Here are the problems I've been facing: 1. Shift to Park Error: My Blazer often displays a "Shift to Park" message, even when the vehicle is already in the park position. This happens randomly and has no discernible pattern. As a result, the vehicle won't turn off, and I'm forced to repeatedly shift back and forth and apply excessive force to engage the park mode. 2. Steering Assist Reduced Message and Cold Temperature Gauge: Another recurring issue is the appearance of a "Steering Assist Reduced" message. At the same time, the temperature gauge gets stuck at the cold position, and the check engine light remains on. This seems to be a common problem among Blazer owners and requires immediate attention through a recall. 3. Fuel-Related Acceleration Problem: I've noticed a fuel-related problem that affects acceleration. The vehicle experiences sudden slowdowns, with the RPMs dropping, even when I maintain a steady throttle position. Then, out of nowhere, the Blazer regains speed and accelerates. This unpredictable behavior is dangerous and needs to be addressed immediately. 4. Random Loss of Power Steering and Power Brakes: On several occasions, my Blazer has lost power steering and power brakes without any warning. It's incredibly unnerving and puts both the driver and others on the road at risk. It's important to note that my Blazer is well-maintained and has less than 60,000 miles on it. These issues should not be happening under these circumstances. I strongly believe that these problems require the attention of the manufacturer, and I urge them to initiate recalls to rectify these safety concerns.

While driving the blazer the vehicle lost power. It was missing and didn't want to go. The warning lights came on. I had to call the tow truck to come pick it up. I had it delivered to the shop where I bought it. That was on sunday, october 6, 2019. On monday, october 7, 2019 I was called and the conclusion was made that I had a dead injector. They replaced injector #5. Picked it up on tuesday, october 8, 2019. Drove it home and on wednesday, october 9, 2019 on the way to work, I ended up on the side of the road again. The car did the exact same thing as on sunday. The car went down to 20 MPH. I was able to limp it to a parking lot. I called a tow truck again and took it back to the shop. I am still waiting on the diagnosis as of friday, october 11, 2019.
