What stands out
No new NHTSA powertrain complaint has been filed on this vehicle in over 12 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This informational bulletin explains Unscheduled Supplemental Services and the importance of GM Simplified Maintenance Schedules.

The failure pattern owners describe
Owners of the 2012 Camaro describe multiple powertrain failures that dealerships struggle to diagnose and fix. Torque converter problems top the list: vehicles shudder and jerk during acceleration, especially between 1,200 and 2,500 RPMs, or at specific speeds (31, 42, and 53 mph). One owner had metal shavings flushed from the transmission after converter replacement, yet hesitation and harsh shifting continued; another's converter failure recurred despite repair.
Manual transmission owners report clutch pedals sinking to the floorboard without warning as early as 4,300 miles. One owner had the clutch replaced once, only for it to fail again days later. Another needed six separate clutch replacements at the dealer.
Two owners describe sudden engine seizure with no warning lights. One experienced complete shutdown while driving at 30 mph after the engine had been inspected three weeks prior. Another found metal-colored shavings in fresh oil and no oil pressure warning before the engine locked up at 50,000 miles.
A convertible owner's vehicle became completely undriveable when water from the convertible top damaged the entire electrical system, killing all brake lights and power.
Notably, many issues come with no diagnostic codes or can't be replicated during test drives, yet the problems persist. Dealerships often declare symptoms normal for the transmission type.

Failure modes owners describe
Torque Converter Failure
Multiple owners report vibration, shuddering, jerking, and hesitation during acceleration tied to torque converter malfunction. One owner had metal shavings found in transmission fluid after converter replacement; the same owner continued experiencing transmission problems post-repair (hesitation, harsh downshifts, returning vibration). Another owner's torque converter failure recurred even after dealer repair.
When: 6,000–17,000 miles; issues escalate over weeks to months of driving
Symptoms owners cite: Shuddering/vibration during gradual acceleration; Violent jerking at highway speeds (45 mph); Hesitation when attempting to shift or accelerate; Engine feels like it will stall during gear changes; Downshifting without reason; Metal knocking/scraping sounds; Roughness in automatic and manual shift modes
Codes mentioned: Multiple unidentified error codes (one owner reported five codes)
Repairs/costs cited: Transmission flush due to metal shavings; torque converter replacement at dealership; repeat failures despite repair; dealerships claim post-repair symptoms are 'normal' for the transmission type
Clutch Pedal Failure (Manual Transmission)
Manual transmission owners report clutch pedal sinking to the floorboard without warning, causing loss of clutch engagement. One owner had the clutch replaced but the problem recurred within days. Another owner had six separate clutch replacements by the dealer without resolution.
When: Around 4,300–6,000 miles; recurrence within days of repair
Symptoms owners cite: Clutch pedal travels to floorboard; Loss of clutch engagement; Failure occurs during winter conditions
Repairs/costs cited: Clutch replacement performed by dealer; failure recurred after first repair; one owner required six separate clutch replacements
Recalls/TSBs owners mention: Manufacturer offered no assistance when contacted by at least one owner
Engine Seizure / Sudden Loss of Power
Two owners report sudden engine shutdown or seizure with no warning lights or prior diagnostic codes. One owner's engine was determined to be seized at 88,000 miles immediately after dashboard warning lights appeared; the other lost oil with no oil pressure warning and experienced metal-colored metallic shavings in fresh oil before seizure.
When: 88,000 miles (low-mileage owner who rarely drives); 50,000 miles with no warning light triggered
Symptoms owners cite: Loss of speed and sound of impact while driving; Complete engine shutdown; Engine will not turn over; only clicking sounds; Loss of all power; Vehicle shakes badly before stall; Metal knocking and scraping sounds; Engine oil disappeared despite no visible leaks
Repairs/costs cited: Dealership diagnostic required engine teardown at $1,200 cost; new engine $7,000 or used engine (55k miles) $6,090; owner had received 40-point inspection and oil change 3 weeks prior with no issues detected
Water Intrusion in Convertible Top / Electrical System Failure
Convertible owner reports water intrusion from faulty water bladder (designed to remove water from convertible top in trunk) caused by missing buttons on the convertible top mechanism. The water damage compromised the entire wire loom and fuse box, causing total electrical failure including loss of all brake lights and power. Vehicle became undriveable without warning.
When: Unknown mileage; recurring after initial repair
Symptoms owners cite: Vehicle would not start; Complete electrical system failure; Loss of all brake lights; Loss of all power; Entire wire loom compromised
Repairs/costs cited: Water damage to electrical system not covered by warranty; dealership recommended using a car cover; owner charged for repairs; same problem recurred after initial fix
Transmission Hesitation and Abnormal Shifting (No Stored Codes)
Multiple owners report transmission hesitation, shuddering, and abnormal shifting behavior at low RPMs (1,200–2,000 or 1,500–2,500 range) that occurs across multiple speeds. Notably, dealers are unable to locate diagnostic codes or replicate issues during test drives, yet problems persist or return. Some owners report the issue is dismissed as 'normal' operation despite consistent complaints.
When: 4,000–15,500 miles; increasing frequency over weeks to months
Symptoms owners cite: Transmission hesitation during gradual acceleration; Abnormal shuddering/stuttering at 1,200–2,500 RPMs; RPM hunting (fluctuating between 1,500 and 2,500); Vehicle does not accelerate on demand; Shuddering in both automatic and manual shift modes
Repairs/costs cited: Dealers report 'no error codes found'; computer reprogrammed without success; transmission fluid flushed in one case; dealers claim behavior is normal for 6-speed transmission
Recalls/TSBs owners mention: Manufacturer made aware of some failures but offered no assistance
Sensor / CAN/CAM Sensor Failure
One owner reports engine hesitation and choking during acceleration with fear of stall during gear changes. Five error codes were generated but the specific sensor at fault was not immediately identifiable; dealership technicians performed extended troubleshooting with Chevrolet technical support and proceeded to replace a CAN/CAM sensor despite uncertainty that it was the correct fix.
When: Unknown mileage
Symptoms owners cite: Engine hesitation and choking during acceleration; Feels like car will shut off when shifting gears; Nearly caused highway accidents
Codes mentioned: Five unidentified error codes
Repairs/costs cited: CAN/CAM sensor replacement attempted; part required 3-day wait; repair uncertain; powertrain warranty covered part and labor minus $100 deductible

Having problems with torque converter when trying to accelerate
In may, started to feel a vibration/shimmy of some sort when accelerating in all sorts of speeds. Took vehicle to dealership and they could not duplicate. Vibration/shimmy continued and gradually become more frequent so took vehicle back to dealership in june in which the tech test drove and was able to duplicate the issue. Was told he was not the transmission expert so they had the so called…

It's a documented issue but not catastrophic. 15 complaints have been filed. Repairs average $2,500 and most owners catch it before it causes a breakdown.
At what mileage does the powertrain typically fail?
Across the 13 complaints that reported odometer mileage, most powertrain failures cluster between 7,391 and 34,942 miles, with the median around 8,200. A quarter of owners report trouble before 7,391; a quarter make it past 34,942. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $2,500 for powertrain repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to powertrain?
No active recalls currently cover powertrain issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
