I drove my parents trailblazer for 2 years covering approx. 300 miles a week going to tech school with 160,000 miles on the vehicle already. I put on about 30,000 miles in total. This vehicle had the original spark plugs and boots in it and started giving me issues at about 186,000 miles. It NEVER stranded me. That on it's own, makes it an amazing vehicle. The only other parts I had to get replaced was a transmission line that rusted out, idle pulley belt, brakes/calipers, and the spark plugs and boots. Highly recommend this beast of a suv.

I bug this car in the last 10 years and I love it. I put 220,000 miles. But the engine star to give me problems, if some body can tell me we're I can fine a engine please

I love the trailblazer but the issues that have come up and the research I've done I'm surprised how many people own. The first 6yrs of owning it was outstanding. Now I feel like it's a money pit. It get regular maintenance on oil changes and tires when needed. Check engine light has been on for 4 yrs. We have checked and changed what the code says and reset it but still on. I've lost my lights while driving the heater works sometimes. Changed and fixed what it was and still acts as if there's electrical problems. Battery gauge fluctuates and my lights also. Just installed new alternator. That's the 2nd one in a year lights and heater still fluctuate.
