Issue with the oxygen sensor. There is a known issue with the knock sensor sending wrong information to the ECU causing the engine to adjust timing. I've gone through 3 catalytic converters due to this issue. Nissan says they're unaware of the problem and know of no fix. Going through forums, it appears the only way to stop engine from over compensating the timing is to isolate the knock…

What stands out
No new NHTSA powertrain complaint has been filed on this vehicle in over 5 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: Avoid 2010 Nissan Sentras with CVT transmissions unless you can verify recent transmission service or are willing to budget several thousand dollars for replacement. Multiple owners report transmission failure, stalling, and refusal by Nissan to cover even acknowledged defects, plus brake and engine issues that dealers cannot or will not fix.
The 2010 Sentra's powertrain generates consistent failure complaints centered on the CVT transmission. Owners report the transmission stuck in low gear with engine RPM at 5,000–6,000 at highway speeds, erratic shifting, and complete loss of power during normal driving. Several say the transmission locks in Park or neutral and won't engage, leaving them stranded. Nissan extended the CVT warranty to 120,000 miles acknowledging internal defects—specifically coolant contamination—but refuses coverage beyond that limit and charges customers $2,000 toward replacement even under the extended warranty. Transmission replacement costs run $4,200 or more.
Engine stalling without warning occurs at random, sometimes months apart, leaving drivers unable to restart. One owner needed a complete engine replacement after stall-related failure.
The CVT also enters failsafe mode during sustained highway driving, capping speed well below traffic flow and losing power on grades—a serious safety risk. Post-ABS braking creates a separate hazard: after hard stops, the vehicle acts as if brakes remain applied for 15–30 seconds despite pedal release. Nissan reproduces this on multiple Sentras but calls it "working as designed."
Manual transmission SE-R Spec-V owners report knock sensor defects causing repeated catalytic converter failures and engine bucking, with no factory solution available.

Failure modes owners describe
CVT Transmission Stuck in Low Gear / Failure to Upshift
CVT transmission remains in low gear or fails to shift properly, especially after warm-up. Engine runs at very high RPM (5,000–6,000+) at highway speeds. Reports of erratic shifting, slipping sensation, and slight power drag. Some owners report transmission stuck in neutral or unable to shift out of Park. Appears linked to internal mechanical defects and coolant contamination in CVT.
When: Occurs after 10–12 minutes of driving once warmed up; repeats after cool-down periods of 3+ hours. One case at 117,000 miles; others at 70,000–169,630 miles.
Symptoms owners cite: Transmission stuck in low gear despite Drive selection; Excessive RPM at highway speeds (5,000–6,000 RPM at 35 MPH); Erratic shifting and slipping sensation; High engine load and power drag; Transmission locked in Park position (unable to shift); Transmission stuck in neutral position; Loss of motive power during normal driving
Codes mentioned: P0720, P1778
Repairs/costs cited: Full transmission replacement cost cited as $4,200. Nissan extended CVT warranty to 120,000 miles on certain models; however, some owners are out of coverage or denied assistance. Nissan reportedly charges $2,000 customer co-pay for manufacturer-acknowledged defect involving coolant intrusion.
Recalls/TSBs owners mention: Nissan extended CVT warranty to 10 years or 120,000 miles for certain 2010 Sentras. However, Nissan denies coverage for vehicles over mileage limit and refuses to cover defects beyond warranty period despite acknowledging internal mechanical defects and coolant-in-transmission design flaw. Repair diagnosis fee of $500 (4 hours labor at $125/hr) charged before determining warranty eligibility.
Engine Stall Without Warning
Engine shuts off suddenly and unexpectedly while driving at highway speeds, during acceleration from stops, or in parking lots. Vehicle becomes unresponsive after restart attempt or requires tow service. Reports suggest possible electrical or fuel system issue related to a recall.
When: Occurs at random intervals spanning months to years. Events reported at 80,000 miles and at low-speed maneuvers.
Symptoms owners cite: Engine shuts off without warning; Loss of vehicle control after stall; Loss of engine power and inability to accelerate; Dashboard warning lights displayed; Vehicle fails to restart after initial stall; Stalls during acceleration from stop
Repairs/costs cited: One owner reported needing a new engine after stall. Another owner isolated knock sensor with rubber O-ring as community workaround (not factory solution).
Recalls/TSBs owners mention: Nissan claims no recall covers this issue on some vehicles examined. No known fix provided by manufacturer.
CVT Limp Mode / Safe Mode Activation
CVT transmission enters failsafe or 'safe mode' during extended highway driving, limiting vehicle speed to well below posted limits and reducing ability to climb grades. Creates hazardous situation on interstates where traffic flow is disrupted.
When: After 45 minutes of sustained highway driving at 65–70 MPH. Recurs on subsequent trips.
Symptoms owners cite: Transmission enters safe mode due to overheating; Vehicle speed capped at 60 MPH on 70 MPH interstate; Loss of power when attempting to climb hills; Inability to maintain traffic speed; Hazard created by speed differential with traffic
Transmission Engagement Failure / Partial Power
Transmission fails to fully engage or provide normal power delivery, leaving vehicle unable to exceed very low speeds (1–20 MPH) despite engine revving. Occurs after highway driving or during normal acceleration. Engine and restart required to restore function.
When: After 50+ miles of highway driving at 65–70 MPH, or during low-speed maneuvers. One case at 169,630 miles.
Symptoms owners cite: Transmission not fully engaged despite gear selection; Vehicle moves at only 1–5 MPH despite high engine RPM; Inability to accelerate past 20 MPH; Loss of motive power mid-drive; Problem occurs in all gear selections; Engine and transmission restart required to regain function
Repairs/costs cited: Dealer diagnosis identified stepper motor failure in one case. Transmission replacement may be needed.
Post-ABS Brake Engagement Lag
After hard braking that engages ABS, vehicle behaves as if brakes remain applied even after brake pedal is released. Vehicle is immobilized or moves only slowly for 15–30 seconds before resuming normal operation. Occurs after both emergency stops and hard braking during traffic. Nissan acknowledges issue but claims it is 'working as designed' and refuses to address.
When: Immediately after hard braking that triggers ABS; also during heavy traffic braking situations.
Symptoms owners cite: Sensation of brakes remaining applied after release; Vehicle immobilized or moves at crawl speed (1–2 MPH) after brake release; 15–30 second delay before returning to normal function; Shifting between Drive and Reverse does not free the issue; Occurs on multiple different Sentras of same generation
Recalls/TSBs owners mention: Nissan has reproduced this problem on multiple different 2010 Sentras and same-generation model years. Manufacturer states the vehicle is 'working as designed' and will not fix the issue despite safety concern.
Knock Sensor / Engine Timing Issue
Knock sensor sends incorrect information to ECU, causing engine to over-advance timing. Results in repeated catalytic converter failure, engine bucking, and potential catastrophic engine damage. Occurs primarily on manual transmission SE-R Spec-V models. Community workaround involves isolating knock sensor with rubber O-ring, but requires premium fuel to prevent engine damage.
When: Occurs within minutes of starting engine; comes and goes unpredictably. Issue documented in forums since 2008; affects 2007–2012 SE-R Spec-V models.
Symptoms owners cite: Engine bucking and hesitation; Catalytic converter glows bright red; Check Engine light and service warnings; Multiple catalytic converter failures (owner replaced 3); Issue appears and disappears intermittently; Risk of catastrophic engine failure if regular fuel used after sensor isolation
Repairs/costs cited: Owner isolate knock sensor from engine with rubber O-ring gasket; requires premium fuel thereafter. All wiring harnesses, ECU, sensors, and fuel system components replaced without resolving issue.
Recalls/TSBs owners mention: Nissan claims to be unaware of the problem and knows of no factory fix. Issue documented in community forums since 2008 with no manufacturer action.
