Common Chevrolet Blazer Faults: Problems And Solutions!

The Chevrolet Blazer is a good choice for a sleek looking yet reliable vehicle. So it would be a very good choice, but first we invite you to learn about the common faults of the Chevrolet Blazer .

While the latest model year comes with the latest features (like added active safety systems), an older vehicle built in 2005 or earlier can give you a lot for your money if you know how to take care of it. It was reported that the price of a well-maintained Blazer depreciates by 47% after five years.

How good is the Chevrolet Blazer?

Owners gave the 2019 Chevrolet Blazer a Quality and Reliability rating of 85 out of 100 and it ranked #1 of the Top 10 Consumer-Rated SUV Models. By comparison, another set of owners gave the same model year Blazer an expected reliability score of 2 out of 5. Their overall rating is 68 out of 100.

A Blazer can easily get 100,000 miles . Following Chevrolet’s recommended maintenance schedule and being aware of any problems that arise will keep your SUV running smoothly for many years and miles.

Common failures of the Chevrolet Blazer

The original Chevy Blazer saw production from 1969 to 2005. In 2019, Chevrolet revived the Blazer as a mid-size crossover SUV. Depending on the model year, certain problems may develop with greater frequency or severity.

After evaluating both classic and refreshed designs, the 2004 Chevrolet Blazer was identified as the model year that received the most complaints overall. However, the 1994 Blazer was considered the worst model year for several issues.

Chevrolet Blazer engine problems are considered the worst category for the model . The most commonly reported problem is a bad fuel gauge, which tends to show up on the 2000 Blazer.

Here are the most common Chevrolet Blazer failures reported:

1. Fuel Pump Failure

Owners of certain 2005 Chevrolet Blazers did not appreciate how their vehicle’s fuel pump could fail. Without an uninterrupted supply of fuel from the fuel tank, the engine would stall or not start.

Some units of the Chevrolet Blazer manufactured between 1990 and 2005 developed problems with their fuel pump. Experts recommend replacing the fuel filter every 30,000 miles to help keep the pump running smoothly.

2. Distributor failures

Internal distributor defects in the 2001 Chevy Blazer could affect engine performance. Some drivers reported that their vehicle was rough or stalling, which could cause engine damage . They were forced to service the distributor or replace the faulty ignition part as soon as possible.

Other than the 2001 Chevy Blazer, the defective distributor could be found on some units produced during 1990-2005.

3. Problems with the fuel gauge

Normally, the fuel gauge keeps the driver informed about the amount of fuel left in the 2000 Chevrolet Blazer’s fuel tank. But some owners have reported that the gauge showed inaccurate readings when the fuel level sensor went bad.

Replacing the 2000 Chevrolet Blazer fuel level sensor resolves the issue in most cases. On older high mileage vehicles it is recommended to replace the entire fuel pump module assembly.

This problem was reported by people driving 1996-2005 Chevrolet Blazers . The 2000 model year accounted for the highest number of complaints.

4. Transmission failure

In some units of the 2000 Chevrolet Blazer, the transmission could develop serious problems that made driving the vehicle much more difficult and dangerous. Owners have reported issues such as gear slippage, no going in reverse, strange noises, the transmission stalling, and even catastrophic failure.

In some cases, it may be necessary to rebuild or replace the entire transmission to make the vehicle safe to drive again.

5. Anti-lock Brake System (ABS) Control Module Failure

The 2003 Chevrolet Blazer’s ABS system control module decides when to engage and disengage the antilock brakes to prevent skidding. Some drivers were very upset and concerned to learn that the reason for the ABS light was coming on was a failed control module. Even if the wheel speed sensors were working perfectly, a bad control module wouldn’t be able to issue brake on and off commands.

This problem also appeared on Chevrolet Blazer units built during 1994-1998, 2000-2002 and 2004-2005.

6. Problems with the gas cap

Even a part as simple and unassuming as the gap cover is vital when it comes to keeping the 2002 Chevrolet Blazer running smoothly. A loose or worn gas cap may not seal the fuel tank properly.

Not only would fuel vapor escape the tank and cause problems, but contaminants like dirt and moisture could get into the fuel system. Contaminated fuel would reduce engine performance and could even damage it.

A faulty gas cap could also trigger the check engine light, and it could take the driver or technician a while to locate the actual cause of the problem.

7. ABS Front Wheel Speed ​​Sensor Failure

The 1999 Chevrolet Blazer’s ABS speed sensors were always on the lookout for wheels spinning too fast, which was a sign that the tires were losing their grip on the road surface.

Unfortunately, the front wheel speed sensors showed a distressing habit of breaking down . Without readings from these sensors, the ABS control module could activate the brakes when it shouldn’t.

8. ABS system activation failure

The 1994 Chevrolet Blazer comes with ABS that helps the driver maintain control while driving on slippery surfaces. However, some owners reported that the ABS could activate even when their vehicle was moving slowly on wet surfaces. Unexpected activation could take drivers by surprise and put them at higher risk of a traffic accident.

To end

With regular maintenance and proper care, the Chevy Blazer can give you many years of great driving experience. Whether you’re a new driver or a veteran of the road, it’s worth reading up on common Chevrolet Blazer faults. They will help you prevent problems from getting worse and make the most of the useful life of your car.
