2021 chevy blazer problems

Common problems: Brake problems, engine problems, electrical system issues, and transmission problems. Four recalls have been issued for the 2021 Chevy Trailblazer.

The first was for tires missing information, the second for missing front seat bolts, the third for a missing brake sensor, and the last for the emergency jack that comes with the vehicle being fragile.

Consumers looking to purchase a new car may find themselves overwhelmed by the amount of information out there about any particular make and model of vehicle.

This article will summarize the information available so far from websites like the National Highway and Traffic Safety Administration (NHTSA) or the Kelley Blue Book. We will also go over how you can use the lemon law to be compensated for the purchase of a defective but warrantied vehicle.

Common 2021 Chevy Trailblazer Problems

  • Brake Problems: Total brake failure, brakes bottoming out without engaging, brakes squealing and squeaking, ABS problems
  • Engine Problems: Reduced engine power, overheating, gas odor in cabin
  • Electrical System Issues: Malfunctioning door locks, vehicle does not recognize it is in park, speaker crackling, auto start/stop not working properly
  • Transmission Problems: Turbo failure, failure to stay in park, sudden shifting into park

2021 Chevy Trailblazer Brake Problems

Brake problems are some of the more impactful and dangerous for a vehicle to have, as functioning brakes are obviously necessary to properly control a vehicle.

In the 2021 Chevy Trailblazer, consumers reported total brake failures, the brakes bottoming out without engaging, the brakes squealing, and problems with the ABS. Squealing brakes were reported overwhelmingly more than the other issues, which is generally good as it is the least severe one.

If you encounter any problems with your brakes, the vehicle should be taken in to be inspected and repaired as soon as possible, and driving with that vehicle should be minimized.

Chevrolet issued a recall for a brake sensor that was not communicating properly with the electronic brake boost system, which could result in delayed braking. This recall was issued in September 2020 and impacted 3,677 total vehicles. The NHTSA Recall ID is 20V588.

2021 Chevy Trailblazer Electrical System Problems

With how many electronics are in modern vehicles, it should be no surprise to a consumer that some of these systems can break and cause problems for the vehicle owner.

Consumers who own the 2021 Chevy Trailblazer reported problems like malfunctioning door locks, the vehicle failing to recognize itself in park, speaker crackling, and the automatic start/stop function not working properly.

Some of these functions are not necessarily dangerous, but the vehicle failing to recognize itself in park and the automatic start/stop function not working could be dangerous to the driver and for other drivers on the road.

2021 Chevy Trailblazer Transmission Problems

Transmission problems typically lead to a vehicle having problems with acceleration and deceleration. This can be dangerous because drivers should be able to control their vehicles to the greatest degree possible, and unexpected deceleration and acceleration can impact the other drivers on the road.

For the 2021 Chevy Trailblazer, consumers mention their turbo failing, their vehicle failing to stay in park, and sudden shifting into park related to the latter problem.

A vehicle failing to stay in park, especially if parked on a hill, can be extremely dangerous. A vehicle which suddenly shifts into park can be similarly dangerous, if it takes place while the vehicle is in motion and is supposed to be in motion. Transmission problems should be addressed with a mechanic as soon as possible once discovered.

    • com Complaint

    “Purchased this vehicle brand new in September 2021. I put too many miles on it for any warranty or lemon law to apply but its become unsafe to drive! The screen comes on but stays blank and sometimes a random, extremely high pitched buzzing sound comes out of the speakers but is not able to be controlled by the volume. None of the radio buttons do anything. I think somewhere (not from any windows) rain water is finding its way in to the car and the electrical components because the issue coincided with another less annoying issue of extreme condensation build up on the insides of the windows when it sits for a few hours/overnight when it rains, despite all of the doors and windows being completely shut.”

    • NHTSA Complaint

    “We purchased this 2021 Chevrolet Trailblazer RS new from the dealership and we noticed on the second day of owership that the brakes were “squealing”. The dealership initially inspected the vehicle asap and without having to go through the service department. However, the problem not only continued, it persists to this day. Additionally, we just purchased a used 2023 Chevrolet Trailblazer RS (with under 10,000 miles) and are experiencing the identical issues with the brakes squealing.”

    Legal Solutions for Your 2021 Chevrolet Trailblazer Problems

    The lemon law process is a vital mechanism for consumers who have purchased defective vehicles still under the manufacturer’s original warranty. This law provides a structured path for seeking a remedy, i.e., a replacement vehicle or a refund.

    The initial step involves taking a defective vehicle to an authorized manufacturer dealership for inspection and repair. If the defect persists after the initial repair, subsequent repair attempts are necessary.

    Typically, two to four repair attempts are required to meet the “reasonable number of repair attempts” standard set by the lemon law. Additionally, a vehicle that remains out of use for a cumulative total of 30 days due to repairs may qualify as a lemon.

    Documentation is critical throughout this process. Consumers should keep good records of all repair attempts, including dates, issues reported, and the outcomes of each repair in order to strengthen their claim.

    Once it becomes evident that the vehicle is likely to be classified as a lemon based on the persistent defect or extended out-of-service duration, the consumer can proceed to with a lemon law claim against the auto manufacturer.

    At this stage, hiring a lemon law attorney is highly advisable. These attorneys specialize in state lemon laws and can significantly enhance the consumer’s chances of success.

    In California, if the consumer wins the case, the manufacturer is responsible to pay for the consumer’s attorney’s fees and costs thus ensuring that the legal process incurs no personal cost to the consumer.

    Upon a successful lemon law claim, consumers are entitled to either a refund or a replacement vehicle. The refund includes the reimbursement of the full amount paid for the vehicle, potentially covering incidental expenses such as rental car fees or registration renewal costs as well.

    Alternatively, the manufacturer may offer a replacement vehicle. In both scenarios, the manufacturer may deduct a fee for the period during which the vehicle was operational without issues causing it to be a lemon.  With the replacement option, the consumer will be responsible for any difference in price.
