Hello everyone. My first time here. I have a 2021 Sierra AT4 with the 6.2L. I have started to notice a noise when towing our boat that weighs about 6,000lbs. Several times during the trip to and from the lake I hear a rumbling sound that last like 2-4 sec. almost sounds like it can be a jake brake or hitting rumble strips on road. I hit no strips. I can’t recall if it happens on downshift or what. But it does concern me. I drove home from work today with our towing and put it in tow haul mode. It made the noise 3 times in 45 min drive. Any ideas what I’m dealing with? Would it be a bad clutch issue or is this normal? I do have the performance GM installed exhaust and performance GM installed air intake. I called dealer today and they said bring it by and they MIGHT have time to get to it next week. I planned to hit the lake this weekend for Labor Day. Thanks.
2020 Rocky Ridge K2 Silverado 5.3L
First time posting.
Have been expereincing intermittent brake lights staying on after engine shut down for several weeks. Took it to the dealership, who ran a diagnostic on the truck and came back with "all things look normal, no codes". By the time I got home, the brake lights were in a state of constant "on" and I was able to restart the truck without applying the brake, even with the key fob outside the vehicle. Received several Onstar warnings to "Service Parking Brake". The parking brake had engaged and would not release. I disconnected the battery for 20 minutes, reconnected the battery which cleared the code. Called the dealership and was told I would have to leave it with them for awhile (several days to a week) to find out what the issue is. Would be ok except they do not provide a loaner car and rentals are thru the roof in our area ($100/day) so I have been living with this inconvenience until I can find an alternative way to work (80 miles rt).
Then this happened over the past weekend:
While driving back from the lake with my boat in tow, the truck went into a critical brake failure mode. Here is the series of events. Moored boat at dock and went to retrieve truck to remove boat from water. Could not unlock door on truck with FOB. Truck was "dead". No voltage activity. Used 12v portable jump pack to start vehicle. Let run for @20 min before proceeding to drive home with boat attached. Check engine light was on for 30 seconds then went out, but no warning dialog boxes. After we were on the road for @15 min, in rapid succession, I received the following warning dialog boxes: Service Trailer Brake System Service ESC Service Parking Brake Brake System Failure - 62 MPH Top Speed Check engine warning light Traction Control Off warning light ABS Off warning light As soon as I saw this, I tried to apply the brakes and they went to the floor. As you might imagine, it was chaotic in the vehicle when it became apparent that the vehicle along with the 6000lbs of Boat/trailer in tow was not going to stop in any timely fashion. Along with the trailer brake failure and vehicle brake reduction, the backup surge brakes on the trailer would not engage due to the lack of quick inertia braking force. I had the pedal to the ground and eventually we came to a stop. The rest of the ride home (2 miles) was a 5mph white knuckle event. The insult to the injury is there has been no warnings, email, text or posted on account from Onstar about this series of events but... I did get one on the same day that my Oil change is due. I am posting the screen shots I took after we came to a stop.
It is being towed to the dealership tomorrow. I will let you know what happens. I absolutely love my truck. It is the 5th Chevy that Ive owned, and sadly the worst one of the bunch. M
I am currently in the market for a camper and I am wondering how much weight I can tow. I have 2019 Silverado 1500 RST 5.3 V8 crew cab short bed. From what I can find online I should be “okay”, but really wanted some feedback from those of you that have a similar setup. I am aware the 2500 is the ideal setup, but that will be down the line a bit for me.
Truck Trailering Info:
GAWR RR 3800lbs
Max Payload 1819lbs
Max Tongue Weight 960lbs
Curb Weight 5281lbs
The camper I am looking at has a dry weight of 6300lbs and GVWR of 9,480lbs (no intent to load our camper down or travel with full tanks). Hitch weight of the camper is 680lbs. 32’ 11” tongue to bumper. Really only looking at going camping within 100 miles on the weekends.
We typically travel light with basic necessities for hook up campgrounds (clothes, food, chairs).
any help would be great!
Hello! I'm a new member looking for some opinions on towing. I have an 88 Chevrolet r20 suburban (3/4 ton). It's a 454/th400 combo. Not 💯 sure on the rear gear as the speedo reads about 10 mph off at 60 so some previous owner has tampered with the rear gear I'm sure considering it use to haul a travel trailer back in the day for a gentleman in the air force. Assuming I replace the 33 year old leaf springs, brakes are in good working order, etc etc do you think it would tow a 8k travel trailer safely at say 60-65 mph with trailer brakes. I plan to install a Firestone airbag leveling system on the rear as well. The factory hitch says it's rated for 10000 GVWR with a weight distribution hitch. I don't see a GCWR anywhere. Trailer specs are 36ft, Dry weight of 7756lbs, with a hitch weight of 942lbs.
