Every generation: what ownership is like, what breaks at what mileage, what repairs cost, and what to check before you buy.
The Sierra 1500 is the Silverado's twin, and 'which years' is the question every search turns up. The answers conflict: lists name the 2003-2007 trucks, 2011, 2014 or 2015-2017. That conflict is the clue: the problems follow the engine and the transmission, not just the year.
Four repairs come up again and again. The factory brake lines on 1999-2007 trucks rust. The 5.3L V8's cylinder-deactivation lifters can fail and run into the thousands. The 2007-2018 six-speed and 2015-2019 eight-speed automatics both have known patterns. On newer trucks, recalls matter more than wear. Each is priced below with sources. Many of those sources priced the Silverado, and we say so item by item.
This page walks each generation: what breaks at what mileage, what the repair costs, what to check when you're standing in front of one. We also show our own numbers (NHTSA complaints per catalog listing and how often ads mention a problem), always with the denominators.
problems cluster by generation, not by badge — know which one you're looking at
NHTSA complaints per catalog listing fall steeply across this generation, from 30.3 for 1999 (758 complaints across 25 listings) to 1.6 for 2006 (203 across 131). The generation median is 5.5. 1999 is 5.6 times that median but we track only 25 listings for it, below the 30 our rule requires, so it is not flagged. 2000 is 14.1 per listing (2.6 times the median), but 8 of 35 enriched ads (22.9%) mention a problem against a 25.3% median, so it is not flagged either. Older model years have had longer to collect complaints, which is part of why the early years look high. For 1999-2008 we dropped NHTSA records tagged 2500 or 3500 so the counts match half-ton trucks. The sourced patterns below are rusted brake lines and the 4L60E automatic.
| Miles | Item | Cost | Notes |
|---|---|---|---|
| Not verified (age and road salt, not mileage) | Rusted brake lines (1999-2007 GM half-ton trucks) | $600-$2,500 (au7o, 2006 Silverado 1500 page; shared GM platform). One forum owner was quoted $1,100 in Massachusetts; another cites $600 for labor alone on an '05 2500, lines not included. | chevytrucks.org calls the factory brake lines on these trucks 'very prone to rusting out', worse in salt states. All three sources name the Silverado; the Sierra is the same truck on the same platform, so we say 'shared GM platform' rather than claim a Sierra-specific price. Look at the hard lines along the frame rails and over the rear axle; a leak or a soft pedal on a truck this old needs the lines replaced before anything else. |
| Not verified | 4L60E automatic transmission wear | Rebuild $2,200-$3,400 (Creech Import, citing RepairPal for the Raleigh area; Silverado figure, shared GM platform). | au7o lists the 4L60E among the more serious known issues for the 2006 truck. Ask for service records, check the fluid colour and smell, and watch for flare or slip between gears on a test drive. |
| any | Tailgate support cable corrosion (recalls 04V129000, 06V066000) | Free at a GMC dealer when the recall is open | NHTSA says the galvanized steel cables that hold the tailgate open can corrode and fracture when loaded. NHTSA lists both campaigns on Sierra model years 1999-2004. Check the tailgate by VIN at nhtsa.gov/recalls and look at the cables. |
| any | Steering shaft bolt (05V018000), fuel rail screws on 5.3L (04V376000), unwanted ABS activation (05V379000) | Free at a GMC dealer when open | 05V018000: the bolt joining the intermediate steering shaft to the steering gear may not meet specification and could fracture. 04V376000: on 5.3L (RPO L59) engines the fuel rail crossover tube retainer screws may break. 05V379000: unwanted antilock brake activation on certain pickups, listed on 1999-2002 Sierras. Confirm each by VIN. |
NHTSA complaints per catalog listing in this generation run from 0.84 for 2012 (152 complaints across 180 listings) to 3.46 for 2008 (471 across 136). The generation median is 2.52. No year reaches twice the median: the highest, 2008, is 1.4 times it. The top complaint areas are air bags, brakes and electrical in the early years, and air bags and structure later; air bags line up with the inflator recalls below. NHTSA files some of these years under 'Sierra 1500 Hybrid' as well as 'Sierra 1500' (2010 appears only under the hybrid name), so we combined the records; without that, 2010 and 2012 would look nearly complaint-free. Several 'years to avoid' lists point at the AFM years generally; we flag by rule, and none trips it.
| Miles | Item | Cost | Notes |
|---|---|---|---|
| often cited before 100K; some owners report 180K-220K with no issue (Marin Mazda, Silverado page) | 5.3L/6.2L AFM (cylinder deactivation) lifter failure | $2,600-$4,800 (avturo, independent shop; Silverado figure, shared GM platform); $3,000-$4,500 for lifters on both banks (Capital Motorcars); $3,200 for a lifter repair against $7,000+ for an engine overhaul if a ticking lifter is ignored (Autos of Chicago). Go-Parts has a Sierra-specific 1999-2015 lifter guide that confirms the pattern on 2007-2015 trucks. | Typical sign is a ticking or misfire (a lifter that has collapsed). Go-Parts says lifters on 2007-2015 Sierras with AFM are designed to collapse on command, which is where the failures come from. Marin Mazda reports 2011-2013 trucks do better than earlier AFM years but are not immune. Ask whether the lifters or the engine were ever replaced, listen at a cold start, and check for a misfire code. Our ad-mention counts are not failure counts. |
| often noted by about 120K (Eskimo Auto Repair) | Oil consumption on 2007-2013 5.3L (piston rings with AFM) | Not verified: no repair price found for a ring job; owners report adding about a quart per 1,000 miles (Rohnert Park Transmission, a Silverado page; shared GM platform) | Apex Tech Nation says the 2007-2013 ring design controls oil poorly on the AFM cylinders; Rohnert Park Transmission says class actions have been filed. Check the dipstick, ask how often the owner adds oil, and look at the tailpipe for blue-grey soot. |
| 100K-150K for the wave plate (Transmission Repair Cost only) | 6L80 six-speed automatic: wave plate and torque converter wear | Wave plate job $1,400-$2,200 independent / $2,000-$3,000 dealer; full rebuild $2,500-$4,000 (Transmission Repair Cost) or $3,800-$4,900 (Creech Import, citing RepairPal, Raleigh). Silverado figures; same transmission, shared GM platform. | Coretransmissionparts calls the wave plate the most common 6L80 failure and describes a harsh 1-2 shift, then loss of 4th gear; Transmission Repair Cost names the 3-5-reverse plate. The two shops disagree on which plate, so we say only 'wave plate'. au7o adds a separate control-module (TEHCM) fault that sends the truck into limp mode. Ask for fluid-service records. |
| any | Passenger air bag inflator recalls (21V050000, 21V051000, 21V052000, 21V053000, 21V054000) | Free at a GMC dealer when open | These cover passenger-side inflator modules on 2007-2014 Silverado 1500, Sierra 1500 and related trucks; which VINs are included varies by campaign. Check the exact VIN. |
| any | 2011 rear axle cross pin recalls (10V643000, 11V007000) | Free at a GMC dealer when open | 10V643000 names 2011 Silverado LD and Sierra LD trucks. The cross pins were not properly heat treated and could fracture and displace, locking the rear axle. Covers certain 2011 trucks only. |
Leaving out 2016 (see below), NHTSA complaints per catalog listing run from 0.88 for 2018 (305 complaints across 345 listings) to 2.74 for 2014 (863 across 315). The generation median is 1.42. 2014 is 1.9 times that median, just under the 2.0 cutoff, so it is not flagged. 2016 shows only 50 complaints against 818 for 2015 and 431 for 2017. We tried the other NHTSA name variants and found nothing more, so we treat 2016 as a gap in NHTSA's indexing and give it no flag either way; its figure of 0.18 per listing should not be read as a clean year. The 2014 complaints include exterior lighting and brakes, and recall 17V414000 below covers a power steering assist loss on some 2014 trucks. Several 'years to avoid' lists point at 2014-2017; none of those years is flagged by our rule.
| Miles | Item | Cost | Notes |
|---|---|---|---|
| Not verified | 8L90 eight-speed automatic: shudder and torque converter (2015-2018 trucks with the 8-speed) | Fluid flush with the updated Mobil 1 LV ATF HP plus a reflash $400-$700 dealer / $300-$500 independent; torque converter $1,200-$2,200 independent / $1,800-$2,800 dealer (Transmission Repair Cost); a 2018 Silverado estimate of $960-$2,170 for the converter (Fixxr); rebuild $2,800-$4,200 (Transmission Repair Cost). All sources price the Silverado; shared GM platform. | Transmission Repair Cost describes a shudder under light throttle at low speed, handled by GM bulletins and a class action settlement; ask for the VIN's bulletin and fluid-service history. Pensacola Truck Transmission puts an inspection at about $125 and a fluid flush around $350. If the shudder returns after the fluid update, the converter is the next step. |
| often cited before 100K (Marin Mazda; some owners report 180K-220K with no issue) | 5.3L/6.2L AFM/DFM lifter failure | $2,600-$4,800 (avturo, independent shop; Silverado figure, shared GM platform); $3,000-$4,500 both banks (Capital Motorcars); $3,200 lifter repair against $7,000+ for an engine overhaul if ignored (Autos of Chicago). | The same cold-start tick and misfire pattern as Gen 2. Go-Parts has a Sierra-specific guide that runs through 2015. Ask whether the lifters were ever replaced and scan for misfire codes. |
| 100K-150K (Transmission Repair Cost only) | 6L80 six-speed automatic (2014-2018 trucks with the 6-speed): wave plate | Wave plate job $1,400-$2,200 independent / $2,000-$3,000 dealer; rebuild $2,500-$4,000 (Transmission Repair Cost) or $3,800-$4,900 (Creech Import, citing RepairPal, Raleigh). Silverado figures; shared GM platform. | Same unit and same pattern as Gen 2. Ask for fluid-service records and watch for a harsh shift or lost gear. |
| any | Electric power steering assist loss (recalls 17V414000, 18V586000) | Free at a GMC dealer when open | 17V414000 covers certain 2014 Silverado 1500 and Sierra 1500 trucks that may have a temporary loss of power steering assist; 18V586000 covers certain 2015 trucks where assist may be lost momentarily and then return suddenly. |
| any | Brake vacuum pump (19V645000) and ABS software (19V761000) | Free at a GMC dealer when open | 19V645000: on 2014-2018 trucks the vacuum pump's output may fall over time, which can reduce brake assist. 19V761000: on 2014-2018 1500s with the 5.3L, a 3.08 rear axle and four-wheel drive, a failed wheel-speed sensor can cause the ABS software to activate the brakes at 41-60 mph. |
| any | Front upper control arm welds (16V256000, 2016-2017 trucks) | Free at a GMC dealer when open | NHTSA says the front upper control arms may have inadequate welds near the bushing. The recall summary names the GMC Sierra along with the Silverado, Escalade, Tahoe and Yukon; it runs 2016-2017 for the Silverado, and our database files it under the Sierra for 2016. Confirm by VIN. |
NHTSA complaints per catalog listing run from 0.34 for 2025 (124 complaints across 367 listings) to 2.66 for 2019 (658 across 247). The generation median is 1.73. No year reaches twice the median: the highest, 2019, is 1.5 times it. Our data has no enriched-ad count for 2025 or 2026, and the newest model years have had little time to collect complaints, so their low figures say little yet. The top complaint area is the engine in every year, which lines up with the recalls and lifter reports below.
| Miles | Item | Cost | Notes |
|---|---|---|---|
| some reports within the first 20K miles on 2020+ trucks (Rohnert Park Transmission, Silverado page); others later | AFM/DFM lifter failure on the 5.3L/6.2L (2019 and later) | $2,600-$4,800 on a 2020 Silverado (avturo, independent shop; shared GM platform); $3,000-$4,500 both banks (Capital Motorcars). Rohnert Park Transmission gives no price. Autos of Chicago's 2027 guide covers 5.3L/6.2L trucks from both brands. | Cylinder deactivation is now called DFM (dynamic fuel management) on newer trucks. Listen for a tick at a cold start and scan for misfire codes. Anything under warranty is a dealer matter; ask what coverage is left. |
| Not verified | 10L80 ten-speed automatic: harsh shifts and bulletins | Rebuild $3,000-$4,500 (Transmission Repair Cost, Silverado page; shared GM platform). | Transmission Repair Cost says the unit is too new for a definitive reliability profile and that bulletins suggest harsh-shift complaints similar to Ford's 10R80. Mostly a warranty question on newer trucks. |
| any | 6.2L V8 connecting rod and crankshaft recall (25V274000, 2021-2024) | Free at a GMC dealer when open | GM says connecting rod or crankshaft components on certain 6.2L gas V8 trucks, including the Sierra 1500, may have manufacturing defects that can lead to engine damage and failure. Check the VIN; this applies only to the 6.2L. |
| any | Diesel transmission control valve recalls (24V797000, 26V083000, 2020-2022 diesel trucks) | Free at a GMC dealer when open | The transmission control valve may fail and cause the rear wheels to lock up; 26V083000 (February 2026) covers trucks that may have been repaired incorrectly under 24V797000. Both name the Sierra 1500. Applies to diesel trucks. |
| any | Other recalls: driveshaft (20V650000), fuel pump (19V837000), transfer case (26V289000) | Free at a GMC dealer when open | 20V650000 (2019-2020): a driveshaft joint may not have been properly welded and the shaft can separate. 19V837000 (2020): the fuel pump may be missing a pressure regulator. 26V289000 (2026, 4WD/AWD): a missing transfer case component may lock the wheels. All three name the Sierra 1500. |
| Variant | Years | What it means for a buyer |
|---|---|---|
| Sierra HD (2500 / 3500) | Not covered on this page | Heavy-duty trucks use different engines and transmissions. Our NHTSA counts exclude them, and repair figures here are for 1500-series trucks. |
| Chevrolet Silverado 1500 | 1999 to present | The Sierra's twin on the same platform and powertrains. Several repair prices on this page come from sources that priced the Silverado; where that is the case, the item says 'shared GM platform'. |

We don't tell you to skip a year; we flag by a fixed rule (see 'Years flagged' in each generation), and no Sierra 1500 year trips it. The closest calls: 1999 has 30.32 NHTSA complaints per catalog listing (758 complaints across 25 listings) against a Gen 1 median of 5.46, but 25 listings is below the 30 our rule needs. 2000 is 2.6 times the median but 8 of 35 enriched ads (22.9%) mention a problem against a 25.3% median, so it fails the second test. 2014 sits at 2.74 per listing against a Gen 3 median of 1.42, 1.9 times, just under the 2.0 cutoff. Ad mentions are not confirmed failures.
It depends on the engine and generation. Gen 1 (1999-2006): rusted brake lines and 4L60E wear. Gen 2 (2007-2013): AFM lifter failure and oil consumption on the 5.3L, and the 6L80 automatic. Gen 3 (2014-2018): the 8-speed shudder, lifters, and recalls for power steering assist and brake vacuum. Gen 4 (2019 on): lifter reports, 10-speed shift complaints, and recalls. Each is priced, with sources, in the generation sections.
Avturo puts a 5.3L/6.2L lifter job at $2,600-$4,800 at an independent shop. Capital Motorcars gives $3,000-$4,500 for lifters on both banks, and Autos of Chicago gives $3,200 for a lifter repair against $7,000+ for an engine overhaul if a ticking lifter is ignored. Those prices come from Silverado-focused pages; the engine is shared, but they are shop figures, not a quote for your truck.
Owners and shops report a shudder under light throttle on 8L90 trucks (2015-2019). Transmission Repair Cost, writing about the Silverado, says GM handled it with bulletins and a class action settlement; the usual fix is the updated fluid and a reflash ($400-$700 dealer, $300-$500 independent), then a torque converter ($1,200-$2,200 independent, $1,800-$2,800 dealer) if it persists. We don't have a failure rate, only these reports. Ask for the VIN's service history.
We don't have a mileage figure we could verify from two sources, so we won't give one. What we can show: lifter failure is reported before 100K miles on some trucks and not on others (Marin Mazda reports owners at 180K-220K with no major issues), and the 6L80 wave plate is reported at 100K-150K miles (one source). Service records tell you more than the odometer.
Mechanically close. CarBuzz and Wikipedia describe the Sierra as the Silverado's twin from 1999, sharing platforms (GMT800, GMT900, K2XX, T1XX) and engines. GMC numbers its generations differently, because the Sierra name began in 1988, so the 1999 truck is its second generation. That is why many of the repair prices here come from Silverado sources.
