“I just bought/ financed my new 2020 Hyundai elentra on 11/15/2020 and recently in past couple of days I have experienced trouble with the gas/ throttle/ power of driving my new car. The RPM in my video jumps up & down with no power really pushing to drive. I almost got into 1 bad accident with a semi-truck. Also the tire pressure sensor was low reading PSI of 29 and I never received a warning light until way later for PSI reading 32. Even though I aired my tires to the correct PSI my warning lights are still on.”

“The soldering of the end cap in the engine fuel rail failed and allowed gas under pressure to leak out. Fuel sprayed out in the engine compartment and the smell was evident inside and outside of the vehicle while in operation. Not sure how it did not start an engine fire. Repairing was a simple task that I handled as this is the only vehicle available to me. Ordered a new fuel rail which was only available from a dealer without issue and completing the repair went without issue. …”
