A1 incoming email: letter from consumer re the safety of 2015 Ats Cadillac. The consumer stated while driving 70 mph on the freeway, the fuel gauge completely shut down. Two months later, the front dash computer que reader shut down completely.
Right turn from stop onto major 6-lane highway; no power to engine after engagement of accelerator; acted as though not in-drive gear; tachometer reved past 6k; foot off of pedal; transmission engaged; very slow return to normal operation; evasive action by other drivers following; no replication by dealer after 4-days of testing; returned vehicle to owner without explanation of problem.
When coasting to come to a stop the vehicle engine will stall. This has happened numerous times since the first incident in January. This is a 6 speed manual transmission equipped vehicle, and the transmission is either in neutral or the clutch pedal is depressed so that the engine/transmission are decoupled. I have been able to watch the tachometer when it has stalled twice, and it seems to get to a lower rpm than normal (<500rpm) and then the engine just shuts off, very abruptly. It has also happened when slowing to take a turn with the clutch pedal depressed, which is very difficult to get back started as you are trying to drive and not cause an accident. I have reported this to the dealer, and they have tried to diagnose it, however no fix has happened. It will normally stall about once every week or so, it is very intermittent and seems more often with a higher load on the engine (hot days, a/c running, etc. . . ). The dealer went as far as to blame me for stalling the vehicle, they said I didn't disengage the clutch at a high enough rpm which is completely untrue and regardless the car was in neutral and I was coasting to a stop (therefore it would be impossible to stall the vehicle in gear). I am not the only one with this issue, there have been numerous people on forums complaining of the same issue.
