2007 Cadillac SRX Q&A
2007 Cadillac SRX Question: Car nearly shuts down while driving at highway speed.
Very serious engine shutdown while foot is still on gas pedal(not off), while driving freeways at 65mph. After slowing down car will accelerate with a surge. Occasionally same thing while driving away from full stop and then a surge because foot is still on gas. From dead stop,occasionally car will die completely when trying to accelerate from stop. - Rich 65
This isn't an answer, but we seem to share the same problem. My 2007 Cadillac Escalade does the same thing. I bought the truck brand new. I take it to get regular maintenance, i.e. oil change, inspections, etc. Right now it's at the dealership so they can hopefully find the problem. I've never heard of this happening to anyone before..ever! When I hear something from the service department, I'll come back and post their findings. I have a feeling they're not going to find anything and clear me to drive off the lot. If so, that won't be the end of it!! - MackRivers
MackRivers: Got my vehicle back from Cadillac service department on 03/08/11. I was told that my battery cables on the engine side had a lot of corrosion and that caused my electrical system to get out of factory specifications. So they cleaned my cables and somehow reset my electrical system back in spec. So far no problems. - Visitor
Hi. I have endured an extremely long period (18 months) of similar issues with our SRX. After numerous dealer and independent shops and replacement parts like Throttle Position Sensor (TPS), Battery, Throttle Body, TPS electrical plug, it turns out that ALL it took was a replacement FUEL CAP to clear P2135 Code and ALL the issues with unexplained shut downs, surges, etc. The issue is that the cap seal wears out with age and at $12 from most auto supply dealers, FEW repair places suggest trying that first, as it is easier to change out parts as I said above (lots of $$$) and "Clear the codes", as that is how they make money. Also...it takes a couple run cycles to have the lights stay off, as the system needs to properly pressurize and STAY that way. Good Luck! - BLK SRX V-8
