me. If your hands feel warm, the rest of you does too. Remote start should preheat or cool the cabin, not just start the engine. I look for a vehicle that has good handling and precise steering and no torque steer at low and medium acceleration. In 4WD no torque steer should be noticeable at high acceleration. Tech integration is important to me.
The cons:
The head room in the back is low for my 6' 7 son, he can fit a bit squashed. The adjust-steering wheel button on side of steering wheel can be hit by a tall persons knee causing the steering wheel to lower and crush knee. Two memory settings with 3 drivers is a problem. Lastly, the passenger side wiper pivots from the center of the car, leaving a "blind spot" for tall passengers. (I prefer pivoting from the edges which has better coverage. 21" tires are a bit noisy on bumpy roads. Doors don't automatically relock if you accidentally pocket-press. (yes option to auto-lock is selected). Hands free rear hatch open, often takes 2 try's of foot waving. The memory settings need more features to understand my wife and I like different display options. OnStar day-to-day use with a 10 minute response time is too slow to be useful. The SD card slot in a user accessible area with map data makes no sense to me. My SD card shows an error and after 1 month still trying to get a service appointment, was fixed with a new SD card.
The discovered good:
Gas mileage for me was better than sticker using adaptive cruise control on the highway. Engine changes to 4 cylinders when 6 are not needed. The twin clutch with torque vectoring pulls you through corners on the highway is so extremely satisfying, making you feel like you are driving on a banked turn. The rear head rests have tilt buttons on them, so that they don't hit the front seat when folding the rear seats down. All windows can be lowered from the remote ( just not raised). This helps as you approach the car on hot days. The wireless android auto and wireless charger are musts for my wife that hates wires and mess. Tested with iphone XR, and Samsung S21. Room for charging 2 phones would be nice though.
The Vehicle's Amazon Echo is functional via cell phone without an OnStar data plan. This is handy.
I have not had to clean the rear camera often. The automatic cleaner does the job perfectly. The headlight beam pattern is interesting. On my garage door this shows that light is projected in the most intelligent way with a hard horizontal line. I suspect these will perform well in fog and reduce light into the eyes of oncoming traffic. The seat cooling works but fan can be a bit noisy on high. Sun Visor vanity lights are soft-start, giving your eyes time to adjust.
The awesome must-have features once you try them:
Adaptive cruise control is amazing, its faster reacting than me, but controls speed much like I would.
The must have haptic seat for alert warnings is so much better than beeping, especially when having conversations. It alerts you to the direction of the hazard. I want one of those for my XBOX.
Rear Cross Traffic alert, sees things before I do.
Hotspot access - I can connect the Blazer to my homes WIFI network, or to my cellphones hot spot.
Bose Speakers - excellent HQ sound for streaming from phone. Sirius radio sounds flat and unappealing to me.
Additional items after 8 months of ownership:
The 4 wheel drive and handling in deep snow, 4 inches with a few 16 " snow banks to cross, was great with no notice pull to either side when accelerating or braking.
Automatic braking works well, my wife has tested it 3 times!
USB MP3 play back works great and saves some bandwidth
The electronic parking brake works well, the main advantage is that no pedal or hand-lever needed, making more space available for your feet or console.
Zero issues with the wireless phone charger, unlike my Chevy Cruze, which never worked with anything.
Garage door open buttons do no light up, making them hard to find in the dark.
More testing needed:
Tire Fill Alert: did not beep when adjusting tire pressure resulting in over inflation. More testing needed, perhaps the pressure has to be lower first.
Small issue with music streaming from my cell phone, with music pausing ever other second. This needs more testing and was cleared by turning the phone's WIFI on and off.
Features Desired:
Auto Tilt mirrors for parking. The car is wide parking spaces are not.
2 more loops at rear hatch to hang cargo net with 4 tie points.
hooks that attach to cargo organizer bar to hold shopping bags.
Cheap 21" winter rims.
Brighter day time running lights.
Paddle shifter or equivalent for downshifting before passing.
Ejection seat on wife's side.
