NHTSA Complaint #11476893 — 2014 BUICK VERANO

All occurrences happened on city streets and all during the daytime. First time this occurred was on 6/15/2022 with 148,467 miles. It went to the dealer. Lots of low voltage and lots of comm codes stored in a lot of modules. All were cleared out. They could not replicate the problem. Then it occurred again on 7/23, 7/24 and 7/25. Then on 7/26/2022 (twice) with 151,261 miles and again at 151,264 miles. Then 08/01/2022 at 151,475 miles four to five times. And so it goes. The car suddenly lurches like it’s downshifting. If you were to keep driving the car, the transmission does not shift. The faster you go the higher the tachometer goes. When I took it to the dealer, I had to use the highway. Could not go above 60mph. The tach reading was too high. All four door locks start unlocking and locking and they keep doing this till you shut the car off. Vehicle chimes start going off. A “Service Power Steering” message appears on the center message board. A “Service Stabili Trak” message appears on the center message board. A “Service Parking Assist” message appears on the center message board. The Malfunction Indicator Lamp icon is on. The Brake System Warning light is on. After pulling to the side of the road and you put the car in reverse, there is no backup camera picture. After shutting the car off and then restarting it, all is well until it happens again. Since the first occurrence, I’ve also noticed when using the remote control FOB, the car starts then shuts off within three seconds. But it does not do this every time.
