Recently reported ELECTRICAL SYSTEM problems on 2003 Chevrolet Tahoe

Takata recall, today, may 31, 2019, i drove my truck to a meeting at 1:30 in the afternoon and parked my vehicle in the parking lot (it was stationary in a city parking lot). when i returned to my car after the meeting at 3:30 in the afternoon i open my car and the interior was engulfed in smoke. a component of the power seat on the drivers side started the fire. it was fortunate no one was in the truck at the time and the windows were closed. after the fire ignited and used up all the oxygen in the interior the fire burned out on it's own. i did call the fire department he had never seen anything like this before. (i've included the fire department investigators card and i can obtain a report if needed). the investigator was the one that determined where the fire started. he explained that the top layer of the seat upholstery has some fire retardant but the underside does not. you can see that the seat was burned from the bottom to the top, the electrical ...

While driving my instrument cluster stopped working pulled over unplugged battery started working but been happening a lot it has 180,000 on it

My tahoe caught fire inside the driver side dash. it was parked, no one had driven it that day. i put in a claim with gm (claim #sr 8-2955875514) and it was denied as they said there are no recalls for my tahoe. this fire started out of no where. thank goodness our neighbor came banging at the door to let us know that our tahoe was on fire. we weren't home at the time but my son was, we arrived to find him with the water hose extinguishing the flames that were coming from inside the vehicle. i sent the pics to gm and they just denied it with no other explanation other than there was no current recall. they didn't even tell me why the fire started no one came out to see the vehicle.

While driving on the interstate at 70 mph the car switched to reduced engine power and reduced speed immediately to 25 mph, leaving me in the position to navigate through rush hour traffic to get to the side of the road. after happening a couple of times over a 30 period, it is now a regular occurrence. each attempt to take the car in to a mechanic to be repaired results in the same issue occurring afterwards. mechanics seem not to be able to determine the cause resulting in a completely unsafe car. the throttle body has been replaced, wire harness, pedal sensor, and throttle body sensor. nothing has solved the problem!

Tl* the contact owns a 2003 chevrolet tahoe. while approaching a stop, the vehicle began to vibrate severely and the check engine warning light illuminated. in addition, the vehicle failed to accelerate when the accelerator pedal was depressed. the failure recurred intermittently. the vehicle was taken to an independent mechanic where it was diagnosed that the throttle position sensor failed and needed to be replaced. the vehicle was repaired, but the failure recurred. the vehicle was also taken to the dealer where it was diagnosed that the wiring harness failed and needed to be repaired. the vehicle was not repaired. the manufacturer was not notified of the failures. the approximate failure mileage was 166,000.

Speedometer quit working. gm needs to step up and fix this problem. *tr

When i when to pull out of my drive way 3 or 4 weeks ago i turned on my left turn signal and the four hazards started flashing! it stopped and started back up again and now does it all the time! *tr

Yesterday was driving home from work and came to a round about, slowed down and vehicle died (alternator gauge went below 14, oil pressure dropped below 40, and battery light came on). i lost all steering and brake pedal was stiff. now vehicle continuously idles rough and will stall out if not on the throttle, idles 500 and lower. i have replaced mass air flow sensor, air filter, plugs, wires, o2 sensors, fuel filter, evap canister, alternator, and had throttle body cleaned. see there are many complaints filed of the same issues and wondering if anyone at gm has found a solution. also have noticed gm has recalled the intake gasket but i have not received anything on this recall. *tr

Abs, brake service light comes, door locks cycle repeatedly, loses power and won't start. *tr

Not sure what is happening to my car but it is very scary when it happens. shortly after i start my car and it is warmed up, when i am driving it and i put the brakes on to slow down on a corner or at a intersection, my car will shut off. i can't steer and the brakes are hard to push. please help, don't want to kill myself or my family. *tr

My instrument cluster went bad while driving. i took it to chevrolet and was told there was a recall on the part but only up to 7years or 70, 000 miles. from what i know, gm was well aware that they made defective instrument cluster and don't want to replace them. i have 6 children to transport back and forth from school and practice, my speedometer not working is unsafe for my children. *tr

Tl* the contact owns a 2003 chevrolet tahoe. the contact stated that smoke came from under the hood. the contact took the vehicle to the dealer where it was determined that the blower relay resister module failed. this failure caused the air conditioner to fail and it smelled like plastic was burning. the vehicle had not been repaired. the failure and current mileages were 135,000. *tr

When driving, i noticed my speedometer registered around 80 and it was on a road that i normally go about 55. many others were passing me, and i couldn't believe people would be going 90 or 100. and i certainly didn't feel i was going 80. i slowed down to 55, and i was crawling. i came to a stop light, and my speedometer went down to 15 at a stand still. i sped up again, and the same thing. now it is stuck at 40 when sitting still and goes to about 100 when i drive. apparently googling this, it appears to be a massive problem and no one can understand why a recall hasn't been issued. the dealer told me a bad cluster at $650 to repair. this needs to be escalated and chevrolet needs to cover this problem. it is an extreme hazard on the road, and probably has caused many accidents and fatalities because of faulty readings. please let me know what else i can do to get resolution. *tr
