ELECTRICAL SYSTEM: INTEGRATED TRAILER BRAKE CONTROL
4 weeks ago, constant repeated loud chime and visual warning stating " service trailer brake system". This is constantly alarming and unable to be cancelled or acknowledged throughout the drive. This results in distracted driving. Furthermore, it occurs both when towing a trailer or not towing. I have noticed decreased braking of the trailer as well. Have not gone to dealer yet.

SERVICE BRAKES
The Truck has something wrong with the Trailer braking system. with no notice it display "Service Trailer Braking system" in the DIC. This will cause loss of brakes to the trailer and make it very difficult to stop with the trailer. Everything functions properly and at a random moment they will just stop working.

POWER TRAIN
At 101,000 miles I experienced my check engine light and Stabilitrak dash lights coming on and the engine spuddering. I replaced the fuel injectors, spark plugs, spark plug wires, coil packs. I’ve taken it to two mechanics one told me that number eight cylinder was low on compression and the other mechanic told me that he has seen very many of the same motor that I have, with the problems associated with the lifter recall. I don’t know what to do. I’ve heard that the fix is the same part so it’s just going happen again. This is horrible, from a consumer standpoint Especially since GM has known about this since 2007 with their AFM/DFM motors. I would love to hear back from you pertaining to what my options would be for repair and payment. Thank you for your time and have a good day.

FUEL/PROPULSION SYSTEM
While driving to work with my workers and I on HWY going 70 mph pickup just turned off on me and no longer started up. Took to Mechanic and said it was the Bosch CP4 failure. Metal debris flooded our entire high-pressure fuel system. Had to get replacement of fuel lines, fuel rails, pump and injectors and the removal/flushing of the fuel tank. Our total repair is over $12,000. which we don't have. Mechanic just finished repairing it after 11 month's but we don't have the $ to get it out from shop.

ENGINE
The issues started when I began to notice that I was not having a constant flow of heat coming out of the vents inside of the vehicle. I brought the vehicle over to a local service center and the mechanic there discovered that my antifreeze reservoir was completely empty, but I did not have a leak. After filling the truck back up with coolant, a few days later, while driving, suddenly the truck began to run rough as if the vehicle went into "limp mode". I noticed that the check engine light was flashing and the traction control light was on. At stops, the truck would rough idle, shake, and there was a large amount of smoke coming from the tailpipe. I was able to get the truck back to the same service center that ran some diagnostic tests. He told me that there is a fault in the number 7 cylinder which has no compression in it. I had the truck towed to a local GMC dealership who confirmed that there was no compression in the number 7 cylinder and said that there was a lifter issue in the engine requiring an expensive fix. GMC had the truck from the Friday after Thanksgiving (the Year 2021) to January 4, 2022, to make the repairs. Repairs were delayed due to the dealership not being able to get the necessary parts in a timely manner.

STEERING, ENGINE
1. Truck is equipped with AFM (auto fuel management) I found out thru some research models since 2014 having collapsed lifters because of this feature. GMC has not made any attempt to recall this problem and let customers face the repair like me at the cost in my case of 7K. This truck has only 58879 miles on it. Not surprising models as new as 2021 had the same issue with no action taken to correct. 2.My truck lost the steering assistant feature putting me in a potential accident while i was driving. Steering the truck is difficult, especially at low speed which I decided not to drive it. I'm 87 years old and I'm facing numerous repairs for a vehicle with only 58K miles on it in order to safety drive my vehicle

Vehicle has a cp4 fuel pump. This pump has a high failure rate. Upon failure the vehicle shuts down and cannot be restarted. This can happen at any time and anywhere. Can happen while on a highway or freeway. This vehicle is used to haul heave loads. This failure can ending up to $10,000 or more to repair. This failure has not happened on this vehicle yet. Am very concerned about me safety and the safety of others because of the high failure rate.

I started the truck and did not have power steering. If this would have happened while driving it could have been very dangerous. Why is this not a factory recall?

2015 gmc sierra crew 4x4 with 92k miles suffered from lifter and push rod malfunction on cylinder 7. The engine started making a knocking noise, there was a loss of power and the truck was shaking. It seems this a common theme with these trucks.

SERVICE BRAKES
Purchased GMC Sierra C1500 new in 2015 from a dealership in Orange County, CA. Experienced multiple issues over the past 4 years with the "Trailer Brake System" Service light and loud beeping which has created multiple safety issues making the vehicle undrivable at times. The last incident was while on a cross country road trip through extreme heat in the Southwest from Texas to California in June and most recently while visiting Orange County. The beeping noise almost caused a couple of accidents as the hands free phone system was inoperable due to the loud warning beeping noise as it went on and off about 50 times. We were required to take several risky maneuvers to pull the vehicle off heavy highway traffic at high speeds to stop the engine and restart in an attempt to reset the warning beeping system without success. The truck was checked in for service on 07.20.2022 at Tustin Buick GMC. Mr. John Boozer, Service Advisor. 714.669.3699. The total cost of repairs is $465 plus car rental of $80. Additional costs in April of 2019 for the repairs included fuse replacement, check of wiring harness and attempt to stop the beeping noise was $150. The defective wiring harness originally installed by GMC when the truck was built will be preserved and is available should your agency request it. Total costs out of pocket to replace or fix this factory defective part is $695. GMC has made no effort to address this issue or offer any recall notices related the failure of the "Trailer Brake Warning System". Thank you for your attention to this matter.

SERVICE BRAKES
On July 18, 2022 my trailer brakes suddenly stopped functioning ( a few hours from home) Not only did did the trailer brakes stop functioning, but this warning message didn't popped up just one time, it kept coming again and again and again and again, relentlessy chiming and distracting me from driving. it covered my speedometer readout. it prevented me from receiving or making voice commands. the service warning chime also prevented the turn signal from functioning. So for a full 4 hours I was constantly reminded and was unable to receive calls or make voice commands. i absolutely wont hesitate to say the vehicle was not safe to drive in that condition. your vehicle's defect endangered my life. I will not hesitate to say your vehicle was not safe to drive in that condition. Your vehicles defect endangered my life! Lastly, my vehicle did not want to start the next morning!!

ENGINE, ELECTRICAL SYSTEM
When decelerating and turning left the car goes completely dead. First time I just about got killed on the highway. The other two times I knew to put it in neutral & crank the car. No steering no nothing. Days Chevrolet in Jasper, Gais trying to tell me there is NO RECALL on my serial number. I see there were a lot of them years ago. In addition to that my power steering occasionally goes out. The last time I was backing into my garage when I had to manually turn it. Hard to do for a woman.
