2002 Chevrolet Suburban: sudden loss of power

Filed Apr 27, 2011 · Engine · 174,000 miles · UT

While driving vehicle losses power, reduced engine power light comes on. I have taken the suburban to the mechanic. Change the maf, tps, air filters other sensors that the diagnostic test has pointed out as problems and have had a vehicle tune up done (new spark plugs, wires, oil changed, etc.) the cost of these repairs has been over $1000 and seem I will be spending more. The problem continues to happen. Reduced engine power while driving. I am afraid this could cause an accident and cause injuries or even death since it happens while driving.

My wife and I have been very happy with the vehicle until a situation last year. Specifically, there is a known problem with the gas tank and gauge. The gas tank will be a 1/4 full but the car will not start because it thinks the gas tank is empty. My local gm dealer service center quoted me over $800 to fix this problem. It is a known gm defect. Gm's technical solution is document id # 1575648. It reads: vehicle with flexible fule (rpo l59) will not start, stalls and will not restart, loss of power, poor performance, and /or fuel guage reads inaccurate/incorrect (replace fuel sender/module assembly) #04-06-04-012b - (dec 6, 2004) * replace fuel sender /module assembly with redesigned fuel strainer and /or redsigned fuel level senor can you please help ? Thanks, brendan and lisa o'reilly.

Purchased a new 2002 suburban k2500 in aug of 2002. At 17,000 miles, the air conditioning went out. Dealer replaced the compressor. At 27,000 miles, the fuel gauge showed empty when the tank was full. Dealer replaced rear fuel tank sending unit. At 55,000 miles, the fuel tank again showed empty with a full tank and the engine surged. The dealer (bob steele in cocoa fl) replaced the fuel pump in the rear tank and the sending unit in the front tank under my extended warranty with a deductible. Dealer stated this was not a recurrence of the problem before. At 58,000 miles the car stalled while crossing over a busy bridge/causway at approx. 60 MPH. "reduced engine power" glared on the warning indicator, power steering was lost and lights on the dash were flashing erratically. Luckily, I had crested the top of the causway and managed to steer to the tiny shoulder without crashing into anybody. The car would not start immediately, but after trying for fifteen minutes I was able to get it started and drive home. I called the dealer (it was five minutes to closing time) and was told to bring it in the next day. It stalled again at a traffic light on the way to the dealer but started immediately. The dealer replaced the throttle position sensor under my extended warranty with deductible and again stated that none of these fuel/stalling problems were related. The car stalled again recently and the dealer said to bring it in if it happens again. This is starting to become a very dangerous situation that the dealer seems to be very unconcerned about.

Driving at highway speeds, car engine died immediately after sputtering and losing power. First time this happened, I pulled off the road and restarted the car almost immediately. Drove another 600 miles without incident. Second time, car died again at highway speeds. Restarted after 15 minutes. After reporting the problem to on-star and having remote diagnostics run, I drove another 25 miles towards dealership rather than waiting for tow. (118 deg heat in desert sun). Engine failed again about 200 yds from dealership. Dealer replaced fuel pump, pressure regulator, and filter. Cropper auto group in casa grande, az, kept the defective parts. I have had problems before with fuel level sensor indicating properly on this vehicle. This repair also replaced fuel level sending unit. $800+ repair. 60,000 miles on the car. Extremely hazardous loss of power and control when engine dies without warning at highway speeds. Noticed at least 5 identical complaints on the federal safety agency website: oid id numbers 10041486, 10079660, 10099685, 10100051, 10126511.
