Apparently a VERY common crankshaft angle sensor malfunction caused the engine to stall out at a stoplight, putting me in harm's way

*Wife litely drives this car avg 4k miles a year* She left the house for the grocery store the other day and after the first stop light, noticed the brakes were engaging on their own. Luckily she called me before going any further and damaging the pads and rotors, or worse - causing a fire or having an accident. I slowly drove it home and inspected fuses, brake fluid and checked online resources for anyone with similar issue. Turns out this is common? Very dangerous. Have never experienced this issue with any other car make. I had the car towed to HQ Hyundai (local dealer in Sanford FL) to address 2 open recall bulletins on this car. They immediately forced me to accept a $200 inspection fee (key ransom) just to do the recalls - siting safety of staff!?! They were informed that the brakes were remaining engaged and that they needed to disconnect the battery, but they left it in the tow yard over the weekend. I am sure they will try to sell us a battery now. Very upset with the response to this extremely unsafe issue, that we didn't cause from excessive, hard driving.

To Whom It May Concern, I am submitting this complaint regarding a 2012 Hyundai Elantra equipped with the 1.8L Nu engine, which is experiencing premature internal engine damage that presents a potential safety risk. Vehicle details: Year/Make/Model: 2012 Hyundai Elantra Mileage: Approximately 134,500 miles Issue description: The engine produces a persistent ticking/knocking noise, most pronounced at cold start but now continuing even after the engine has warmed. A Hyundai dealership diagnosed the vehicle with piston slap and confirmed significant scarring on the cylinder walls, stating that the only repair is full engine replacement. Despite the presence of internal engine damage, no warning lights are illuminated. I am concerned this condition could lead to sudden engine seizure or loss of power while driving, creating a safety hazard. Additional observations include: Excessive crankcase blow-by observed when removing the oil fill cap while the engine is running Strong exhaust fumes at cold start Noise most noticeable at idle and low RPM Regular oil changes using manufacturer-recommended oil viscosity The dealership advised the condition was not repairable short of engine replacement and did not submit the concern for Hyundai corporate technical review (Techline), despite the known history of engine defects in Hyundai Nu engines. I am filing this complaint to document a pattern of premature internal engine wear that may not be adequately addressed through recalls or warranty programs, and which could result in sudden engine failure. Thank you for your attention to this matter.

Car check engine light illuminated and car began shaking and stalled at 79284 miles. Local mechanic said engine was dry and would need full replacement, no dashboard lights indicating oil level or engine issues prior to this point.
