VEHICLE SPEED CONTROL
I have spent over thousands in 2024 in a small amount of time, going to multiple shops, trying to figure out issues. I have been told these models are known for having ECU and electrical issues. My car will not set off any codes. I have greatly maintained my vehicle. I have had my keys reprogrammed, 2 new batteries, 2 new alternators, all new 6 fuel injectors, new MAP sensor, all new spark plugs and plugs, had my engine and transmission inspected, and when I am in traffic WITH MY KIDS IN THE VEHICLE the immobilizer will set off and bog my car out in traffic and highways. This computer and electrical system is horrible and dangerous. The electrical is parasitic draining my alternator and battery although I have replaced twice in 2 month. No shop can figure out what is wrong with the ECU and electrical. It is draining my pockets, and putting my children and myself at saftely risk. I have done extensive research on this issue. I have seen many people, same car, same issue. Please help. My car will turn on and run fine. Put me in limp modes and even just bog out in traffic. I am very concerned.

I visited Mission Hills Hyundai located at 10240 Sepulveda Bl, Mission Hills CA 91345 on Jul 31, 2024 for recall after appointment. I waited 2 & half hour, and Hyundai told me the recall service completed but not done. It was perfectly lying. Hyundai explained my car's break disc has problem and cut it and then put together, but only done for resurface. They charged $824 as a labor. Please confirm them and recall service was not doing even Hyundai sent recall service letters many times. Hyundai service is not good. Thank you.

MY VEHICLE SHOWED SOLID CHECK ENGINE LIGHT WHILE I WAS ON 101 FREEWAY AND AFTER EXITING TO CITY ROAD I COULD PARK AND READ THE ERROR CODE "P0880 POWER INPUT TO TCM", I REPORTED THE ISSUE TO HYUNDAI DEALER AND THEY DIAGNOSED THE ISSUE AS INTERNAL TCM DEFECT. DEALER REPLACED THE TCM BUT THAT COULDN'T FIX THE PROBLEM. AND THEY JUST RELEASED THE CAR AS IS. AFTER A SHORT WHILE MY CAR HAD BECOME UNABLE TO REVERSE, AND WHEN SET THE GEAR TO REVERSE, MY CAR MOVES FORWARD TO MAKE A VERY LIFE THREATENING. I CALLED HYUNDAI CORPORATE OFFICE BUT THEY DIDN'T HELP. NOW, I CANNOT DRIVE MY CAR BECAUSE IT IS UNSAFE AND BECAUSE BECAUSE I'M NOT A MECHANIC TO DIAGNOSE THE PROBLEM WHILE THE DEALER AND THE CORPORATE DON'T HELP. I FOUND OUT THAT THE MODEL OF MY CAR IS A SUBJECT TO RECALL FOR GEAR PROBLEM WHICH IS EXACTLY WHAT I FACE NOW. IT SEEMS THAT BOTH OF THE DEALER AND THE CORPORATE OFFICE ARE AWARE OF THE ISSUE IN THIS PARTICULAR MODEL BUT THEY DID NOT EVEN MENTIONED IT TO ME UNTIL I FOUND IT BY MYSELF. A CAR LIKE THAT IS UNSAFE FOR ME TO DRIVE BECAUSE IT RUNS FORWARD ONLY EVEN WHEN THE GEAR IS REVERSE AND IF STOPS I CANNOT EVEN PUSH IT BACKWARDS. A CAR WITH THIS DEFECT IS DANGEROUS FOR MY COMMUNITY. PLEASE HELP TO FORCE THAT COMPANY EITHER REPLACE THE CAR FOR ME, REPURCHASE OR REPAIR IT TO FULL OPERATIONAL STATUS..

MY CAR WAS PERFECTLY OPERATIONAL BUT SUDDENLY DURING REGULAR DRIVING ON THE 101 HIGHWAY IT SHOWED SOLID CHECK ENGINE SIGN. I CHECKED THE ERROR AND IT READ P0880 I HAD TAKEN MY CAR TO THE HYUNDAI DEALER (KEYS) WHERE THEY DIAGNOSED IT AS TCM INTERNAL FAILURE AND RECOMMENDED CHANGING THE TCM AFTER PAYING FOR THE PART AND INSTALLATION ($994.00 AND $162.00 FOR DIAGNOSIS) THE DEALER INSTALLED THE PART AND CAME BACK TO INFORM ME THAT THE ISSUE PERSISTS AFTER PART'S INSTALLATION AND THAT THEY ARE GOING TO WORK WITH THE ELECTRICITY TO FIX THE PROBLEM. DEALER INFORMED ME THAT THEY SHALL WORK ON THE CIRCUITS BUT NOT WITH ANY TRANSMISSION PROBLEM. AS THIS ISSUE HAPPENED WITH REGULAR USE, I BELIEVE IT TO BE MANUFACTURING ISSUE THAT MUST BE CARRIED OUT AND FIXED BY HYUNDAI.
