Hi My wife arrived home from work and put the truck in park. A message came up on the instrument panel saying shift to park and would not let her shut the vehicle off. I went out could not figure out what was going on because the truck was clearly in park. After moving the gear shift around the message went away and I was able to shut off the truck. A couple of days later when she got to work, it did it again. Moving the gear shift around turned it off. I took the truck to the dealer 10/18/23 and inquired about a recall for this because so many people are having the same issue, on several GM makes. No recall and I had to pay close to $572.99 for them to replace the gear shift assembly. We just bought the truck in Feb of 23 and paid cash. $300. At time of purchase the truck had 21000 miles. Today it has only 24000.

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.

When the vehicle has physically shifted to park and the push to start/stop has been engaged, the dashboard will light up that the vehicle needs to be shifted into park.

After shifting into park the DIC comes on and says shift into park. At first I was able to reset the transmission into drive and back to park and it would reset the DIC. However, today I was at a loss as what to do as it would not reset and the lights and horn were in a warning mode. Finally, I set the parking brake and the DIC message went off. I have not gone to the dealer but will make an appointment to do so. Our 2019 Blazer only has 18,500 miles on it when this happened. I have seen several complaints of this type when researching the problem. No simple solutions were offered other than a trip to dealer for an expensive fix.

When shifting to Park, and pressing the button to turn the car off, received an error "Shift to Park" despite being in Park and the car would not turn off. When researching the issue, many others have reported the same issues with other models of Chevrolet and GM vehicles. This is a known issue and GM has issued a service bulletin, but not a recall. I went to Reedman Toll Chevrolet in Langhorne, PA where I purchased the vehicle. They are also familiar with this issue as many others have experienced the same error. This was also an expensive fix for me out of pocket. It cost $660.

When I shift my car to park and turn it off the dashboard will alert me and say I need to shift to park. The car doesn-??t recognize I just shifted into it, but it automatically unlocks my doors so part of it knows I-??m in park. I-??m not sure if I let my foot off the brake if it-??ll start rolling & I haven-??t attempted since it-??s usually in my garage. It is currently at the Chevy Dealer to be -??analyzed-?? but it seems to be a known problem they don-??t want to recall.

When I shift to park it doesn't recognize its in park along with extreme stutter of the transmission when accelerating this could be dangerous as it could result in a accident.

This is less an incident and more like a concern. I noticed a slight shudder upon accelerating. It started at lower speeds, approximately 25-30 mph, and shifting between second and third gear. Now with daily driving, the shudder has progressively gotten worse. It now happens at higher speeds, approximately 50-55 mph, and has become more violent. There is also now an acceleration and deceleration issue whether my foot is on the accelerator or I have the vehicle on cruise control. After some research, reading several service bulletins and forum posts, I have learned that the problem component is the torque converter in the transmission. Chevrolet is aware of the problem and has issued a service bulletin, PIP560C, recommending a drain and fill claiming that will fix the problem. I had this done in accordance with the bulletin, and it only made the problem worse. After talking with more than one mechanic, I was told that if this problem is not fixed, the vehicle could stall and the transmission could lock/seize up. This could present a safety issue by posing a potential cause of an accident if the vehicle stalls in the middle of a highway or busy street. This issue also can potentially cause further transmission failure.

Shift car to park keeps showing up even though I am in park.

- Wind Lake, WI, USA

When Driving the vehicle, usually around 1500 rpm, you feel the transmission start to stutter, and during this stuttering, the whole car shakes violently. this violent shaking occurs on the highway with speeds of 70mph and over. the shaking causes the steering wheel and lane centering function to become disoriented, hence almost causing me to get into an accident on the highway. This is not an isolated incident for my vehicle only. I am in a chevy 2019 blazer group on facebook and dozens of members have experienced this same exact issue. the members that got it repaired had to have the entire transmission replaced. apparently it is an issue with the gears not fitting properly and grinding causing shavings to get into the the transmission fluid causing the danger. I have addressed this issue with the chevy dealership i bought it from but the refused to document it or take accountability for the issue.

I am experiencing the well know -??shift to park-?? issue.

My 2019 blazer when stopped and put into the park position would say on the dash shift into park so you didn-??t know if it was in park or not, also it would not turn off the motor would stop but none of the electric would turn off until the battery ran down. Not knowing if your car is in park or not is a big safety issue and GM is well aware of this problem on many of its vehicles.

My car has a shudder when it is cruising at 1500rpms. It is extremely annoying to drive when it feels like I am driving on rumble strips. I have had it in the dealer 4 times and they cannot or will not fix the issue. I have filed a lemon law claim and I am hoping to get it resolved that way.
