When you start the process of looking for a car, whether it’s new or used, it’s important to research whatever model you’re interested in to see whether it will hold up for the long haul. It doesn’t matter what brand you’re looking into; every brand has its lemons. RepairPal.com offers a look at the top issues with each model, gathering data on complaints, model years affected, and more.
If you’re looking into the Chevy Trailblazer, it’s surprisingly affordable, and some great things are going for the SUV. However, there are also some common complaints and some that say it’s more of an entry-level SUV. Here are the top three complaints you should be aware of.
There is frequent fuel level sensor failure in Chevy Trailblazers
The erratic nature of the fuel gauge may not seem like a big issue, but it garnered the most complaints from consumers. Some consumers reported that the count was off, while others shared that the gauge would get stuck on empty. The issue could be fixed in high mileage vehicles by replacing the complete fuel pump module assembly.
For 2005-2007 models, GM agreed to pay for 50% of the repair costs, even though it actually affected 2002-2008 models. In general, it is estimated to cost between $787 to $1,067 to get this issue taken care of.
With 544 people reporting this problem, you can see why it’s a big deal. The average miles it occurred at was 91,740, although it could happen as low as 5,700 miles.
The AC blower is inoperable due to a failed resistor
In 2002-2008 Chevy Trailblazers around 114,075 miles, consumers reported that the HVAC blower motor would stop working at one or more speeds. Some reported certain speeds no longer working, others temperature changes, and still, others said that certain vents wouldn’t work at all.
This was due to a faulty motor resistor block and could be verified by checking the operation of the switch before taking it in for repairs. 336 people reported the problem, and it could occur at as few as 1,460 miles. The cost to fix it isn’t a high one, so this is one of the better problems to run into, if not annoying in a hot location. Estimates put the cost to replace the motor at $118 to $155.
The cooling fan clutch may fail
When the cooling fan clutch fails, it can cause excessive fan noise. Sometimes, it will cause the check engine light to come on. This repair is another cheap one, at least for the diagnosis itself, averaging at $100. Model years 2002-2007 were affected, with 227 people reporting the problem.
Chevy Trailblazer owners generally noticed the problem during acceleration, and some shared that it felt like the transmission was slipping. One consumer suggested trying to clean the electric clutch connector on top of the radiator before taking your vehicle in for a diagnosis if you experience this issue.
The average mileage this issue occurred at was around 137,191 miles, but it happened as low as 12,000 miles for some people.
Here’s what else to watch for in the Chevy Trailblazer
There were 30 total problems reported overall. The check engine light coming on due to a gas cap issue was the only other complaint that had more than 200 reports from consumers. Other issues included things like CD player failure, worn valve seats, and sticking camshaft actuators.
You can see a full list of problems on their website. If you’re in the market for a used Chevy Trailblazer, the years with the most problems reported were the 2006 and 2007 with 22 problems each. After that, the 2008 had 19, the 2002 had 15, the 2003, 2005, and 2009 had 14, and the 2004 had 13.
From the sounds of it, their debut years weren’t their greatest. At least Chevy started to up their game in 2010 and produced a much more reliable car after that. The 2021 Chevy Trailblazer is a new redesign too, so it’s worth looking into.
