Visual Red Triangle code illuminated on the instrument cluster with the number 1 on the side of it. I used my OBD2 reader (Blue Driver) to retrieve the 8 AIR BAG codes. They were B1511 ,B1513, B1378, B1382, B1346, B1481, B14AE, B2618. Problem resulted after the Cowl Cross Bar Assembly (Unpainted), also known as a CRASH BAR, was replaced because of broken welds. It was replaced with a Painted Assembly that prevents access to secure ground for the Air Bags and Seat Belts. The Assembly is used to provide support in case of a crash and also serves as a grounding bus bar for multiple devices, such as; Air bags, seatbelts, Instrument cluster, on board safety cameras, lane, backup warnings, etc...

While driving in the fast lane on the freeway at speed limit the car suddenly began to slow/stop, after which a warning flashed on the display that said Danger, collision imminent, or something like that. There was no one close in front of me when that happened. This exact scenario has happened three times now in this car, in the same way! I felt my life was endangered every time by the sudden and unnecessary braking of my car.

10/22/21, Mileage ~720, while driving on the highway I had two incidents when the car did not respond to throttle application. In the first instance while attempting to accelerate mildly on a level road the rpm went to 3500 with no acceleration. I backed off the throttle and the car resumed normal operation. In the second instance while attempting to accelerate mildly on a level road the rpm showed about 1500 with no acceleration. I backed off the throttle and the car resumed normal operation. I had no further incidents and returned home safely. There were no warning lights, messages. This is the first problem I have experienced. I think this may be a transmission problem. Similar incidents have been reported online by Hyundai owners with the wet DCT that my car has. I have not yet contacted my dealer about this problem.

Car would not start; battery was too low to activate lights or locks, let alone starter. An attempted jumper cable connection to an older car was insufficient to make the motor turn, even after just running the assist car while connected for 20+ minutes. A subsequent jump from the AAA 2000 Ah jump pack did work although their ‘test’ indicated battery state-of-charge and state-of-health to be less than 30%. Their obvious recommendation was battery replacement and, with the vehicle now running, a drive to the dealership was attempted. At the first intersection a full vehicle stop engaged the engine Stop-Start function, but without sufficient battery for the ‘Start’ part. Not only would the vehicle not restart but there was insufficient battery power to put the transmission into PARK nor engage the emergency brake to prevent the vehicle from rolling into busy cross-traffic; only the service brake worked. Fortunately, a nearby motorist recognized the emergency and placed rocks under the tires to prevent the vehicle from rolling forward. The vehicle was towed to the dealership where the battery was replaced without significant comment on the total failure of nearly all systems in the event of battery failure. The outcome of this major battery failure could have been catastrophic as the ONLY system even marginally functional was the non-power-assisted service brake.

Smart Cruise Control relies on the inconsistent and consequently unreliable performance of the of the front-mounted radar. Otherwise-reasonable operation of the Cruise Control would abruptly terminate 1/3 to 1/2 of the intended use-time, illuminating the master warning light (the amber triangle with internal ‘!’) that was accompanied by either a ‘1’ or ‘2’ encircled by red and may or may not have included the Collision-Avoidance warning light. Subsequent examination of the rectangular shield in the center of the grill very rarely revealed more than 2 bug remnants. When the Smart Cruise Control was in operation it would abruptly apply the brakes when approaching or passing a truck in the lane to taffiche right. There appeared to be no similar conditions to the size or shape of the truck or trailer when these events would occur. None of these events applied to congested tr conditions, just otherwise open road. The ’21 Hyundai Santa Fe does not appear to accommodate any mechanism to revert to conventional cruise control, omitting the influence of the erratic front radar system. Trips to two dealerships have yielded no redress to this malfunction.

I bought a new 2021 Hyundai Santa Fe SEL in January 2021. The vehicle occasionally will not shift out of first gear unless you slow down to almost a stop and then accelerate again. It began within the first month or two of owning. Hyundai has had it in the shop three times. Two times they said they couldn't duplicate. One time they said they showed it went to 4000 RPM's without shifting on the diagnostics before it was slowed down as I told them. They did an update on the TCU and reset the transmission on May 10, 2021. On August 4, 2021 the transmission stuck again. (It went to 5000 RPM's without shifting before I slowed it to almost a stop) This problem has happened about eight times since it began. The GM at the dealership I bought it from said Corporate wouldn't buy it back or get involved without them duplicating the problem. I emailed Hyundai consumer complaints on August 17, 2021 and on August 18 received an email stating I had a case # and would be contacted shortly. On August 24 I called Hyundai customer complaint and was told I had a case manager assigned and they had until August 31 to reply. They did not reply and on September 1, 2021 I called Hyundai complaints again and they said I did NOT have a case manager and that they had not sent it to corporate yet but someone would call me at some point. I feel Hyundai is not concerned about this dangerous problem with their vehicle or my safety. I am beyond frustrated. Jeremy Kimrey
