2003 Chevy trailblazer blew a few fuses so I could not start the vehicle (several times already), per dealer. Tachometer jumps around, radio gets hot, electrical lights turn off along with heater/cooler, rear lights replaced three times, hole in gas tank, drive line replaced, constant chirping/ticking noise (of course dealer does not hear). Purchased brand new and have way too many problems for a new vehicle. You asked for incident date....there are several. Will stick to Toyota's from now on....

Trailblazer EXT 4WD 8-cyl

  • Automatic transmission
  • 35,000 miles
Vehicle when placed in four wheel drive, does not engage front wheels and in fact does remain in only two-wheel drive. This creates a dangerous situation because on snowy roads particularly in rural areas, for example, the vehicle can become unsafe to drive.
