2022 Hyundai Santa Fe cruise control problems

The failure pattern owners describe
Buyer takeaway: Multiple 2022 Santa Fe owners report fuel injector failures, transmission shift hesitations, and advanced cruise control/ADAS disengagement—sometimes occurring repeatedly within warranty periods. Hyundai authorizes repairs only after failure, not preventively, despite documented recurring patterns.
Owners describe a cluster of related powertrain and safety system failures. Fuel injector failures recur, causing loss of power, jerking, and grinding noise; some vehicles fail twice within 5,000 miles of prior repair. Hyundai approves replacement only after failure occurs, not preventively, despite owners confirming the issue is common across their 4-cylinder engine lineup. Transmission hesitation and rough shifting began in fall 2024 for some owners; a software update provided partial relief in Smart Drive Mode only, and a recall (Campaign #22V746000) addresses similar symptoms.
Smart cruise control and forward collision avoidance systems disengage unexpectedly at highway speed, triggering check-engine and system-error warnings. One vehicle's cruise control applied excessive brake pressure on downhill grades, destroying rotors. Owners cite hundreds of similar complaints documented online and note Hyundai issued a technical bulletin for another model with the same issue.
Additional failures include unexpected acceleration on gear shifts, stalling at lights and while driving, vehicle shifting itself to Neutral, and one incident of sudden uncontrolled deceleration from 67 mph to near-stop in under two minutes. No warning lights preceded most failures. Dealerships have struggled to diagnose some conditions or declined to authorize preventive repairs.
Failure modes owners describe
Fuel Injector Failure
Multiple fuel injectors fail, causing loss of power, jerking, shaking, bucking, and grinding noise. Some vehicles experience two or more injector failures within the warranty period. Owners report Hyundai will only authorize replacement after failure, not preventively despite the recurring pattern.
When: Various: around 2,500 miles in one case; within 5K miles of prior repair in another; no specific timing in others
Symptoms owners cite: Loss of power when accelerating; Engine jerking and bucking; Grinding noise; Difficulty maintaining speed on highway; Check engine light; No warning before failure
Codes mentioned: Check Engine Light
Repairs/costs cited: Two fuel injectors replaced in one case; dealership refused to replace other two under warranty. Front radar module replaced under warranty in cruise-control-related case. Multiple injector replacements required for some vehicles.
Recalls/TSBs owners mention: Warranty only covers repair after individual failure, not preventive replacement. Hyundai stated they cannot authorize work until injectors fail.
Transmission / Shift Hesitation
Vehicle hesitates or fails to shift smoothly when accelerating; RPMs rise without corresponding power delivery. Software updates provide partial temporary relief. Owners cite Recall #22V746000 (Campaign 236) as addressing similar transmission issues.
When: Fall 2024 onward; recurring on multiple occasions over several months
Symptoms owners cite: No shift when accelerating on gas pedal; RPMs spike to 5,000 with no power delivery; Jerking during acceleration and stopping; Smoother shifting only in Smart Drive Mode after software update; Unexpected loss of power during traffic entry
Repairs/costs cited: Software update performed at dealership on 11/14/24 with partial improvement. Vehicle towed multiple times.
Recalls/TSBs owners mention: Hyundai transmission recall #22V746000 (Campaign 236) exists for similar symptoms; dealership performed software update with limited benefit
Smart Cruise Control and ADAS Disengagement / Malfunction
Adaptive cruise control and forward collision avoidance features disengage unexpectedly during operation, disabling safety systems. One vehicle's cruise control rode brakes excessively on downhill sections, destroying rotors. Another experienced radar module failure. Owners report hundreds of similar complaints documented online.
When: Various; one rotor failure at approximately 2,500 miles
Symptoms owners cite: Unexpected disengagement of smart cruise control while driving at highway speed; Front collision avoidance system error messages; Radar blocked warnings; Excessive brake application on downhill grades while cruise engaged; Check Forward Safety System warning; Advanced cruise control parameters not met warnings
Codes mentioned: C162078, Check Forward Safety System
Repairs/costs cited: Front radar module replaced and reprogrammed under warranty. Rotors destroyed; dealer only turned them rather than addressing root cause of excessive brake engagement.
Recalls/TSBs owners mention: Hyundai published a technical bulletin for another model with similar ADAS/cruise control disengagement issue. Front radar module replaced under warranty in at least one case.
Unexpected Acceleration
Vehicle experiences unexpected surge in acceleration when initially pressing gas pedal after shifting from Park to Drive, even with light throttle input. Occurs at low mileage and with no prior indication.
When: At approximately 13,000 miles
Symptoms owners cite: Unexpected additional acceleration with light gas pedal input after P-to-D shift; No warning lights or alerts
Stalling and Loss of Drive
Vehicle stalls at lights or while driving. Car occasionally puts itself into Neutral or shuts off completely without warning. Outside mechanic scan revealed a general fault code.
When: Unknown; vehicle appears to have multiple incidents over time
Symptoms owners cite: Stalling at traffic lights; Stalling while driving; Vehicle shifts itself into Neutral; Vehicle shuts off completely; No warning lights; Acceleration problems present alongside stalling
Codes mentioned: General fault code (unspecified, found by outside mechanic)
Repairs/costs cited: Outside mechanic performed scan and found a general code indicating a fault present.
Recalls/TSBs owners mention: Hyundai not responding to follow-up per owner. Prior complaint filed with reference number 11494975 but owner unable to retrieve information.
Uncontrolled Deceleration
Vehicle decelerates abruptly from highway speed to near-stop in less than two minutes with audible warning sounds (ringing). Occurred at least twice; dealership unable to reproduce the issue.
When: Unknown; incidents occurred within recent period prior to complaint filing
Symptoms owners cite: Three ringing sounds preceding deceleration; Rapid deceleration from 67 mph to 0 in less than two minutes; No ability for dealership to reproduce
Repairs/costs cited: Dealership unable to diagnose or recreate the condition.

Common questions
How serious is the cruise control problem on the 2022 Hyundai Santa Fe?

At what mileage does the cruise control typically fail?
Based on the 10 complaints filed, cruise control issues most often appear around 2,500 miles. Some report problems earlier; some make it well past 150,000 with no symptoms. Maintenance habits matter — vehicles that received timely fluid services and were not regularly overworked tend to last longer.
What does it cost to fix?
Independent shops typically charge around $600 for cruise control repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to cruise control?
No active recalls currently cover cruise control issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
