2004 Chevrolet Trailblazer Reviews

I have a 2004 chevrolet trailblazer LT we purchased in 2007 we have had nothing but complications it started of minor now its major we had the transmission rebuilt and now the 4wd is bad and this was the way they sold it to my husband, we are also having the power steering pump and acurators replaced for the a/c , we have this great mechanic who is helping us with all our problems at a very low cost that is why were able to fix this LEMON!!!!

I have a 2004 Chev trailblazer. The worst item is the memory seats and settings for 2 drivers and seat heaters. They intermittently work at best. I never know when I get in the car. Seems they work about once a year then stop working for months at a time. Also the 4WD stops working--about once a year. Usually stops for a couple of days then starts working again. The On Star people said it is a sensor that can't sense. It then defaults to 2WD.

I have 187,000 miles now. Just had(2013) to replace the A/C compressor. In (2012) I had to replace and ignition coil. 2012 replaced front upper and lower ball joints in the front suspension.

Not bad if compare repair costs vs new car payments.

I have a 2004 Trailblazer that has 62,000 mi on it and my problem is that it has had 4 water pumps and 2 clutch fans installed and it is now leaking anti-freeze again. It also has a squeak/rattle in the front end when turining that has been there since new.Now the ABS light is on code says ABS pump. This is the worst most problem auto I have ever owned !! Finally it slugs fuel like pouring water out of a glass. Time to cut my losses and trade !!

I purchased my 2004 in 2006. It had approx. 60,000 miles on it. My Trailblazer and I have been from the Midwest to the far East Coast states and as far south as Tennessee. I now have 215,000 miles. I have not had any major problems until now, but in all fairness it is probably partly due to some neglect. I have within the past two months replaced both wheel bearing and hub assemblies, upper and lower ball joints and tie rods on both sides, and water pump. Despite all the repairs, it still looks and feels good to drive. Some people close to me have asked why I don't buy another vehicle with all these problems, but its paid for and I honestly think I can get another 200,000+ miles out of this boy.

I bought my 2004 Chev Trailblazer used from a rental car company in 2005. I never expected it to be so reliable and tough. I have only had one issue, the heater core went out and dumped lots of antifreeze in the interior of my car. Easy fix and it has been fine exer since. I have been thinking about getting another car but after reading the glowing reviews on the Trailblazer and bad reviews on other cars I was considering, I will keep my loyal, tough, well built Trailblazer. Thanks, Chevy!
