  1. Well I checked the terminals. Everything was snug, and they didn’t look dirty at all, but I got my terminal brush out and cleaned them again really well. Hooked everything back up, and drove it around a bit. The battery is now showing just over 14V instead of just under. And no acceleration lag. I do still have the slightly lumpy idle though. Maybe it’s time to check spark plugs. It’s VERY irregular, though. Doesn’t feel like I’m missing spark in a cylinder.
  2. Going to clean and check terminals yet again. This battery is just over 6mo old. The last one that failed was less than a couple months old. This is frustrating.
  3. Thanks for the reply. I put a new battery in it when I got it. Autozone Duralast Gold. It died 6 weeks later. Autozone swapped it out for me, and I’ve been on the replacement battery ever since. Surely I don’t have two problematic batteries in a row?
  4. Randomly while driving, the dash lights will go nuts and all the door locks will flicker really quickly. When this happens, the battery gauge dips down below 14. This is accompanied by a loss of power. The whole thing lasts for a couple seconds. Also randomly while driving, the engine will idle roughly...kind of feels lumpy for lack of a better term...like it’s a running clothes dryer with a shoe in it. When this happens, it seems to have a major power lag accelerating from a dead stop. I get no CEL from either occurrence. We’ve had it for 8 months. It has 132k miles on it. I’ve searched and so far, I have an idea to replace the ground cable for the battery. Any other ideas?
  5. Yeah, that’s fine. It just makes the marketing confusing. This is supposed to be the tough off-road version. But nope.
  6. I’m unfamiliar with this eLSD...is it similar to Toyota’s A-TRAC system? While the cargo area may be 5” taller, I have a flat load floor in my 2012. I do have to take the 3rd row out, though.
  7. But no 6.2L, no G80 in the rear, not even a solid axle. This is supposed to be the off road version??? Chevy got so close for me and then there are these two glaring issues.
  8. Time to call a lawyer and ask about your state’s lemon laws. Absolutely unacceptable.
  9. I rented a 2020 Yukon XL Denali with the 6.2L for a work trip. Mostly highway miles from middle TN to northwest AR. I only put 87 in it, and drove it for almost 1200 miles. Best single tank of gas: 20.1 mpg Overall trip: 19.8 mpg
  10. I think LT is a fair comparison to an SR5. The difference between the Silverado and the Tundra grows as you move into the higher trim levels, as does the discount off MSRP. HOWEVER...see that 2.7 peeking out from under the 2019 Silverado specs? You’re comparing a 4-cylinder Silverado to a 5.7L v8 Tundra.
  11. I don’t know where you’re getting the idea that the Tundra is a more expensive truck. It is not as feature-rich as the domestics and is cheaper to buy. The Tundra does get the worst mpg for sure, BUT it depreciates the least and has the lowest 5-year cost to own of all the half tons. (See below) Assume $2.15/gal for fuel. The Tundra at 15mpg combined costs $0.143/mile in fuel. After 200k miles, this is $28,600. A new EB Ford at 17mpg combined costs $0.126/mile in fuel. After 200k miles, this is $25,200. The real question is: Is it worth paying thousands more for a new Ford to save $3,400 in fuel after driving 200k miles? Most people simply don’t believe a new Ford will go 200k without significant repairs. But the Tundra, a 13-year-old design, has been shown to get there and beyond with only routine maintenance. Some would rather have the Ford’s bells and whistles that the Toyota lacks. That’s totally fine. But if you want to buy a truck these days and keep it for 15 years, the Toyota is the safest bet to get you there without repair costs. Yes, on paper it lags behind the competition. But that’s exactly why it is the most reliable.
  12. I’m not worried about Toyota’s numbers at all; everyone knows they rate their trucks very conservatively vs the big three. Go look at how much the guys on the Tundra forum punish their trucks—way beyond payload and towing. And they’ll still go 500k miles with only routine maintenance. If I needed to tow 8k+ lbs even semi-regularly, I’d be getting a 3/4 ton Silverado.
  13. Fuel economy isn't really a concern. I was surprised with the numbers I got with the 6.2L, though. I have had great reliability experience with full size GM vehicles. My old 2002 5.3 Suburban went 260k on the original drivetrain before we traded it in. And again, we’re at 130k in our current Yukon XL with no issues. I wonder if the current generation will prove to be as reliable as the others. Also, I do agree that Toyota is generally the reigning king of long term reliability.
  14. Ha. We’re going to drive our 2012 until it won’t go any more. 130k trouble-free miles and counting. But I will be buying a truck probably within the next year. Right now it’s between a 6.2L GMC and a 5.7L Tundra.
  15. Well, I think I’m in love with the 6.2L. This 2020 Yukon XL Denali is super responsive to the skinny pedal. No lag to downshift when I pass someone on the highway. This 2020 also rides far firmer, doesn’t lean into turns or “float” over the road like my 2012. Dig the bucket seats in the second row and the seat coolers (my 2012 only has the lowly seat heaters haha). I also averaged 20.1 mpg on 87 octane fuel, mostly highway miles, on a tank of gas in the 2020 6.2L. My best in my 2012 is 16mpg combined. Lots of 5.3 vs 6.2 threads out there. I’m a believer!!
