My wife has had our HHR stall on her twice. Both times she hit a big pot hole. Both times she was able to re-start the car by putting the car back in park, turning off the ignition and then turning back on.

Has anyone seen any TSBs on this?

 

do any of the posters in this thread have any updates on their situation in regards to this? we have been experiencing this too and my wife is getting a little freaked about driving on the highway because of it.

the car stalled twice hitting a fast food driveway and once today when she hit a dip in the road.

 

There have been many issues with loose fuses in HHRs since the fusebox is located directly over the front suspension, and takes a lot of "hits" from the bumps. If you already had some loose fuses or relays, it is possible that one "of great importance" might be knocked out of place from a bump, causing the engine to shut down.

Just a theory, but from the great number of HHR's we see with loose fuses - it would be the first place I checked. Pull the fusebox cover off and re-seat all the fuses and relays - while you're there, take notice of any that are extremely loose.

Here's a how-to from our website:

Underhood Fuses

Hope it helps,

 

My Camaro died doing 88 down Interstate 95 once. That was a real fun expirence, had to spin it into the median to avoid the semi behind me. I replaced the entire engine after that.

 

is it only sticks that are having this problem

 

YIPE!! Did you have to replace your shorts too after that thrill ride?

 

CHeck the headlights and make sure ther not shorting out. I had a cobalt and this is a known error on them. hit a bump and the car cuts off.

 

I have a 2006 HHR and the other day on the expressway we hit a bump and the car died at 70mph!! I freaked but my husband was driving and coasted onto the off ramp, put it in neutral, turned the key off then on and it restarted. He says the HUGE bump we hit (it was bad) shut the fuel pump off? He designs cars for a living so I do believe him but I called dealer anyways. I have to take it in this week b/c dealer said sounds like it could be electrical? Car drives fine and only happened that once I hit that pot hole but I will feel better having it looked at? Scary

 

I went to the owners manual, but couldn`t find any ref. to a fuel shut-off or reset button on the HHR.
My experience with other cars that had electric fuel pumps, was there was a reset.
Is there one on the HHR, or does turning off the ignition do that?

 

I guess BB is as confused about this fuel pump shut off, as I am.

Srogers....I believe your husband may have been speaking of a new safety factor, I heard of, that is built into most vehicles with electric fuel pumps. In the event of a severe collison, particularly from the rear, the fuel pump shuts off to prevent a potential fire. I'm doubtful if your severe BUMP would have been that severe to turn the fuel pump off.

Your problem sounds more electrical, to me.

BB...know of no way to reset the fuel pump, manually. I do know that the "hot feed' wire to the pump is an excellent way to utilize a hidden theft prevention switch.
