The failure pattern owners describe
Owners of 2022 Santa Cruz vehicles report fuel injector failures as the most common engine issue, with symptoms including rough cold starts, cylinder misfires (P0301, P23F5F0), check engine lights, shaking, and loss of power. Replacements of 2–6 injectors occur under warranty, but repairs sometimes fail to resolve the fault on first attempt. Diagnosis and repair timelines stretch to months, with dealers unable to replicate intermittent faults consistently and requiring engine stall-outs to happen in their presence before Hyundai corporate approves repairs. One owner replaced injectors, only to have the same code return within a day; final resolution took multiple service visits over four months.
Engine stutter and complete stalls also appear frequently, sometimes with limp mode activation, occurring within the first 500–1,800 miles. One owner experienced four engine shutdowns in less than 1,800 miles. Transmission issues—loss of power, shift failure, and one complete transmission replacement at 20K miles—are reported alongside engine troubles. Engine knock on cold start after extended driving is noted by two owners of separate vehicles, suggesting a pattern.
Other engine-related failures include a loose oil dipstick seal that sprayed oil throughout the engine bay, and radiator punctures that dealers classify as road damage rather than defects. Owners describe dealer delays for scheduling, lack of loaner vehicles, and refusals to cover out-of-pocket costs (towing, hotels, rentals) until repairs are complete, sometimes stretching service delays indefinitely.
Failure modes owners describe
Fuel Injector Failures
Multiple fuel injectors fail, causing rough cold starts, misfires, and check engine lights. Owners report replacing 2-6 injectors under warranty. The issue persists intermittently after repair on some vehicles, with dealers unable to consistently replicate the fault or secure manufacturer approval for additional diagnostics.
When: 29K miles (complaint #1), under 800 miles (complaint #4), low mileage across fleet per complaint #5
Symptoms owners cite: Rough cold starts; Cylinder misfire (P0301, P23F5F0 codes); Check engine light; Engine shaking and shuddering; Loss of power during acceleration; Inability to accelerate past 25 mph
Codes mentioned: P0301, P23F5F0
Repairs/costs cited: Owners report replacement of 2–6 fuel injectors (high-pressure and low-pressure). One owner waited months and made 5 dealer trips; another repair failed to resolve the DTC on first attempt.
Recalls/TSBs owners mention: Repairs covered under warranty. However, Hyundai corporate required issue replication before approving repairs, delaying diagnosis and repairs by weeks to months. One owner (#3) reported Hyundai would not reimburse towing, hotel, Uber, or rental costs until full repair completion.
Oil Dipstick Seal Failure
Oil dipstick O-ring seal fails, causing oil to spray throughout the engine bay and undercarriage during normal operation. Dealer attributed failure to a defective dipstick without taking responsibility for the oil contamination or unsafe condition.
When: At 26K miles; discovered after routine oil change and tire rotation
Symptoms owners cite: Burning oil smell; Oil spray throughout engine compartment, undercarriage, wheel wells, brake calipers
Repairs/costs cited: Dealer cleaned engine compartment but did not resolve underlying dipstick seal defect. Owner traded vehicle in due to safety concerns and loss of manufacturer support, resulting in loss of favorable financing (2.74% interest) and equity.
Recalls/TSBs owners mention: Hyundai customer service denied responsibility, instructed owner to drive vehicle despite oil contamination, refused to escalate complaint, and hung up on owner. No recall or TSB mentioned.
Engine Knock on Cold Start
Engine produces audible knock noise on first start-up the day after extended driving, typically after accumulating 100+ miles and then resting. One owner had two consecutive Santa Cruz vehicles with identical symptom; first vehicle was replaced due to 'engine failure.'
When: Under 800 miles on second vehicle (complaint #4); pattern occurs after day of heavy use and overnight rest
Symptoms owners cite: Engine knock on cold start; Knock occurs after rest following extended driving
Repairs/costs cited: No repair outcome stated; owner reports continued issue despite multiple dealer and corporate contacts.
Recalls/TSBs owners mention: First vehicle replaced due to stated 'engine failure.' Second vehicle exhibits same symptom; corporate and dealer have not resolved issue.
Engine Stutter and Stall
Engine stutters at idle and random times, and stalls while driving. Vehicle enters limp mode or shuts down completely, requiring restart. Occurs multiple times within first 1,800 miles on one vehicle.
When: First occurrence at less than 500 miles; subsequent stalls at 6/12/2022 and 6/26/2022 (complaint #7); random occurrence (complaint #8)
Symptoms owners cite: Engine stuttering; Engine shaking at idle; Complete engine stall while driving; Limp mode activation; Loss of power and acceleration (shuddering, shimmying); Inability to exceed 25 mph at slow crawl
Codes mentioned: DTC 65312 (Engine Control System fault, complaint #6)
Repairs/costs cited: Complaint #6 (DTC 65312) taken to dealer; dealer could not diagnose root cause. Complaint #7 owner did not report repair attempt. Complaint #8 owner unable to schedule service for weeks.
Recalls/TSBs owners mention: No recalls, TSBs, or warranty resolutions reported. One complaint mentions dealer unable to find problem (complaint #6).
Transmission Power Loss and Shift Failure
Transmission loses power or fails to shift, leaving vehicle immobilized or unable to accelerate. One vehicle required complete transmission replacement at 20K miles.
When: 20K miles (transmission replacement, complaint #14); complaint #15 does not state mileage
Symptoms owners cite: Loss of vehicle power; Inability to shift transmission manually; Transmission system error messages
Repairs/costs cited: Complaint #14: full transmission replacement performed under warranty at 20K miles. Complaint #15: no repair details provided.
Recalls/TSBs owners mention: Complaint #14 transmission replaced under warranty. No manufacturer response or TSB mentioned for complaint #15.
Radiator Puncture
Radiator punctures and leaks coolant after exposure to road debris. Dealers deny warranty coverage, citing customer damage or road hazard. One owner notes wide front grill design may allow objects to enter more easily.
When: 13K miles (complaint #13); exact timing not stated for complaint #10
Symptoms owners cite: Coolant leak; Low coolant level; Radiator puncture
Repairs/costs cited: Dealer estimates repair cost not covered under warranty as 'customer damage.' One owner reports dealer attributed puncture to rock strike from road.
Recalls/TSBs owners mention: Dealers denied warranty coverage on basis of road hazard/customer damage. No recall or TSB mentioned. Owner notes wide grill design may increase susceptibility to debris ingestion.

What owners are reporting 2 most recent
Radiator spewing coolant. Had not hit anything only driving on back highway. Dealer stated not warranty customer damage. Happened at 13,000 miles and vehicle less than I year old.
Leaving work my truck started shimmying like I had a flat. I realized I had no power when accelerating and my engine light came on. I wanted to make it home so chanced it in the interstate. Any acceleration under 2000 rpm my whole car shook and shuddered. It even shakes when idling before I shut it off. The dealer said they can’t even schedule it for service for weeks.
