The most critical issue, CVT Transmission Failure/Shudder, typically costs $300-$5,000 to repair. Au7o provides step-by-step DIY maintenance guides that can help reduce repair costs.
The CVT transmission is known for reliability issues including shuddering, jerking, and complete failure. Nissan extended the CVT warranty on some model years to 10 years/120,000 miles due to widespread problems. High-mileage CVTs are particularly at risk. Repairs typically run $300-$5,000. Severity: high.
Nissan issued a recall for fuel pump issues that can cause engine stalling or failure to start. The fuel pump impeller may deform, causing fuel delivery problems. This affects multiple Nissan models. Repairs typically run $0-$0. Severity: high.
Nissan Altima models built with the 3-cylinder 1.5L (KR15DDT) or 4-cylinder 2.0L (KR20DDET) variable-compression turbo (VC-Turbo) engine can suffer a manufacturing defect in the engine's bearings (main bearing and the A-, C-, and L-link bearings that are unique to the variable-co… Repairs typically run $0-$9,000. Severity: high.
Altimas equipped with Nissan's standard Forward Emergency Braking / Automatic Emergency Braking (part of the Safety Shield 360 / Forward Collision suite) are widely reported to activate suddenly when no collision is imminent — so-called 'phantom braking.' Owners and NHTSA complai… Repairs typically run $0-$600. Severity: high.
The A/C compressor can fail, particularly on vehicles in hot climates. When the compressor fails internally, it can contaminate the A/C system with debris. Clutch failure is also common. Repairs typically run $500-$1,500. Severity: medium.
The 2.5L PR25DD four-cylinder used in 2019+ Altimas is direct-injection only, so fuel never washes the back of the intake valves. Over time carbon/soot accumulates on the intake valves and on the intake-manifold runner control flaps, causing rough idle, hesitation, reduced power,… Repairs typically run $400-$1,200. Severity: medium.
P0420 (catalyst system efficiency below threshold) is one of the most common check-engine codes on the 2.5L Altima. The integrated exhaust-manifold/catalyst on these cars loses efficiency as the substrate degrades, the downstream oxygen sensor begins tracking the upstream sensor,… Repairs typically run $300-$1,850. Severity: medium.
Some Altima owners experience unexplained battery drain, resulting in a dead battery after sitting for a few days. Various electronic modules not going to sleep properly can cause excessive draw. The Intelligent Key system may also be a factor. Repairs typically run $100-$500. Severity: low.
The infotainment system can experience freezing, lag, and connectivity issues. Bluetooth pairing problems and CarPlay/Android Auto disconnections are common. The touchscreen may become unresponsive. Repairs typically run $0-$800. Severity: low.
Owners report widespread clearcoat/paint peeling and flaking, with the hood and roof typically the worst-affected horizontal panels, sometimes coming off in large jagged strips.

After a loose/failed gas cap, the most common cause of EVAP leak codes (P0455 large leak, P0456 very small leak) on the Altima is a failed EVAP canister vent control valve mounted near the charcoal canister at the rear of the vehicle. The valve seal sticks or fails to seal, so th… Repairs typically run $60-$250. Severity: low.
