Overview
The Chevrolet Camaro returned to the US market in 2010 after a hiatus, spanning two modern generations through 2024. The 5th generation (2010–2015) was built on GM's Zeta platform and emphasized classic muscle car proportions with modern performance. The 6th generation (2016–2024) shifted to the lighter Alpha platform, improving handling and offering a broader range of powertrains from a turbocharged 4-cylinder to the supercharged LT4 V8 found in the ZL1. Common issues across generations include evaporative emission system leaks, catalytic converter efficiency codes, throttle body concerns, transmission shifting faults, and—particularly in the 5th gen—visibility and interior quality complaints. The 6th gen introduced more electronically complex systems, adding potential for communication bus and throttle/electronic throttle control faults.
Quick Summary
By Generation
Available Engines
Common OBD2 Codes
| Code | Frequency | Notes |
|---|---|---|
| P0442 | Very Common | Small EVAP leak — most common code on 5th gen. Frequently caused by a loose or degraded fuel cap, cracked EVAP hose near the charcoal canister, or a faulty purge solenoid. GM issued TSB #11-06-04-006 addressing EVAP purge valve noise and leak conditions. |
| P0455 | Very Common | Large EVAP leak detected. Often traced to the fuel cap, EVAP vent valve, or canister hoses. Can also appear after fuel fill-up if cap is not tightened properly. |
| P0420 | Very Common | Catalyst efficiency below threshold — Bank 1. A known issue on higher-mileage 5th gen V6 and V8 engines. May be caused by a deteriorating rear catalytic converter, an exhaust leak upstream, or faulty downstream O2 sensor (P0136/P0137 often accompanies). Note: code P0420 itself is valid; inspect upstream at P0133. |
| P0430 | Very Common | Catalyst efficiency below threshold — Bank 2 (V8 only). Same root causes as P0420 on the opposite bank. Common on LS3/L99 engines with higher mileage. |
| P0171 | Common | System too lean, Bank 1. On the V6 LLT/LFX, often caused by a cracked intake manifold gasket or vacuum leak near the throttle body. On V8 engines can be caused by a faulty MAF sensor or fuel pressure drop. |
| P0172 | Common | System too rich, Bank 1. On V8 engines sometimes related to a stuck-open fuel injector or faulty O2 sensor. Also appears after extended idling with a dirty MAF. |
| P0300 | Common | Random/multiple cylinder misfire. On 5th gen V8s often related to carbon buildup on injectors or faulty coil-on-plug ignition coils. Check related P0301–P0308 for specific cylinder identification. |
| P0507 | Common | Idle air control system — RPM too high. Frequently caused by a dirty or failing electronic throttle body on the V6. GM TSB #10-06-04-012 covers idle quality concerns on the LLT V6. |
| P0128 | Common | Coolant temperature below thermostat regulating temperature. A very common fault caused by a failed-open thermostat; more prevalent in colder climates. Replacement thermostat is inexpensive and straightforward. |
| P0741 | Common | Torque converter clutch circuit performance (automatic transmissions). Seen on 6L80 and 6L50 equipped Camaros; may indicate TCC solenoid wear or fluid degradation. Often accompanied by a shudder at light throttle cruise. |
| P0335 | Occasional | Crankshaft position sensor circuit range/performance. Reported on higher-mileage V8 engines; can cause stalling or no-start conditions. Sensor replacement typically resolves the fault. |
| P0606 | Occasional | ECM/PCM processor fault. Occasionally reported on 5th gen — usually points to a PCM software issue or internal failure. GM may have reprogramming fixes via TIS. Verify grounds before replacing PCM. |
Known Problems
The 3.6L LLT and LFX V6 engines are prone to carbon buildup on the throttle body bore and plate, leading to rough idle, hesitation, and high idle RPM faults (P0507). Direct-injection engines do not benefit from port fuel washing the intake, compounding the issue. Cleaning the throttle body every 30,000–50,000 miles is recommended.
Typical mileage: 40,000–80,000
Shop parts for this repairSmall and large EVAP leak codes are the most frequently reported Check Engine issues on 5th gen Camaros. The evaporative emission purge solenoid (mounted on the intake manifold) is a common failure point, as are the EVAP hoses near the charcoal canister under the hood. The fuel cap seal also degrades over time.
Typical mileage: 30,000–100,000
Shop parts for this repairHigh-mileage 5th gen Camaros, particularly the V8 models, develop catalyst efficiency faults on one or both banks. The factory converters are adequate but not long-lived under hard driving. Exhaust leaks upstream can accelerate catalyst failure and should be ruled out before replacement.
Typical mileage: 80,000–130,000
Shop parts for this repairA widely reported design complaint on 5th gen Camaros is the very limited rear visibility due to thick C-pillars and a narrow rear window. While not an OBD2 fault, this led to real-world safety concerns and contributed to GM offering an optional rear-view camera starting in 2012. Owners are strongly advised to use the backup camera and check blind spots carefully.
Typical mileage: Any
Shop parts for this repairThe 6L80 6-speed automatic used with V8 engines can develop a light throttle shudder between 45–55 mph caused by torque converter clutch (TCC) slip. GM released updated transmission fluid and software calibrations addressing the issue. Many owners resolve it with a Dexron VI fluid change and a PCM reflash.
Typical mileage: 30,000–70,000
Shop parts for this repairThe LS3 and L99 V8 engines can experience misfires due to failing individual coil-on-plug ignition coils or worn spark plugs. AC Delco iridium plugs should be replaced around 60,000 miles. Coils are inexpensive and are often replaced in sets when one fails.
Typical mileage: 60,000–100,000
Shop parts for this repairThe engine coolant thermostat on 5th gen Camaros frequently fails in the open position, preventing the engine from reaching proper operating temperature. This reduces fuel economy, increases emissions, and triggers P0128. Thermostat replacement is inexpensive and a common maintenance item by 80,000 miles.
Typical mileage: 50,000–90,000
Recalls
Power steering assist loss — the electric power steering (EPS) module could lose assist due to a software error, requiring greater steering effort. GM issued a dealer software update. Affected 2010 Camaro V6 and V8 models.
Ignition switch recall (related to broader GM ignition switch crisis). Certain 2010–2014 Camaros were included in recall actions requiring ignition switch replacement to prevent inadvertent key rotation to the OFF position, which could disable the airbag system.
Hood latch secondary catch — the secondary hood latch could be inadvertently released during normal driving, potentially allowing the hood to open while in motion. Dealers inspected and replaced the secondary latch assembly as needed.
Rear suspension lateral link — on certain 2010–2013 Camaro vehicles, the rear suspension lateral link could fracture under hard cornering or repeated stress, affecting handling and potentially causing loss of control. Replacement of affected components was performed by dealers.

Common OBD2 Codes
| Code | Frequency | Notes |
|---|---|---|
| P0442 | Very Common | Small EVAP leak — remains the most common MIL-on code across the 6th gen. The 2.0T and V6 are especially prone due to tight engine bay packaging of EVAP hoses. Inspect purge solenoid valve and fuel cap seal first. |
| P0455 | Very Common | Large EVAP leak. Commonly caused by the fuel cap or a cracked EVAP vent hose at the charcoal canister. The 6th gen Alpha platform moved some EVAP components to less accessible locations. |
| P0171 | Very Common | System too lean, Bank 1. On the 2.0T LTG engine, lean codes can result from a faulty MAF sensor, a cracked charge air cooler (CAC) pipe or intercooler hose, or a leaking turbo inlet hose — all of which allow unmetered air post-MAF. On V6/V8 models, vacuum leaks are the typical cause. |
| P0300 | Common | Random misfire. The 2.0T LTG engine has had documented misfires related to carbon buildup on intake valves (direct injection with no port wash). The LT1 V8 can exhibit misfires from worn AFM (Active Fuel Management) lifters. |
| P0420 | Common | Catalyst efficiency, Bank 1. More prevalent at higher mileages. On ZL1 models, aggressive driving accelerates catalyst degradation. Often accompanied by faint sulfur smell. |
| P2135 | Common | Throttle/pedal position sensor — throttle/pedal position correlation. Seen on 2.0T and V6 models; can put the vehicle into a reduced power mode (limp mode). Throttle body cleaning or replacement typically resolves. Related to electronic throttle control system. |
| P0101 | Common | Mass air flow sensor range/performance. On the 2.0T, turbo boost system air leaks downstream of the MAF can cause this code. On naturally aspirated models, a dirty or failing MAF element is the typical cause. |
| P0741 | Common | Torque converter clutch performance. Applies to 8-speed (8L45/8L90) automatic transmissions used in 6th gen. TCC shudder at light cruise is a known complaint; GM released updated transmission fluid (Dexron HP) and TCM calibrations. |
| P0562 | Occasional | System voltage low. Occasionally reported on 6th gen Camaros with aging batteries or high electrical loads; the 2.0T Stop/Start system places increased demand on the battery. Replace with an AGM battery when applicable. |
| U0100 | Occasional | Lost communication with ECM/PCM. Seen on some 6th gen vehicles, often after battery disconnect or during low-voltage conditions. Check all ground straps and battery terminal connections before replacing modules. |
| P2096 | Occasional | Post-catalyst fuel trim system too lean, Bank 1. Can indicate a genuine exhaust lean condition or a deteriorating downstream O2 sensor. Verify with live O2 sensor data. |
| P0304 | Occasional | Cylinder 4 misfire. On the LT1 V8 with AFM (Active Fuel Management), the deactivation lifters on cylinders 1, 4, 6, and 7 are prone to premature wear. A collapsed lifter on cylinder 4 is a well-documented failure. Note: GM released the DFM-delete/AFM-disable option on later 6th gen vehicles. |
Known Problems
The 6.2L LT1 V8's Active Fuel Management system uses switchable deactivation lifters on cylinders 1, 4, 6, and 7. These lifters are prone to premature failure — typically a collapsed lifter — resulting in loud ticking, misfires, and metal debris in the oil. The fix requires a full AFM lifter replacement and often a camshaft replacement as well. Many owners install AFM disablers or reprogram the ECU to prevent deactivation. GM quietly acknowledged the issue and transitioned late production to Dynamic Fuel Management (DFM) with revised hardware.
Typical mileage: 60,000–120,000
Shop parts for this repairThe 2.0L LTG turbocharged engine is prone to cracked or loose charge air cooler (CAC/intercooler) inlet and outlet hoses, particularly at the hard plastic pipe connections. These leaks allow unmetered air to enter the intake post-MAF, causing lean codes, boost loss, and hesitation. The plastic pipes can crack from heat cycling; aftermarket silicone hose kits are a popular upgrade.
Typical mileage: 30,000–80,000
Shop parts for this repairThe 8-speed automatic transmissions used in 6th gen Camaros can develop a noticeable shudder or vibration at light throttle between 25–50 mph due to torque converter clutch slip. GM has released multiple transmission control module (TCM) software updates and changed the recommended fluid to Dexron HP. In some cases, the TCC solenoid or torque converter requires physical replacement.
Typical mileage: 20,000–60,000
Shop parts for this repairDirect-injection engines, including the 2.0T LTG and 3.6L LGX, accumulate carbon deposits on the throttle body plate and bore over time. This can cause a rough idle, hesitation, P2135 throttle position correlation errors, and in some cases the vehicle enters a reduced power mode. Periodic throttle body cleaning every 30,000–40,000 miles is recommended. If the electronic throttle body fails entirely, replacement is required.
Typical mileage: 30,000–70,000
Shop parts for this repairAcross all 6th gen engine variants, EVAP leak codes are the most common MIL-on complaints. The EVAP purge solenoid valve (located on the intake manifold) is a frequent failure point and costs $30–$80 to replace. Hose routing in the tight Alpha platform engine bay can cause chafing and cracking. The fuel cap seal also degrades and should be inspected annually.
Typical mileage: 25,000–100,000
Shop parts for this repairMany 6th gen Camaro owners report intermittent freezing, rebooting, and audio dropout from the Chevrolet MyLink (2016–2018) and Infotainment 3 (2019–2024) systems. These are software-based issues and GM has issued multiple over-the-air or dealer-installed software updates. Some U-code communication faults (e.g., U0155 lost communication with instrument panel cluster) can originate from infotainment system faults.
Typical mileage: Any
Shop parts for this repairAs a direct-injection engine, the 2.0L LTG has no port fuel spray to clean the intake valves. Carbon deposits accumulate over time, reducing airflow and causing hesitation, rough idle, and misfires. A walnut blasting or chemical intake cleaning procedure is recommended around 60,000–80,000 miles. Some owners add an oil catch can to reduce the rate of buildup.
Typical mileage: 60,000–100,000
Shop parts for this repairThe 6th gen ZL1's LT4 supercharger can develop oil leaks from the front snout seal or rear shaft seal, especially on vehicles driven hard or used for track days. Supercharger oil seeps onto the accessory belt and other components. A supercharger rebuild or replacement seal kit is the solution; this is a known limitation of the Eaton TVS R2300 supercharger on high-heat cycles.
Typical mileage: 40,000–80,000 or after heavy track use
Shop parts for this repairRecalls
Seat back strength — on certain 2016 Camaro models, the front seat back frame welds may not meet federal safety standards for rear-impact seat back strength, potentially increasing injury risk in a rear collision. Dealers inspected and replaced affected seat back frames.
Side curtain airbag deployment — on certain 2016–2018 Camaro vehicles, the side curtain airbag inflator could deploy improperly during a rollover event, potentially failing to provide intended protection. Dealers replaced the side curtain airbag inflator assemblies.
Brake booster vacuum hose — on certain 2019–2020 Camaro V8 SS models, a brake booster vacuum hose could crack or separate, reducing brake assist and increasing stopping distances. Dealers inspected and replaced affected vacuum hoses at no charge.
Rearview camera image delay — on certain 2022 Camaro models, the rearview camera image could be delayed or fail to display when shifted into reverse, reducing rearward visibility and not complying with FMVSS 111. A software update was provided to correct camera initialization timing.
Forward collision alert false activation — certain 2022–2023 Camaro models equipped with Forward Collision Alert could generate unintended audible and visual warnings in the absence of an actual forward collision hazard, potentially distracting the driver. A software update was issued to recalibrate the system.
