I think those valves have been proven to do nothing at all, except cause whistle sounds at low speed and no starts when they freeze shut. I bolted mine open and drove it like that for several months before trading it and I never noticed any negative at all. My advice to anyone who hasn't yet is...bolt er open!

True, in my Silverado I "felt" Harley exhaust, and louder cars throuhg the floor and pedal. In my Ford, I can actually feel the wiper blades in my gas pedal and when stopped with the foot on the brake. Ford trucks do transmit road to the drivers foot, but I wouldn't call it a vibration. It seems to lesen quite a bit after 5 or 6 thousand miles too. Total different suspension and like they say..they ride like trucks. It took me a while to accept that after driving GM trucks for so long. But, I like the ride a Ford gives and it is much better than the 14 GM I had. In the Ford you just know you're driving a truck, in my 14 Silverado you knew you were driving something with some sort of problem. I keep checking back in here in hopes there's a posted fix and that it's behind everyone now but that doesn;t look to be the case. I do think that as trucks get lighter and lighter, we're all going to "feel" more regardless of brand. The Govt is forcing the manufacturer's hands with little time to vet out the design and it's impact on ride.

I dont think we can even start to compare what 2 or 3 guys think they "might" feel in their 2015 F-150 and what's going on with this enormous GM vibration issue. From what I understand, Ford's new F150 uses the same frame, drivetrain, and suspension as their 09 - 14 trucks which had been solid...they redesigned the body panels making them aluminum, completely redesigned the interior, and the front grill, and front and rear lights. There are reports of poor fitted body panels in the 15 F-150's but I'm betting they dont have a vibration issue on their hands like GM does still.

Agreeing with another forum member and also wishing everyone satisfaction in the end rubbed you the wrong way? I just popped in hoping to see people posting a viable fix for GM's vibration issue but ..nope. They're still selling 6000 lb vibrators with not a care on the world.

YUP! I dumped that vibrating 2014 Silverado and couldn't be happier. That truck was evil and was ruining my life with all it's problems. I hope everyoe is able to find satisfaction in the end.

I cant tell what you're saying there. I was saying not to blame the SRA tires, and you say you now have 20" SRA tires and your truck rides fine.

A lot of people are questioning the Goodyear SR-A tires, and I did too when I was forced to troubleshoot a vibrating 2014 silverado. I dumped that LEMON and now drive a 2014 Ford F150 XLT 5.0....I also have Good year SR-A tires on it and it rides very nice on the highway. They're not great tires for snow, but they do alright. Mine have the red dots on the sidewalls and they'll all in different positions on the rim from the valve stem. I wouldnlt blame the GY tires..they arent the source of your vibration (if they've been rebalanced once). Balancing a tire isn't rocket science..they come balanced from the factory, if you had them rebalanced and still get the vibs the 14 and now 15's are showing, you can eliminate tires completely. My SRA's ride pretty nice. I will swap em, but only after the tread is toast. So far I have over 7000 miles on them, they've been rotated once and still look like new. Those new GM trucks are evil, and I'm glad mine is gone! I actually look forward to taking it out and going for a ride. Do yourselves a favor...life is too short so dont let GM put you through this garbage. Get rid of it and get yourself another brand. I'm not here to push Ford...and never dreamed I'd be driving one, but wow they're really nice trucks. LOVE mine! Trade out and get on with your life. I was there too and am glad I got out. I feel bad for those whi just got into what many of us have already been through (compliments of GM). There are better days ahead! It's just a truck so trade ot when you're able and your life will be improved. Hang in there guys.

Glad yours was an easy fix. They tried that with mine but it didn't help a bit. The first 4 or so visits they were totally focused on tires...balancing, remounting, rebalancing, doing the voodoo tire dance. Nothing made it right. They did so much to those damn tires I figured if they did solve the vibes mine had I would have been afraid to rotate and or balance the darn things. That lemon is gone...my new F150 rides like a beauty and I routinely catch myself doing 75 to 80 on the highway by mistake. With that silverado I avoided 65 and up like the plaque. Not the way to live when driving a new truck.

If this wasn't a very large and widespread issue, why did the service writer at the dealership where I was taking my lemon 14 GM say "we have a ton of problem trucks out there...in fact not a single one on the lot doesn't have the vibration problem"? If it were just a tiny amount of trucks ....why do all the used lots for dealerships have a bunch of 14 GM for sale? Geesh the Ford dealer I go to now has 3 sitting out front. I've never seen so many people get out of their brand new truck for another brand...coincidence?? If it's so easily fixed with tires why did two GM engineers swap my tires, rims, drive shaft, shocks and still not fix the shakes mine had causing my to dump it?? If those 14's are so great why are the lots full of them? So full GM stalled releasing the 15's for two months! ....and now GM is offering people 0% and $9000 off if they go buy a 14 GM truck? If the 14's are so great...why did Consumer Reports drop the 14 GM truck from their Recommended vehicle list, listing quality and reliability problems? WAY too many people are in complete denial. GM turned a corner. They used to care about their customers and they build a quality product. Now they could give a &$%# less about customers, and they build the cheapest, piece if garbage on 4 wheels. I owned on for 8 miserable months and everything about it was cheap and flimsy....quality has taken a back seat as far as GM is concerned. Those 14's will not last on the road...mark my words. They're built to fall apart...and mine was falling apart in probably 10 different ways with only 11000 miles on it.

I hope it's gone for your sake...but mine came back after a tire change, and many other people's did too. I'd wait a bit until after you have a 1000 miles or so before considering it fixed. Surprised you had a vib issue with your Ford, havent heard of any Ford's with vob issues. They ride rougher than a Chevy but they dont vibrate. The online forums are pretty clean on this too. I researched it heavily before dumoing my 14 Silverado and switching to Ford. Now I look ofrward to driving my truck again.

I've said this before but...trade out of your lemon and get into something else. Your time and worry isn't worth it and GM isn't exactly jumping to fix this issue. It's a disgrace on GM that this design flaw was allowed to carry over into the 15's!I was alife longer Chevy owner and never pictured myself driving anything but, however I traded my 14 GM for a 14 Ford and am once again happy with what I'm driving. Trade out of you can. I'm not pushing any certain brand (as long as it isn't GM) but the 14 Ford F150 is probably the best built Ford that they've ever built and there are still left overs that you can find at amazing deals as the 15's just starting showing on lots. I'm very happy with my Ford XLT.....GM and their crappy product ruined an entire summer for me, and cost me a lot of personal time running back and forth to the dealer. Get out while you can...I gave them 8 months to fix mine, and special engineers from GM couldn't make it better.

Personally, I'm shocked that the media hasnt covered this quite a while ago. Many of us have een burnt...far too many, I did. There's soe that say we're such a small minority. I call bull on that. Early on at my dealer I was working with....out of a see of silverados we couldnlt find ONE...not a single one that didnt vibrate as bad or much worse than my lemon. Honestly, I think the guys who are like "my 14 is great"...I say wait your turn...it'll get you and soon. I wont list all that was wrong with my lemon 14 (alreayd listed it here) but it had a rediculous amount of thngs broken and more started weekly. I was at the point that even if they fixed the vibs I had, there was far too many other things wrong with it that it wasn't stayng in my drive way (things that others have mentioned here and all the other forums). I've bought a lot of trucks, and have never seen a forum of any model year or brand so filled with systemic problems. How did al this not get worked out furing GM's "million miles of testing". Getting back to media coverage.....how do they not pounce on this issue? GM takes tax payer money as a "means to stimulate the US economy"...and then invests in manufacturing in Mexico and Canada??? How was that even allowed?? Then they design sub-par trucks where corners were cut in every way possible and then sold to US consumers and we're made to suffer with GM's lemons. I mean....how is this not getting full coverage on the big news channels? Meanwhile, my new Ford I traded the lemon 14 GM for...6600 miles so far, no recalls, no returns to shop except for my free oil change and tire rotate....it's just a better product all around. And for those who say we're such a small number...no dealerships around here are taking trades on 14 GMs....they have a bunch out front at each and cant sell them. I lucked out and thank God I traded mine when I did or I'd be stuck taking an enormous loss to get out of it. GMs insulting offer minus money because they made me rack up 11000 miles while they screwed around and couldn't fix anything on my lemon made it clear they could have cared less about me, a former life long GM customer who will now never buy or recommend another GM product for the rest of my life. I hope you do have Fox news interested in doing a story...this needs to get out there past all the message boards on the Internet. If you have a link to share regarding what you have in the media please post it here.

Yeah, mine had 12,000 miles and some change when I traded it in. It seemed to get worse from when it first started vibrating at 1000 miles to when I traded it. I do remember a mechanic telling me it'll be a different truck after 10,000 miles and an alignment but that didn't hold true for me. Glad it's gone!! I think all trucks need to be aligned after the suspension settles, things wear in, etc. Ford is giving me an alignment and wheel balance at 15000 miles once I'm there.

I should point out that...when I had my 14 GM I was convinced it was tires, but didn't want to invest in new ones "just in case" it didn't fix things. My new F150 has the same tires (GY SRA) and they actually ride pretty nice. I took the family on a nice drive yesterday, 208 miles mostly highway and the truck rode great...very comfortable. And, it was in the teens all day and I averaged 19.4 mpg the whole trip. Love my F150 with it's 5.0!

I went through 5 repair attempts with the last two visits done by GM engineers. I figured...now we're getting somewhere when the Engineer was called in. He swapped tires like a minimum wage tire monkey would, and that obviously had no effect at all. After all the time and money they spent trying to figure out my vibration issue, spanning 8 months and 11,000 miles with no improvement....my truck was suddenly deemed "performing as designed" and the case was closed. If they had been honest and advertised that they designed a vibrating peice of sub quality garbage on 4 wheels that would have been one thing...but thats not what they advertised. MY new truck got more money in parts and repairs than all other vehicles I've had over my life combined! There is NO FIX for this vibration....but GM will keep making them the same way, with the same defective design...and will keep selling them to you and taking your money. GM has stopped caring about the customer, and about their reputation. GM's primary goal is taking your money and putting it in their pocket. I truely believe we're witnessing the slow death of GM. They're bleeding money with all these recalls, and cannot legally accept another bailout on the taxpayers dime. They've dug themselves a deep grave by putting profits ahead of quality and customer satisfaction...and thats the absolute shortest lived business model you can implement. After owning one of those vibratorados for 8 months, talking with mechanics and service managers at two dealerships, and several same truck owners in my area it's very clear that those trucks will not, can not last a long life. I personally think someone would have to be crazy to keep one past the 36,000 mile warranty period. I had everything breaking on mine before 11,000 miles and this forum is FULL of people experiencing those same breaking parts. The fan boys will attack me for sayig it...but I say it based on personal experience with that same model truck so... I would make them have a 3rd try, and then open a BBB claim and get a lawyer to put pressure on them so they buy the truck back and go with something else. I'm not pushing any certain brand...I'm just here to remind people that you dont have to suffer at the hands of GM. You dont deserve it, and you have options to end the nitemare and get into a vehicle that drives nice and that you can be happy with. OK, I've go my flak jacket on now...go for it GM fan boys! HAHA.
