Steering assist is reduced Drive with care

- Laplace, LA, USA

My vehicle was diagnosed with a faulty thermostat, specifically that the thermostat was sticking and needs replaced. My vehicle is at approximately 59,150 miles as of 12/27/2023. Prior to the diagnosis of the faulty thermostat, I intermittently received a warning message "Steering assist reduced - drive with caution", the thermostatic fan would run at full speed, and the P0128 check engine code was illuminated. These symptoms began approximately at the beginning of December 2023. The problem was confirmed by a certified GM dealership service department.

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.

I looked online and a lot of Chevy products are having this issue. Something will pop up saying limited driving assistance then your cold hot gauge doesn-??t work is get stuck your air conditioning quits working your oil gauge quit working your battery how much voltage you have quits working it falls your whole window up where you can-??t see. This is an ongoing issue with most of GMC vehicles, especially blazers. This is a safety issue that could cause your car to blow up or your windows. The fog over where you can-??t see and you have a wreck and I could kill you.

Initially received Stabilitrak dash warning when brakes were applied for longer than 30 seconds (ie., stop light) for several days with no SEL. Then, while driving along a secondary highway at approximately 60mph, all dash lights lit up, power steering failed, power brake assist failed, and vehicle started stumbling. Pulled to side of road and vehicle shut off. Performed restart and was able to complete drive home (approx 3 miles). Upon arrival and shutting off vehicle, all dash lights illuminated then shut off. Vehicle would not start after (no click, no turnover, indicating failed battery). Attempted to charge/maintain battery but battery charger indicated sulfated battery. Multimeter showd 7.5V. Replaced battery and car started normally but all computer functions were reset to factory defaults. The failure of the power steering and brakes due to a faulty battery is an extreme safety issue. The fact that the battery is only 3 years old and internally corroded to the point it can't be charged is both disappointing and an additional safety hazard.

1. The power steering (confirmed by dealership) is causing vehicle to pull very hard in one direction 2. Something fuel related does not allow my car to accelerate properly. Foot will be on the throttle and accelerating and without moving the throttle the vehicle will slow, RPMS will drop then suddenly begins to accelerate again. 3. Car states it-??s not in park after I shift into park.
