I have a 2006 Chevy Uplander that was recently involved in a very minor fender-bender (the fenders weren’t even bent). Someone in a Ford F150 pick-up truck rear-ended me at a stoplight. I have a hitch-mounted bike rack at the time which seemed to take the brunt of the impact, since I could see no damage to the rear bumper.
However, the next day I got a very strong rotten-egg smell inside the van, which occurred several times and dissipated over a couple of days. A local shop had a look at the frame to see if maybe the rear hatch was not sealing properly, but couldn’t find anything.
This morning the van would not start. When I turned the key it made a couple of clicking noises, but would not turn over. The lights, radio and dash lights etc. do come on, but no luck at starting.
Do you think the impact could have damaged the battery, or charging system? I was wondering if the smell could have been coming from a leaking battery, since the exhaust did not seem to have the rotten egg smell when it was running - I think it was getting pulled in by the fresh air vents from somewhere under the hood.
