I have a 2010 GMC Terrain SLT (79,000 miles). Doesn't turn over to start?

Asked by migration_yukondom Jun 23, 2015 at 12:37 PM about the 2010 GMC Terrain SLT2

Question type: Maintenance & Repair

I have a 2010 GMC Terrain SLT (79,000 miles). I seem to have electronic function (battery seems good) but doesn't turn over to start? The battery is kind of sensitive and has needed to be jumped about 4 times (hazard lights etc). Has this possibly killed the ignition starter?

If the battery is more than 3 years old then get a new battery. That is the cheapest thing to do... A new starter should last more than 79,000 miles.

I agree with cartercanes. 79,000 on a 5 year old car indicates a fair amount of highway miles, not like you start it 6 times a day and wore out the starter. Make sure battery terminals are clean and tight, new battery or not. Test battery ground by putting a jumper cable from neg-- battery post to a good ground on chassis. If it starts then, your ground cable is loose or bad

If you have a bad cell in the battery, "common problem" it will have power to run the electrical but not enough to run the starter. Make sure when it is finally running you are getting charge from the alternator. If you are, that that is a good indicator the battery and or connections are bad. I'd give it a 98% chance the battery is the problem. All the above answers are great suggestions.

There's something more than "dead battery" wrong with Terrains and Equinox's. The battery becomes completely disconnected from the power supply system and won't reconnect until the alternator sends amperage. Jumping it works great - and if you turn off the engine right away, it'll restart as if it LOVES your old battery ; like there was NO problem ever. These cars have some great engineering, and some REALLY bad electrical, transmission, and engine ring issues that they are remiss to address. Of course, check your battery terminal connections, but I think it's a brain problem. -- Still working on it, because GM isn't.

I’m having the issue of sporadic failure to start. New ignition switch, good modules, new starter, good alternator, all accessories come on, new battery, good cables and sometimes if you come out 5 min later it will start right up?

oldb52guy58, did you ever figure out what the problem is with the gmc terrain no start problem? i have the same issue

The first time I thought I had it fixed, I had replaced the master fuse (80amp?) after ohming it as "bad." ?? Worked fine for a while. Then failed again. This time, I felt really stupid: the positive battery terminal connection (which hides under the fuse panel) was just a wee tad loose (again poor engineering). Tightening fixed the problem. ALAS, with this car, it was the beginning of sorrows. The engine rings start to fail at about 45k. Then, by 75-85k they start allowing "blow-by" which creates excessive oil consumption out the tail-pipe (I'll bet you're already wondering why it's down a qt or so each time) and so much positive internal pressure that it eventually blows the engine-to-transmission oil seal. ($1,500 - $2,000 because they have to drop the engine and tranny.) Within a month or so, you'll blow another seal! All the time your catalytic converter is working overtime to stop you from seeing or smelling the blue smoke that should be pouring out of your tailpipe... and it too will eventually fail. -- Plus 02 sensors, etc. I'm tellin' ya = 2010 - 2014 GMC Terrains are MAJOR lemons. There's already several class action lawsuits out there. GMC won most of them, or waited out the owners saying "Tough, sh*t! You got over 100k, and 7 years. Not our problem now." Keep driving this POS at your own risk. My advice: Trade it in while it still runs. Love ya!
