After Nissan dealership updated ecm on 6/1/2026, the mil came on with code p0101. This causes the car to go into limo mode while driving on the highway. I took car back to Nissan who said they needed to clean the wires, which they did and cleared the code. Again while driving the car went into limo mode. Nissan now says I needed an $8,000 new computer. Again the car went into limo mode while driving. The car can be driven but randomly goes into limo mode. This only happened immediately after the ecm update in June 2026, and may cause an accident if it continues to randomly go into limo mode.
