Grand Design MOMENTUM 376TH 376TH reviews

Purchased new in 2016 (September) from at the time the only dealer in Ontario. PDI was poorly done which as it turns out was only the beginning of the poor quality and engineering of this unit. We do really like the layout and livability of this unit and have used it extensively in Ontario as well as in the USA. Normal highway,interstate and campground driving. Since new we have replaced taps, all tires (China Bombs),light fixture in kitchen, equalizers twice, all leaf springs, rear ladder separated from trailer ( I weigh 185 lbs), front passenger side slide motor ,water damage in rear outdoor kitchen ( floor destroyed ). Door for fridge access outside was improperly installed . Now we have structural failure in front drivers side and delaminating wall that needs to be repaired this winter. Main brain for auto level system failed. All in nearly $30000 in bills when all in. Grand Design basically says so said sucks to be you. We have traded it in for a 2 year newer other brand and will never deal with this company again. Amazing marketers, lousy builder !!! Show less

We've had a number of issues, not real sure if this is normal with RV's but it's been frustrating. We've had an awning motor go bad, shower door leak, front two jacks replaced, generator issues, the undercarriage totally coming down, regulator on LP replaced, refrigerator needing to be "reset", we added a rear camera which the monitor worked maybe a year and most recent our living room furniture literally is peeling away. The vinyl used was about as cheap as they could possibly have chosen. I've been told they've since changed to an upgraded fabric. From what I've been told RV's are made as cheap as possible and we should just accept it or not be RV-ers... We love the RV life and are not willing to give it up just yet. Show less

We have owned 2 GD Momentums since 2016 both a 376th and 397, loved both units especially the 376th which we currently have, we can still take the motorcycle with us and enjoy the full size front living room making it feel more like home. We plan to full time it in 2 years. The only issue we had with both units which has been identical is the dining slide did not function properly, dealers and private RV repair companies were unable to make then function properly when going in and out, the 397 was worked on for same issue 5 times with no success. As for the rest of the units the floor plan is great, plenty of storage and good value for what you pay for it. Would I recommend this brand yes as overall quality they are the best we found for toy haulers and we have looked at every one of them on the market. If GD could fix the slide issue they would be the best. Show less

There were issues to work out as with any new camper. But to not even tighten the tiger clips on all the plumbing pipes? Roof was bad. Moulding falling off. Radio not working?Few other things that quality control didn't see. Went in shop June. Got camper back in Oct. My new camper depreciated in the shop waiting for parts? Manufacture I am ashamed. Alpin Haus dealer doluble shame. Show less

Poor manufacturing quality. Missing to loose screws. Ac vents all 3overtightened and cracked. Shower leaks externally at doors. Rear propane fitting fell off and dragging on ground. Bedroom mattress the worst. Kitchen drawers falling out. Reviewed with warranty department they suggested hire someone to come out and repair. I am living in unit for 3 months and unable to leave at dealer. Very poor quality at workmanship. Magnets for holding side doors open do not line up. Bought in December in cold not able to look over. Would not have purchased Show less

Had nothing but trouble from First day. Rear awning would not extend fully day I bought and had to take camper back month later. Shower soaked floor first time I used and I had to caulk bottom rail of shower door. Furnace showed error code on control panel and had to take camper back to dealer. Now furnace making squealing noise and has to go back again! I would not recommend this brand to anyone!! Garage is excellent and is perfect for Harley Trike. Show less

Glad to find this site. Same problem with refrigerator not closing properly. The middle piece on double door not closing. Read about using washer on it and will try that. Other problem was the awning falling off side of rv. Had it extended and was inside and all the sudden the left side of the awning crashed down. Did call dealer as we purchased it on June 28th 2019 and this happened on July 13th 2019. Had no luck with dealer and finally found an rv place to come out to repair it. Looking at camper it is the left arm bent that comes out ver the dining slide out. Very disappointed!!! Show less

After reading the other poor reviews it makes me feel a lot better knowing my sh**y brand new $95,000.00 2017 grand design 376TH isn’t the only one with major issues. Here’s some of the problems this brand new RV has. RV issues: Outside water hook up compartment leaks into basement area.  Bed motors struggle to raise bed Kitchen drawer has hole inside cabinet on the back wall behind the drawer causing basement heat and or cold to enter kitchen.  Lock latch on door inside the “outside” kitchen compartment is missing.  Bottom of shower door leaks near sink. I caulked everything in hopes of resolving issue. My friends 2016 has same issue.  Refrigerator drain drips everywhere inside fridge despite no obstruction or drain plug outside or in drain line/pan.  I replaced everything and after noticing the drain pan over flowing into the outside fridge slide compartment floor which is now rotted out I rerouted the drain tube. Living room window couch screen liner is not in all the way around screen.  Air gap at entrance door/visible light entering around edges. Poor seal.  Generator won't auto transfer switch power. I contacted Jr at the dealership I drove 8 hours to pick this thing up and ultimately gave up because they were worthless so I contacted grand design which grand design was extremely helpful and overnighted a transfer switch but I still wasted a day removing all the contents of the storage compartment and also the inside walls to swap the transfer switch out myself.  JR promised to send filters/light strip, transfer switch etc. after multiple times contacting it became a lost cause so I gave up and just wrote a bad review. The Outside entertainment center sound does not connect to the outside tv. My friends 2016 has the same issue.  The Fridge door won't shut fully when closed. Inside divider rubbing bottom of fridge.  Black and gray water tank sensors do not read properly. They will read full even after being rinse Many times and drained. Led Light strip behind tv doesn't work. Another thing I spoke to JR about which he was going to ship me a new strip but after multiple attempts to solve the issue I ended up giving up.  Shower drain did not work. I Disconnected everything Under shower pipe and replaced the piece that keeps air from coming back up pipe. Shower now drains most of the time.  Generator door latch is not right and the generator compartment can’t lock. Passenger side compartment turn latch just spins 360 degrees continually.  Passenger side couch is slanted (how the hell does that happen?). Couch does not sit flat and yes I’m aware it’s a pull out bed but the problem is the couch rear feet aren’t level. Entertainment center radio comes on randomly so we make sure the volume is all the way down so we don’t get woken up at 3am by what seemed like a ghost for the first couple weeks we owned the rv. Wiring issue with entertainment center including lights and sound system. Lights/ radio sometime stay on or cut on by themselves. Yes the lights too...wtf trim in basement drivers side rear storage door and inside coach is not installed properly, staples/glued to hold it in place.  (You can’t staple right? Lol. Does the manufacturer have 3 year olds putting these things together!!?) Bottom Grey water tank valve handle won't go in fully and the walls holding the valve handles aren’t secured so you gotta use one hand to hold the wall and another to push or pull the valve.   Kitchen Oven door does not close fully. We use a folding ladder pushed against the door when we use the oven. Living room small window on drivers side screen rubber messed up from the factory. 49 hours on the generator and the fuel pump broke so I replaced that. The air conditioners leak water. All three. The problem is I work a lot. Many many hours a week and I bought a $95,000.00 dollar rv thinking I would just have a big payment and not worry with having to fix stuff. But now I have a payment and a weekend repair list. It’s bs. Run away! This is just what I felt like writing down. There’s so many issues with this piece of s**t. We will never buy another grand design. Honestly grand design should give me about $65,000.00 of my $95,000.00 back. This rv might be worth $30 grand. I hope this helps people. Show less
