Assist problems of the 2022 Hyundai Santa Fe

The steering wheeled locked up and the dash showed error messages of check hybrid system and refill inverter coolant and car seemed to go into limp mode as I could barely accelerate forcing me to pull over. The messages and issue would go away upon turning off car and turning it back on, however the issue would eventually happen again. This has happened while driving on the highway and other various road situations without warning and making the vehicle very unsafe. I have taken my vehicle to Hyundai ourisman in bowie, maryland (the dealership where I purchased the vehicle) three times over two years and they have failed to fix the problem. They have even replaced the battery in the car.

Driving along, merging onto interstate, various warnings such as check lane keeping assist, and warnings to stop vehicle and check brake systems. Driving approximately 50mph, the warning started to flash and speedometer dropped to zero then went back to full speed. Automatic braking was attempting to slow the car. Attached photo shows an indicated speed of 0mph, however was travelling approximately 50mph at this time. I also have video of the errors occurring, but there is not a way to upload video.

When lane follow assist(lfa) is engaged, the vehicle is expected to steer itself following lane markings. In freeways. Even when engaged, at certain times, the vehicle disengages this feature possibly to due to failure to detect lanes or due to any other issues. This disengagement happens without any audible notice to the driver. All that happens is a very small icon in the console turning white from green. This can be easily missed as it can be easily hidden behind the steering wheel. Moreover, it's not safe to keep looking into the console when the driver is supposed to watch the road ahead. As heard, this issue is present in many Hyundai vehicles. An audible warning and bigger icon notification are most important for these safety critical situations. A driver may never know that the lfa is disengaged and probably can be in a collision before the driver realizes it. This is an important safety issue.

Car's power steering has suddenly stopped working twice while I was driving. -- first time occurred on 7/24/2022. I was driving approximately 30 mph at the time. I was able to retain control of car and safely park. When steering stopped working, steering light illuminated red. I also got warnings about lane-keeping assist and blind spot detection features. According to Hyundai customer portal, car recorded the following dtcs (diagnostic trouble codes): -- * c168886 (system: chassis; sub-system: lkas) * c240162 (system: chassis; sub-system: eps) -- after I turned car off and back on twice, warnings cleared and power steering started working again. -- I had car transported to nearest dealership. -- dealership's service department investigated and indicated the following: -- scanned system for codes found history codes c240162 motor ciruit c16886 mdps c168881 mdps signal c168808 mdps signal history. -- their corrective action was as follows: -- checked ground connection for mdps. Good. Found loose connection at driver's left foot kick panel loose. Cleared codes and test drove vehicle 3 miles operating normally -- however, when I picked up car on 7/29/2022, immediately after exiting dealership's parking lot (while driving at low speed), power steering suddenly stopped working a second time. There were similar warnings (probably about lane-keeping assist and blind spot detection features again), but Hyundai customer portal shows no dtcs this time. -- I returned car to dealership's service department for them to investigate further. -- sidebar: a coolant line in car's engine compartment was replaced in June 2022 due to rodent damage. When dealership was first looking at this steering issue, I reminded them of that occurrence and requested that they consider possible rodent damage to electrical system as a cause of the steering issue. They did not notice any such damage.

What component or system failed or malfunctioned, and is it available for inspection upon request? warnings appeared on the instrument panel at the same time the power steering would go out and I would not be able to safely steer the car. This happened on 4-5 occasions. These are the various warnings that would appear: check lane following assist system check blind spot safety system check driver attention warning system how was your safety or the safety of others put at risk? not being able to steer was very concerned and happened to me while driving on a busy highway at one point. I could barely steer the car well enough to get it to the shoulder. I had to cross 4 lanes of traffic during rush hour. Has the problem been reproduced or confirmed by a dealer or independent service center? I had it towed to the dealer the final time it happened. They stated that it is a problem with the power steering module has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? crossroads Hyundai of loveland inspected the vehicle were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? no, not until the moment the issue occurred. The strangest part of the issue is that after I would pull over and stop the vehicle, I would clean the sensors on outside of the car and on then restart the car and then sometimes it would work again. It seemed to happen on days that there was poor weather or messy roads that would impede the sensors' abilities.
