The 2019 Sentra continues Nissan's problematic CVT reliability issues, but the naturally-aspirated 1.8L engine is mechanically simple and durable when maintained. The 1.6T turbo variant is rare but carries higher risk of internal engine problems.
Symptoms: shuddering or vibration during acceleration, especially 15-40 mph, delayed engagement when shifting to Drive or Reverse, transmission overheating warnings, whining or grinding noises during acceleration, complete loss of forward movement
Fix: Most fail due to valve body contamination or belt wear. Early cases may respond to fluid flush with genuine Nissan NS-3 fluid (2 hours labor), but most require CVT replacement or rebuild. Full replacement is 8-12 hours labor depending on accessibility.
Estimated cost: $3,500-6,000
Transmission Oil Cooler Leaks
Occasional · medium severity
Typical onset: 50,000-90,000 mi
Symptoms: CVT fluid puddles under engine bay, transmission running hotter than normal, burnt smell from transmission, low CVT fluid level on dipstick
Fix: External oil cooler lines and cooler itself develop leaks at fittings and seams. Replacement requires draining CVT and dropping cooler assembly. 3-4 hours labor including refill and burp procedure.
Symptoms: heavy blue smoke on startup or acceleration, severe misfires and check engine light, loss of compression in one or more cylinders, metal shavings in oil, catastrophic knocking noise
Fix: The 1.6T can suffer piston ringland cracks, bearing failure, or oil consumption issues under stress. Minor cases need piston/ring replacement (20 hours), severe cases require short block or complete engine replacement (25-35 hours). Most cost-effective solution is used engine swap.
Estimated cost: $4,500-8,000
Transmission Mount Failure
Common · low severity
Typical onset: 70,000-110,000 mi
Symptoms: clunking when shifting into Drive or Reverse, excessive engine movement visible when accelerating, vibration through cabin at idle, knocking from engine bay over bumps
Fix: Upper transmission mount (torque strut) wears and tears, allowing excessive powertrain movement. Simple replacement takes 1.5-2 hours. Use OEM or quality aftermarket; cheap mounts fail quickly.
Estimated cost: $250-450
Brake Light Switch Failure (Recall 20V-066)
Occasional · medium severity
Symptoms: brake lights stay on continuously, cruise control won't engage, push-button start won't work even with brake pedal pressed, check engine light with P0504 code
Fix: Faulty brake light switch prevents starting or causes lights to stick on, draining battery. Covered under recall, dealer replaces free of charge (0.5 hours). If out of warranty at indie shop, 0.3-0.5 hours labor.
Estimated cost: $0-150
Backup Camera Failure (Recall 19V-121)
Occasional · low severity
Symptoms: backup camera shows no image or distorted image, blank screen when shifting to Reverse, intermittent camera function
Fix: Camera or display unit fails, usually requires camera replacement. Covered under recall at dealer at no charge (1 hour). Post-recall, indie shop replacement is 1-1.5 hours.
Estimated cost: $0-400
Fuel Filter Clogging (Premature)
Occasional · medium severity
Typical onset: 50,000-90,000 mi
Symptoms: rough idle and hesitation during acceleration, engine stalling especially when fuel tank is low, difficulty starting after sitting, check engine light with fuel trim codes
Fix: In-tank fuel pump assembly filter clogs earlier than expected, especially with lower-quality fuel. Requires dropping fuel tank and replacing pump module. 3-4 hours labor total.
Estimated cost: $500-900
Owner tips
CVT fluid exchanges every 30,000 miles with genuine Nissan NS-3 fluid can extend transmission life—do NOT let shops use universal CVT fluid
Check CVT fluid level monthly; these run very low capacity and small leaks cause rapid failure
Avoid the 1.6L Turbo if buying used unless full service history shows conservative driving and religious maintenance
The 1.8L MR18DE engine is dead-reliable with oil changes every 5,000 miles; ignore 10,000-mile interval in manual
Address transmission shudder immediately with fluid service; waiting leads to total CVT failure
Buy the 1.8L only, budget $1,500 for eventual CVT repairs, and plan to keep CVT fluid fresh—otherwise solid transportation if you avoid the turbo engine.

Nissan North America, Inc. (Nissan) is recalling certain 2018-2019 Nissan Altima, Armada, Frontier, Kicks, Leaf, Maxima, Murano, NV, NV200, Pathfinder, Rogue, Rogue Sport, Sentra, Titan, Titan Diesel, Versa Note and Versa Sedan vehicles, as well as Infiniti Q50, Q60, QX30 and QX80 vehicles. Additionally included are 2019 Nissan GT-R and Taxi and Infiniti QX50, QX60, Q70, Q70L vehicles. The back-up camera and display settings can be adjusted such that the rear view image is no longer visible and the system will retain that setting the next time the vehicle is placed in reverse. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rear Visibility."
Consequence: The lack of an image in the back-up camera display increases the risk of a crash.
Remedy: Nissan will notify owners in phases, having dealers update the back-up camera settings software, free of charge. The recall began November 11, 2019 and all affected VINs should be activated. Owners may contact Nissan customer service at 1-800-867-7669 or INFINITI customer service at 1-800-662-6200.
