After update, the car sputters slightly and increased noise is heard from the tailpipe. Customer returned to dealer after driving the car in different temps and noted the above complaint. Dealer verified the complaint but continues to take no responsibility for the fault on the repair receipt by writing condition is “normal” and recommending “customer to allow vehicle to properly warm up for one to three minutes prior to driving.” The last line of the service record indicates “no problem found at this time.” A template letter from Hyundai was attached to the repair record. Hyundai may be instructing dealers to not document problems in the service records assumably so they will not be liable for future litigation. It should be noted that owner was previously denied payment on their 2017 Hyundai Tucson due to lack of documentation by the dealer to prove the case with prior class action lawsuit despite years of verbal complaints to the service staff. Dealer may be intentionally not documenting or taking responsibility for systematic failures in the Tucson in service records. This may be on the direction of Hyundai corporate. 2020 Hyundai Tucson continues to sputter periodically during normal driving conditions. Car is parked in an attached garage making a 1 to 3 minute warm-up time-consuming and possibly unsafe. This required warm up should not be considered normal as indicated on the repair record. Hyundai should take responsibility for their shortcomings and allow proper documentation on service records rather than pushing the fault on the owners. As with previous Tucson complaints, the dealer continues to indicate the problems are the result of owner actions not internal failures.","products":[{"type":"Vehicle","productYear":"2020","productMake":"HYUNDAI","productModel":"TUCSON","manufacturer":"Hyundai Motor America"}]}]}
