Kestrel Take

A cheap, roomy, simple pushrod-V6 sedan with 441 complaints, and the three biggest clusters are all things a buyer can act on. Thirty percent is the electrical system, which on this car is the ignition-key recall (14V355) — a heavy key ring can turn the key out of Run, killing the engine, the power steering and the airbags at speed — plus gauges dropping out. Twenty-three percent is the airbag light, most of it the passenger seat sensor whose wires the seat frame chews through (recall 16V507). And 22% is the 'Service StabiliTrak / Engine Power Reduced' cascade that cuts the car to a crawl or stalls it in traffic, usually a throttle body or its wiring. The 4T65-E transmission adds a real four-figure risk. Four recalls, three fires, 18 crashes. None of this makes it a bad buy at four or five thousand dollars; it makes it a car you buy only with the recalls shown closed on the VIN, a scan for stored codes, and a firm test drive with every warning light watched.

What we checked

Reconciled against public records, 2026-09-25

NHTSA holds 441 owner complaints for the 2010 Chevrolet Impala, and 4 recall campaigns.

A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. The largest single group is electrics and electronics at 30%. That is notable without being overwhelming — worth checking, not worth panicking about.

4 recall campaigns cover this model year. Recalls are repaired free, for any owner, with no time limit on most safety campaigns — but only if someone books it in. Ask the seller to show it was done, or have any dealer check the VIN; it takes them a couple of minutes and costs nothing.

Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.

Known Issues for the 2010 Chevrolet Impala

Ranked by wallet impact. These are documented, recurring problems — not freak accidents. How we decide that.

Ignition key can turn out of Run from a heavy key ring — engine, steering assist and airbags all go dark (recall)High — wallet impact

The largest cluster on the car: 132 electrical complaints, 6 crashes and all 3 of the record's fires. The core of it is recall 14V355, GM's 2014 ignition campaign: the key can rotate out of the Run position if the ring is heavy or the driver's knee catches it, which shuts the engine off while moving, takes the power steering and brake assist with it, and can stop the airbags firing in the crash that follows. The fix is two small key rings and an insert or cover for the key, free at any GM dealer, and owners also describe keys stuck in the ignition and complete losses of power at 65 mph that dealers could not reproduce. The rest of the cluster is the instrument cluster and gauges dropping to zero or freezing mid-drive, and a passenger airbag light that flickers with the seat. Check the recall on the VIN, then drive it with only the key on the ring and, on a quiet road, tap the key gently with your knee.

Repair cost: $0 with the recall — verify it was performed; $150–$400 for an ignition switch or cylinder outside it

'Service Airbag System' light — passenger seat sensor wires chafed by the seat frame (recall)High — wallet impact

102 airbag complaints, 11 of them crashes with no deployment, and the everyday version is the light: 'Service Airbag System' comes on, the passenger airbag indicator flips between On and Off as someone shifts in the seat, and the dealer wants $130 to look. Recall 16V507 explains most of it on cars built April 25, 2008 to February 16, 2010: the front passenger seat frame rubs through the passenger presence sensor's wiring, and a damaged wire can switch the airbag off with someone sitting there. Dealers wrap the wires in anti-abrasion tape and replace any that are damaged, free. A light that comes on when the driver's seat is slid back is the same story on the other side — a connector under the seat. Run the VIN, then turn the key to Run and watch the airbag lamp go out within a few seconds; it must not stay on or flicker when a passenger moves.

Repair cost: $0 with the recall — verify it was performed; $300–$900 for a sensor mat or harness outside it

'Service StabiliTrak / Traction Control / Engine Power Reduced' — the car crawls or dies in trafficHigh — wallet impact

Three clusters tell one story: 95 stability-control complaints, 47 speed-control and a good share of the 94 engine filings describe the same sequence — a hard jerk at speed, then Service Traction Control, Service StabiliTrak and Engine Power Reduced on the display, the car limited to a crawl, and in some cases cutting out in the middle of the street until it is switched off and back on. The usual cause on this V6 is the electronic throttle body or its connector — corroded pins, a chafed harness, or a worn accelerator-pedal position sensor — and a scan tool shows a P2135-family throttle code when it happens. Some owners replaced most of the front suspension chasing the lights before anyone read the codes. Ask for the stored and history codes; on the test drive, hold a steady 50 mph for a few miles and then accelerate hard, watching the display.

Repair cost (estimate): $150–$700 for a throttle body or pedal sensor; $500–$1,200 if the harness needs repair

4T65-E four-speed automatic — hard shifts, slipping, and loss of gears from a broken wave plate or a failed pressure solenoidHigh — wallet impact

67 power train complaints, 15% of the record. The 4T65-E behind both the 3.5L and 3.9L has two well-known ways to fail on this generation: the pressure control solenoid wears and the transmission bangs into gear or shifts harshly and late, and the 3-5-reverse clutch wave plate can crack, which shows first as a slip or flare shifting into third and ends with no third, fourth or reverse at all. GM ran a special coverage on the wave plate for some earlier W-body cars — ask a Chevrolet dealer whether this VIN was ever covered, and do not assume it was. The solenoid is a few hundred dollars; the wave plate is a rebuild. On the drive, feel every shift cold and warm, then reverse up a slope and confirm it engages without a delay.

Repair cost (estimate): $300–$700 for a pressure control solenoid; $1,800–$3,200 for a rebuild — around 61% of what this car is typically worth

Front seat belt anchors may not have been secured to the pretensioners (recall)Medium

Recall 10V480 covers 2009–2010 Impalas: the front seat belt webbing may not have been properly attached to the lap-belt anchor pretensioner, so the belt might not hold in a crash. Dealers inspect both front belts and reinstall the anchors if needed, free. It was an early recall, so most cars have had it, but a 2010 has passed through several owners by now and the VIN lookup takes seconds. A second campaign on the list, 12V377, replaces front lower control arms on police-package cars only; a civilian Impala is not in it, but if you are looking at an ex-fleet car, check.

Repair cost: $0 with the recall — verify it was performed

Steering goes heavy when the engine cuts out, plus a clunk from the intermediate shaftMedium

42 steering complaints, and many are the downstream half of the ignition and reduced-power stories: the engine dies, the hydraulic pump stops, and the wheel turns to concrete at 40 mph — three of these are crashes. The other thread is a knock or clunk felt through the wheel over bumps and when turning at parking speed, which on this generation is usually the intermediate steering shaft; GM has serviced them with a lubrication kit or a replacement shaft. Neither is a reason to walk away on its own. Turn lock to lock at a standstill and listen, then drive over a rough patch with a light grip on the wheel.

Repair cost (estimate): $150–$450 for an intermediate shaft; $400–$900 for a power steering pump
