Despite replacing Throttle Body and Accelerator Pedal Position Sensor, I continue to have my Suburban go into Reduced Engine Power without much warning. It is very dangerous when you are driving on the freeway and your vehicle suddenly will not do over 35mph with the engine revving to 4000+ RPM. I've spent nearly $1000 at repair shops and have found that nothing they attempt will fix the problem. I cannot trust vehicle with my wife and kids riding any distance in it.

The electrical system has gone out completely comes back a few seconds later with different icons saying to roll driver side window down then up, or stabiltrax. It has also caused complete electrical failure being on a road while driving. This has also cause my wheel to jerk taking out the power steering and the engine has shut off completely to the point where I have to wait a few minutes to even turn it on. This has happened while reversing in to a parking spot and the whole car dies. It kills power so much that I have no hazard lights. When I-€™m able to get it to come Back on it-€™s like it reset its self. I have taken it to the shop and they have said the battery cables and the mega fuse above the battery. I know this is a known issue in other like vehicles.

Persistent SERVICE TRAILER BRAKE SYSTEM warning indicator. Warning constantly sounds. Vehicle cannot be driven safely due to the sound and vehicle is unable to tow.

Vehicle dash and headlights turn off while driving, engine stalls and dies, power steering becomes inoperative. Transmission pops out of gear and freewheels. Service stabilitrack light. Very dangerous situation for my wife and 5 kids when this happens on curvy backroads at night like just happened last night! this is also the same problem as our previous Chevy Tahoe so we knew the problem was likely related to poor quality battery cables that are degrading prematurely. This should not be happening on a 3-4 year old vehicle. After searching a GM web forum and finding other people complaining about the same issue, there was a reference to GM tsb 18-na-161 on this exact issue I am absolutely amazed that GM has not done a recall on this yet, as it is a major safety failure likely to cause a crash and potentially a fatality. I checked the tightness on the connections by hand, which were both very tight, then I reseated and torqued the battery terminal connection. I measured the resistance across the power jumper, lug to lug. This is GM part number 84494554, and I measured 0.3 ohms across this little section of wire at multiple points on the lugs. Trimming back the insulation and continuing the measure, the highest resistance appears to be coming from the wire to the lug connection at the fuse bus, and not the crimp connection at the battery terminal, and not the bolted connection to the bus. There were some strands broken at this connection. I made and added a temporary jumper of the same wire gage, and the resistance across the same measured points dropped to 0.0 ohms. Absolutely a major safety issue if the vehicle suddenly dies without warning. I can see this same issue happening once, I forgave GM once years ago, but with the same issue happening to two different vehicles 8 model years apart, the safety of my family is too important to buy GM product in the future.

Vehicle was turning at a "T" intersection into oncoming traffic. When cranking on the steering wheel to turn left and accelerate, vehicle steering wheel jammed up. Thankfully, vehicle was able to keep driving & clear intersection before approaching cars arrived. Upon restarting vehicle memory systems in vehicle were erased and an error message flashed stating to roll down then back up driver side and passenger side windows. Later that evening when putting vehicle into reverse and sharply turning wheel to the left the vehicle lost all power and turned off completely while in reverse. Again, thankfully, I was in a drive-way with no other traffic around. When I re-started the vehicle the stereo memory erased and the roll down, then back up driver and passenger windows warning flashed again. This is all unsettling because I frequently drive in areas of heavy traffic and intersections that can be tricky to cross/turn into therefor requiring my vehicle to respond appropriately and not turn off while in gear.

This vehicle keeps having key fob, electrical issues, tire service maintenance issues, and now engine issues related to the key fob. The key fob keeps saying it is not detected. Recently, while driving on road at about 48 mph, key fob notification came on dashboard saying key fob was not detected, engine shut off and car had to be restarted again using fob box inside glove compartment, this was particularly alarming. The key fob has had batteries replaced and they work because the car will remote start and have tried batteries in other items. The fob does not however let you unlock the car or finish starting it out of the remote start once you get into the car and try to start it, the car tells you it cannot detect the remote. The car has had numerous key fob issues and has been taken into local Chevrolet dealer who cannot find issue. The car has also had 142 hard braking events since April 2019 to November 2019 according to on star reports. The tire service monitor keeps flashing that there are issues with tires. The rear wiper would not shut itself off even though button was in off position. All of these issues have not been able to be repaired at the Chevy dealer. This car is going back in for service 11/18/19 for these issues again. Not sure what the outcome will be until after this appointment. My guess is that it is some kind of electronic circuitry problem(s) but unfortunately the dealer says they cannot find any issue(s) or problem(s) until it completely shuts down. These events are ongoing and have been occurring intermittently since November 2018. All I can provide is photos of the dashboard showing what it relates to me unfortunately I have no documentation of engine shutting off only a photo of what dashboard showed when it happened.

We were in motion and the car suddenly died completely. We were later to learn that the body control module (BCM) had shorted out. We leased the car brand new and had only had it for three months when this occurred. Thankfully we were not in a busy road when it happened, otherwise we could have been killed. On top of this, the Chevrolet dealership to where the vehicle was towed told us that it was not covered under warranty and required us to pay to replace the BCM (initially they quoted around $700, but then after we complained, they said they'll "split it with us" and reduced it to around $350).
