**randomly at any given speed ** First the radio system will randomly turn off then moments later-?? stabiliTrak off flashes followed by abs and traction control lights on dash then suddenly my Chevrolet Silverado has a mind of its own ! The door locks will flicker uncontrollably, and the vehicle just suddenly has a loss of power while rpms and gauges are continuously moving while you are unable to even move the vehicle.. this is a ongoing problem since 2019, that no one seems to have an answer too.. I-??ve taken it to 3 different mechanics and still no answers -?? when it first started happening it was super random and would happen a few times a day but then not happen for months on end then all of the sudden now it is happening several days a week.. I-??m currently scared to even drive it which is horrible considering the amount of money I-??ve put into this truck.. it has only 100k miles but somehow I am stuck using my dads old truck with 330k miles on it which seems to be more reliable and is 12 years older -?? sucks to pay over 500$ a month for -?? your dream vehicle -?? that you can-??t even drive or get any real answers to what or where the problem is coming from -?? seems that thousands of people online have the same problem but yet no one has any solution.. Now that I-??ve almost been in 3 serious accidents I decided I have to say something, 2 of these times were over 70 mph on a California freeway !!! Something must be done !

1 owner. Never driven on salted roads(South Louisiana).live 100 miles from coastline, not in a saltwater environment. Or driven in water other than rain. Cruise control dropping out, automatic transmission not shifting when supposed to. Traction control dropping out, service messages cycling in and out--traction control, stabilitrac, anti-lock brakes, check engine light, red brake light comes on and off. Speedometer going crazy. Brought vehicle to GM dealer for inspection/repair. Cause- internal failure of ecbm-electronic brake control module, due to corrosion in the connector due to water intrusion. Had to replace the module, and the vehicle chassis wiring harness. Total repair was $1,830.39 for parts and labor. The dealer reported to me that the design/installation location of this module is flawed, and a faulty design allowed moisture to get into the module thru the connector.which also resulted in the wiring harness connections into the ecbm also becoming corroded.. dealer also told me that this faulty design will eventually become a recall, and for me to keep my invoice of this repair, as to be able to claim a reimbursement for this repair.

I was making a turn while pushing on the gas pedal lightly, and all of sudden the gas pedal went to the floor without pressing on it and the pedal got stuck. The engine raced up to over 5000 RPM and about 60 mph around a turn because it would not slow down. I had too keep tapping on the gas pedal to release it. Also my foot was on the break.

One night on the way home from work, I was driving 60mph and all of the sudden my truck hydroplaned. I managed to get the truck straight and regain control of the vehicle. About a week later, as I'm heading home all of the sudden my ABS, brake, and traction control lights all illuminated. The dic reads service stabilitrak and service traction control, then it will display stabilitrak off and traction control off. I had the codes read and my trouble code was P069E - fuel pump control module requested mil illumination and U0073 - control module communication bus a off. All those lights mentioned above have been on for about a month. I looked up information about the fpcm and found out about GM recall 14515, I entered my VIN but the only recall that came up was for the takata airbag recall. As I read through the 14515 recall, I feel my truck is affected by it because, while driving the truck my speedometer jumps all around and is not stable. Also, when I try to accelerate, it feels like the engine stalls and there's no power there. Other times, it will down shift to increase rpms, but then soon shift gears into a higher gear then shift back into a low gear and repeat this until I let off the pedal. My tow haul mode will not stay engaged, cruise control will not stay engaged, and most of the time my truck won't even start when trying to use the remote start, instead lights just flash as I'm holding down the start button on the key fob. The truck feels really sluggish almost like there's no power, it seems like it hunts for the right gears while driving. Overall it just feels unsafe to drive.

Driving about 60 mph about 10 miles into the trip when the truck lost speed, the ABS brakes did a slight on and off pulsating every couple of seconds, the engine was running rough and giving it gas the engine revved up but wouldn't go anywhere. Speed dropped down to 35 or 40 mph and wouldn't go any faster. The dash indicator showed messages stating stabilitrak traction control turned off and check engine light is on. It jolted real hard when it shifts gears. When I mashed the brake it didn't want to come to a complete stop without pressing the brakes to hold the truck there. I pulled into a store popped the hood and finding nothing I turned the truck off for a few seconds and restarted it but nothing changed and the error messages were still being displayed. The trucks engine was running rough. I headed home and it didn't have any power and jolted hard as it shifted gears. I coudln't go but 35 or 40 mph on the level ground. If I went up a slight hill the truck slowed down more until I got past the hill. I gave it gas and the engine would rev up but had no power and wouldn't go 35 or 40 mph. I parked the truck in the garage and in 10 minutes I went to start it to get the error messages and it started up fine and the engine wasn't running rough. I drove it 1/2 mile down the road and back and it ran perfect. I googled the error messages and found alot of complaints and comments about this issue on the Chevrolet forum website. No recall information just alot of people experiencing the same issue and alot worse cases that almost caused accidents. Is there a recall on this issue? I read that I will probably have the issue again because after it sits for 10 min it probably won't have a problem until a few minutes or days later. I can only hope doesn't cause me to have a wreck and kill myself or someone else. This is a major issue and should be recalled to fix the problem.

Speed control (cruise) does not hold. While going down an incline from the mountains, cruise control was set for 65 mph, and the vehicle increased speed to 85+ mpg before applying brake to slow down. Called dealership and took vehicle to be checked in regards to this incident, and they stated that due to the department of transportation, new emission standards that transmission was made not to hold so as not to increase carbon footprint. This causes a very unsafe condition when driving when the cruise control is engaged.

This is a dealer demo vehicle, first 2235 miles were demo. During my first morning (12hours after picking up at dealer) of ownership I was descending down a hill with the cruise on, and the vehicle proceeded to over speed approximately 5-7mph. I travel this hill both ways to/from work daily and this happens everytime. I though this might be an abnormal adjustment within the computer/etc so while taking in to the dealer for a TPMS (tire pressure monitor system) issue I mentioned the overspeed issue to the service write up and they said that it was normal. I don't agree, but maybe it is. It does adjust back to normal cruise set speed but is unique. I had a 2002 Dodge Ram 1500 previously and it did not do this, and I have drove otr (over the road) semi-trucks and know the difference with overspeed being normal and abnormal. I would like this to be looked into, as it could be a hazard that could lead to unsafe situation.

#1. vehicle accelerates when letting off gas, even while going uphill the vehicle will accelerate. You can go up a steep hill without touching the gas. Brought the vehicle to the dealership they replaced, the throttle body, gas pedal assembly. They reinstalled the original parts and told us that this was normal. We drove other 2011 Chevy Silverado's which did not do the same thing. The dealership told us that all the 2011 Chevy Silverado's accelerate on their own. #2. there is a clunking noise from the rear when driving over bumps. The dealership said this is normal backlash, and did not do anything.

My 2011 Chevrolet Silverado 1500 has unwanted acceleration. Its been happening for apprx a month, on and off. On Tuesday 10/4/2011 I was leaving my parking space at work, I had my foot on the brake as I was turning out of the space, the vehicle just took off - accelerating without touching the gas. I then hit the brake which stopped the vehicle. I then got on the highway - (I-94) to head home, while driving on I-94 my vehicle lunged forward nearly striking the vehicle in front of me. I then backed off and kept a safe distance in the event that it happened again, sure enough - my vehicle started accelerating on its own. I realized it was doing it and had enough distance between me and the other vehicles ahead, so I allowed the vehicle to take off. My Silverado got up to about 1500 rpms at 60mph, I clearly had my foot off the brake and the gas, feet flat on the floor. I allowed it to accelerate on its own for apprx 1 minute but then had to stop. It is clearly driving itself. I drove the truck straight to the dealership and left it for the shop to look at the next day. The service dept could not re-create the problem, go figure. In the past month I've nearly hit several parked cars when pulling into parking spaces as the vehicle takes off accelerating, in these events I was also able to stop the vehicle w the brake.
