O2 Sensor Problems of GMC Yukon

Just got this vehicle 2 months ago. Brake lights seem to work when the want to. Have read others reviews and seems everyone with this vehicle is having the same issue! the cruise control works when it wants too,. Check engine light is off and on had it checked once while on and was told it's an O2 sensor. When the check engine light is on remote start won't work. Seems the brake light issue is purposeful since so many people have the same issue and it costs so dang much to fix it! for such a nice vehicle and expensive payment you would think there would be no issues.

The contact owns a 2003 GMC Yukon xl 1500. The contact mentioned that the previous owner of the vehicle experienced a failure with the reduced engine power warning indicator. The dealer replaced the throttle body, but the failure continued before the contact owned the vehicle. The contact experienced the warning light randomly flashing, which drastically reduced the speed to less than 20 mph. The contact had to constantly turn off and restart the vehicle, but the failure continued to progress randomly. The dealer replaced the wiring, 02 sensor, the throttle body was replaced a second time, the battery, and the alternator. The repairs failed to provide a permanent solution and the warning light continued to illuminate for the reduced engine power. The vehicle was not repaired. The manufacturer was not notified. The approximate failure mileage was 188,000.

I was driving north on 85 at 70 miles an hour and my vehicle decided to drop down to 20. I have looked up information on issues this truck has had and 1 of them is registered under NHTSA id # 100032435 / pip-4695. Loss of power hesitates on acceleration. 4. 3, 4. 8, 5. 3, 5. 7 and 6. 0 engines coupled with the 4l60e or 4l65e may experience a condition of hesitates, misses or loss of power under acceleration. The vehicle may operate as if it is in reduced power mode. I have purchased an air mass flow sensor, throttle body sensor, all 4 O2 sensors, and a coolant sensor. My truck is still not running at full capacity. I need some information on this and some help fixing my vehicle.
