Used Chevrolet Impala 9th Gen (2006-2013): Buyer's Guide

The 2009 Chevrolet Impala racked up 824 complaints in NHTSA's database, more than any other year of this generation, with airbag and electrical faults responsible for over 200 of them. By 2013, on the same basic car, that number was down to 270, with zero reported fires. Same nameplate, same W-body platform, a completely different ownership experience depending on which end of the production run you buy.

The 9th generation Impala (2006-2013) was the last car built on GM's W-body platform, a chassis lineage that dated back to 1987. It sold in huge numbers to families, rental fleets, and police departments, which means the used market is flooded with them today at prices that make almost anything else on this list look expensive. It also means you need to know exactly which engine, which model year, and which prior life (retail, rental, or squad car) you're buying into before you hand over cash.

This guide covers the 2006-2013 retail generation only, not the fleet-only "Impala Limited" that GM kept building through 2016 alongside the all-new 10th-generation car.

The 9th Gen Platform

GM redesigned the Impala for 2006 on an updated version of the W-body platform, the same basic front-wheel-drive architecture that had underpinned the nameplate since 1997. It was the final vehicle built on that platform before GM retired it in 2016. Early cars shipped with a 3.5L V6, an optional 3.9L flex-fuel V6, and a 5.3L V8 in the SS trim. The SS and its V8 were dropped after 2009. The biggest mechanical change came for 2012, when GM replaced both V6 options with an all-new 3.6L direct-injection V6 paired to a 6-speed automatic, and simplified the trim lineup to LS, LT, and LTZ. A cosmetic refresh in 2010 brought a new grille, standard dual exhaust tips, and updated interior trim, but the drivetrain didn't change until 2012.

Against its contemporaries, the 9th-gen Impala competed with the Ford Taurus, Toyota Avalon, Hyundai Azera, and the Chrysler 300/Dodge Charger pair, and it was consistently the cheapest of that group both new and used. The Avalon has the reliability edge over the Impala by most owner-survey comparisons, and the 300/Charger twins offer rear-wheel-drive dynamics the Impala never tried to match. What the Impala offered instead was interior space (its W-body architecture packages a genuinely large back seat and trunk for the car's footprint) and a purchase price that undercut all of them, which is exactly why fleets and rental companies bought it by the hundreds of thousands. That fleet volume is the reason used inventory for this generation is so deep today, and also why so many of the cheapest examples come with a prior life you need to account for.

Engines and Known Problems

3.5L V6 (2006-2011)

The 3.5L V6 (RPO LZE, later LZ4) was the base engine across the generation's first six years, rated at 211 hp. It uses a "wet" intake manifold design, meaning coolant passages run directly against the intake gasket. When that gasket fails, which owners on Impala Forums and 1A Auto's technical write-ups describe as a when-not-if event past 100,000 miles, coolant can leak into the crankcase and dilute the engine oil instead of just puddling externally. That's a more serious failure than a simple external leak because diluted oil accelerates bearing wear. RepairPal lists the typical shop repair, using an upgraded metal-frame gasket set rather than the failure-prone original plastic-frame design, at $733 to $857. The engine block and internals themselves have a solid reputation; it's specifically the gasket that fails. Forum posters on Impala Forums specifically flag the original equipment gasket's plastic frame as the root cause and recommend the metal-frame Fel-Pro replacement (part MS 98015 T) as a permanent fix rather than a like-for-like repair, since a second plastic-frame gasket tends to fail again within another 60,000 to 80,000 miles.

3.9L V6 (2006-2011)

The 3.9L flex-fuel V6 (RPO LZ8/LGD) made 233 hp and was standard on the LT 3.9 and LTZ trims. Unlike its 3.5L sibling, it uses a "dry" intake design that doesn't run coolant directly against the gasket, so forum consensus on Impala Forums and go-parts.com's technical guides is that it's less prone to the oil-contamination failure that plagues the 3.5L, though external gasket leaks still happen. It's the engine to look for if you want the intake-gasket risk minimized without stepping up to the newer 3.6L. Flex-fuel capability means it'll run on E85, though most owners report running standard gasoline for the better fuel economy. The 3.9L was reserved for the LT 3.9 and LTZ trims rather than the base LS, so if the lower-risk intake design matters more to you than saving a few hundred dollars on a base-trim 3.5L, shop by trim first and engine second.

5.3L V8 (2006-2009, SS only)

The Impala SS paired a 303 hp, 5.3L V8 (RPO LS4) with GM's Active Fuel Management cylinder deactivation, an unusual choice because it's a front-wheel-drive application for an engine normally found in rear-drive trucks and Corvettes. Forum threads on LS1Tech, ImpalaSSForum, and CorvetteForum all converge on the same weak point: the 4T65E-HD transaxle wasn't originally engineered around this much torque, and owners report average transmission life in the 60,000 to 80,000 mile range under normal driving, less under hard use. The engine itself holds up well. If you're looking at an SS, budget for a transmission rebuild or verify one's already been done, and check for the same intake manifold gasket leak that affects the V6s; ImpalaForums and Chevy Enthusiasts Forums both document 5.3L intake gasket failures on these cars too. The SS is also the rarest trim of the generation by a wide margin, since it was a low-volume halo model sitting well above LS, LT, and LTZ pricing when new, so expect a smaller pool of listings and more variance in condition than with the mainstream trims.

3.6L V6 (2012-2013)

The direct-injection 3.6L V6 replaced both older V6 options for 2012, rated around 300 hp and paired exclusively with a 6-speed automatic. GM Inside News forum threads spanning years of owner reports single out a specific quirk: the 2012 model carried over earlier-design timing chain hardware and an oil-life-monitor calibration that let intervals stretch too long, which starves the chain guides of fresh oil and can lead to chain stretch and a rattling cold-start noise. GM revised both the timing chain hardware and the oil life monitor calibration for 2013, tightening it to prompt changes by around 7,500 miles. If you're choosing between a 2012 and a 2013 with similar mileage and price, the 2013 is the safer bet on this specific point. Separately, GM sent Special Coverage letters, not an NHTSA recall, to some 2011-2013 owners covering a wheel-speed-sensor wiring fault that can trip StabiliTrak, traction control, and ABS warning lights together, sometimes with a grinding noise and a moment of power loss while turning. Affected vehicles got coverage extended to 120,000 miles or 10 years; a related class-action lawsuit covering 2010-2016 Impala and Impala Limited models was dismissed by a federal judge in 2020. Ask whether this repair was already done.

Trim Levels

Ex-police and ex-rental Impalas make up a real slice of the used inventory for this generation, and it's worth treating them as their own category rather than assuming they're identical to a retail car. The 9C1 police package added an oversized cooling system and heavier-duty suspension and brake components, which can mean a more durable chassis than a comparable civilian LS or LT that spent its life idling in a driveway. The tradeoff is duty-cycle wear: idle hours, hard acceleration and braking, and interior abuse that a retail car never sees. Confirm the "9C1" code on the vehicle's build tag if a seller claims police history, and budget for the same transmission scrutiny as any other trim, since forum reports on Impala Forums and Grand Prix Forums describe the 4T65E as no more forgiving in a squad car than in a rental fleet sedan.

Which Model Years to Target Within This Gen

One of the recalls counted for 2008, 2009, 2011, and 2012 (campaign 12V377000) applies only to police-package vehicles, not civilian retail cars, so a non-police Impala from those years effectively carries one fewer real-world exposure than the table suggests.

NHTSA's complaint data backs up what the forums say anecdotally: the 2007 through 2009 model years logged 627, 810, and 824 complaints respectively, with crash counts in the 40s and 50s and a reported death each year, concentrated in airbag and electrical system categories. By 2011 through 2013, annual complaint counts dropped to 505, 258, and 270, with crash counts falling into the teens and twenties and zero reported deaths. The 2013 is the best overall pick here: it has the fewest recalls, the most-resolved 3.6L drivetrain, and NHTSA's cleanest complaint record of the generation. If you want the SS and its V8, you're locked into 2006 through 2009 regardless, so budget for the transmission and gasket work those years are known for. One quirk worth knowing if you're cross-shopping late-model years: 2013 was the last model year in this generation to offer a front bench seat with a column-mounted shifter, a full-size-sedan configuration that had all but disappeared from the market by then. If that layout matters to you, it narrows your search to 2013 specifically.

Pre-Purchase Inspection Checklist

For 3.5L and 3.9L V6 cars (2006-2011):

• Pull the oil dipstick and check for a milky, coffee-with-cream tint. That's coolant in the oil, the telltale sign of a failed 3.5L intake gasket, and it means engine damage may already be underway. Walk away from anything showing this.
• Check the coolant reservoir level cold, then run the engine to temperature and check again. A slow, steady drop with no visible puddle points to an intake gasket leak, more likely on the 3.5L than the 3.9L.
• Ask if the timing chain kit has ever been serviced; these engines are generally reliable in this respect, but a full maintenance history matters more than the specific mileage number given how many of these cars have unclear service records.

For the 5.3L V8 SS (2006-2009):

• Have the transmission fluid checked for color and smell. Dark or burnt-smelling fluid on a 4T65E-HD past 60,000 miles is a warning sign specific to this trim's known weak point.
• Feel for a delayed or flared 1-2 shift during the test drive. That's the earliest symptom forum threads consistently point to before a full transmission failure.
• Check for the same coolant-in-oil sign described above; the V8 shares the intake gasket failure mode.

For the 3.6L V6 (2012-2013):

• Start the car cold and listen for a rattle from the timing chain area for the first few seconds before it quiets down. This is more common on 2012 cars with the carryover chain hardware than on 2013 cars.
• Ask for maintenance records showing oil changes at or before the interval the dash indicated. Owners who let the pre-2013 oil life monitor run too long are the ones reporting chain stretch.
• Test the StabiliTrak, traction control, and ABS systems by making a few tight turns at low speed and watching for warning lights or a grinding noise, and ask whether the wheel-speed sensor wiring coverage was ever performed.

For any year:

• Verify whether the car has police or fleet history through a VIN check or the 9C1 build tag, since it changes what wear patterns to expect.
• Check both headlight assemblies for fogging or visible water droplets. Impala Forums has multiple threads on condensation forming inside the factory headlight housings; it's more of a nuisance than a safety issue but points to a compromised door seal.
• Open and close the trunk a few times and listen for a rattle from the rear parcel shelf area, a common complaint on Impala Forums tied to loose trim clips rather than a structural issue.
• Run the VIN through CarScout's recall lookup tool to see which of that specific car's campaigns have been completed. Don't ask a seller to "confirm" any recall was done without checking it yourself first.

Running Costs

EPA combined fuel economy is nearly identical across the 3.5L, 3.9L, and later 3.6L despite the newer engine's extra 90 hp and two extra gears, which tells you where GM spent the efficiency gains: performance, not the window sticker. GM issued a Special Coverage bulletin extending water pump warranty coverage to 10 years or 150,000 miles on some model years after owners reported premature failures across the generation; ask whether a car's pump has already been replaced. Insurance on a 9th-gen Impala is generally inexpensive given the car's age and full-size sedan safety ratings, though an SS with the V8 may carry a modest performance surcharge.

Brakes and tires are otherwise unremarkable for the class: this is a conventional front-wheel-drive sedan on strut and multi-link suspension, so parts are common, inexpensive, and available from any parts store rather than requiring dealer-only sourcing. The biggest line-item variance between cars of this age isn't routine wear items, it's whether the intake gasket, water pump, and (on the SS) transmission work has already been done by a previous owner. A car with that maintenance already behind it is worth more than the mileage alone would suggest, and a car without it is a repair bill waiting to happen regardless of the asking price.

FAQ

Is the 9th gen Chevy Impala 3.5L V6 reliable? The engine itself is durable, but the intake manifold gasket is a wet design that can leak coolant into the oil, typically past 100,000 miles. Budget $733 to $857 for the repair with an upgraded gasket. Outside of that specific failure, the 3.5L has a solid reputation for longevity.

What year Impala should I avoid? The 2007 through 2009 model years logged the highest NHTSA complaint counts of the generation, 627 to 824 a year, concentrated in airbag and electrical faults. They're not unsafe to drive today with recalls completed, but expect more electrical gremlins than a 2011-2013 car.

How many miles does a 9th gen Impala last? Typical used listings for this generation run 130,000 to 145,000 miles, and well-maintained examples with documented oil changes and timely gasket or transmission work regularly exceed 200,000 miles. The engines outlast the transmissions and gaskets in most cases.

Is the Impala SS with the 5.3L V8 worth buying used? Only if you accept the transmission risk. The 4T65E-HD transaxle behind the 303 hp V8 averages 60,000 to 80,000 miles before major issues in forum reports, since it wasn't originally designed around V8 torque in a front-wheel-drive car. Budget for a rebuild or verify one's been done.

Should I buy an ex-police 9th gen Impala? The 9C1 police package adds heavier-duty cooling, suspension, and brakes, which can mean a more durable chassis. The tradeoff is duty-cycle wear from idle hours and hard use. Confirm the 9C1 code on the build tag and inspect the transmission the same way you would on any other trim.

How many used Chevrolet Impalas are for sale right now? As of September 6, 2026, CarScout's market data tracked 400 used 2007-2013 Chevrolet Impala listings nationwide. Current counts and per-year breakdowns are on the Chevrolet Impala market page.

The Bottom Line

As of September 6, 2026, CarScout was tracking 400 used Chevrolet Impala listings nationwide across the 2007-2013 model years, with median mileage running from about 131,000 miles on 2013 cars to about 144,000 miles on 2007 cars. These are high-mileage, inexpensive cars by now, and the right one depends entirely on which engine and which model year you land on. A 2013 LTZ with the 3.6L V6 and documented oil changes is the strongest all-around pick in this generation. If you want the V8 SS, go in accepting the transmission risk as a known cost of entry. Whatever year you're looking at, run the VIN through a recall check before you commit, and if you're set on this exact spec, CarScout's Chevrolet Impala market page tracks current listings and per-year pricing so you're not starting your search from scratch.
