For those with radiator issues, would there ever be a warning light or other indicator? My truck's engine temp has always ran a little high when running at high revs for an extended period of time (like uphill highway driving, it sustains about 3K or so).

 

If you smell coolant or see steam rising from the radiator while in the car, your radiator is cracked/leaking. I had my mechanic do a pressure test on the radiator and that was how I found out it was leaking.

I really like the Toyota Tundra, but the gas mileage is the worst out of all the trucks. Toyota leads in car gas milage, so I just don't understand why they can't manage it better for their trucks when other truck manufactures can. If the Tundra can eventually get what my Silverado gets in gas mileage, then I will trade in a heartbeat.

 

This was the #1 reason I chose the GM over the Tundra and was my biggest mistake.

 

I live in Northern VA and most of my driving is around town. In the 3 years I've owned the truck, I've averaged 15 mpg. However, when I go on longer trips on the hwy I get 17-20 mpg which is awesome but only happens a few times a year. The stated mpg are lies for the most part. The mpg numbers listed on the window stickers are designed to "sell" cars, not to be honest and fair with consumers.

 

When towing I get 8-10 mpg around town and 10-13 hwy pulling my Suretrak 82" x 12' dump trailer with 2000lbs in it.

 

If I can only 14 mpg with the Toyota 5.7 motor, that would be an even trade especially if I could dependably run this truck 300k+ miles with proper care and maintenance. I'd gladly pay the extra fuel cost per year just to have a dependable car.

 

I loved this truck with a passion, I've had some awesome experience in it camping with my son and friends at the lake and going on my extended rock climbing trips. The fact that I can throw a queen size foam topper in the bed and sleep in it is AWESOME. I'll miss the comfort and bed space, but I'm going to take the loss now before all the value in this truck is gone.

 

This forum has been a wealth of information and great people. Thank you to everyone for everything.

Is this a silverado/Sierra forum or tundra forum?? You people should go join a Toyota forum.

I've got 29,400 miles on my 2015 CC Z71 5.3, 3.42.

 

I had an oil leak issue from 10,000-18,000 miles, but since that was figured out, I've had no issues. I really enjoy driving this truck.

 

I've got a lifetime mpg of 18.2 (according to the AFM)

Just over 42k on my 14 LTZ,

 

only issue ive had so far is a leak into my cabin filter that would freeze it up after the car wash in the middle of winter. still not sure it was that since its done it after that too.

Dude, I regularly get 24-25MPG...sometimes I have hit 30! In town, I am averaging 20. That is awesome! No way in hell a Tundra can do that.

Thanks for the reply, especially the last paragraph. You just eased my mind on getting the Land Cruiser or Lexus variant. To be fair all vehicles have their issues, but this one has started to spiral out of control for me. Every month for the past 6 months, something has gone wrong and I swear that this transmission isn't going to last much longer.

 

This truck is like a gold digging woman. It looks so damn pretty but it will also do everything to empty your wallet. All I want is reliability and I guess I have to go to Toyota for that. It should've dawned on me sooner being that my mom has a 2004 Sequoia with 350k miles on it....

That sucks you're having to put up with that. My girlfriend says the same thing about my truck. "Damn it's sexy, but holy shit does it suck." Don't get me wrong GM does make

some great stuff. The LS series of engines are legendary in their own right. GM has really mastered the small-block V8. I just expect more for my money that's all.

 

In comparison I feel the Tundra is more analog. It doesn't have a lot of bells and whistles. The design is definitely dated, but I guess that's why I find it appealing. Just a basic truck. Less to go wrong. I wish you the best of luck with your future vehicle and thanks for the response.

I got my '17 Oct '16, hit 10,900mi today love love this truck.

 

You couldn't give me a Toyota POS

 

Just returned from a trip towing our 9000# camper, worst day mpg was 11.1, best was 13.5. That Toyota probably wouldn't have made the mountains in WV pulling the load at 9mpg at best.......

PEOPLE: This post is about how many miles are on your 2014, NOT about your mpg.

Posted

2014 LTZ 5.3....I have 139,000 on mine. brought it last year 6/2016, had 111,000 on it, second owner. No fluids changed except for regular oil changes.

 

Had the common AC issues, last year was the cracked line that needed the bracket. now just discovered the condenser needs to be replaced due to the crack that every owner seems to have. what makes matters worse, its on national...NATIONAL, back order. GM should be fixing this for free!!!!

 

I have the driver assist system issue which i think has something to do with the vibrating seat. Mine only vibrates on one side and sometimes not at all.

 

I noticed a few months ago my water pump was squealing so thats the bearing. Not sure if I should/can replace them or just do the whole thing?

 

I've changed the oil cooling lines due to leaks at the crimps, trans lines are next.

 

Other than that...all good.

 

Before the 2014 I had a 99 rado extended cab with about 296,000 on it...only problems I had with that was a water pump that I changed once. alternator, changed twice probably because it was a cheap auto zone part, and a fuel pump that i changed twice sure thats due to purchasing it from eBay for about $55.

 

RUST...the frame had significant rust issues...noticed when I dropped the tank that one of the cross members was damn near gone due to rust...thats when I knew I had to part with my lady :-(.

 

It was little things due to wear and tear which is to be expected but other than that I had no issues. If it wasn't for the fear of my frame falling apart I would still be rolling.

    • I’m definitely interested to hear the end result here. 
    • 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.
    • 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. 
    • 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.
