2015 CHEVROLET SILVERADO 2500 Complaints

In 2017 the truck started making a slight ticking sound from the engine so I asked the mechanic about it when I got the oil changed and he said it was a valve problem the GM had no fix for yet. Over time the ticking got louder so I took it back to the dealership last year and the noise as it turns out was from the exhaust manifold bolts breaking off and the exhaust is leaking into the cab. I contacted GM and could not get them to pay for the repairs. After doing an internet search I found out that this is an ongoing problem with these trucks. This is a safety issue and GM needs to fix the problem. Nhtsa made GM do a recall on the 2019 Buick Enclave because of a possible exhaust leak under the floor and I believe GM should be forced to do a recall on these trucks considering the exhaust fumes are coming out directly in front of the drivers compartment.

The fuel injection pump malfunctioned causing the truck to shut down going down the highway. It was taken to a professional and was confirmed to be an issue with these vehicles. There was no warnings at all. The cost to repair was $8000.00

Trailer brake system alert constantly comes on. with or without trailer connected. It comes on from the time I start the truck until I shut it off. It is a distraction when the warning chime is constantly ringing. I can't even use my speaker phone due to the chime constantly ringing. I took it to the local dealer and they can't find the problem. No code comes up on their machines for the problem. No other problems before this happened. Just started about 2 months ago and will not shut off.

I was driving on Interstate 15 northbound on March 6th, 2023. I was driving 70 mph, my truck dash had a message come on that said Stabilitrak needs service. Once this came on the truck dropped down to 45 mph during rush hour traffic. My truck is currently at Young Chevrolet in Layton, Utah because this happened again last week on Monday April 3rd, 2023. The Stabilitrak message came on and then my PRNDML indicator disappeared. I could not get the truck to go into any gear besides neutral and drive. I had to shut the truck off, wait then restart it. This happened when I was trying to back the truck up into my driveway and I was almost hit by another vehicle. The technician at Young chevrolet said my TRANSMISSION CONTROL MODULE WAS BAD, from my own research of online forums and social media pages, there are numerous others with the same exact problem. Others have gone months to almost a year without their trucks back on the road and GMC and Chevrolet do not have a replacement part, nor can they make any repairs to this module. Some have been told by the end of april they will have replacements, others have been told July-October of this year. This affects model trucks 2500HD and 3500HD years 2009-2015. This HAS TO BE A RECALL AND GMC/CHEVROLET/ACDELCO NEED TO REMEDY THIS PROBLEM ASAP.

CP4 failure, caused metal fragments to go throughout fuel system and tank. Entire fuel system had to be replaced and tank cleaned out. CP4 failed in the middle of my drive home, stalling the truck in the middle of an intersection. Luckily had enough momentum to roll and pull over to the side of the road.

Driving 70 on interstate 15 and the stabilitrak message came on the dash, truck went into limp mode, the truck went from 70 mph to 45 mph really fast. This was during rush hour traffic and I could have gotten in a wreck. This is a transmission control module and GM and Chevrolet DO NOT HAVE THE REPLACEMENT PART. It’s on a nationwide back order

Fuel pump failure while driving highway speed 70mph pulling a trailer. Engine light came on and engine went to limp mode for a few seconds then completely shut down without warning while still going at least 60. Lost power steering and power brakes. Service center confirmed the code for "low fuel rail pressure" and did the repair. I have retained the CP4 pump for analysis. I was very lucky to not crash my truck.

Truck went into limp mode. Stabilitrak check light came on vehicle slowed down to 27 miles per hour.

The contact owns a 2015 Chevrolet Silverado 2500. The contact stated that while driving at various speeds, the vehicle entered LIMP Mode with a warning message indicating how many miles before the vehicle would independently turn off. The contact had taken the vehicle to a dealer and was informed that the diesel exhaust fluid (DEF) tank needed to be replaced; however, the failure returned. Over time, the rear brakes, rotors, calipers, and various other parts had been replaced; however, the repairs failed to fix the vehicle. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 143,000.

CP4 pump failed sending metal through out fuel system. Pump, fuel system flushed, injectors all need replaced. Truck stalled in motion. Thankfully I was able to safely pull over without accident occuring.
