Transmission doesn-??t have 3rd or 4th gear. Vehicle was smoking under hood. Found out after buying it it has flood damage. Mechanic said there was water in the transmission when inspected. Vehicle needs catylic converter sensor and vehicle has bad ground wire. Seller didn-??t inform me of any of these issues and he said it was in good shape and very reliable.

The contact owns a 2003 Chevrolet Trailblazer. When the vehicle was started, the instrument panel gauges operated intermittently. The vehicle was taken to an independent mechanic who diagnosed that the ignition switch and instrument cluster failed. The manufacturer and dealer were not notified of the failure. The failure mileage was unknown.

I have a heavy fuel runoff, from my fuel tank. Even if the engine is only ran for a minute. Also, my headlights go out whenever they feel like doing so, while driving

My daughter was driving locally yesterday 7/1/18 and making a right hand turn at a slow speed. She lost control and collided with another vehicle in oncoming traffic. She was injured. The cars brake lights had just gone out and the blower is going on and off. I assume this is an electrical problem for which my VIN is not displaying a recall. There is now damage to the wheel and rear drivers side fender, clearly displaying that the vehicle spun out of control, based on the 2 vehicle impact points.

For the last 3 years, every part of my instrument panel seems to work intermittently. At times while driving, the speedometer will show me doing 40 mph over my actual speed, or will show me doing 120 while I am sitting still. The oil pressure will sometimes show that there is no pressure at all, or the temp is as far as it can go on the hot side. All of these issues disappear after a while, and then function normally. They do not seem to be tied together, because at times several instruments are working fine, but 2 others are not.

Multiple gauges on the instrument panel are malfunctioning. The tachometer is reading 5,000 RPM when the vehicle was in park, and 7,000 RPM when going 15 mph. When I turn the car off the gauge sits at 2,000. The speedometer is clicking up (not a smooth transition to the correct speed). And it showing a lesser speed then I am going. When I turn the car off the speedometer shows it is going 10 miles per hour but will slowly drop down to zero. Both of these malfunctions could are a huge safety concern. I had to pull over on the highway while the instrument panel was showing 7,000 RPM, afraid I was going to break down and ruin my car.

All of my gauges including fuel gauge, tachometer, and speedometer have stopped working. They will work some days and then others the gauges are all out of whack. It seems to occur especially when it is cold out. I am very frustrated that this is happening. I realize that my vehicle is older, but I do appreciate working gauges!!!

The dashboard cluster malfunctions. The first time it went out, the fuel guage and oil pressure guage stopped working and all other guages went out one by one soon after. We had a new GM cluster installed by the GM dealership at a cost of $600. This time, all guages stopped working and the alert lights stay on. (I.e. service 4WD, seat belt, service engine, brake and ABS) other GM vehicles with this same cluster have been recalled but not the 2003trailblazer.

"takata recall" we just purchased this car from my husband's deceased mother's estate and it had a recall on the lighting inside and outside tail lights. The vehicle has 83 thousand miles on it and the vehicle rear lights are not working when I brake only one that is the third light on top of car. GM (Chevrolet) I live on a very limited income and due to disability as well. My income is 1330 a month. How can I get this fixed? they want to charge me for diagnostics, as I stated we fixed it once it seems to be that it may get hot and blows fuses and then I have no idea I have no tail lights this is very dangerous and someone could rear end me and kill themselves and or myself. Please help me in understanding are they responsible to fix their defects as they did it once when it was recalled and we also just bought this car. Paid about 5 thousand for it. Excellent condition. Other than the lighting system not working only on and off. I have not had an accident but I do not want to have a accident. I find it unfair that they don't want to fix the problem unless they are paid because apparently it is a problem that is and will recur. We have actually fixed the problem once but apparently something is wrong that we cannot secure the issue properly.

Electrical problems in the instrument panel (dashboard). All gauges intermittently quits working, on startup, sitting running or in motion. Tachometer never reads correctly. Can occasionally get gauges to reset by clicking ignition back and forth between run and start positions. I know of 5 other vehicle's that are having similar problems.
