What to check before you buy a 2021 Chevrolet Tahoe

A useful visit to this page takes five minutes. YearTell does not score years and cannot see the vehicle in front of you.

  1. Look up the VIN for open recalls at nhtsa.gov. This year has 16 campaigns on file below.
  2. Engine. Have a shop check for oil consumption, coolant leaks, rough idle and unusual engine noise.
  3. Fuel system. Check for fuel smell, leaks and whether it starts and idles cleanly.
  4. Transmission / driveline. Have a shop drive it and check the transmission: hard or delayed shifts, burnt-smelling fluid, and 4WD engagement if equipped.
  5. Skim a few owner reports below for Engine. Look for the same symptom repeating.
  6. Take that list to a mechanic. Do not turn the complaint total into a score.

The lifters are tapping on my vehicle and the engine also has a shutter to it. I am also not getting 5000 miles per oil change by 5000 miles my vehicle is showing add engine oil and is taking 2qts to get it back showing on the oil stick.

CrashFireInjuryDeath
My vehicle had a pop and loss of power on the highway. After pulling over, I did not have a check engine light but did connect my code reader and found a P308. I felt unsafe to drive so I had it towed to a shop. I later found out the DOD system or lifter on valve #8 has failed and needs replacement. Factory recommends oil change at every 7k miles, I did them at 4K. My oil pressure was up to par with the small window of real time allowable oil pressure. The design was great on paper but one of the worst engines GM has ever made. I sincerely hope there is enough people complaining about these 2021 GM 6.2 & 5.3 engines!!

Nearly new Chevrolet Tahoe in 2021 with less than 4,000 miles had an engine failure due to defective valve lifters that required a significant repair and lengthy out of service period (replaced valve lifters in one bank). Now in 2026 the same vehicle's engine has failed for the same reason and the engine needed to be replaced.

6.2L engine failure. Camshaft and lifters. My [XXX] wife ([XXX]) was driving and it shut off going down the highway. It is at my local Chevrolet dealer getting repaired. No warnings. No engine light. Vehicle has 88,000 miles on it, I purchased it April 22, 2026 with 84,700 miles on it. My Chevrolet App says there are no issues with the vehicle..it’s in pieces at the dealership. I had higher standards for a high country. Always owned Chevrolets. May be my last one. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Frequently asked questions

What are the most common problems on the 2021 Chevrolet Tahoe?

Owners named Engine most often — 112 of 443 reports (25%). That is the NHTSA file, not a diagnosis of every vehicle.

Are there recalls for the 2021 Chevrolet Tahoe?

NHTSA lists 16 safety recall campaigns. They were filed about Fuel system, Seat belts, Airbags, Steering, Brakes, Transmission / driveline, Lights, and Engine. Check the VIN at nhtsa.gov; a campaign on this page can still be open on a specific vehicle.

What should I inspect before buying a 2021 Chevrolet Tahoe?

Look up the VIN for open recalls. Have a shop check for oil consumption, coolant leaks, rough idle and unusual engine noise. Then skim owner filings for the same symptom and take that list to a mechanic.

Does a high complaint count mean I should skip this year?

No. Counts are reports people chose to file and they are not adjusted for sales volume. YearTell does not publish scores or a list of years to skip. Inspect the vehicle.
