Owners of the 2021 Nissan Rogue consistently report engine troubles, many documented before 140,000 miles. The most serious: coolant mixes with oil due to blown head gaskets, forcing dealers to recommend full engine replacement at costs ranging $6,231 to $10,000. Multiple owners describe the vehicle overheating, consuming coolant rapidly without visible external leaks, and emitting white smoke from the exhaust or dipstick area—all hallmarks of internal coolant breaches.
Beyond head gaskets, owners encounter a pattern of vague malfunctions: check engine lights illuminate with messages like "Engine Malfunction" or "Engine Power Reduced," yet mechanics and dealers run diagnostics and find no fault codes, leaving the vehicle unrepaired. Several owners report the engine stalling on highways or losing power during acceleration, requiring the driver to pull over, restart, and continue. One complaint describes the transmission failing to shift properly until restarted, while another owner detailed the vehicle not starting for 30 minutes after parking.
Dealers appear unable or unwilling to diagnose root causes. When they do attempt repairs—replacing thermostats, brake pads, air filters, EGR valves—the failure persists or returns within days. Warranty denials are common, even at mileages under 130,000 miles. One owner noted the loaner vehicle Nissan provided—a 2023 Rogue—exhibited identical malfunction errors, suggesting the issues may not be isolated.
Failure modes owners describe
Blown/Failed Head Gasket with Coolant Mixing into Oil
Coolant leaks internally past the head gasket into the oil pan, causing emulsified oil, engine overheating, rough running, and white smoke from exhaust. Owners report being told a full engine replacement is needed.
When: 100,000–140,000 miles reported; one case at 127,000 miles
Symptoms owners cite: Excessive coolant consumption; Coolant mixed with oil on dipstick; Engine overheating while driving; White smoke from exhaust or dipstick area; Rough/difficult engine start; Engine knock or rattle; Loss of cabin heat; Engine runs rough
Codes mentioned: No specific codes reported; diagnosed mechanically as blown head gasket
Repairs/costs cited: New engine required; costs cited $6,231 for used engine (30k miles) in one complaint; dealers refused repair under expired warranty in another
Recalls/TSBs owners mention: No recalls or TSBs mentioned; one complaint references NHTSA Campaign 25V437000 but reports VIN not included in recall coverage
EGR Cooler Issues (Internal Coolant Leak)
EGR cooler develops internal leaks allowing coolant to enter the engine block. Owners report low coolant levels without visible external leaks and failed heat operation after coolant service.
When: 102,000 miles in one case; occurs after perceived coolant service
Symptoms owners cite: Low coolant level with no visible leak; Vehicle bucking while changing gear; Heat becomes inoperative; Possible engagement of safety system due to low coolant
Codes mentioned: Check engine light illuminated (narrative #6)
Repairs/costs cited: EGR cooler replacement recommended but parts on back order; vehicle not repaired
Recalls/TSBs owners mention: No manufacturer response documented for this failure mode
Low Coolant with No External Leak
Engine coolant level drops rapidly despite no visible external leaks, forcing owners to repeatedly refill reservoirs. Mechanics and dealers cannot locate leak source, and thermostat replacement does not resolve the issue.
When: 100,000–112,000 miles reported; one case at 90,000 miles with loaner vehicle also affected
Symptoms owners cite: Temperature gauge indicates overheating; Coolant level low after short drives (4 miles in one case); No warning light illuminated in some cases; Issue persists across multiple vehicles (loaner Rogue also had same problem)
Codes mentioned: Check engine light (in some cases)
Repairs/costs cited: Thermostat replaced at 100,000 miles without resolving issue; mechanics and dealers unable to find cause or duplicate failure
Recalls/TSBs owners mention: One owner advised to contact NHTSA Hotline; another directed to diagnostic testing; no recall or TSB mentioned
Engine Malfunction and Power Reduction Messages
Check engine light illuminates and dashboard messages 'Engine Malfunction,' 'Engine Power Reduced,' or 'Malfunction Error' appear during normal driving. Vehicle becomes difficult to start and may require jump-starting.
When: 58,344 miles; 90,000 miles; occurs across multiple mileage ranges
Symptoms owners cite: Check engine light illuminated; 'Engine Malfunction' message displayed; 'Engine Power Reduced' message displayed; 'Malfunction Error' message displayed; Difficult to start; requires jump-start; Failure recurs after multiple dealer visits and repairs
Codes mentioned: No diagnostic trouble codes retrieved by dealers despite multiple visits
Repairs/costs cited: Two dealers performed unrelated repairs (brake pads, air filters, oil changes, coolant replacement) but failure persisted; vehicle never successfully diagnosed or repaired
Recalls/TSBs owners mention: One case confirmed no recalls on VIN; another referenced NHTSA Campaign 25V437000 but VIN not included; no recall coverage provided
Engine Stalling During Drive
Engine unexpectedly shuts down while vehicle is in motion, requiring restart or towing. Multiple episodes reported across different speeds and conditions, including highway driving.
When: 67,000 miles; 121,000 miles; recurring issue over years in some cases
Symptoms owners cite: Vehicle stalls and shuts off while driving at 30–65 MPH; Multiple warning lights illuminate before stall; Vehicle initially restarts but failure recurs; Vehicle fails to restart after stalling; Fuel gauge misreads (fuel pump system failure noted in one case); Repeated occurrences despite prior repairs
Codes mentioned: Unknown/incomplete diagnosis in some cases
Repairs/costs cited: Nissan dealership cited fuel pump system failure in one case; another was in process of towing to dealer for diagnostic when complaint filed; no repairs completed
Recalls/TSBs owners mention: One contact unable to reach manufacturer by phone; no recall coverage confirmed; one case linked by owner to NHTSA Campaign 25V437000 but VIN not in recall
Loss of Motive Power and Unintended Deceleration
Engine loses power or throttle response during driving, causing vehicle to slow or stop despite accelerator input. In one case, engine also overheated during the event.
When: 100,000 miles; 121,000 miles
Symptoms owners cite: Vehicle loses motive power and decelerates unintentionally; Accelerator pedal depressed but vehicle does not move; Vehicle jerks while changing gear; Engine overheats during power loss; Vehicle unintendedly decelerates to 15 MPH at 45 MPH driving speed; Check engine light illuminated
Codes mentioned: Check engine light present; no specific codes documented
Repairs/costs cited: Diagnosed as premature engine failure in one case; vehicle not repaired due to lack of warranty coverage
