Tl-the contact owns a 2002 Chevrolet Trailblazer. The contact stated while driving approximately 45 mph, a strong odor of fuel emitted inside of the vehicle. The engine then stalled without any warning. The gear lever would not lock into the park position until after numerous attempts. Upon restarting, the vehicle was able to resume in operation. The vehicle was taken to an independent mechanic, who tightened the shifter cable. The vehicle had not been repaired for the other malfunctions. The manufacturer was not notified of the problem. The approximate failure mileage was 160,000 . Js.
2002 Trailblazer. Engine stalls while at low engine rpm. With it in park can hit the gas and rpms will go down below 500 then recover. Has actually died once. Almost died while pulling into a parking spot. Almost died when coming to a quick stop at light. At first thought it only occured with the ac on but have declared it to do same with the ac off but not as bad. Noticed several complaints of same issue here and on edmunds. Com. Ours hasn't stalled at highway speeds but I fear it won't be long before it does and my wife is the primary driver and is now pregnant with our second child. Vehicle has been to dealer at least three times for this issue. Gm needs to put us (all Trailblazer owners) in a safe vehicle and diagnose problem nationally before someone is killed.
Engine knock and rattle on cold start, worsens when loaded (in gear). After several minutes, knocking diminishes. Coincides with intermittent cold engine stall with no ses light set.
Engine stalls after start regardless of transmission gear selected. Will restart, but is stalling after backing out into a major local raod with heavy traffic, posing a rear end collision risk.
Engine stalled while driving 60 mph. Dealer inspected vehicle and determined engine needed to be replaced due to sleeve of one piston falling off.
