Certified Used Vehicle Troubles

I purchased an 06 GC 5.7 Ltd on October 7th as a Certified Used Vehicle from my local Jeep dealership. On the way home, the airbag malfunction light lit up. I called the dealer. They told me to bring it in Saturday, the 9th. I did. Later in the day on the 7th, I set out for the grocery store. Jeep wouldn't turn over. Jumped it. Started right up. Called the dealership. They said they'd look at it Saturday.

Saturday, the 9th - dealer put new battery in, told me the seat frame was misaligned and they'd have to order parts. Told me to drop it off on the 14th. Repair Order stated as much.

13th - dealer called, said part wasn't in yet, drop it off on the 24th; which I did, along with a letter citing the following items that presented themselves over the past couple weeks that needed fixed also (called the next day and mentioned the passenger side vents (front and rear) needed repaired, too) :

  • ‘Fasten Belt’ warning light on dash stays on when nobody is in passenger seat and I am in drivers seat with seatbelt buckled. When I plug the passenger seatbelt in with nobody in the seat, the light goes out. Additionally, the ‘back’ portion of the passenger seat heater does not function.
  • When someone is in the passenger seat with the seatbelt buckled, the ‘Airbag Malfunction Light’ comes on intermittently (about 60% of time). This light will occasionally turn on and off several times during a trip of 30 minutes or so.
  • There is a pronounced shudder and vibration through the entire vehicle when driving at a steady speed of 65-70 mph. The shudder varies in intensity, occasionally getting more pronounced, but never goes away completely. The Jeep shudders as if a wheel weight has fallen off, but the Certified Used Vehicle documentation states that the wheels were force-balanced. I have spoken with several Jeep owners that have had work done so as to alleviate a similar shudder. It seems several curable conditions may exist that could contribute to this shudder/vibration. One possibility is the front differential center isolation bushing. When the truck is driven forward, stopped, then put in reverse, a sharp pronounced ‘clunk’ comes from the front differential. While inspecting it during this ‘clunk’, I noticed that this bushing has significant play in it and seems to have failed its intended purpose.
  • After the vehicle has been parked overnight, the front limited slip seems to be nearly completely locked for the first 20 minutes or so of driving. It literally scrubs (crow hops) the front tires so bad that I’ve had to back up at the end of my driveway a couple times to make the 90 degree bend onto the township road. I’ve consulted with several people on this and the consensus seems to be either the differential fluid and friction modifier are fouled, or one of the wheel speed sensors is bad. If I remember correctly, this Jeep had the diff & x-fer case fluid changed as part of the Certified Used Vehicle process, since it had over 30,000 miles on it and no maintenance records existed to indicate it had been changed previously.
  • I purchased this Jeep as a Certified Used Vehicle on October 7, 2010 w/ a 3 mo/3,000 mile bumper-to-bumper warranty and the remainder of the 6 yr/80,000 mile factory warranty.
  • After I purchased the Jeep, I was told that only one (1) key existed. I’ve purchased a blank key with transponder & remote (enclosed). The sales manager told me that the dealership would waive the cutting and programming for this second key.
November 2nd - dealer called, said more parts needed, asked if I needed a loaner car. Indeed, I did (had been driving the 350Z, but the weatherman keeps making threats about snow).

November 11th - dealer called .... module, passenger seat sensor replaced to no avail. Airbag malfunction light still coming on. Mentioned that the 'crow hop' was taken care of by way of some friction modifier in the rear differential. Told me they would continue to diagnose the problem and get back to me. Said they hadn't gotten to the front diff bushing yet.

All that being said, as much as I hate to even think of the notion, has anyone ever used the Magnusson-Moss Act in such a way that the dealer buys the vehicle back? I've read up on it a little, and it sounds like this kind of problem is exactly what the Magnusson-Moss Act was created to remedy.

I'm at my wit's end. I'm keeping my fingers crossed that the dealer calls me in the next couple days to tell me all is well, but, if not, I would really appreciate any and all advice you all could give me.

Re: Certified Used Vehicle Troubles

you need to have the seat calibrated. they have a dummy sit in the seat while it is attached to starscan. there is a scale in the seat to measure the weight and it needs to be calibrated.

Re: Certified Used Vehicle Troubles

I purchased a new 2000 GC Limited V8 4x4 back in 1999 and it had more issues that I could type here. It was in the shop every week. I kept it 5 years and it had 40,000 miles on it, 20,000 taking it back and forth to the shop. I ended up just trading it when I should have filed and had Chrysler buy it back.

On the front scrubbing issue, My 07 does that aswell and I just assumed it was out of alignment.

Re: Certified Used Vehicle Troubles

I don't know if I'm giving them too much credit here, but shouldn't the 'best technician' at a 5-star dealership know this? And certainly, given the truck has been at the dealer for nearly three weeks, they've had plenty of time to investigate this sort of thing. I'm at a loss. I can only imagine the response (and future service) I'll get if I call the Service Manager and ask, "Have you guys calibrated the seat?". And I'm not really sure it's my place. I mean, people don't call me when they're driving past a power plant and ask me if I've accounted for the Method 5 condensate considerations for the stack testing. Oie - I'm so frustrated.

I'm thinking that's the route I may end up taking. I guess the M-M Act has provisions for buying the vehicle back, having someone else fix it, or having the seller pay the depreciation amount due to the malfunction. What a mess.

As far as the front diff goes, I took a ride in my buddies WK and it turns smooth as silk all the time. Mine seems to bind up after sitting for a while, but then frees up after 15 or so miles. I plan to change the diff fluid when (if) I get it out of the shop.

Re: Certified Used Vehicle Troubles

Here's my update as promised.

Dealer replaced strain gauge frames and sensors, along with all lead wires in passenger side seat. Air bag malfunction corrected.

Dealer programmed and cut second key free (after I had to shell out $150 to buy it).

Vibration was from a wheel weight that came off. Corrected.

Dealer added friction modifier to rear diff; claimed crow hop was corrected. It wasn't. I was under the truck last night and, contrary to the claim on the Certified Used Vehicle checklist, the plugs on the transfer case and front diff still have the factory marks on them! That's disappointing. Gotta stop at Pep Boys to get the necessary 14 mm hex for the front diff plugs, then heading home to change the fluids.

IMHO - This is all stuff that the Certified Used Inspection Process should have caught. The dealer was nice enough to give me a loaner car and waive the warranty deductible, but they shouldn't have needed three weeks to fix a seat sensor in the first place.

Didn't address passenger seat heater or busted vents. Told me they would let me know when the vents came in.

Guess ya gotta take the good with the bad. As far as I'm concerned, the 'Certified' stamp simply means you get a loaner car and 3-month warranty -- nothing more.

Re: Certified Used Vehicle Troubles

I think that you'll find that many Chrysler/Jeep dealers are probably the least qualified to work on your Chrysler/Jeep product. The few times I've taken either of mine to the dealer, I've had to tell them what the problem was, and how to fix it. Under warranty is the only way I'd ever take it to them again, but all warranties have expired. Fortunately, neither my LX and WK have not had any serious issues.

IMO, you'll be way ahead of the game by coming to these forums before you head to the dealer with any problem. Just about any problem you could encounter has happened to someone here, and valuable knowledge and insight can be gained so that when you do end up at the dealer, they'll have a tougher time BS'ing you about what may be wrong. Keeping good records, like you're obviously doing, is a also a great idea, in case you need to take more serious action in the future. Your timeline so far shows me they're making like parts replacers hoping to hit on the right item. Doesn't anyone do actual troubleshooting anymore??

Re: Certified Used Vehicle Troubles

I don't know anything about the M-M Act, but if it's what you made it sound like, I'd look into that more. Also, get anything and everything that you can in writing from the dealership. You may want to speak with an attorney that is familiar with the M-M Act and see what they have to say.

On another note, I've seen plenty of certified pre-owned vehicles that were previously wrecked. The dealerships will certify pre-own anything that looks pretty and doesn't have any wrecks on the carfax.com reports. There are used car buying checklists that you can find on google that are very helpful. I know those aren't too helpful for you right now, but keep that in mind for the future. Good luck and keep us updated.

Re: Certified Used Vehicle Troubles

I hear ya. Most of my used cars didn't have any warranty at all, so I did most of the work myself, with the help of forums like this and a trusty Haynes manual. Trouble is, these days, time is at a premium, so I figured I'd be doing myself a favor by purchasing certified. Should have known better. Good news is, I got a pretty good deal on the truck and they did ok on my trade, so, it could be worse. As it stands, seeing as they fixed the airbag malfunction - the problem that could have been most costly, I'm taking it as a win. Overall, the truck is in great condition (minus all of the maintenance-type items that should have been done during certification), so I'll just make the time to catch up on the maintenance and I should be all good.

Well through many posts and thread people have started we've all come to one conclusion that DEALERS are RETARDS ... they never know what they're talking about and are the morons of this planet. Don't even get me started on the useless fawking service managers who think they're smarter than you and when you do let em know something they can't accept the fact that you have just schooled them on a products they're supposed to have knowledge on.

Anyways, what they said above the seat has to re-calibrated the shudder feeling ... check out the wkjeeps.com for some TSB's for that.

Other than that you should be fine, but I would honestly go with a mechanic who knows what they're talking about so you can avoid paying up the ass fees with dealership if you have warranty see if it can be applied somewhere other than retard land

Re: Certified Used Vehicle Troubles

First of all, Certificate Used or Pre-Owned Certificated are BS!!! Is just other way to rip you off. As far as the airbag problem, you might wanna consider replacing the seatbelt tensioner. This kinda of problem happens when one of the seats was replaced. I know that because I installed a set of leather seats from an 06 to my rather bare bone 05 laredo. In fact the dealer told me that if one of the airbag is deployed, it is very difficult to get the hold Jeep's air bag thing working properly again. My advice to you.. Check car-fax.

Re: Certified Used Vehicle Troubles

we bought a CPO Commander Limited 18 months ago. it's been at the dealership 22 times since then. my wife loves it when it's not at the dealership. it's so friggin frustrating because it keeps going back for the same things (mainly windshield and sirius radio).
