In my RST Z71, I've lost traction because of the violent judders in the back which sent my truck into a tailspin and I nearly hit a pedestrian. I don't drive it much anymore, it was going to be a truck for the ranch but now it sits there nine months a year. I will never drive it again.

 

I watched the video a few post up and have a hard time understanding how anyone could believe this is not dangerous. Wheels off the ground, yes on both ends of the truck, prevent steering, braking and accelerating. Did we note the 28 mph speed the test section was taken on?

 

First week I had my truck I had something quite like your experience happen. Paved road, Wisconsin 140  northbound near I-43 on the north side of Clinton. Doing a bit more than 28 mph as the speed limit there is 45. Truck moved an entire lane to the right before the hippity hop stopped. It didn't even look that rough. Since repaired. 

 

This lead to a total suspension 'remake'. Custom springs and shocks. Don't park it. FIX IT.

Either way, this video shows in an extreme (notice none of these trucks step out to spin out and almost hit a pedestrian) how live axles and leaf springs made to carry weight act in regards to bumps... I think trucks these days have gotten a little worse as they have much stiffer frames/body's and the suspension is designed to carry more weight to the suspension is stiffer in most regards.

 

Then you need to watch the video again. Narrator even points out the 'step out'.  No, no one spun out. But then were were not driving where Wiggums was. If the road is there and the speed is legal then the vehicle should behave. Evidently his did not. Neither did mine. You can't 'cancel' and experience. :wtf:

 

And there it is. Everyone is trying to be King of the Hill and we have half ton trucks with one ton capacity. You can't buy less. (No, Ridgeline is NOT a truck. It's an abomination.) So you have to make less. If you need all that then you get to live with all that. But calling a guy out on a near miss then providing the information that proves his case is a bit bewildering. Serious. I don't understand.

Likewise, I was going 30 on a 35-mph road, foot off the gas due to the caked dirt on the road from the recent floods. I never expected the whole back end to fishtail, causing my truck to immediately veer off-course. I was really pissed when this happened, this has never happened in any of the other 4x4's I've driven. What made it much more dangerous was the front end seemed to do a good job of staying planted but the backend fishtailed wildly, within five seconds, it was already over 30 degrees off-course. Had all been even, I might have slowed down, but this.. is unacceptable.

 

The first thing I did was turn the steering wheel to the LEFT as fast as possible and SMASH my brakes to not hit the guy walking on the sidewalk. Despite the 30-mph, the fishtailing took approximately five seconds, yes ,it was that quick! If I was driving in my lane  instead of the middle of the road, I would have mowed down the poor guy. I have never had to do that in ANY of the cars or trucks (and I've driven a lot more than the average Joe). NONE of the cars should FISHTAIL, period. I get it when all get bouncy and the driver has to let off the gas.. but this? If anybody thinks that's acceptable is an idiot.

 

I could not understand why others ridiculed me over it, then I realized none of them have RST with the twin-tube shocks. The sheer ignorance.. fortunately, there's the ignore button. It has only happened twice and I now know to avoid such roads like that. Still, that pissed me off!

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.

      Gas Prices

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
